Animals

4

Flagellated single cell ancestors diverged how long ago?

1 BYA

5

__________ are absorptive heterotrophs.

Fungi

6

Absorptive heterotrophs secrete __________.

Exoenzymes

7

Fungi exhibit many different lifestyles, such as:

Decomposers, parasitic, mutualistic

8

Fungi are _____ celled and __________.

Single-celled, multicellular

9

An example of a single celled fungi is __________.

Yeast

10

Yeasts reproduce via __________.

Asexual budding

11

__________ digest food outside the body.

Exoenzymes

12

__________ is the biggest organism in the world.

Fungus

13

Filamentous cells:

Hyphae

14

Two categories of hyphae are:

Septate and Coenocytic

15

This category of hyphae are fungal cells separated by porous septum. Pores allow exchange of small molecules. (E.g. Ribosomes, mitochondria, nuclei).

Septate

16

This category of hyphae lacks septa and has continuous cytoplasmic mass.

Coenocytic

17

Multicellular fungi that is a mass of hyphae. It's the main body of fungi and persists mostly underground.

Mycelium

18

Multicellular fungi that is specialized hyphae that form symbiosis with: host and exchanges or extracts nutrients.

Haustoria

19

A host with exchanges is a __________ relationship.

Mutualistic

20

Type of relationship where one organism extracts nutrients from another.

Parasitic

21

Mutualistic haustoria associated with plant roots; improves water and nutrient uptake.

Mycorrhizae

22

__________ facilitated plant movement on to land.

Mycorrhizae

23

Parasitic haustoria associated with nematodes.

Fungus trap

24

Collective hyphae

Mycelium

25

Fungi produce spores through __________ or __________ life cycles.

Sexual or asexual

26

In the __________ phase of fungal reproduction, haploid mycelium produces haploid spores, which may be contained in a sporangium.

Asexual

27

Step 1 in the sexual phase of fungal reproduction: haploid mycelium produce __________.

Pheromones

28

__________ signal for potential partners.

Pheromones

29

Step 2 in the sexual phase of fungal reproduction: mycelia exhibit movement towards a __________ __________ of different 'mating types' (similar to different sexes).

Pheromone source

30

Step 3 in the sexual phase of fungal reproduction: __________ __________.

Mycelia join
