Terrific Tuesday

Plant of the day...

VENUS FLY TRAP (Dionaea muscipula)
Carnivorous-insectivore

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

HOMEWORK

finish lab 25 "the structure of a leaf"

REMINDER

do research for the plant power point.

ALSO...

Tomorrow is twin day for Dr.Sues week

MICHEAL L is the next Scribe!

Another Tuesday

-most are unicellular some multicellular

-heterotrophic or autotrophic(photosynthesis)

-very diverse kingdom

ex. amoeba, paramecia

-eukaryotic

-single celled or multicellular

-cell wall made of chitin

-heterotrophs, decomposers

ex. yeast, mushrooms, mold

Kingdom plantae

-eakaryoric

-multicellular

-autotrophic

-cell wall made of cellulose

Kingdom Animalia

-eukaryoric

-multicellular

-heterotrophic

-no cell wall

SHARK LAB

Today we did a biological key lab. Classification is a way to separate large groups of closely related organisms into smaller subgroups. The key to making a biological key is listing specific characteristics, such as structure and behavior, in a way the organism can be identified.

In this lab we...

(a) used key to identify 14 shark families

(b) study how to make a key

(c) constructs our own key for the fish and leaves(needles)

HOMEWORK

finish UP 9-12(shark lab)

read 26.1

REMINDERS

T.V. add due 2/28

invertebrate project due 2/22

Sam is our next scribe

Malaria Monday

Today in class...

Today in class, we finished our two labs with the bacteria that we started on Friday. On Friday the lab groups went around and collected bacteria with cotton swabs. We collected 4 samples from 4 different places. Then we put the samples in a petrie dish. After the petrie dishes were in incubation for 24-48 hours we took them out and saw how much bacteria had grown on them. My lab group had a very interesting outcome.

On Friday we collected samples from the steps of the new pit, the door handle of the library, the boys' bathroom and then we had a control sample. Today when we looked at our petrie dishes we saw that the petrie dish from the stairs had the most bacteria growing on it.

We also finished the second lab that we started Friday using antibiotics. On Friday, we put peppercorn broth on the petrie dish and then we added 4 different antibiotics in different sections on the petrie dish. After incubation we saw the results today. For my group, the neomycin had the strongest impact on the bacteria.

Today we also had our Disease of the day.

Today our disease of the day was...

Malaria

-The agent of disease is protist

-transmitted by mosquito bites

-attacks the human liver

-prevented by bug repellents and reduction of standing water

Homework...

- finish UP 13-18- due tomorrow

-read section 35.2 and 1st page of 35.3 about immune systems and use the note taking skill tree maps-due Wednesday

reminders...

-postcard is due next Monday November 8

-Test next Tuesday November 9

T.G.I.F.

Today in class…

We finished up our mitosis lab with the onion cells and turned in pages UP44-51. We talked more about mitosis and what it is.

Mitosis

*Have 4 stages

Prophase-

-Chromosomes condense

-Nuclear membrane disappears

-Spindle fibers form as centrioles move toward the poles.

Metaphase-

- Chromosomes line up along the cell center

- Chromosomes attach to spindle fibers at the centromers

Anaphase-

-Sister chromatids separate and move toward the poles.

Telephone-

-Last step of mitosis

-Individual chromosomes gather at poles

-Nuclear membrane reforms

cytokinesis

-Cell pinches in half

-Two cells form

*Animal cell-cleavage furrows

Here’s a video on mitosis…

Homework

-Read pages 43-44 in text book

-Read section 10.3 and read UP 52B-52D and use the flow map note taking skill about the “causes/effects of unregulated cell cycle.”(Go on moodle or look in your packet for the outline of the flow map)

Reminders!!!

- Create a student account by Tuesday

- Cancer paper due October 25

- Cell test on Wednesday!!!

Cell test

*Look over labs and make sure you understand them!!

-Enzyme pre lab

-Mitosis lab

-Plasmolysis lab

-Cell structures and function lab

* Reread the sections in the book about cells

*Look over cell quiz
