cells and organelles basics

Question 1

features of Eukaryotic cell

Answer 1

nucleolus, cell membrane, nucleus, vacuole, endoplasmic reticulum which is where the moving of protein happens, ribosomes site of protein produced, lysosomes waste, golgi apparatus exports and packages protein, mitchondria energy, cytosol

Question 1

features of a prokaryote cell

Answer 1

cell wall, pilus, ribosomes, flagellum the tail, cytosol inside liquid, dna plasmid is sticky circle, and dna

Question 2

what is a cell membrane and what does it do?

Answer 2

plasma membrane surronds all cells

forms a barrier select what goes in or out, selectively permable

Question 3

function of plasma membrane

Answer 3

controls movement
creates confined areas for functions
restricts movement of substances
recognition and communication between cells

Question 4

plant vs animal cell

Answer 4

plant: cell wall giving rigid shape, central permanent vacuole, chloroplasts which is an oval with stripes,

Animal: centrosomes circle with lines coming out of it, lysosome is a circle with dots, golgi apparatus looks like wifi, smooth endoplasmic reticulum, looks like streaks of lines.

Question 5

what is plasmolised

Answer 5

cell loses water when placed in a hypotonic solution, only in plants

Question 6

what is crenation

Answer 6

shrinking of cell due to water loss, in hypotonic animal cell

Question 7

cytolysis

Answer 7

bursting of cell due to water movement, hypotonic animal cells
