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

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
