Nucleus ­ controls all the activities, contains
instructions for making new cells and organisms.
Cytoplasm ­ liquid gel where chemical reactions
take place i.e respiration
Cell membrane ­ controls the passage of
substances in and out of cell
Mitochondria ­ structures in the cytoplasm where
oxygen is used and most of the energy is released
during respiration
Ribosomes ­ where protein ­synthesis takes place,
all proteins needed in the cell are made here.…read more

because contain green substance
chlorophyll which absorbs light energy to
make food via photosynthesis

Fat cells are storage cells and important when
the body is in short supply.
Little cytoplasm for room for fat
Few mitochondria as little energy is needed.
Can expand up to 1000 times its original size as
it fills.…read more
