Q

how is a plant cell different from animal cell

A

they have cell wall, chloroplasts, and a large vacuule(big space in the middle)
animals only have cell membrane and small vacuole

Q

what the cell membrane structure layers

A

bilipid layer

15
Q

what is the membrane cell layer made of

A

phospholipid

16
Q

what is the head end and tail end of the phospholipid

A

head is hydrophilic
tail is hydrophobic

17
Q

is the head or the tail inside the lipid bilayer

A

the hydrophobic tail

17
Q

where do things come out of in the membrane

A

the proteins

18
Q

what are the nametage cells that say this cell belongs to me

A

carbohydrates

19
Q

what are carbs mostly on

A

proteins and lipids(mostly proteins)

20
Q

what info is on inside of nucleas

A

dna(in form of chromatin)

20
Q

whats the dark structure in the nucleus

A

nucleolus

21
Q

what is the nucleolus make

A

RNA

22
Q

cytoskeleton

A

l. The cytoskeleton’s main function is structure and support for the cell,

23
Q

whats the difference between microtubule and microfilaments

A

microtuble is hollow in the middle and a little larger and its like a zipline
microfilaments hold things in place structure

24
Q

what are the storage containers in the cell

A

vacuoles

25
Q

what is chloroplast

A

the organelle that is responsible for photosythesis

26
Q

what is cytooplasm

A

Material inside the cell membrane–not including the nucleus

27
Q

what is a vacuole

A

membrane bound organelles that can be found in both animals and plants

28
Q

what is a ribosome

A

Material inside the cell membrane–not including the nucleus

29
Q

vesicle

A

A small sac formed by a membrane and filled with liquid.

30
Q

lysosome

A

breaks down and recycles cellular components,

31
Q

where do ribosomes hang out

A

in the endoplasmic reticulum

31
Q

when ribosomes are attached to endoplasmic reticulum its called…

A

rough er

32
Q

what are all the foldings

A

primary secondary tertiary and quantenery foldings

33
Q

where does the vesicle move to after being formed or whatever

A

the golgi appartus

34
Q

say all the steps of the thing

A
  1. proteins are assembled or ribosomes
  2. proteins targeted for export to the cell membrane or to specialized locations within the cell complete their assemblies on ribosomes bound to the rough er
    3.newly assembled proteins are carried from the rough endoplasmic reticulum to the Golgi apparatus in vesicles
    4.the Golgi apparatusd further modifies proteins before sorting and packaging them in membrane-bound vesicles
  3. vesicles from the Golgi apparatus are shipped to their final destination in or out of the cell.
