Fungi Flashcards
Give two advantages of Rhizopus of zygospore formation.
1) zygospore may be dispersed to a more favourable environment
2) may remain dormant for a period of time until conditions are favourable
What term is used to describe the process of asexual reproduction in yeast.
Budding
What happens to the new cells formed by budding?
Bud seperates from parent cell and form an independent yeast cell
How does sexual reproduction in Rhizopus differ from that in yeast?
Numerous spores are produced by Rhizopus.
Only one cell produced by yeast.
Give function of Rhizoids.
Provide extra surface area for absorbing nutrients from the food source.
Explain why the reproduction of sporangium is associated with asexual.
Spores are produced by mitosis and therefore are identical to the parent, there is no gamete formation or fertilization.
What means saprophytic?
Organism obtains food from a dead source
What does heterotrophic mean?
Organism cannot make its own food.
Give two examples of harmful members of kingdom fungi.
Breadmold or potato blight
Give role of Rhizoids other than anchorage.
Used to absorb food
Describe how Rhizoids absorb food.
Rhizopus secretes enzymes on the food source, which digest the food.
The rhizoids increase the surface area to make absorption of the nutrients more efficient.
What term describes the nutrition of Rhizopus?
Saprophytic
The cells of Rhizopus are described as eukaryotic.
Give two characteristics of eukaryotic cells.
Contain nucleus and membrane- enclosed organelle
They are larger than prokaryotic cells
What term is used to describe bacterial cells?
Prokaryotic cells
Explain what happens when the zygospore reaches a location at which conditions for its germination are suitable.
It germinates.
