4. Filamentous - Made of Hyhae
5. No tissue - ie muscle or nervous
6. Multicellular (except for yeast)

Question 3

Answer 3

Chitin

Question 4

Question 6

What is unique about yeast as a fungi?

Answer 6

It is unicellular rather than multicellular which all other fungi are.

Question 7

What is the main structure of fungi made up of?

Answer 7

Hyphae - spreads under ground eventually pushing up a fruiting body.

Question 8

What is the name given to the growth of Hyphae?

Answer 8

Apical Growth

Question 9

What is a fruiting body?

Answer 9

The Reproductive Structure

Question 10

What is the name given to the Hypae underground?

Answer 10

Mycelia / Mycelium

Question 11

Describe Hypae

Answer 11

One cell thick

Tangled together underground

Allows for greater surface area.

Grows from the Apex

Question 12

What are fungi Spores?

Answer 12

They are produced from the flowering body or hang on the Sparangiophores (exteneded hypae) and act like seeds seaking out other nutrient rich areas for more fungi.

Question 13

Where would you find a Sporangia?

Answer 13

Sporangia are found at the tips of specialised hyphae called sporangiophores.

Question 14

Do Fungi reproduce Asexually or Sexually?

Answer 14

Both!

Question 15

Describe how a Fungi reproduces Asexually

Answer 15

This occurs when Hypae break off and grow on there own.

Question 16

Describe how the fungi reproduce Sexually.

Answer 16

Two hyphae grown and come together touching. They grown and develop a Zygote which through meosis developes into a Spore.

Question 17

What are Seconday Metabolites?

Answer 17

Products that aid in the growth and development of fungi but are not required for the fungi to survive

Question 18

What is a Sparobe?

Answer 18

Fungi that obtain food from decaying matter. Most fungi are this.

Question 19

What are parasites?

Answer 19

They harm there host organisum whilst living on them. Some fungi are parasites.

Question 20

Answer 20

Some fungi are Symbiants.

i.e. Algae & Fungi

Answer 21

Answer 22

By the degree of damage caused.

• Superfical - Confined to the skin hair or nails
• Subcutaneous - The skin and tissue beneath the skin
