Unit 2 Flashcards
what features do animal and plant cells share
cell membrane
cytoplasm
DNA/Nucleus
what is cytoplasm
jelly like substance that contains other structures
site of most chemical reactions in the cell
what is the nucleus
contains the cells DNA and controls the activities of the cell
what features do plant cells have
cell wall
cell membrane
vacoule
nucleus
chloroplast
cytoplasm
what is the vacoule
fills most of the cell and contains cell sap
helps the cell stay rigid and stores some substances
what is the cell wall
fibers form a mesh outside the cell membrane
provides shape and support to the cell
prevents it from bursting when it absorbs water
what are chloroplasts
contains chlorophyll, found in the cytoplasm
site of photosynthesis and contains starch grains that can act as food stores
what are other structures found in cells
Rough endoplasmic reticulum
ribosomes
mitochondria
what are ribosomes
they are found on RER and is the site of protein synthesis
what are mitochondria
they are found in both plant and animal cells
where respiration takes place and energy is released
where are high amounts of mitochondria found
cells that require high rates of metabolism
formula for magnification
magnification = image size/actual size
