What are organelles? 
They are tiny structures within cells.
What are some organelles found in a typical animal cell? 
- Nucleus
- Cell membrane
- Cytoplasm
- Mitochondria
- Ribosomes
What is the nucleus? 
An organelle, which contains the genetic material that controls the cells activities. It is surrounded by its own membrane.
What is the cell membrane?
This membrane forms the outer surface of the cell and controls the substances that go in and out
What is cytoplasm? 
A gel like substance, when most of the cells chemical reactions happen, it contains enzymes which control these reactions
What is the mitochondria? 
Small organelles where most of the reactions for aerobic respiration take place, respiration transfers energy that the cells need to work
What is the ribosome? 
Small organelles were proteins are made in the cell
What extra organises a typical plant cell have? 
- Chloroplasts
- Cell wall
- Vacuole
What are chloroplast? 
Photosynthesis, which makes food for the plant happen here. Chloroplasts contain, green substance called chlorophyll, which is used in photosynthesis
What is a cell wall?
Rigid structure made of cellulose, which surrounds cell membrane, it supports the cell and strengthens it
What is vacuole? 
A large organise that contains cell sap, (a weak solution of sugars and salts). It helps to support the cell.
What are cells either? 
Eukaryotic or prokaryotic
What are eukaryotic cells?
They are complex cells and include all animal and plant cells
What are prokaryotic cells?
They are smallest and simpler cells, for example bacteria
What is a tissue?
A group of cells that act together to perform a specific function.
Tissues can contain 
More then 1 types of cell
What's an organ? 
A group of different tissues that work together to perform a function
Organs can be made up of ___
Different tissue types
What is a group of organs working together called?
An organ system
