A

Bacteriophages

21
Q

How do new strains of flu arise?

A

22
Q

Protists

A

Most ancient Eukaryote, not Fungi, plants or animals.

23
Q

Why are protists important to humans?

A

Most diseases caused by protists, make up both good and bad algae.

24
Q

Fungi

A

They look like plants but lack chlorophyll and no photosynthesis

25
Q

Why are fungi important to humans?

A

There are many commercial uses and they are decomposers.

26
Q

4 key aspects of plant evolution

A
  1. Alternation of generations
  2. Vascular Tissue
  3. Seeds
  4. Flowers and Fruits
27
Q

Vascular vs. non-vascular plants

A

Tubes/pipes to transport water and nutrients

28
Q

Gymnosperms

A

Most ancients plants, 4 types, most common today are conifers. Produce seeds in cones, use wind pollination.

29
Q

Angiosperms

A

90% of plants today. Animal pollination. Ovule is completely enclosed by sporophyte tissue when it is fertilized.

30
