Lesson Aim: Know the organisation of the human body

Todays objectives:

LO1 Recall previous knowledge on cells

LO2 Determine the structure and function of organelles

LO3 Create an animal cell

Introduction to a generalised animal cellTask 3 minutes.

Research a definition of an animal cell

The basic membrane-bound unit that contains the fundamental molecules of life and which all living things are made of.

Cells forms the basic units of all living organisms. Cells show properties that characterise life. They absorb or produce food, reproduce, are sensitive to changes in their environment and control their chemical processes. There are lots of different types of cells that make up living organisms but they are all similar in structure. www.britannica.com accessed 09/09/16

All Cells need to be able to perform these functions to be able to survive and reproduce.

What do you already know?Individually, write down everything you know or can remember about cells.

If you need pointers think about the following questions:

What do cells make?Are there different types of cells?What is inside a cell?

Nucleus this is in the centre of the cell and controls all of the cells activityCell Membrane this protects the cell and helps to maintain its shape by surrounding all of the organellesMitochondria this organelle provides the cells energy and looks like a woodlouse!Nucleolus this organelle is in the centre of the nucleus and contains each cells genetic material.

Cytoplasm this is the fluid that suspends all of the organelles, it nourishes the cellGolgi Complex this organelle creates proteins which cell needs to grow and reproduce. It looks like a stack of rubber bands. Endoplasmic Reticulum this organelle surrounds the nucleusLysosome this organelle acts as a cell cleaner and metabolises worn out organelles. It looks like a passion fruit in this pictureVacuole this organelle looks is comparative to a bubble and acts as a storage unit for the cell.
