Genetic Material. …
Ribosomes. …
Cytoplasm. ..

Question 2

what are the major forms of life on earth

Answer 2

animals, plants, protists, bacteria

Question 3

characterics of protists

Answer 3

eukarototic, most unicelluar, some heterotrophic, ‘junk drawer kingdom.’

Question 4

plants

Answer 4

Eukaryotic
Always Multicellular
Always Autotrophic
Always have a cell wall
Many have a more
regular shape “brick-like”
Green Chloroplasts MAY
be visible

Question 5

animals

Answer 5

Eukaryotic
Always Multicellular
Always Heterotrophic
Do not have a cell wall
shapes vary greatly
depending on type of cell

Question 6

bacteria

Answer 6

Prokaryotic
Always Unicellular
live together in large groups
Cannot see any internal
structures
Most are Heterotrophic,
some are Autotrophic
3 common shapes
round - “cocci”
rod - “bacilli”
spiral - “spirilli”

Question 7

Fungi

Answer 7

Eukaryotic
Most are Multicellular, some are unicellular (yeast)
Always Heterotrophic
(like animals)
Always have a cell wall
(like plants)
