Both Gametophyte and Sporophyte are the two Generations of a plant.

Both Gametophyte and Sporophyte are the two Generations of a plant.

Alternation of generations is a life cycle that includes both haploid and diploid multicellular stages. It is divided into two parts N haploid and 2n diploid. It was discovered by Strasburger. It is the conversion of gametophyte generation into sporophyte generation and vice versa. Diploid means two sets of chromosomes (2n), one set of chromosomes from male parents and another set of chromosomes from female parents. On the other hand, haploid means one set of chromosomes (n) (that carry genetic information). Multicellular contains more than one cell and unicellular is containing only one cell. In plants, lifecycle is completed by multicellular haploid cells whereas in humans, it is undergone through unicellular haploid cells. [Image will be uploaded soon]

Below is a Tabular representation highlighting some of the differences between Sporophyte and Gametophyte stages of the Plant Life Cycle.

Ans. It means that the gametophytes phase of the plant can prepare its own food and doesn’t depend upon sporophytes for any nutrient. On the other hand, sporophytes depend upon gametophyte for food and are weaker than the gametophytic phase.

Ans. Following events take place during the life cycle of a flowering plant.

All of these stages in the lifecycle of a flowering plant leads to the beginning of a new plant through a seed. Here, the seed sprouts forming a seedling which in turn is converted into a new plant. It forms new seeds and this way the cycle continues.

Ans. Alternation of generations between sporophyte and gametophyte takes in the following stages:

Sporophyte generation produces spores.

Gametophyte generation results in the formation of gametes.

Sporophytes have two sets of chromosomes.

These have a single set of chromosomes.

During meiosis, diploid spore mother cell results in the formation of haploid meiospores.

Gametes take part in fertilization or fuse together to give rise to diploid (2n) zygote.
