Where is the genetic material found in:
a) animal cells
b) bacterial cells
a) nucleus
b) single strand of DNA

What type of organisms are bacteria - prokaryotes or eukaryotes?
Prokaryotes
4 of 16
What gives a higher resolution, a light microscope or an electron microscope?
Electron Microscope

What is cell differentiation?
Differentiation is the process which a cell changes to become specialised for its job.

Give three ways a sperm cell is adapted for swimming to an egg cell.
A long tail, a streamlined head and lots of mitochondria to provide energy.
7 of 16
What are chromosomes?
Chromosomes are coiled up lengths of DNA molecules that contain genetic information.
8 of 16
What is the cell cycle?
The cell cycle makes new cells for growth, development and repair.

What is mitosis used for by multicellular
organisms?
Multicellular organisms use mitosis to grow or replace cells that have been damaged.

Give two ways that embryonic stem cells could be used to cure diseases.
They could be used to replace faulty cells, make insulin producing cells for people with diabetes and nerve cells for people paralysed by spinal injuries.

Why might someone be opposed to the use of human embryos in stem cell research?
Some people are against stem cell research as they feel that human embryos shouldn't be used in experiments since each one is a potential human life.

What is diffusion?
Diffusion is the spreading out of particles from a area of higher concentration to an area of lower concentration.
13 of 16
Name three substances that can diffuse through cell membranes and two that can't.
Can- Glucose, amino acids and water
Can't- starch and proteins
14 of 16
What type of molecules move by osmosis?
Water molecules
15 of 16
Give the two main differences of active transport and diffusion.
The primary difference between active transport and diffusion is that active transport needs cellular energy to transport the molecules against the concentration gradient. In contrast, diffusion refers to the passive transport method where the molecules
