Cell Parts

Question 1

Cell Membrane

Answer 1

Outer membrane of cell that controls movement in and out of the cell. It has double layers.

Question 2

Cell Wall

Answer 2

Plant cells only - supports and protects cells

Question 3

Nucleus

Answer 3

Directs cell activities
Separated from cytoplasm by nuclear membrane.
Contains genetic material, DNA.

Question 4

Nuclear membrane

Answer 4

Surrounds nucleus.
Made of two layers.
Openings allow material to enter and leave nucleus.

Question 5

Chromosomes

Answer 5

In nucleus.
Made of DNA.
Contain instructions for traits and characteristics.

Question 6

Nucleolus

Answer 6

Inside nucleus. Contains RNA to build proteins.

Question 7

Cytoplasm

Answer 7

Gel-like mixture. Surrounded by cell membrane. Contains hereditary material.

Question 8

Endoplasmic Reticulum

Answer 8

Moves materials around in cell. Smooth type: lacks ribosomes. Rough type has ribosomes embedded in surface.

Question 9

Ribosomes

Answer 9

Each cell contains thousands. Makes proteins. Found on ribosomes and floating throughout cell.

Question 10

Mitochondria

Answer 10

Produces energy through chemical reactions - breaking down fats and carbohydrates. Controls level of water and other materials in cell. Recycles and decomposes proteins, fats, and carbohydrates.

Question 11

Golgi bodies

Answer 11

Protein packaging plant. Moves materials within the cell. Moves materials out of cell.

Question 12

Lysosome

Answer 12

Digestive plant for proteins, fats, and carbohydrates. Transports undirected material to cell membrane for removal. Cell breaks down if lysosome explodes.

Question 13

Vacuoles

Answer 13

Membrane-bound sacs for storage, digestion, and waste removal. Contains water solution. Helps plants maintain shape.

Question 14

Chloroplast

Answer 14

Usually found in plant cells. Contains green chlorophyll. Where photosynthesis takes place.
