Question 3

What is the plant kingdom?

Answer 3

Plants are multicellular organisms. Eg: flowering plants like maize, or herbaceous legumes like peas.

Question 4

True or false? Plant do not carry out photosynthesis so they don’t have chloroplasts.

Answer 4

False!!! Plant cells do have chloroplasts so they carry out photosynthesis. They are autotrophic.

Question 5

Do plants cells have cell walls?

Answer 5

Yes, plant cells have cell walls, they are made out of cellulose; they store carbohydrates as starch or sucrose.

Question 6

What is the animal kingdom?

Answer 6

They are multicellular organisms; eg: mammals and insects.

Question 7

Do animal cells contain chloroplasts and carry out photosynthesis?

Answer 7

No, animal cells do not contain chloroplasts and carry out photosynthesis. They are heterotrophic.

Question 8

True or false? Animals cells normally have nervous coordination and are able to move from one place to another.

Answer 8

True!! Animal cells have nervous coordination and are able to move from one place to another.

Question 9

How do animals store carbohydrates?

Answer 9

Animals often store carbohydrates as glycogen.

Uni

Question 14

Is an a fungi multi or uni cellular?

Yes/No Yes in plant-like cells No in animal-like cells

Question 18

Does a prokaryote cell have a cell wall?

Answer 18

Yes

Question 19

Does a fungi cell have a cell wall?

Answer 19

Yes

Question 20

Can an animal cell photosynthesise?

Answer 20

No

Question 21

Can a plant cell photosynthesise?

Answer 21

Yes

Question 22

Can a protoctist cell photosynthesise?

Answer 22

Yes/No Yes if it is a plant-like cell No if it is an animal-like cell

Question 23

Can a prokaryote cell photosynthesise?

Answer 23

Yes/No No if it is a normal prokaryote cell Yes if it is a Cyanobacteria cell

Question 24

Can a fungi cell photosynthesise?

Answer 24

No

Question 25

What does Heterotroph mean?

Answer 25

A heterotroph is an organism that makes energy by eating/digesting other organisms.

Question 26

What does Autotroph mean?

Answer 26

An autotroph is a living organism that produces its own energy/food by photosynthesis.

Question 27

What is saprophytic feeding?

Answer 27

In a fungi, the hyphae release enzymes that digest the food and then it gets absorbed back into the plant. The fungi are also decomposers.

Question 28

What is the feeding mechanism of animal cells?

Answer 28

Heterotrophic

Question 29

What is the feeding mechanism of plant cells?

Answer 29

Autotrophic

Question 30

What is the feeding mechanism of protoctist cells?

Answer 30

Heterotrophic/Autotrophic Heterotrophic if they are animal-like cells Autotrophic if they are plant-like cells

Question 31

What is the feeding mechanism of prokaryote cells?

Answer 31

Heterotrophic/Autotrophic Heterotrophic if they are normal prokaryote cells Autotrophic if they are Cyanobacteria cells

Question 32

What is the feeding mechanism of fungi cells?

Answer 32

Heterotrophic because they are saprophytic feeders.

Question 49

What is fungi?

Answer 49

They are organisms that aren’t able to carry out photosynthesis.

Question 50

What is the fungi body structure?

Answer 50

Fungi’s body is usually organised into mycelium made from thread like structures called hyphea, which contains many nuclei.

Question 51

What are the 4 key facts about fungi?

Answer 51

– Their walls are made out of chitin – They store carbohydrates as glycogen –They are heterotrophs that use saprophytic feeding – They do not photosynthesise

Question 52

How are fungi shaped/formed?

Answer 52

Their body is usually organised into a mycelium made from thread-like structures called hyphae. These contain many nuclei

Question 53

What are the disadvantages of using stem cells in medicine?

Answer 53

-It is quite an expensive technique -they can be derived from embryos that do not belong to the patient, which can cause the body to reject them. -doesn’t agree with people’s ethics
