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.
19.5 Diversity of Fungi
• Fungi are multicellular organisms, with the exception of yeasts.
– hyphae – mycellium – fruiting body
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.
19.5 Diversity of Fungi
• Bread molds are often found on spoiled food.
– form zygospores during reproduction – mycorrhizae belong to this group
19.5 Diversity of Fungi
• Club fungi have fruiting bodies which are club-shaped.
– reproductive structures called basidia – include mushrooms, puffballs, and shelf fungi
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.
19.5 Diversity of Fungi
• Multicellular fungi have complex reproductive cycles.
– distinctive reproductive structures
19.5 Diversity of Fungi
– life cycles may include either sexual or asexual reproduction or both
• Multicellular fungi have complex reproductive cycles.
