sea water

Question 4

Answer 5

heterotrophic: takes in food (cannot make own food)

Question 6

Do amoeba produce sexually or asexually?

Answer 6

asexually

Question 7

Answer 7

eukaryotic

Question 8

Are amoeba eukaryotic or prokaryotic?

Answer 8

eukaryotic

Question 9

Are amoeba herbivores/carnivores/omivores? Explain.

Answer 9

omnivorous: eats other single-celled protists, plants, animals

Question 10

Name two examples of protista.

Answer 10

amoeba, algae

Question 11

Amoeba move by means of?

Answer 11

pseudopods

Question 12

What is the protoplasm?

Answer 12

all living material in the cell

Question 13

What surrounds the protoplasm?

Answer 13

flexible membrane

Question 14

Whats the function of pseudopodia?

Answer 14

extend in the direction the amoeba wants to move & surrounding prey

Question 15

Function of contractile vacuole? Whats this known as?

Answer 15

collects excess water that enters the cell by osmosis and removes it without bursting the cell = osmoregulation

(gets rid of excess water)

Question 16

Function of food vacuole?

Answer 16

releases enzymes to digest prey

Question 17

Whats another name for pseudopodia?

Answer 17

false feet

Question 18

Function of cell membrane?

Answer 18

retains the cell contents

Question 19

Comment on cell membranes permeability.

Answer 19

selectively permeable

Question 20

Function of nucleus?

Answer 20

controls cell activities

Question 21

Describe the endoplasm.

Answer 21

inner part of cytoplasm, grainy due to food vacuoles and fat being present here

Question 22

Location and function of ectoplasm?

Answer 22

outer part of cytoplasm, soft to allow movement

Question 23

Difference between the locations of ectoplasm and endoplasm?

Answer 23

endoplasm: inner part of cytoplasm

ectoplasm: outer part of cytoplasm

Question 24

Whats responsible for osmoregulation in amoeba?

Answer 24

contractile vacuole

Question 25

Whats osmoregulation?

Answer 25

the regulation/control of osmosis

Question 26

Is the cytoplasm more, the same or less concentration that the water outside?

Answer 26

its more concentrated

Question 27

How does water enter amoeba?

Answer 27

osmosis

Question 28

Without the contractile vacuole what would happen the amoeba?

Answer 28

expand and burst the whole cell

Question 29

If amoeba were placed in a salty water environment, what would happen the water?

Answer 29

would rush out of the cell and shrivel

Question 30

Give 4 ways the cell of amoeba differs to a bacterial cell.

Answer 30

1: amoeba is eukaryotic, bacteria are prokaryotic. 2: amoeba have a nucleus, bacteria do not. 3: amoeba have contractile vacuoles, bacteria do not. 4: amoeba have pseudopods, bacteria do not.
