EXPERIMENT

- STEP 1: - STEP 2: - STEP 3: - STEP 4: - STEP 5: - STEP 6:

Take four slices of bread.

Put one piece of bread in a dry place, ehere there is light.

Moinsten another piece and put it in a place where there is also light.

Put the next piece in a dry, dark place.

Take the last piece, moinsten it and put it in another dark place.

Check your pieces of bread after a couple of days.

1. FUNGI

• Living things that cannot move.
• They don´t need sunlight for nutrition
• Can´t make their own food.
• Reproduce by spores
• When temperature and humidity favourable, new fungi grow.

1. FUNGI

• Types of fungi:

YEASTS

MOULDS

CAPPED FUNGI

• Microscopic
• Unicellular
• Is used in the food industry to make bread, cheese and wine.

• Microscopic
• Multicellular
• Hyphae grow in the form of clusters
• Fluffy appearance
• Feed on the remains of living things

• Has a cap
• Multicellular
• Produce spores
• Cells are agruped in long filaments (hyphae)

YEASTS

Fungi are very interesting living things. We use fungi for all sorts of things, from medicine to food. Fungi are living organisms that can’t move. Some fungi like mushrooms may look like plants, but unlike plants they can’t make their own food. We classify different types of fungi depending on their structures. 1._________ are microscopic and multicellular. Their 2._______________ grow in clusters and are fluffy. 3._____________ are multicellular and have a cap that grows above the ground. They produce 4._____________ . 5.______________ are microscopic and unicellular. They are used in the food industry to make, for example, bread.

2. PROTOZOA

• Amoebas and paramecia
• Unicellular
• Microscopic

3. BACTERIA

• Reproduce very quickly
• Many different types
• Some are beneficial (milk-yogurt)
• Othercause diseases (are treated with antibiotics)
