Fungi Flashcards
What is the filamentous body of fungi called?
mycelia
The filaments making up mycelia are called?
hyphae
How do fungi obtain energy/digest food?
secreting digestive enzymes outside their bodies and absorbing the liberated nutrients.
What do the pores in the septa allow?
cytoplasmic streaming
Cytoplasmic streaming
The directed flow of cytosol (the liquid component of the cytoplasm) and organelles around large fungal and plant cells through the mediation of actin. This movement aids in the delivery of nutrients, metabolites, genetic information, and other materials to all parts of the cell. Cytoplasmic streaming occurs along actin filaments in the cytoskeleton of the cell.
Three main ways fungi get nutrients.
Breaking down dead matter. Parasitism. Mutualistic relationships.
T/F Almost every biological material can be utilized for nutrients by at least one fungi?
True
T/F Fungi produce embryos in their life cycle.
False, they mass produce spores
Fungal Spores are dispersed in what 4 ways?
Wind. Water. Spewing. Digestive track of animals.
T/F Fungal spores are everywhere?
True.
What are the two modes of fungal reproduction?
Sexual and Asexual.
Fungi cell walls are made of?
Chitin, a carbohydrate, and the same material that makes up the exoskeleton of insects.
Where are fungi’s spores produced?
in the mycelium
What are fruiting bodies?
temporary structures that protect the fungus during reproduction.
Fungi spend most of their life in a feeding form called_____ but send up ______ to release _____.
hyphae, fruiting bodies, spores
Are fungi heterotrophs or autotrophs?
heterotrophs
How do fungi “digest” their food?
they digest prior to eating, then taking it in through absorption.
How do fungi get their nutrients and energy?
absorption. The process begins with the release of digestive enzymes, from the fungus, through their cell walls to digest food that is around them. The digested food is them “absorbed” through their cell wall.
