chitin

Question 17

what do multicellular fungi have a body organised into

Answer 17

mycelium made of thread-like structures called hyphae which contain many nuclei

Question 18

how do fungi obtain food

Answer 18

secreting digestive enzymes on to food material and absorbing all organic products (saprophytic nutrition)

Question 19

Answer 19

glycogen

Question 20

via spores

Question 21

fungi examples

Answer 22

uni

Question 23

pathogenic protoctista example

Answer 23

plasmodium, responsible for causing malaria

Question 24

are bacteria uni or multicellular

Answer 24

uni

Question 25

what are bacteria cell walls made of

Answer 25

murin

Question 26

how do bacteria obtain food

Answer 26

• from other living organisms, either as parasites or by causing decomposition
• some contain chlorophyll so can carry out photosynthesis
• most bacteria feed off dead organisms - decomposers
• some will feed off living organisms

Question 27

do bacteria have a nucleus

Answer 27

no, they have a loop of DNA instead

Question 28

bacteria examples

Answer 28

lactobacillus, pneumococcus

Question 29

how do viruses reproduce

Answer 29

inside a host cell

Question 30

what is a viruses cellular structure

Answer 30

no cellular structure but do contain a loop of DNA or RNA inside a protein coat

Question 31

nucleus or cytoplasm in a virus?

Answer 31

none

Question 32

virus examples

Answer 32

influenza, HIV, measles, polio

Question 33

how do viruses work?

Answer 33

1. enters the host cell
2. takes over the hosts genetic machinery to make more virus particles
3. host cell dies, particles are released to infect more cells
4. usually, the body’s immune system destroys the virus and the person recovers
