Structures Of Cells

Front 1

Cell Wall

Back 1

a rigid layer of nonliving material that surrounds the cells of plants and some other organisms. A plant's one helps to protect and support the cell. It's mostly made out of cellulose.

Front 2

Cell Membrane

Back 2

Controls what substances come into and out of a cell. Everything the cell needs, from food to oxygen enters the cell through this. It also prevents harmful materials from entering the cell.

Front 3

Nuclear Envelope

Back 3

A membrane that surrounds and protects the nucleus.

Front 4

Chromatin

Back 4

thin strands containing genetic material

Front 5

Nucleolus

Back 5

a small object where ribosomes are made

Front 6

cytoplasm

Back 6

region between the cell membrane and the nucleus

Front 7

Mitochondria

Back 7

known as the "powerhouses" of the cell because they convert energy in food molecules to energy the cell can use to carry out its functions.

Front 8

Endoplasmic Reticulum

Back 8

passageways that carry proteins and other materials from one part of the cell to another

Front 9

Ribosomes

Back 9

Small, grainlike bodies that are attached to some surfaces of the endoplasmic reticulum. Others float in the cytoplasm. They function as factories to produce proteins.

Front 10

Golgi Bodies

Back 10

receive proteins and other newly formed materials from the endoplasmic reticulum, package them, and distribute them to other parts of the cell. They also release materials outside the cell.

Front 11

Vacuoles

Back 11

large, water-filled sac that floats in the cytoplasm; They are the storage areas of cells. They store food and other materials needed by the cell. They can also store waste products.

Front 12

Lysosomes

Back 12

small, round structures containing chemicals that break down certain materials in the cell. They also bread down old cell parts and release the substances so they can be used again.

Front 13

Nucleus

Back 13

the cell's control center; directs all of the cell's activities
