Draw a cell

Last lesson you learned about cells and their parts.

Use your memory to make a drawing of a simple cell.

Try to name as many parts in your drawing as possible.

Tips:

• Start with the shape of the cell and its outside, (what is this part called?)
• What different parts are inside the cell? Go one by one.
• If you can't remember the shapes, start by writing the names of parts you can remember
• Is your cell a plant, animal, etc.? Are there any special parts for this type of cell?

What is the definition of:
Organ

Plant organs

Molecules: Tiny parts of a substance. 

For example a drop of water is made of millions of water molecules.

Other examples are: Oxygen and carbon dioxide.

Organelles: the 'organs' or parts of a cell.

They perform different functions for the cell.

Cells: the smallest living part of organisms.

These take many different forms and shapes

Tissue:, a group a same-type cells.

You can find many different tissue types in an organism

Organ: a group of tissues that together perform a specific task

Organ system: a group of organs that work together to perform a function

Organism: all of the other parts combined form the organism, a living being.

Levels of organisation

Each level is a combination of the levels beneath it.

For example: Many cells together form a tissue

Level	Description	Example
Organism	1 Living being	a deer
Population	Group of organisms of the same species	all deer in a forest
Community	All organisms that live together in a specific place.	all deer, insects, birds, plants, etc. that live in a forest
Ecosystem	A community + all non-living parts: like the ground, water	everything found in a forest
Biosphere	Part of the planet where life is possible	most parts of planet earth
Planet	Everything that is part of the planet	earth
