Biology Chapter 24: Fungi

Heterotrophic

Consumes complex organic carbon from outside the body

External digestion

Cells release enzymes to digest and absorb nutrients

Saprophytes

Live on dead or decaying organisms

Budding

Type of asexual reproduction in which there is outgrowth of a cell on the body region resulting in separation and a new organism

Fission

Type of asexual reproduction in which there is dividing of an individual into two separate organisms

plasmogamy

Fusion of cytoplasm

plasmogamy of two haphae

First step of fungal sexual reproduction

Karyogamy of the fungal nuclei

Second and most important step of fungal sexual reproduction

Karyogamy

Fusion of nuclei

Mitosis

Last step of fungal sexual reproduction

Lichen

Mutualistic relationship between algae and fungi, in which the algae provides energy and carbon, and the fungus provides minerals, water, and protection

Chitin

Material for the cell walls of fungi

Hyphae

Slender filaments that make up fungal bodies

Septate hypha

Sectioned hyphae separated by cell walls

Coenocytic hypha

Hyphae that are not separated

Mycelium

Mass of connected hyphae
