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.
