Answer 12

no nucleus or organelles (little compartmentalisation)

Question 13

What is the size and complexity of a prokaryotic cell like?

Answer 13

small and simple

Question 14

what does bacteria act as?

Answer 14

decomposer, make humans sick, make food

Question 15

Where does bacteria live in our body?

Answer 15

gut and skin

Question 16

What does bacteria in our gut do?

Answer 16

helps digest food

Question 17

What does bacteria on our skin do?

Answer 17

Protects us from harmful bacterial infections

Question 18

What is cyanobacteria?

Answer 18

They’re special because they can perform photosynthesis

Question 19

What is photosynthetic bacteria the precursor to?

Answer 19

modern-day chloroplast organelles

Answer 25

linear

Question 26

what are protists?

Answer 26

single-celled eukaryotic organisms that don’t fit animal, plant, or fungal kingdoms

Question 27

Answer 27

modern animals, plants, fungi

Question 28

What do protists contain?

Answer 28

special organelles

Question 29

What is cilia?

Answer 29

small hair like structures

Question 30

What does cilia do?

Answer 30

Allows the cells to move through water

Question 31

What does the cytostome do?

Answer 31

it functions like a mouth

Question 32

What does the phagosome do?

Answer 32

it functions like a stomach

Question 33

What does the contractile vacuole do?

Answer 33

it helps pump extra water out of the cell

Question 34

How do protists reproduce?

Answer 34

through asexual reproduction through cell division
can also reproduce sexually for more genetic variation

Question 35

name members of the kingdom protista

Answer 35

diverse eukaryotes (algae, protozoa)

Question 36

are protists unicellular or multicellular

Answer 36

most are unicellular, but algae tend to be multicellular

Question 37

Can protists move?

Answer 37

yes, using flagella, cilia, and footlike extensions

Question 38

What are some protists considered the ancestors of?

Answer 38

multicellular plants, animals, fungi

Question 39

Why was the kingdom protista developed?

Answer 39

to accommodate intermediate organisms that possessed some plant/animal characteristics, but not the specialised features
