CH5 Flashcards
1
Q
similarities/differences between fungal and protozoan cells
A
- similarities: ribosomes, mitochondria, ER, nucleus, cell membrane, golgi, storage vesicle, centrioles
- differences: cell wall, budding scars and nucleolus in fungal cells and flagella, pellicle and capsule in protozoan
2
Q
how to fungal cells reproduce?
A
- by budding
- bud out daughter yeasts
- after each budding, they scar and die once they have too much scarring
3
Q
describe the endosymbiotic theory and what arose from it
A
-evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms
4
Q
describe mitochondria and chloroplasts in the endosymbiotic theory
A
- early eukaryotic cell ingested gram - bacterium that can do aerobic respiration
- instead of killing the bacterium, the host cell kept it
- mitochondria originated from endosymbiotic alpha- proteobacteria
-chloroplasts originated from endosymbiotic cyanobacteria
- animals, fungi and protists have mitochondria
- plants and algae have mitochondria and chloroplasts
5
Q
how are mitochondria and chloroplasts similar to bacterial cells
A
size, DNA (single circular chromosome), 70s ribosomes, divide by binary fission
