Active transport is the final method of how particles move that you need to know.
Surprise, surprise, you should be familiar with your this text-book definition.

Osmosis
The movement of particles is a vital process and happens in various ways. Osmosis is similar to diffusion but has a couple of differences.
Again you should try to remember this text-book definition.
Diffusion
Diffusion is one of the key concepts you need to learn for GCSE. With diffusion you will know why if some sprays some deodorant or perfume in one corner of the room why it spreads everywhere else.
You will need to know this text-book definition.
Mitosis
Cell division is an important function for example growth and repair. We call this process mitosis.
You need to know what happens during this process including how the amount of DNA changes.
DNA and Chromosomes
Inside your cells, specifically the nucleus, contains all the genetic information, DNA, that makes us the way that we are. We get our DNA from out parents, half from mum and half from dad, and they are stored in tightly coiled bunches called chromosomes.
Humans have 23 pairs of chromosomes, 46 in total, 23 from each parent. The information on these chromosomes gives us our hair colour, eye colour, skin colour etc …
Stem Cells
After looking at specialised cells you should know that not all the cells are the same, but where do they come from? How are they made?
Stem Cells are responsible for creating these specialised cells.
Differentiated Cells
You should have looked at the typical structures of plant and animal cells. The human body is made up of a couple of hundred different types of cells. You will need to give examples of specialised cells (differentiated cells), cells adapted for a specific job.
Below shows different specialised cells and their basic adaptations.
Eukaryotes vs Prokaryotes
You will need to know the differences and similarities between Eukaryotes and Prokaryotes.
The table below will help you.
Eukaryotes
Examples of eukaryotes are animal and plant cells. You will need to know what they look like and be able to compare them to a typical prokaryote, a bacteria cell.
Prokaryotes
Prokaryotes are much simpler than eukaryotes, animal and plant cells. You will need to know the parts and functions of a typical prokaryote.
Our example is a bacteria cell
