Decomposers - breakdown dead and decaying matter

Question 33

Bacteria carbohydrate storage

Answer 33

Glycogen

Question 34

Prokaryote bacteria cell examples

Answer 34

Lactobacillus Pathogenic - salmonella

Question 35

Viruses are not

Answer 35

A cell

Question 36

Virus diagram

Answer 36

Loop of DNA/RNA Capsid Attachment protein - so it attacthes to other cells Envelope sometimes

Question 37

Capsid in virus cells

Answer 37

Protein coat that surrounds nucleic acid and protects it

Question 38

Why are viruses not considered living

Answer 38

Pathogenic always - injects nucleic acid (DNA/RNA) into host cell and takes over metabolic pathways to make more copies of genetic info/nucleic acids/themselves So its not living since they cannot reproduce unless inside host cell

Question 39

Virus examples

Answer 39

HIV (causes AIDS) /tobacco mosaic virus

Question 40

Tobacco mosaic virus

Answer 40

Causes mosaic pattern on leaf - discolouration Affects chloroplasts and photosynthesis Prevents growth

Question 41

Eukaryotic

Answer 41

Membrane bound organelles Nucleus Animal/fungi/plant/protoctista

Question 42

Prokaryotic

Answer 42

No membrane bound organelles Loop of DNA Bacteria
