KEY CONCEPT Fungi are heterotrophs that absorb their food.

Fungi are adapted to absorb their food from the environment. Plants and fungi have different traits. Fungal cell walls = chitin. Plant cell walls = cellulose. Plants = photosynthesize. Fungi absorb food.

Fungi are multicellular organisms, with the exception of yeasts. hyphae mycellium fruiting body

Fungi come in many shapes and sizes. Sac fungi form a reproductive sac, or ascus. Yeasts = single-celled sac fungi. Morels and truffles = multicellular sac fungi.

Bread molds are often found on spoiled food. form zygospores during reproduction

Club fungi have fruiting bodies which are club-shaped. reproductive structures called basidia include mushrooms, puffballs, and shelf fungi

Fungi reproduce sexually and asexually.

Multicellular fungi have complex reproductive cycles. distinctive reproductive structures
