Answer 1

Cell membrane - controls the movement of substances in and out of the cell
Mitochondria - generate and release energy
Cytoplasm - site of chemical reactions
Nucleus - controls activity of cell, where DNA is stored
Ribosomes - where proteins are made
Cell wall - gives cell structure
Chloroplast - site of photosynthesis
Vacuole - used for storage filled with cell sap

Question 2

Recall the relative size of bacterial cells (prokaryotic cells)

Answer 2

0.2 to 2 micrometers

Question 3

Describe the difference in how the genetic material is found within eukaryotic and prokaryotic cells.

Answer 3

Eukaryotic has a nucleus

Prokaryotic has a loop of DNA

Question 4

Explain how the structure of different types of cell relate to their function; Including sperm cells, nerve cells and muscle cells in animals and root hair cells, xylem and phloem cells in plants.

Answer 4

They are adapted to carry out their functions

Question 5

To be able to calculate magnification, image size and actual size

Answer 5

Image size
___________________________
Actual size x magnification

Question 6

To be able to convert between cm, mm, micrometers, and nanometers

Answer 6

Cm -> mm = x10
Mm -> um = x1000
Um -> nm = x1000
