Question

d) Identify the type of reproduction seen in each of the following.


1) Cat
2) Onion
3) Rose
4) Mango
5) Parrot ​

Answer 1

Answer:

1) Cat

The cat is described as being seasonally polyestrous and a long-day breeder. Queens undergo estrous cycles repeatedly during a breeding season unless interrupted by pregnancy, pseudopregnancy, or illness. Estrous cycles will occur at variable intervals but most typically every 14 to 21 days.

2) Onion

By nature, onions are biennial plants. Their natural rhythm is to grow from a seed to a plant and then into a dormant bulb in their first year. ... Fertilized flowers produce seeds, and the life cycle is complete. We, gardeners, abbreviate this cycle by growing onion seedlings and harvesting them in the same season.

3) Rose

Rose culture occurs via four methods: seed, cuttings, layering, and grafting. Seeding is the only means of propagation through sexual reproduction and allows more genetic diversity. Asexual reproduction via the other methods produces plants that are true to the parents.

4) Mango

Mango plants can also self pollinate as they are monoecious, meaning male and female reproductive organs are found on the same plant. ... Once pollinated, fruit can begin to develop on the plant. Mangos produce drupe-like fruit, meaning a single seed is encased in a leathery coating.

5) Parrot

Parrots typically lay two to eight eggs at one time. A parrot's egg needs 18 to 30 days of incubation before it can hatch, so the parents take turns sitting on the eggs. ... Parrot chicks are blind for the first two weeks of their lives. At three weeks, they start to grow their adult feathers.
