Chapter 31 - Fungi

Karyogamy

________ produces diploid cells that undergo meiosis and produce genetically heterogeneous haploid spores.

Mutualistic fungi

________ receive nutrients from their hosts as well, but they return with activities that benefit the host.

Fungi

________ are heterotrophic organisms that feed by absorption.

Mycelium

________ (plural, ________) is an interconnected mass of fungal hyphae that infiltrates the substance on which the fungus feeds (as shown in the image attached)

algae

Fungi, like mammals, are heterotrophs: they can not produce their own food, as plants and ________ do.

organic material

Decomposers** are fungi that break down and take nutrients from nonliving ________ such as fallen logs, animal corpses, and wastes from living species.

Septa

________ have pores that are big enough to allow ribosomes, mitochondria, and even nuclei to move from cell to cell.

parasitic fungus

Pathogenic ________ includes several species that cause plant illnesses and others that cause animal diseases.

haploid

Many fungi reproduce asexually by developing as the filamentous fungus that generates (________) spores via mitosis; such species are referred to informally as molds if they form visible mycelia.

filamentous fungus

As ________ or yeasts, many fungi may reproduce asexually.

multicellular filaments

The majority of fungus develop as thin, ________ called hyphae; just a few species grow as single- celled yeasts.

progenitor of fungus

An aquatic, single- celled, flagellated protist was the ________.

Mycorrhizal fungi

________ have unique hyphae that allow them to collaborate with plants in a mutually beneficial interaction.

Fungi

________ were among the earliest land colonists, according to fossil evidence.

Fungi

________ and mammals split over a billion years ago from a shared unicellular ancestor with a flagellum, according to molecular data.

Fungi

________ in their multicellular state are made up of mycelia, which are networks of branching hyphae suited for absorption.
