The Fungi Kingdom

Untitled Slide

• Reproduction for mushrooms: spores
• Carried by air or water currents
• Spores have protective coat
• Needs a proper environment to grow

Mushrooms

• Hypha grows out and begins to eat
• Growing produces more Hyphae
• Larger form is called mycelium
• In time then produces a fruit called..

PARASITES

• Fungus that grows on the body or in
• Athletes Foot
• Tape worm
• Other parasite...can be stagnant for years

Mould and Yeast

• Mould grows on breads you
• Fruiting bodies called: sporangia
• Yeast stays a microorganism
• When they grow they just reproduce
• They stick to themselves and are called "buds"

Yeast

• What do you think yeast needs to grow?
• Thursday we will do a lab
• Predict what you think will happen
• Three options: yeast/water, yeast/brown sugar, yeast/white sugar
• Write a prediction in your journals

BACTERIA

Bacteria

• Found every where
• Shaped: spherical, spiral or rod-shaped
• Reproduce: with fission (bacteria/2)
• Replication can happen fast! (20 mins)
• When in danger, can form spores to hide

BACTERIA

• Can feed on the insides of living bodies
• Examples: whooping cough, cholera, typhoid
• Food poisoning is a common bacteria problem

USEFUL BACTERIA

• Yoghurt: bacteria in milk and let it go sour
• Vinegar: allowing other bacteria to feed on ethanol
• Blue-green Algae line in seas, oceans and lakes

The Protoctista Kingdom

Protoctista

• Some get energy from the sun
• Others feed like animals (often called uni-cellular animals)
• Three types: Cell with long hair (flagellum)
• Cells with a coating of hairs (cilia)
• Cells with no hair- but a foot like structure (pseudopodia)

DECOMPOSERS

• Bacteria, fungi and insects
• Release nutrients into the soil from dead bodies or plants
• Left overs leave the soil full of nutrients
