COMMON CELL TRAITS
A cell is the smallest unit that is capable of performing life functions.

COMPARING CELLS
The size & shape of a cell relates to its function. (job it does)

Prokaryotic Cells(proh KAYR ee yah tihk)
cells without membrane-bound structures
EX: bacteria
pond scum

Eukaryotic Cells(yew KAYR ee yah tihk)
cells with membrane-bound structures
EX: animals, plants, fungi and protists

protects the cell gives shape is made of cellulose A cell wall is found in plants, algae, fungi, & most
bacteria.
CELL WALL

CELL MEMBRANE
Outer covering, protective layer around ALL cells
For cells with cell walls,the cell membrane is inside the cell wall
Allows food, oxygen, & water into the cell & waste products out of the cell.

CYTOPLASM
gelatin-like inside cell membrane constantly flows aka protoplasm

CYTOSKELETON
scaffolding-like structure in cytoplasm
helps the cell maintain or change its shape
made of protein

NUCLEUS
Directs all cell activities Contains instructions
for everything the cell does
These instructions are found on a hereditary material called DNA
Usually the largest organelle

NUCLEAR MEMBRANE
separates nucleus from cytoplasm
controls movement of materials in & out of nucleus

NUCLEOLUS
Aka “little nucleus” Found in the nucleus Site of Ribosome
production

CHROMATIN
contains genetic code that controls cell made of DNA & proteins
