|
Prokaryotic vs. Eukaryotic cells
|
Pro do not have nucleus, both have plasma membranes, pro does not have membrane-bound organelles
|
|
|
Parts of an animal cell (13)
|
plasma membrane, cytoskeleton, peroxisomes, mitchondria, lysosome, golgi, ribosomes, nuclear envelope, nucleolus, chromatin, smooth er, rough er, centrosome
|
|
|
Parts of a plant cell (15)
|
cell wall, plasma membrane, plasmodesmata, chloroplast, cytoskeleton, central vacuole, mitochondria, ribosomes, smooth er, rough er, nuclear envelope, nuclear membrane, nucleus, golgi, peroxisome
|
|
|
microtubules
|
biggest, hollow tubes, tubulin, used to maintain cell shape, movement (cilia/flagella), chromosome movement and organelle movement
|
|
|
microfilaments
|
made of actin, smallest, coiled, maintains shape, changes in shape, muscle contractions, cytoplasmic streaming, movement, cell diviion
|
|
|
intermediate filaments
|
middle size, made of fibrous proteins called keratins. Maintain cell shape, anchor nucleus to organelles, forms nuclear lamina
|
|
|
Tight junctions
|
prevent fluid from moving across layer of cells
|
|
|
Gap junctions
|
connects plasma membranes of adjacent cells, tube like
|
|
|
Desmosomes
|
made of intermediate filaments
|
|
|
amphipathic membrane
|
hydrophilic head, hydrophobic tail
|
|
|
How does a protein get from the ER to outside the membrane?
|
ER sends vesicle of transmembrane glycoproteins to the golgi. Fuses with golgi and picks up other things, like glycolipids. Vesicle is sent out to cytoplasm and fuses with membrane. Cell pushes the vesicle's contents out and the membrane elongates
|
|
|
Plants and animals in hyptonic solution
|
plant- turgid (normal)
animal- bursts |
|
|
Plants and animals in isotonic solution
|
Plant- flaccid (shrivel)
Animal- normal |
|
|
Plants and animals in hypertonic solution
|
plant- plasmolyzed
animal-shrivels |
|
|
Arrange from biggest to smallest: prokaryotic cell, virus, eukaryotic cell, nucleus
|
euk, nucleus, pro, virus
