Cell organelles & Their function

Question 1

Cell membrane

Answer 1

A flexible barrier that controls the movement of molecules, gases, and ions in and out of the cell. It is porous (semi-permeable) and only allows small particles to flow through.

Question 2

Nucleus

Answer 2

Contains DNA (genetic material); controls all cell activities.

Question 3

Mitochondria

Answer 3

Responsible for making energy in the form of ATP through the process of cellular respiration

Question 4

Ribosomes

Answer 4

Responsible for making proteins for the cell

Question 5

Chloroplasts

Answer 5

Converts light energy into chemical energy through the process of photosynthesis. Only found in plant cells.

Question 6

Cell wall

Answer 6

A rigid structure that surrounds the cell membrane. It provides support and protection for plant cells

Question 7

Vacuole

Answer 7

Stores water, food, and other substances for the cell. Large central vacuoles exist in plant cells; extremely small or not present in animal cells

Question 8

Lysomes

Answer 8

Contain digestive enzymes that help break down worn out cell parts to be disposed of by the cell

Question 9

Endoplasmic Reticulum

Answer 9

Smooth- Lacks ribosomes on its surface. Is attracted to the ends of rough ER. Makes cell products that are used inside the cell

Rough- Contains ribosomes. Involved with the transport of cell products and proteins outside of the cell

Question 10

Golgi Body

Answer 10

Appear as flattened stacks that modify, sort and package molecules from the endoplasmic reticulum

Question 11

Cytoplasm

Answer 11

Jelly-like substance that fills that cell and holds organelles in place
