Tissues and cells

Cells

Building blocks of an organism

How many cells does the human body consist of?

30 biljoen  / 30.000 miljard

Nerve tissue

tissue of peritoneum. (abdominal membrane)

Tissues

Cells with the same shape and function

Bones: Bone tissue

Muscles: Muscle tissue

Extracellular material

Between the cells

- Fluid: in the brain

            - Hard substance: chalky               substance in the bones

Plants

Tissues

Epidermis(tissue)

- top and bottom of the leaf

- one cell layer thick

- protects the plant

Plants

Stomata

- - Laying in between epidermal cells

- Absorb CO2 and release O2

- Bottom of leaf

Tree

Cambium

- Tissue in the trunk of a tree

- Layer of cells close under the bark

Different types of tissues

Animal cell

Cytoplasm: 

Thick liquid

Cell membrane: 

Thin layer

- fats and proteins

Cell nucleus: 

controls the cell

Animal cell

Cell nucleus

- Nuclear Plasm

- Nuclear membrane

Cells need substances

- Through cell membrane

- Special proteins

Plant cell

Same parts as animal cells

+

more

Plant cell

Cell wall: firmness

Surrounds the cell -> intercellular substance

Vacuole: bladder containing moisture

storage, firmness

Plant cell

Plastids: 

- grains with special function

- In the cytoplasm

Plastids

- Chloroplasts

- chromoplasts

- Amyloplasts

Celorganell

Parts of a cell with their own function
