Protists Flashcards
1
Q
Eukaryotic structure
A
Membrane bound organelles
- Cytoskeleton: Microtubules, Microfilaments, Intermediate filaments.
2
Q
Microtubules
A
- Made from tublin proteins
- Key to eukaryotic flagella and cilia movement
Dynein motor proteins- cause binding
3
Q
Microfilaments
A
- Made with actin proteins
Myosin motor protein- produce cell movement
4
Q
Photoautotrophs
A
- Contains chloroplasts, and does secondary endocytosis
- Makes their own energy using light from the sun.
5
Q
Chemoheterotrophs
A
- An organism that gets energy from the oxidation of inorganic compounds.
- Absorptive
- Ingestive
6
Q
Origin
A
- Heterotrophic prokaryote gained a nucleus
- mitochondria gained by endosymbiosis
- Cyanobacteria joined (chloroplast)
- Plastids from eukaryotic, symbiotic algae through 2nd endosymbiosis.
7
Q
Eukaryotes
A
- Unicellular
- Colonial, daughter cells remain connected
- Multicellular, cell specialization, cell junctions
- Multinucleate
8
Q
Reproduction
A
- Asexual, mitosis (2n/n cells)
Asexual budding, fragmentation (sponges) - Sexual reproduction, meiosis and fertilization
Separate haploid and diploid phases.
