1 19.5 Diversity of Fungi KEY CONCEPT Fungi are heterotrophs that absorb their food.

2 19.5 Diversity of Fungi Fungi are adapted to absorb their food from the environment. Plants and fungi have different traits. –Fungal cell walls are made of chitin. –Plant cell walls are made of cellulose. –Plants have chlorophyll and photosynthesize. –Fungi absorb food through hyphae.

3 19.5 Diversity of Fungi Fungi are multicellular organisms, with the exception of yeasts. – hyphae – mycellium – fruiting body

4 19.5 Diversity of Fungi Fungi come in many shapes and sizes. Primitive fungi are aquatic and have flagellated spores. Sac fungi form a reproductive sac, or ascus. –Yeasts are single-celled sac fungi. –Morels and truffles are multicellular sac fungi.

5 19.5 Diversity of Fungi Bread molds are often found on spoiled food. – form zygospores during reproduction – mycorrhizae belong to this group

6 19.5 Diversity of Fungi Club fungi have fruiting bodies which are club-shaped. – reproductive structures called basidia – include mushrooms, puffballs, and shelf fungi

7 19.5 Diversity of Fungi Fungi reproduce sexually and asexually. Most fungi reproduce both sexually and asexually. –Yeasts reproduce asexually through budding. –Yeasts form asci during sexual reproduction.

8 19.5 Diversity of Fungi Multicellular fungi have complex reproductive cycles. – distinctive reproductive structures

9 19.5 Diversity of Fungi –life cycles may include either sexual or asexual reproduction or both Multicellular fungi have complex reproductive cycles.

10 19.5 Diversity of Fungi –life cycles may include either sexual or asexual reproduction or both Multicellular fungi have complex reproductive cycles.

11 19.5 Diversity of Fungi All fungi form spores and zygotes.
