Where are those powerpoints????

SO FAR I ONLY HAVE ONE PRESENTATION FROM THIS CLASS!!!!  IF IT ISN'T TO ME BY 8 AM, IT IS LATE!!!

MONDAY!!!!!!!!!

Today we started class by turning in our unit packet pages 33-34B and got a stamp for our color code on unit packet page 39. Next we worked on the flower lab for the rest of class, this lab is located on pages 41-44 in our unit packet. on these pages we looked at the structures with in the flower.

make sure to label the figure on page 41. next we ripped off the petals and looked at the inside of the flower. Then label the figure 2 on page 42.

Next do the following charts and questions based on the figures.

Homework:

Finish the flower lab on pages 41-44

dont forget lab quiz tomorrow on the leaf lab, the flower lab, roots and stems and any

other labs we have done in this unit.

3/17 thursday

Agenda

-Plant of the day

-Stations lab

Today the plant of the day was the air plant that grows on trees in a tropical area. it is an epiphyte whitc means it is not rooted in soil. it is also a trichomes whitch means it has a grayscale on its leaves to reflect the sun and prevent water from leaving . it is closeley related to the bromiliad and pinaple.

Over the last two days in class we did a lab with 9 different stations about roots stems and if a plant is monocot or dicot station 1, 2, 3, and 6 talk about vascular, nonvascular, and root hairs and how roots look microscopically. 4 and 5 is about trophism and 7, 8, and 9 are about mono and dicots .

Homework

-finish the lab

-4 questions and 4 answers for the first two pages of 23.5

3/15 Tuesday

Agenda:

-Plant of the day

-Photosynthesis review

-Photosynthesis Quiz

-Work on homework

Today in Biology, it was a simple day. We first reviewed the plant of the, which was a moss ball. Remember, it is no moss. It forms in specific lakes in Japan, Iceland, Scotland, and Estonia. They're not plants, they're algae. Moss balls are adapted to low light. Chloroplats are dormant unless the ball breaks apart.

Next, we reviewed photosynthesis, light reactions and everything we needed to know for our quiz.

After, the quiz Mrs. Stein gave us time to complete our homework.

Homework:

-Read 23.2 (669-671) and (674-677) w/ a Double Bubble Map "Root vs. Stem"

-National Park Project due 3/23

The next scribe is Aleko

3/14

Agenda

*Plant of the day

*Discuss pigment lab

*Finish photosynthesis (go over UP 81-85)

*Factors influencing photosynthesis UP 73-76

Homework

*UP 93-76

*Quiz tomorrow on photosynthesis

*National Park presentation due 8am on 3/23

Our homework for UP 73-76 is a lab but you don't need to have been in class to do it. The idea is that there is a lamp and a plant soaking in water. You put the lamp either close to the plant, or far away. Then, you look at the bubbles coming from the water that the plant is in and if there are more bubbles, more photosynthesis is being done. If there are less bubbles, less photosynthesis is being done. We know this because oxygen is a product of photosynthesis. You are supposed to compare and contrast the amount of photosynthesis/bubbles there are when the lamp is close to the plant or far away form the plant. On page 74, the chart is: Trial 1: 50 bubbles, 27 bubbles, and 78 bubbles. Trial 2: 62 bubbles, 24 bubbles, and 84 bubbles. Mrs. Stein gave us the answers to that chart because we are not actually doing the lab. Now, you just need to find the averages and do the rest of the pages.

 

We got back our Pigment lab and UP 81-85.

Pigment lab

We discussed the pigment lab in class. We decided that just because it looks like chlorophyll is the only pigment, doesn't mean that it is. There are many other pigments in leaves that are just not visible because chlorophyll over powers them. When the weather changes, chlorophyll breaks down and the other pigments (which were always there - you just couldn't see them) begin to show through.

UP 81-85 answers:

1. The light-dependent reactions take place within the thykloid membranes.

2. The light-independent reactions are also known as the Calvin Cycle

3. The energy carriers NADPH and ATP are produced during the light-dependent reactions.

4. In the light-dependent reactions, the gas oxygen is produced.

5. High-energy sugars are produced during the light independent reactions.

6. The light independent reactions take place in the stroma.

8. If there is no light coming into the chloroplasts, how will this affect the Calvin cycle? The Calvin cycle will NOT be affected because it is light independent, it doesn't need the light.

9. What effect does weather have on the process of photosynthesis? Photosynthesis will be slowed down if there is no sun or the temperature is too cold.

10. If you place a plant in a clear, sealed box, how could you use a measurement of the gases in the boxed air to measure the rate of photosynthesis? What gas would you measure? You would measure oxygen and/or carbon dioxide because oxygen is a product of photosynthesis and carbon dioxide is used in photosynthesis. So, if there was a lot of oxygen and a little carbon dioxide, you would be able to measure the rate of photosynthesis.

**NOTES**

Plant of the Day:

Sensitive Plant (Mimosa pudica)

We learned that the plant is sensitive to touch and when you touch it, the leaves cu

rl inwards. Scientists are not sure exactly why the plant does this. It might be a defense mechanism.

Electron Carriers

*Light energy "excites" electrons in chloroplasts

Light Reaction

*Chlorophyll absorbs light, and electrons become energized

*Water splits to produce H+ and O2

*Electron lose energy to form ATP

*ATP then goes to the Calvin Cycle

*H+ and NADP form NADPH

*these carry energy to Calvin Cycle

Calvin Cycle

*CO2 is added to a 5 carbon sugar

*Energy from NADPH and ATP are used to carry out reactions

*Produces glucose

It is REALLY important to know and understand this diagram of photosynthesis! Remember:

*This diagram takes place in the chloroplast.

*The light reaction takes place in the thykloid.

*A stack of thykloids is called a granum.

*The empty space in the chloroplast is called the stroma.

Chlorophyll Thursday and National Park Friday

Thrsday:
-Schedule:
1. Got a stamp for UP 67-68
2. Took Notes on Photosynthesis
3. Pigment lab

-Homework:
1. Finish Lab Analysis Questions
2. Read section 8.2 and 8.3 in the textbook and do a reading strategy of your choice or UP 81-85
3. Work on your national parks project

-The notes:
PHOTOSYNTHESIS OVERVIEW:
.Reactants: CO2, H2O, light energy
.Products: O2, C6H12O6
.Two reactions:
-Light reaction
-Calvin Cycle (light independent reaction)
.Chloroplast Structure:
-Thylakoid sacs contain chlorophyll
-Granum: Stacks of thylakoids
-light rxn
-Stroma: open space
-Calvin cycle

After we took notes we started the pigment lab (UP 69-72)
-We started by taking 2 leaves (a Spinach Leaf and a Coleus Leaf)
-We rolled a dime over the leave so that we could get pigments onto a Chromatography paper
-We then rolled dup our paper, stapled it, and put it into a substance for 10 minutes.
-When we took the piece of paper out, we saw many layers of colors
-These colors were the pigments found in the plant.
-On the paper with the pigments of the spinach leaf the layers of colors went:
.Bright green
.Yellow green
.Bright green
.Yellow
.Faint yellow
-Then on the paper with the pigment from the Coleus leaf the layers of color were:
.Red
.Yellow green
.Green
.Faint yellow
.Yellow
This shows us that even though the leaf may appear to be green or red, there are many other pigments in the leaf. So just because the Coleus leaf appears to be red, there is still chlorophyll in it to help carry out photosynthesis.


Friday's ClassWe met in the classroom first to write down our homework and learn about power points

-Homework:
1. National Park DUE 3/23(UP 9)
2. Read pg 643+ pg 664-666
-I would suggest you take some notes because Ms.Stein will not go over the lesson in class
3. Review photosynthesis links (can be found on moodle)
-Before we went to the computer lab we learned about power points
1. Make sure the background color is:
-No too bright
-Colorful
-No too distracting
2. Make sure the font is:
-Big and easy to read
-The color does not blend into the background
-Try to follow the 5X5 rule (5 bullet pints and five words per bullet point on your slide
3. Make sure you don't make too many slides on animals
-Your information on animals should be short and brief whereas your information on plants should be longer and in detail

Friday was the last day of time that we would spend in class working on our project. From now on you should try to meet after school with your group to work on it.
Good Luck and sorry this was late!!

Weby wednesday!

Today in class we wrote down our homework, did the plant of the day, then did UP page 61 in class with our lab groups. Then we got a head start on our homework which was up pages 67-68.

Plant of the day;

Spider plant

-Self-propagating

"plantlets" (aka "spider babies") can take root in soil

- Produces fleshy tuberous roots

-Native to South Africa

-Common houseplant

-Produces white flowers

Notes about energy

What is energy?

The ability to do work

It can change form

It is never destroyed or created

Forms of energy;

Light, electric, and chemical

Chemical energy is stored in the electrons of the chemical bonds

Energy is used to do everything in living things

What do we know about photosynthesis?

It converts energy

Plants do it

Requires sunlight, carbon dioxide and oxygen

Describe the structures of a leaf that allow it to carry out the function of photosynthesis.

It is flat to absorb sunlight and has a spongy mesophyll that allows carbon dioxide in

Has chloroplasts

Has veins that are made up of 2 tissue, phloem-carries sugar away from the leaf and Xylem which carries water

A cuticle that prevents water loss

and a palisade mesophyll that has lots of chloroplasts at the top

Why should you wear a white shirt on a hot day, not a dark shirt?

The white shirt reflects all sunlight while the black shirt absorbs all sunlight

Notes about Lights and pigments;

Light travels in waves

Colors have different wave lengths

"white" light is a mixture of all colors in the visible spectrum

plant pigments absorb sunlight

chlorophyll- green pigment needed for photosynthesis

Hope that helps!

The next scribe will be Emma.

Terrific Tuesday

Plant of the day...

VENUS FLY TRAP (Dionaea muscipula)

THE PLANT KINGDOM

LEAVES
Leaves are the main photosynthetic organ in plants.
Blade- The flat part of the leaf
Petriole- the stem
cuticle-helps conserve water
3 types of tissue:
1) epidermis- protect the inner tissue
2)mesophyll- most of the photosynthesis takes place
3)vascular- were the xylem and the phloem

TODAY...
Today we did a leaf lab. The objectives of the lab is
1) to study the tissues that make up the leaves of a plant
2) examine the structure of a stomate
