Biology unit 4 study guide

Prokaryotes are generally simpler and smaller than eukaryotes, whereas eukaryotes have a nucleus and other specialized organelles. The function of the Golgi apparatus is to modify, sort, and package proteins and other materials from the endoplasmic reticulum for storage in the cell or secretion outside the cell. J is the cell wall, which provides support and protection for the cell.

Front Back Which of the following characterstics or structures exist for the vast majority of fungi? Which are present only in a few species?

What do they mean? Like an iceberg, the visible part of a mushroom is only a small fraction of the total mushroom, because the mycelium is the largest component of a mushroom.

What is the difference between septate and non-septate hyphae? Septate hyphae have cell walls to seperate the cells while non-septate hyphae do not. What is the function of the rhyzoid hyphae? The rhyzoid hyphae supports the fungus and digest the food.

What is the function of the stolon? What is the function of the sporophore? A sporophore releases spores for reproduction. What is the function of the haustorium?

A haustorium invades the cells of a living host to absorb food directly from the cytoplasm. Which of he following hyphae are aerial? What is the difference between sporangiophore and a conidiophore?

A sporangiophore produces its spores in an encloser; a conidiosphore does not. What is the main characteristic of phyla Basidiomycota? Forms sexual spores on club-like basidia. What is the main characteristic of phyla Ascomycota? Forms sexual spores in sac-like asci. What is the main characteristic of phyla Zygomycota?

Forms sexual spores where hyphae fuse. What is the main characteristic of phyla Chytridiomycota? What is the main characteristic of phyla Deuteromycota?

Fungi with no known method of sexual reproduction. What is the main characteristic of phyla Myxomycota? Fungi that look like protozoa for much of their lives.

Describe the life cycle of a mushroom. A mushroom begins life as a small mycelium that grows from spores which have come from another mushroom. As the mycelium grows, it might encounter a compatible mycelium. As the two mycelia begin to intertwine, their hyphae will sexually reproduce.

Eventually the newly-produced hyphae will form a complex web and enclose themselves in a membrane. When the hyphae are formed in the membrane, it has reached its button stage.

At that point, the hyphae begin filling with water quickly, and eventually its fruiting body is formed, when the stipe and cap break through the membrane.Hey Guys, this from that test, but I think it'll work Learn with flashcards, games, and more — for free.
