cells Flashcards
cell membrane
controls the entry and exit of chemicals in and out of the cell
cytoplasm
where chemicals dissolve in water and the reactions take place here
nucleus
controls the cells functions and contains genetic material
(red blood cells don,t have a nucleus)
chromosomes
found in the nucleus
contains DNA
mitochondria
where respiration takes place
cell wall
to support and give shape to the cell
made of cellulose
vacuole
contains water and provides support
chloroplasts
contain chlorophyll where photosynthesis takes place
organisation of cells
cells - tissue - organ - organ system
total magnification
eye lens power x objective lens power
cuticle
waxy layer prevents evaporation
transparent
epidermis
has no chloroplasts
palisade mesophyll
cells with many chloroplasts
most photosynthesis happens here
spongy mesophyll
cells with air spaces and fewer chloroplasts
guard cell
allows gas exchange
