Question

Answer in short:

1. What is multiple fission? Name two organisms that undergo this process.

2. What are spore sacs?

3. How vegetative propagation does takes place from aerial stems?

4. Name female reproductive organs of human beings?

5. Name two methods of asexual reproduction in animals along with the examples.​

Answer 1

Answer:

1. Some algae, some protozoans, and the true slime molds (Myxomycetes) regularly divide by multiple fission. In such cases the nucleus undergoes several mitotic divisions, producing a number of nuclei.
2. Definitions of spore sac. noun. organ containing or producing spores. synonyms: sporangium, spore case.
3. Vegetative Propagation by Stems
4. Vegetative propagation occurs through stems when new plants arise from the nodes. This is where buds are formed, which grow into new plants. ... As these runners grow, buds form at the nodes, which later develop the roots and shoots, resulting in the formation of a new plant.
5. A female's internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries. The vagina is a muscular, hollow tube that extends from the vaginal opening to the uterus. Because it has muscular walls, the vagina can expand and contract.
6. Binary fission, budding, fragmentation, etc. are the examples of asexual reproduction. Budding: In this mode, a part of the organism starts bulging out. Slowly it grows and develops into a separate individual.
