Question

What are the two major stages of a plant's life cycle?

Answer 1

A life cycle is a set of events that begins with the birth of a new product and continues through its development into a mature product, critical mass, and eventual decline. Product development, market introduction, growth, maturity, and decline/stability are the most prevalent stages in a product's life cycle.

Complete answer:
1. Vegetative stage
2. Reproductive stage

Explanation: Seed germination is the beginning of an annual plant's life cycle. As a result of germination, the seedling develops into a mature plant with a separate shoot and root system. The stem and leaves make up the shoot system. This is the life cycle's vegetative stage.

Flowers, which are reproductive structures, are produced by the mature plant. The emergence of flowers on the plant marks the beginning of the transition from vegetative to reproductive stage. In the ovary section of the flower, stamens produce pollen grains and carpels produce ovules. The male and female parts of the flower are the stamen and carpel.

Pollination causes fertilisation of the ovule, which then matures into a seed. The ovary matures into a fruit. After the fruit dehisces, the seeds are distributed. In the reproductive stage, the plant produces flowers, fruits, and seeds.

After liberation, the seeds are dispersed by various agencies and germinate to form new plants, repeating the cycle.

The gametophyte stage and the sporophyte stage are two separate stages in the life cycle of plants. Male and female gametes are produced by mitosis in separate multicellular structures by the haploid gametophyte. The diploid zygote, which develops into the sporophyte, is formed by the fusion of male and female gametes.
