Homework….

Find a diagram of a plant and animal cell (textbook or internet).

Redraw both cells and label them fully.

Research the difference between a prokaryote and eukaryote cell. Put your info into a suitable table.

Title: Cells…

Lesson Objectives:

1. Can I name and identify cell organelles? Grade C

2. Can I compare and contrast prokaryotic and eukaryotic cells? Grade B/A

Starter: Study your pics of cells….then label mine…

The type of cell you are currently familiar with:

Cell theory….The basic principles of the cell theory are:

All organisms are made of cells that resemble each other by having internal structures and a boundary

These cells are always formed by the division of pre-existing cells

Cells contain inherited information which determines their activity

Given suitable conditions, cells are capable of independent existence

Can you name the 7 characteristics all living things share?

Cell Structure… Given these principles of cells, biologists

recognise two types of cellular structure:Prokaryotic cells (‘before the nucleus’)Eukaryotic cells (‘with a nucleus’)

Virus particles do not fulfil the criteria of the cell theory and so are regarded as being non-cellular. Some texts may refer to their structure as being ‘akaryotic’ (without a nucleus)
