Flashcards in chapter 12 Deck (23):
1

what are some characteristics of Protozoa

Eukaryotic
unicellular
classified by motility
some parasitic

2

what are habitat of Protozoa

require moisture
live in water and soil
can live in extreme environments

3

what's the nutrition of Protozoa?

feed on plant and animal debris
absorb food through CELL MEMBRANE
vacuoles --> digestion
heterotrophic

4

what is heterotrophic

have to get food from the outside of body

5

what are the stages of Protozoa?

trophozoite and cysts

6

what is the trophozoite phase?

moitle, feeding stage
requires water and food

7

what is the cyst stage?

dormant stage --> when conditions are unfavorable
*Protozoa can flip between stages

8

Can Protozoa reproduce sexually or asexually or both?

both
asexual --> binary fission, budding, and schizogony
sexually --> conjugation

9

What is binary fission?

one cell divides into two new cells

10

what is budding?

protrusion off of parent cell

11

what is schizogony?

nucleus undergoes multiple divisions before cell divides

12

what is conjugation?

genetic exchange between 2 mating pairs that require CELL TO CELL CONTACT

13

What is classification of a Protozoa?

D: Eukarya
K: Protista
Sub-K: Protista

14

What are the characteristics of Algae?

Eukaryotic
Unicellular or multicellular
classified by pigment
contain cloroplasts
photoautotrophic

15

what does photoautotrophic?

use light to make food.

16

what are the stucutes of algae needed to know?

thallus --> body
holdfast --> root
stripe --> stem
blade --> leaf

17

what is the habitat of Algae

aquatic environment --> soil and rocks
cool water often near surface

18

do Algae reproduce asexually or sexually?

both but mostly asexually by binary fission

19

how do you classify Algae?

D: Eukarya

what are the uses of fungi?

food chain
mushroom for food
bread beer and wine
drugs
anticancer drugs
