1. Unit 5 Anatomy and Physiology
Cells

2. To identify the component parts of a cell.
Aim: To introduce the fundamentals of anatomy and physiology and cell function.
Objectives:
To identify the component parts of a cell.
To describe the functions of the main cell components.

3. The human body is made up of:
Cells
Tissues
Organs
Systems

4. What is a cell? The “building block” of all living things.
All living things made up of 1 or more cells
Organised in groups each of which have specific functions

5. Cells - the facts The human body is made up of millions of tiny cells
These can only be seen under a microscope
They appear in many different shapes and sizes and have different functions
Each cell has a nucleus which contains the genetic coding called DNA
Cells cannot function by themselves
The Function of Cells Video

6. Practice Quiz
Individually complete the practice quiz sheet. After you have completed the quiz you need to score your sheet. Score 2 points for every correct answer.

7. Cells
Cell Organelles
Watch the video and take some notes, you will need this information later!!!!
Now have a go at labelling the diagram with the right parts

8. A Human Cell

10. What do they all do?
Complete the table with the answers that you think are correct.

11. What is? DNA The chemical containing the genetic code CHROMOSOME
A thread shaped body consisting of DNA

12. Nucleus The largest organelle.
Cell survival and reproduction happens here
Contains DNA, the chromosomes and proteins and the chromatin

13. Nuclear Envelope
a physical barrier (membrane) separating the contents of the nucleus from the surrounding cytoplasm

14. Endoplasmic reticulum
is concerned with the manufacture and transportation of materials in the cell.
Rough ER - are important in the production and transportation of proteins.
Smooth - creates and stores steroids

15. Ribosomes
Produce the protein in a cell.

16. Cytoplasm This is the fluid that fills the cell.
The cells organelles are suspended in the cytoplasm.

17. Mitochondria Mitochondria are know as the powerhouses of the cell.
They take in nutrients, break them down and creates energy for the cell
This process is known as cellular respiration

18. Lysosome Lysosomes hold enzymes that were created by the cell.
The purpose of the lysosome is to digest things.

19. Golgi Complex Is a packaging organelle.
It gathers simple molecules and combines them to make molecules that are more complex.
It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell.
