Answers

Question 1

  • Cells are the fundamental unit of life
  • All organisms are made up of one or more cells
  • All cells come from pre-existing cells

 

Question 2

Eukaryotes

  • DNA is stored in the nucleus.
  • Have membrane-bound organelles.
  • No cell wall (except in plants, fungi and some protists).

Prokaryotes

  • DNA is free-floating in the cytoplasm.
  • No membrane-bound organelles.
  • Have a cell wall.

 

Question 3

The inner mitochondrial membrane has many folds called cristae that increase its surface area while maintaining a relatively small volume.

As cellular respiration reactions occur on the inner membrane, high surface area maximises the rate of cellular respiration to efficiently produce ATP and meet the energy demand of the cell.

 

Question 4

False

 

Question 5

Plants are autotrophs that make their own food through the process of photosynthesis.

Photosynthesis is a two-step process:

  1. The light-dependent stage which requires sunlight and occurs in the thylakoid membrane and the light-independent stage which does not require sunlight and takes place in the stroma fluid of the chloroplast.
  2. Photosynthesis converts water and carbon dioxide into oxygen and glucose which is used as a source of energy.

 

Question 6

A = Substrates

B = Enzyme

C = Product

 

Question 7

  • Aerobic respiration requires oxygen, but anaerobic respiration does not.
  • Aerobic respiration can produce up to 36 ATP from one glucose molecule, but anaerobic respiration produces only 2.
  • Aerobic respiration is completed within the mitochondria, but anaerobic respiration is not.

 

Question 8

True

 

Question 9

(a) Transmission electron microscopy

 

Question 10

False
