Transcript Unicellular Adaptations Powerpoint

Slide 1

Unicellular Adaptations-

1.2.3
 Explain how specific cell adaptations help cells survive

in particular environments (focus on unicellular
organisms).

Bacteria vs. Protists
 Bacteria
 All unicellular
 All prokaryotic- no nucleus
or membrane bound
organelles

 Protists
 Unicellular; some
multicellular
 ALL eukaryotic- have a
nucleus and membrane
bound organelles

Diversity of Protist Kingdom

Protozoa-Algae-and-Funguslike-protists

Various Structures
 Contractile vacuole-

regulates osmosis so a cell
does not gain to much
water.
 Found in many protists:

amoeba, paramecia,
euglena

Various Structures
 Cilia- hair-like

projections (some
protists).
 Flagella- tail-like
projections (some
bacteria and protists).
 Both used for

locomotion
(movement).

Various Structures
 Pseudopods- extensions of

the cytoplasm used for
movement and feeding
(amoebas).
 Eyespots- detect changes in
light (dinoflagellates and
euglena).

Adaptive Behaviors
 Chemotaxis- movement towards or away from

chemicals.
 E. Coli swims towards amino acids and sugars.

 Phototaxis- movement towards light.
 Euglena and Cyanobacteria swims towards light to
photosynthesize.

 Seen in some bacteria and protists.
