Unit 2 - Cells and Organelles 2

Question 1

In the RER proteins are..

Answer 1

folded and processed, being modified in ways such as having sugar chains added.

Question 2

Proteins are transported from the RER to the…

Answer 2

Golgi apparatus in vesicles.

Question 3

At the Golgi apparatus the proteins…

Answer 3

undergo further processing where sugar chains are trimmed or more are added.

Question 4

Proteins are transported in/out/around cells in…

Answer 4

vesicles.

Question 5

Secretory cells, which release hormones or enzymes, have more…

Answer 5

rough endoplasmic reticulum than cells that do not release proteins.

Question 6

Proteins may be stored…(in which organelle?)

Answer 6

in the rough endoplasmic reticulum until they are needed by the Golgi apparatus

Question 7

Vacuole

Answer 7

Membrane lined sac in plant cells containing cell sap. Large permanent vacuoles as used to maintain turgor. The membrane of the vacuole is called the tonoplast. It is selectively permeable. if vacuoles appear in animal cells they are small and transient.

Question 8

What is the plasmodesmata

Answer 8

small channels that directly connect the cytoplasm of neighboring plant cells to each other, establishing living bridges between cells.

Question 9

Gram staining

Answer 9

All bacteria - positive or negative
Gram positive = purple
Gram negative = pink

Question 10

Where is dna found

Answer 10

Nucleus

Question 11

Where is RNA found

Answer 11

Nucleolus

Question 12

You can’t just say vacuole anymore, when talking about the differences between plant and animal cells. What must you say

Answer 12

Large, permanent vacuole

Question 13

How can you tell the difference between
Gogol body and ER in a diagram

Answer 13

Golgi body does not touch
