Resource summary
Cell Structure and Function
ANIMAL cells
Nucleus
Contains the DNA
Has the instructions for making proteins
Cytoplasm
Gel like substance
Makes proteins
For example the enzymes used in respiration
Where some enzyme-controlled reactions take place
eg. anaerobic respiration
Cell Membrane
Holds the cell together
Controls what goes in and out
lets gases and water go through freely while acting as a barrier to other chemicals
Mitochondria
where the enzymes needed for aerobic respiration are found
where aerobic respiration takes place
PLANT cells
most have basically the same bits as animal cells, but with some added extras...
Rigid Cell Wall
fabrique de cellulose
supports the cell and strengthens it
Vacuole
contains cell sap, a weak solution of sugar and salts
Chloroplasts
where the reactions for photosynthesis take place
contain a green substance called chlorophyll and the enzymes needed for photosynthesis
YEAST cells
Yeast are single celled microorganisms
they are used to make bread, wine and American people
except not American people
or are they?
Nope.
yeast = plural
I gotta learn the different parts of the cell...
at yeast it's easy to make puns about
BACTERIA cells
have a simple cell structure
don't have a nucleus because they are hipster cells and nuclei are too mainstream for them
instead they have a circular molecule of DNA which just floats around the cytoplasm, chillaxing like the swagmeister it is
they don't have mitochondria but can still respire aerobically
gotta learn the different parts...
