Description
Function
Strong, stiff, nonliving layer
outside the cell membrane; can
be made of cellulose
Outermost living layer of the
cell; elastic and flexible;
contains pores
Region between the nucleus and
the cell membrane; consists of a
jellylike substance that contains
many organelles
Large, oval structure in the
center of the cell; bounded by
the nuclear membrane; contains
the chromosomes(DNA) and
nucleolus
Small dark area in the nucleus
Series of fibers made from
proteins; located near the cell
membrane
System of clear, tubular
passageways; spreads through
cytoplasm
Small, grain like body made
primarily of RNA, may be
attached to ER or floating free in
cytoplasm; produced in
nucleolus
Rod-shaped organelle; located in
cytoplasm; has a smooth outer
membrane and a greatly folded
inner membrane
Large, round water-filled sac in
cytoplasm
Small, round sac in cytoplasm;
contains digestive enzymes
Large green structure in
cytoplasm; contains chlorophyll
Resembles ER; closer to cell
membrane
