Q

Name all the main parts of an Animal Cell

A
  • cell membrane
  • ribosomes
  • Mitochondria
  • nucleus
  • cytoplasm
18
Q

What is the function of cytoplasm in an animal cell

A

It is the site of chemical reactions in the cell

19
Q

What is the function of the cell membrane

A

It controls the entry and exit of of substances

20
Q

What is the function of the nucleus

A

It controls the activities of the cell, and holds the DNA

21
Q

What is the function of the mitochondria

A

To release energy through respiration (a chemical reaction)

22
Q

What is the function of ribosomes

A

To make proteins (protein synthesis)

23
Q

What is the function of ribosomes

A

To make proteins (protein synthesis)

24
Q

Label a plant cell diagram

A

25
Q

Name all the main parts of a plant cell

A
  • cytoplasm
  • nucleus
  • cell membrane
  • cell wall
  • mitochondria
  • permanent vacuole
  • chloroplasts
26
Q

What is the function of the permanent vacuole

A

Contains cell sap which has dissolved sugar, mineral ions and other solutes. The permanent vacuole shapes the cell.

27
Q

What is the function of chloroplasts

A

Chloroplasts are where photosynthesis occurs. Chloroplasts contain chlorophyll.

28
Q

What is the function of a cell wall

A

To provide structure and protection for the cell

29
Q

Label a fungi cell diagram

A

GO TO GOODNOTES

30
Q

How do fungi get nutrition

A

Saprotrophic nutrition - fungi secrete enzymes onto their food, and the enzymes break down the food into molecules, which the fungi absorb.

Q

Function of the fine focusing wheel

A

O sharpen focus, at a higher magnification

38
Q

Function of the objective lens

A

Selectable lenses that magnify the object

39
Q

Function of the base

A

To keep the microscope stable

40
Q

Function of the stage

A

The platform to place the glass slide on

41
Q

Function of the diaphragm and condenser

A

To focus light on the part of the slide being studied

42
Q

Equation for magnification

A

Magnification = image size / actual size
