Cells & Organelles:

Cells & Organelles:

• Animal cells and plant cells

ANIMAL CELLS: NUCLEUS, CYTOPLASM, CELL MEMBRANE

PLANT CELLS: NUCLEUS, CYTOPLASM, CELL MEMBRANE, CELL WALL, CHLOROPLASTS & VACUOLE

Cells & Organelles:

• NUCLEUS: The brain of the cell, contains DNA.
• CYTOPLASM: The jelly filling of cell, contains water and nutrients.
• CELL MEMBRANE: The soft flexible wall around a cell, controls what goes in and out.
• CELL WALL: A hard outer wall made of cellulose, it for protection and support.
• CHLOROPLASTS:Little green balls in cells that can do photosynthesis.
• VACUOLE: An extra balloon in a cell that can contain nutrients or colours.

Why do we need a microscope?

Leaf tissue

LET'S DISCUSS ORGAN TRANSPLANTS

• What is donor transplantation?
  
  
  
• Why do we need donors?

• Do you want to be a donor? Why (not)?

Tissues

Learning goals 2.3

• You can describe and explain the following terms: tissue and cell.
  
  
• You can name the 4 tissue types and recognize them in a picture. 
  
  
• You can describe the functions of the 4 tissue types. 
  
  
• You can describe the difference between a single-celled organism and a multicellular organism. 

2.3 Tissues - important words

Cells = the building blocks of an organism

Tissue = a group of cells with the same shape and function

Extracellular material = a liquid or solid substance in between the cells 

                    Examples 

Which organ system is made up of nerve tissue?

Answer the following questions:

• Which organ system is made up of nerve tissue? 
• Which organs are made up of muscle tissue? 
• What is de difference between bone tissue and cartilage tissue?
• Do single-celled organisms also have tissues? Explain your answer.
