Organelle Functions

Question 1

Plasma Membrane

Answer 1

Flexible, selectively permeable membrane boundary that helps control what enters and leaves the cell.

Question 2

Cytoplasm

Answer 2

Semi-fluid material inside the cell’s plasma membrane.

Question 3

Nucleus

Answer 3

In eukaryotic cells, the central membrane bound organelle that manages cellular functions and contains DNA.

Question 4

Nucleolus

Answer 4

Produces ribosomes inside the nucleus.

Question 5

Cell Wall

Answer 5

In plants, the rigid barrier that surrounds the outside of the plasma membrane, is made of cellulose, and provides support and protection to the cell.

Question 6

Golgi Apparatus

Answer 6

Flattened stack of tubular membranes that modifies, sorts, and packages proteins into vesicles and transports them to other cells or organelles.

Question 7

Mitochondria

Answer 7

Membrane bound organelle that converts fuel into energy that is available to the rest of the cell.

Question 8

Endoplasmic Reticulum

Answer 8

Highly folded membrane system in eukaryotic cells that is the site for protein synthesis.

Question 9

Vacuole

Answer 9

Membrane bound vesicle for temporary storage of materials such as food, enzymes, and wastes.

Question 10

Chloroplast

Answer 10

Double membrane organelle that captures light energy and converts it to chemical energy through photosynthesis.

Question 11

Ribosome

Answer 11

Simple organelle that helps manufacture proteins.

Question 12

Lysosome

Answer 12

Vesicle that uses enzymes to digest excess or worn out cellular substances.

Question 13

Cytoskeleton

Answer 13

Supporting network of protein fibers that provide a structural framework for the cell.

Question 14

Flagella

Answer 14

Long, tail-like projection with a whip-like motion that helps the cell move through a watery environment.

Question 15

Cilia

Answer 15

Short, hair-like projection that function in cell movement.
