photosynthesis Flashcards
what is photosynthesis
the process of convertigsunligh into energy
what is the word equation for photosynthesis
carbon dioxide + water = glucose + oxygen
light
where does photsynethesis take place in a plant
in the chloroplasts
how are plants adpapted for photosyntheiss
- has chlorophyll to get in sunlight
- the stomata to allow gases in and out of the plant
- has a large surface area to maximize diffusion
how does water get into the cell
water diffuses into the root hair cell and has large surface area to maxiemise diffusion and is then transported through the xylem tubes
how do gases get into and out of the plant
there are tiny holes on the underside of the leave and these allow for the gases to diffuse in and out
what is in a animal cell
- nucleus
- cytoplasm
- mitochodnria
- cell membrane
what is in a plant cell
- cell wall
- cell membrane
- cytoplasm
- vacuole
- nucleus
- chloroplasts
how are algae different from plants
- uni cellular or multi-cellular organism
- live underwater
- do not have leaves, stems or roots
what does chlorophyll do
absorbs sunlight from sun for photsynthesis
What is biotechnology
The use of biological processes or organisms to create useful products.
Give two necessary condition need for photosynthesis to take place
- light
- nutrients
Who do green plants need glucose
- to create energy
- respiration
- starch
What is the purpose of the guard cell
Allows movement of carbon dioxide and oxygen in and out of the plant
What is the purpose of a palisade cell
It is near the surface of the leaf and contains the most chlorophyll
