Flashcards in Pre-reqs prokaryote notes Deck (12):
1

(present on some prokaryotes) - structures protruding from the cell membrane that help the cell move.

Flagella

2

rigid structure outside the plasma membrane that surrounds, supports, and protects the cell. Found in most prokaryotes.

Cell wall

3

particles where proteins are synthesized (translation).

Ribosomes

4

lipid bilayer structure that separates cell from outside environment AND regulates what can enter/exit the cell.

Plasma (cell) membrane

5

jellylike substance contained by the cell membrane where most chemical reactions take place.

Cytosol

6

region where DNA is located.

Nucleoid region

7

appendages protruding from the capsule that help the cell adhere to surfaces.

Pili

8

protective layer outside the cell wall that helps some prokaryotes evade the immune system of their host

Capsule

9

Endosymbiont Theory?

Mitochondria & Chloroplasts are derived from bacteria

10

Chloroplasts developed from ancient?

photosynthetic bacteria

11

Mitochondria developed from ancient?

aerobic purple bacteria

12

3 steps of endosymbiont theory?

(1) ancient eukaryotic cell engulfs ancient purple bacteria
(2)Later, a cell with resident purple bacteria engulfs ancient photosynthetic bacteria
(3)eventually develop into modern plant cells and certain protists
