Bio cell organelle functions

Question 1

CELL WALL

Answer 1

Protects and supports the cell and allows H2O, O2, CO2 to pass into and out of cell

Question 2

CELL MEMBRANE

Answer 2

• support
• protection
• controls movement of materials in/out of cell
• barrier between cell and its environment
• maintains homeostasis

Question 3

CYTOPLASM

Answer 3

-supports /protects cell organelles
-contains cytoskelon fibers

Question 4

NUCLEUS

Answer 4

-Controls all of the cell’s activities
-key organelle which has the genetic material and is involved in multiplication of cell, growth and maintenance of cell.

Question 5

NUCLEAR MEMBRANE

Answer 5

Controls movement of materials in/out of nucleus

Question 6

NUCLEOLUS

Answer 6

store Dna and houses genetic info

Question 7

CHROMATIN

Answer 7

Provides instructions for the cells activities, (growth, reproduction)

Question 8

ROUGH ENDOPLASMIC RETICULUM

Answer 8

• Synthesis of fats/lipids
• Ribosomes synthesis proteins for export

Question 9

SMOOTH ENDOPLASMIC RETICULUM

Answer 9

carries material through the cell

Question 10

RIBOSOME

Answer 10

synthesizes proteins

Question 11

MITOCHONDRIA

Answer 11

• breaks down sugar molecules into energy
• site of aerobic cellular respiration

Question 12

VACUOLES

Answer 12

• Vacuoles are pouches in the cell that store materials such as water, salts, proteins, and carbohydrates, waste products and toxic waste..
• store food, water, waste (plants need to store large amounts of food)

Question 13

CHLOROPLAST

Answer 13

Captures sunlight and uses it to produce food through photosynthesis

Question 14

GOLGI BODY

Answer 14

• to modify and package proteins for export
• have cis and trans face

Question 15

LYSOSOME

Answer 15

• breaks down larger food molecules into smaller molecules
• digests old cell parts

Question 16

CENTRIOLE

Answer 16

• separate chromosome pairs during mitosis

Question 17

FLAGELLA

Answer 17

Helps some single-celled organisms move.

Question 18

CILIA

Answer 18

Some cilia help single-celled organisms move, while others serve as sensory organelles.

Question 19

vesticles

Answer 19

• These help in storage and release of substances as required by the cell. For example lysosomes help in cell digestion when cell dies. Vacuoles function is to store water.
