Unicellular organisms
Organisms made up of only one cell
Multicellular organisms
Organisms made up of many cells (2 or more)
Organelles
Organs inside the cell that have a specific job or function
Nucleus
An organelle that controls all activities of the cell
Is the control centre of cell
Cell membrane
In both plants and animal cells
The skin that holds everything together
Cell wall
Only in plant cells
Gives cell structure to keep plant upright. Works as the Skeleton of the plant
Cytoplasm
Watery, jelly like substance that contains many smaller parts
Vacuole
In animal cells it contains the chemicals and waste
In plant cells contains nutrients, waste, water and sap
Chloroplast
In plant cells and only in green parts of plants
Contains chlorophyll and is the site for photosynthesis
Fungal cells
Same organelles as an animal cell plus a cell wall
Cell wall is made up of different material than plants
How are plant cells different than animal cells
Plant cells have a cell wall and chloroplasts
Do fungal cells have chloroplast
No, therefore they cannot make their own food
They create there own food by digesting material they are growing on
Mitosis
Cell division that produces two identical cells
Uni and multicellular mitosis
Uni- mitosis used for reproduction
Multi- mitosis used for repair and growth
Bacteria
Example of unicellular organism
From monera kingdom
Some bacteria causes disease and infection while some help you stay healthy
What doesn’t a unicellular organism have
A nucleus or any organelles
Cell theory
All living things are made up of one or more cells
Cells are the basic building blocks for all living things
New cells are produced from existing cells
Mitochondria
The powerhouse of the cell that releases energy from food
