Answer 1

• Multicellular (except yeast which is unicellular)

• Made of Hyphae (thread-like filaments)
• Mass of Hyphae = Mycelium
• Body above ground: Fruiting Body

Question 2

Answer 2

• Digest food before ingesting
• Heterotrophs
• 3 ways/types: Saprophytic , Parasitic , Mutualistic

Question 3

Saprophytic

Answer 3

• Decomposers
• Feeds on dead organisms/organic material

Question 4

Parasitic

Answer 4

Absorb nutrients from living cells of host.

Question 5

Mutualistic

Answer 5

Live in a Mutualistic relationship with another organism.

Question 6

How do fungi reproduce?

Answer 6

• Asexually: Mitosis, Fragmentation, Budding, Spores
• Sexually: Producing spores through meiosis

Question 7

List the common names of the 5 phylums in Kingdom Fungi

Answer 7

• Chytrids
• Common Mold
• Sac Fungi
• Club Fungi
• Imperfect Fungi

Question 8

Chytrid

Answer 8

• Some saprophytic or parasitic
• Most aquatic
• Likely the first fungi + evolutionary link between fungus-like protists and fungi

Question 9

Answer 11

• Mushrooms

Question 12

Imperfect Fungi

Answer 12

Athlete’s foot

Question 13

Lichens

Answer 13

• Symbiotic relationship: Fungus + Algae
• Algae provides food ; Fungus provides place to grow
• Only needs light, air, and minerals to grow
• “Pioneer species” ; inhabits harsh environments

Question 14

Mycorrhizae

Answer 14

• Symbiotic relationship: Fungus + Plant Roots
• Plants give food ; Fungus helps increase surface area for roots for water + mineral absorption
• 80-90% of plants have this
