Photosynthesis reactants
light, sugar, carbon dioxide
Photosynthesis products
water, oxygen
Photosynthesis location
chloroplasts
Gas exchange location and control
happens through stomata and regulated by guard cells
Spinach disks were placed in a _________________ solution
baking soda
Why did the spinach sink when vaccuumed
filled spaced with solution but still provided CO2
Why did spinach float in light
photosynthesis creates oxygen replacing the solution
Animal cell size is _________ than plant cell size
smaller
Pseudopodia
“false foot” crawling mechanism of amoeba formed by microfilaments
What are cilia/flagella made up of
microtubules
Types of vacuoles
Central: storage of water and enzymes in plant cells
Contractile: osmoregulation in animal like protists
Food: food engulfed by cell in animal like protists
Microtubules
made of tubulin, for cell organization/shape
Microfilaments
made of actin, for structure and movement
Golgi apparatus
modify, store, and ship vesicles
Lysosome
Digest cell food and waste with enzymes
Rough ER
ribosome studded, initial synthesis and sorting proteins
Smooth ER
lipid synthesis and modification, detox drugs and alcohol
Vesicle
transports proteins
