It is the basic building blocks of all living organisms
1 of 15
What are the two ways Organisms are categorised?
Eukaryotes and Prokaryotes
2 of 15
Compare Eukaryotic cells & Prokaryotic cells
Eukaryotic Cells are complex and relatively large and includes Animal and Plant Cells in contrast to Prokaryotic cells which are smaller and simpler ( single-celled organism)
3 of 15
What are the size range of eukaryotic cells?
10-100 micrometres in size
4 of 15
What are the Similarities and Differences between Animal and Plant cells
why does Plant cells have 3 more sub-cellular structures
Plant have to make their own food and stay in the same place

Describe Bacteria Cells
1. Prokaryotes 2. Don't have a 'true' nucleus instead a single circular strand of DNA that floats freely in the cytoplasm 3. May contain 1 or more small rings of DNA called plasmids 4. No Chloroplasts or Mitochondria
7 of 15
Identify extra details of a bacteria cell
1. The Circular Strand of DNA is not in a chromosome
8 of 15
What is binary fission?
The bacteria will copy everything inside the circular strand before dividing (making another copy) and will split down in the middle
9 of 15
Give one disadvantage of Plasmid
They don't have full set of instruction to make a new bacterial cell, however they can be passed on easily to one another bacteria cell & cross species. Often bacteria exchange genes that confer resistance to antibiotics.
10 of 15
Give one advantage of Plasmid
Open up the bacterial cell using enzymes and put in a gene from a different specie i.e. human to make insulin, this could be genetically engineered and the bacterial cell can produce medicines
11 of 15
What is the adaptation of bacteria that lives in water?
They have something called 'flagellum'(s) which is like a tail that enables them to swim in water
12 of 15
What is the adaptation of bacteria that lives in the air?
'Slime capsule' it is a slimy & mucous based layer that prevents them from drying n found i.e. on skin/devices etc
13 of 15
What are the size ranges of prokaryotic cells?
1-10 micrometres
14 of 15
What is that one thing all cells have in common?
They all have sub cellular structures
