asexual reproduction in rhizopus
Answers
1.it takes place by spores formed in the sporangium.
2. A single sporangium develops at the tip of long, erect sporangiophore.
3. A dome-shaped columella is present in each sporangium. The protoplast of columella is in continuation with that of sporangiophore
4. The space between columella and wall of sporangium is known as spore sac. It remains Filled with sporangiospores or aplanospores.
5. Each sporangiospore is ovoid, non-motile, unicellular and multinucleate structure. There is no flagella on the spores.
6. Spores come out on dehiscence of sporangium and germinate immediately by forming new mycelium.
7. Another means of asexual reproduction is the formation of chlamydospores.
Answer:
asexual reproduction in rhizopus
Explanation:
The thread-like structures that develop on the decaying bread are the hyphae of commonly known as bread mould.
These hyphae have tiny blob-on-a-stick like structures known as sporangia which contain numerous spores.
Each spore can develop into new rhizopus individual.
This type of reproduction is known as asexual reproduction.
These spores are covered by thick walls that protect them until they come into contact with another nutrient filled moist surface and can begin to grow.
