Name some features of a plant
They are multicellular
They have chloroplasts which means they can photosynthesise
Their cells have cell walls, which are made of cellulose
Plants store carbohydrates as sucrose or starch
Name some features of animals
Are multicellular
They can not photosynthesise as they don’t have chloroplasts
They often store carbohydrates in the form of glycogen
Name some features of fungi
Some are single celled
They can not photosynthesise
Most feed by saprotrophic nutrition
Name some features of protoctists
Single celled and microscopic
Similar to plant cells
Others are more like animal cells
Name some features of bacteria
Do not have a nucleus
Some can photosynthesise
Most bacteria feed off other organisms
Name some features of a virus
An example of a parasite
Infect all types of living organisms
Do not have a cellular structure
What is a pathogen
Organisms that cause disease including fungi, protoctists and bacteria
What is an enzyme
Catalysts produced by living things
How can you make a reaction quicker
By raising the temperature
What is a substrate
A molecule that is changed in a reaction
What is an active site
Where a substrate joins onto the enzyme
What is a denatured enzyme
When the substrate no longer fits into the active site
What is the optimum pH for most enzymes
PH of 7
Why is diffusion important in living organisms
It’s how a lot of substances get in and out of the cells
What is diffusion
The net movement of particles from an area of high concentration to an area of low concentration
