animal cells

Question 1

A network of membranes studded with ribosomes. Function: Synthesizes and modifies proteins destined for secretion or insertion into membranes.

Answer 1

Rough Endoplasmic Reticulum (RER)

Question 2

The control center of the cell, containing DNA. Function: Directs cell activities and stores genetic information.

Answer 2

Nucleus

Question 3

A dense region within the nucleus. Function: Produces ribosomes.
* Ribosomes: Small structures made of RNA and protein. Function: Synthesize proteins.

Answer 3

Nucleolus

Question 4

Membrane-bound sacs containing enzymes. Function: Break down cellular waste and debris.

Answer 4

Lysosomes

Question 5

Cylindrical structures involved in cell division. Function: Organize microtubules during cell division.

Answer 5

Centrioles

Question 6

The “powerhouses” of the cell. Function: Generate energy (ATP) through cellular respiration.

Answer 6

Mitochondria

Question 7

The outer boundary of the cell. Function: Controls what enters and exits the cell.

Answer 7

Plasma Membrane

Question 8

Small, membrane-bound organelles containing enzymes. Function: Break down fatty acids and detoxify harmful substances.

Answer 8

Peroxisomes:

Question 9

A stack of flattened membrane-bound sacs. Function: Modifies, sorts, and packages proteins and lipids

Answer 9

Golgi Apparatus

Question 10

A network of membranes without ribosomes. Function: Synthesizes lipids, detoxifies drugs, and stores calcium ions.

Answer 10

Smooth Endoplasmic Reticulum (SER)

Question 11

Hollow tubes providing structural support. Function: Provide cell structure and facilitate movement.

Answer 11

Microtubules
