Cell Type and Requirements

Question 1

What is a cell?

Answer 1

A cell is the basic structural unit of all forms of life on Earth

Question 2

What are the three points of cell theory?

Answer 2

1. The cell is the most basic unit of life
2. All cells arise from pre-existing cells
3. Every living organism is made up of one or more cells.

Question 3

What are the two main types of cells?

Answer 3

Prokaryotic and Eukaryotic

Question 4

What is an example of a Prokaryote?

Answer 4

Bacteria

Question 5

What is an example of a Eukaryote?

Answer 5

Animals, plants and fungi

Question 6

What are Prokaryotic cells?

Answer 6

Simplest type of cell, they have difficulty performing multiple tasks at once because it lacks membrane bound organelles.

Question 7

What are organelles?

Answer 7

Specialized structures within a cell that perform specific functions.

Question 7

What are eukaryotic cells?

Answer 7

More complex type of cell, it is made up of organelles that perform specialised functions.

Question 8

Cytoplasm

Answer 8

Chemical reactions are carried out here.

Question 9

Endoplasmic Reticulum

Answer 9

Smooth- carries out multiple functions, including the synthesis of membrane phospholipids
Rough- Contains ribosomes.

Question 10

Golgi Apparatus

Answer 10

Collects, packages, modifies and distributes proteins.

Question 11

Lysosomes

Answer 11

Breaks down foreign substances and old, worn out organelles (contains digestive enzymes)

Question 12

Nucleus

Answer 12

Contains the cells DNA

Question 13

Mitochondria

Answer 13

Site of aerobic respiration

Question 14

Ribosome

Answer 14

Site of protein synthesis

Question 15

Chloroplasts

Answer 15

Site of photosynthesis.

Question 16

Large Vacuole

Answer 16

Stores water, nutrients, metabolic waste and toxins.

Question 17

Cell Wall

Answer 17

Protects the plant cell, maintains it shape and prevents excessive uptake of water.

Question 18

What organelles do prokaryotes contain?

Answer 18

Cytoplasm, Ribosomes, Genetic Material

Question 19

Compare Eukaryotic and Prokaryotic Cells

Question 20

Compare Animal and Plant cells

Answer 20

Plant cells contain chloroplast, large vacuoles and a cell wall, have a fixed rectangular shape, store energy as starch and perform photosynthesis.

Animal Cells contain lysosomes, smaller vacuoles and centrioles, they often have a rounded, irregular shape, store energy in glycogen and perform respiration.
