cell structure

Question 1

Functions of the cellular membrane?

Answer 1

1. Transport (selectively permeable)
2. cell recognition (carb identity tags)
3. communication (proteins allow cells to talk to each other)
4. Homeostasis- maintaining optimal conditions

Question 2

structure of the cell membrane?

Answer 2

phospholipid bilayer

Question 3

Functions of the nucleus
(middle of cell contains nucleolus)

Answer 3

1. control center
2. nucleolus makes ribosomal rna (rRNA)

Question 4

structure of nucleus?

Answer 4

Nuclear envelope, nuclear pore

Question 5

functions of the endoplasmic reticulum

Answer 5

rough ER (ribosomes attached) - protein synthesis
smooth ER - lipid synthesis
transportation

Question 6

structure of endoplasmic reticulum?

Answer 6

membrane channels

Question 7

functions of ribosomes?

Answer 7

site for protein synthesis

Question 8

functions of golgi apparatus ?

Answer 8

modifies, assembles, packages and stores, and secretes substances (proteins)

Question 9

Functions of Lysosomes?

Answer 9

cellular digestion, auto digestions or breakdown of a whole cell. “ Apoptosis”

Question 10

Structure of lysosomes?

Answer 10

membrane sac with hydrolytic enzymes = hydrolysis

Question 11

vacuole/ vesicle

Answer 11

vacuole (storage) in plants and transport (vesicle)

Question 12
