Flashcards in Chapter 16 Part 1 Deck (25):
0

A protist that produces its food by photosynthesis.

Alga/Algae

1

A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; a characteristic of plants and multicellular green algae.

Alternations of generations

2

A protist that moves and feeds by means of pseudopodia.

Amoeba

3

A member of a clade of protists that includes amoebas and slime molds and is characterized by lobe-shaped pseudopodia.

Amoebozoan

4

One of two prokaryotic domains of life.

Archae

5

An organism that makes its own food (often by photosynthesis), thereby sustaining itself without eating other organisms or their molecules. Plants, algae, and numerous bacteria are autotrophs.

Autotroph

6

A rod-shaped prokaryotic cell.

Bacillus

7

One of two prokaryotic domains of life.

Bacteria

8

A surface-coating colony of prokaryotes that engage in metabolic cooperation.

Biofilm

9

The use of living organisms to detoxify and restore polluted and degraded ecosystems.

Bioremediation

10

One of a group of marine, multicellular, autotrophic protists belonging to the stramenopile clade; the most common and largest type of seaweed. This organism includes the kelps.

Brown Algae

11

A type of protist that has unicellular amoeboid cells and aggregated reproductive bodies in its life cycle; members of amoebozoan clade.

Cellular Slime Mold

12

An organism that obtains both energy and carbon from inorganic chemicals. This organism makes its own organic compounds from CO2 without using light energy.

Chemo-autograph

13

A group of bacteria that live inside eukaryotic host cells. Includes human pathogens that cause blindness and nongonococcal urethritis, a common sexually transmitted disease.

Chlamydia

14

A type of protist that moves and feeds by means of cilia. This protist belongs to the alveolate clade.

Ciliate

15

A spherical prokaryotic cell.

Coccus

16

Photoautotrophic prokaryotes with plantlike, oxygen-generating photosynthesis

Cyanobacteria

17

A unicellular, autotrophic protist that belongs to the stramenopile clade. This mircroorganism possess a unique, glassy cell wall containing silica.

Diatom

18

A member of a group of protists belonging to the alveolate clade. These organisms are common components of marine and freshwater phytoplankton.

Dinoflagellate

19

A thick-coated, protective cell produced within a bacterial cell. This microorganism becomes dormant and is able to survive harsh environmental conditions.

Endospore

20

A poisonous component of the outer membrane of gram-negative bacteria that is released only when the bacteria die.

Endotoxin

21

A poisonous protein secreted by certain bacteria.

Exotoxin

22

A microorganism that lives in a highly saline environment, such as the Great Salt Lake or the Dead Sea.

Extreme Halophile

23

A microorganism that thrives in a hot environment (often 60-80°C).

Extreme Thermophile

24

A protist that moves and feeds by means of threadlike pseudopodia and has porous shells composed of calcium carbonate.

Foraminiferan
