2.1 - Organisation of organisms

Question 1

Animal Cell

Answer 1

Has a round irregular shape

Question 2

Plant Cell

Answer 2

Squarish/ rectangular shape

Question 3

Cell Organelle

Answer 3

Structure that performs a particular function in the cell

Question 4

Animal Cell Organelles

Answer 4

• Cell Membrane
• Cytoplasm
• Mitrichondria
• Nucleus
• Ribosome
• Rough and Smooth Endoplasmic Reticulum

Question 5

Plant Cell Organelles

Answer 5

Contains all the organelles in an animal cell with the addition of:

• Cell Wall
• Chloroplast
• Vacuole

Question 6

Cell Membrane

Answer 6

This is a layer of fat and protein surrounding the cell

It is semi permeable and allows certain substances to go through the the cell

Question 7

Cytoplasm

Answer 7

This is a jelly like substance inside the cell where the cell organelles are stored

Question 8

Mitochondria

Answer 8

This is a rod shaped organelle with a double membrane
It converts energy into adenosine triphosphate (ATP) for use in the cell
Powerhouse of the cell

Question 9

Nucleus

Answer 9

Spherical organelle surrounded by nucleus membrane
Controls the functions of the cell
Contains DNA (genetic material) chromosomes and ribosomal RNA

Question 10

Ribosome

Answer 10

Small organelle composed of RNA

Question 11

Rough and Smooth Endoplasmic Reticulum (ER)

Answer 11

Rough ER - Produces proteins and transfer materials. Covered with ribosomes that give it a rough appearance

Smooth ER - Produces lipids and membrane proteins

Question 12

Cell Wall

Answer 12

A thick rigid membrane surrounding the cell

Made of cellulose fibre and gives the plant its structure

Question 13

Chloroplast

Answer 13

Disc shaped organelle containing chlorophyll and carries out photosynthesis
Has green pigments

Chlorophyll- Molecule that is a catalyst for photosynthesis

Question 14

Vacuole

Answer 14

Large membrane bound cell filled with fluid (mostly water)

Helps maintain water levels in the cell and the shape of the cell
