Module 1- Cells as the Basis of Life

Question 1

Cells as the basis of life

Answer 1

Cell structure
Cell function

Question 2

What distinguishes one cell from another?

Answer 2

Different cellular structure
- variety of prokayotic and eukaryotic cells
- range of technologies used to determine cell structure and function
Variety of prokaryotic and eukaryotic cell structures
- drawing scaled diagrams of a variety of cells
- comparing and contrasting different cell organelles and arrangements
- modelling the structure and function of the fluid mosaic model of the cell membrane

Question 3

How do cells coordinate activities within their internal environment and the external environment?

Answer 3

Way in which materials can move into and out of cells
- modelling diffusion and osmosis
- roles of active transport, endocytes and exocytosis
- relating the exchange of materials across membranes to the surface-area-to-volume ratio, concentration gradients and characteristics of the materials being exchanged
Cell requirements
- suitable forms of energy, including light energy and chemical energy in complex molecules
- matter, including gases, simple nutrients and ions
- removal of wastes
Biochemical processes of photosynthesis, cell respiration and the removal of cellular products and wastes in eukaryotic cells
Model the action of enzymes in cells
The effects of the environment on enzyme activity through the collection of primary or secondary data
