Cell Structure

Question 1

What is found on the surface of the cell and is surrounded by a membrane which has pairs of microtubules inside?

Answer 1

Flagellum

Question 2

Difference between role of RER and Golgi apparatus

Answer 2

RER folds and processes proteins whereas the gage apparatus packages for transport

Question 3

Why use specific stains (2)

Answer 3

Stain X stains the Y so it can be seen against a background. (1) it allows differentiation between a and b (2)

Question 4

How to use a microscope (4)

Answer 4

1) Lowest powered objective lens. 2) Use coarse adjustment knob to set stage just below objective lens. 3) Coarse adjustment knob until image is roughly in focus. 4) Fine adjustment knob until there is a clear image

Question 5

Common similarities between species and bacteria

Answer 5

Both have cell membrane

Question 6

When comparing differences you must?

Answer 6

State that A has A feature whereas B has B feature

Question 7

ATP is not produced but? It is not necessary but?

Answer 7

1) generated 2) required

Question 8

Which microscope?

Answer 8

X because H has X feature that others don’t. This is so we can see ….

Question 9

Microtubules are ….. for movement of flagella

Answer 9

Responsible. Necessary so it can reach egg to deliver genetic material

Question 10

Why do me not need to stain RBC

Answer 10

Have nucleus and are red

Question 11
