Answer 3

Mine by pseudopods

Unicellular organism

Question 4

Algae

Answer 4

Large and diverse group of plant

Range from Unicellular to multi cellular

Question 5

Paramecium

Answer 5

Consists of a single cell

Visible to the naked eye

Question 6

Ameoba

Answer 6

Single cell
Consumer
Hererotrophic
Lives in fresh water
Constantly changing shape
Ecto+ endoplasm 
Contradicile vacuole 
Pseudopod
Food vacuole

Question 7

Ectoplasm

Answer 7

Outer cytoplasm (jelly)

Question 8

Endoplasm

Answer 8

Inner cytoplasm (fluid)

Question 9

Contractile vacuole

Answer 9

Regulates water (osmoregulation)

Question 10

Pseudopod

Answer 10

Moves ameoba and engulfs food

Question 11

Food vacuole

Answer 11

Secretes avid and enzymes

Question 12

Endoplasm appearance

Answer 12

Grainy due to the presence of food vacuole and waste materials

Question 13

Ectoplasm appearance

Answer 13

Clear and firm

Question 14

How does ameoba feed

Answer 14

By engulfing it’s prey with pseudopodia
Acid then released to kill prey
Enzymes then secreted into the vacuole
Food can then be stored within the vacuole

Question 15

Osmoregulation

Answer 15

The process of maintaining salt and water balance (osmotic balance) across membranes within the body

Question 16

Explain cycle of osmosis moving into ameoba cytoplasm

Answer 16

Ameoba cytoplasm is more concentrated than the fresh water around it
As a result, fresh water rushes intibut by osmosis
To deal with this, ameoba forms a contradiction vacuole (where excess water enters)
It swells with water
It burts and expels water
The cycle is repeated
