Looking Inside Cells

Cell structure:

1. Cytoplasm 2. E.R. 3. Nucleus 4. Mitochondrion 5. Cell membrane

A maze of passageways called the what carries proteins and other materials from one part to another.

E.R.

What receive proteins and other newly formed materials and distribute them to other parts of the cell

Golgi bodies

What are the small, round structures in cells break down large food particles into smaller ones.

Lysosomes

What produce most of the energy the cell needs to carry out its functions?

Mitochondrion

What are tiny call structures that carry out specific functions within cells

Organel

What function as factories to produce proteins

Ribosomes

In cells without cell walls, what forms the outside boundary that separates the cell from its environment.

The cell membrane

What role do the cell membrane and nucleus play in the cell?

The cell membrane is a outside boundary that separates the cell from its environment.One of the cell membrane's main functions is to control what substances come into and out of a cell. Nucleus works as the cell's control center, directing all of the cell's activities.

The rigid layer of nonliving material that surrounds plant cells is called

The cell wall

Strand of genetic material floating in the nucleus is called

The chromotin

The region between cell membrane and the nucleus is called

The cytoplasm

A large, oval structure that directs all of the cell's activities

The nucleus

The storage area of a cell is called

a(n) vacuole

Organelles called what capture energy from sunlight and use it to produce food for the cell

cloroplast
