Question

Identify 1, 2, 3, and 4 in this figure?

Answer 1

Sporophyte:

1. The sporophyte is a diploid multicellular stage of plant life.
2. A sporophyte is formed by the fusion of a haploid male gamete and a haploid female gamete.
3. It is the plant's non-sexual stage of development.

Gametophyte:

1. A gametophyte is an important stage in the life cycle of plants.
2. The haploid sexual phase of the plant life cycle is the gametophyte.
3. During the gametophyte phase, haploid male and female organisms develop and produce eggs and sperms for sexual reproduction via simple mitosis.

Rootlets:

1. The root is the underground or subterranean portion of a plant's body.
2. They provide plant anchorage in the ground, allowing the plant to stand upright properly.
3. Any surplus or excess sugars produced during photosynthesis are stored in the roots.

Rhizoids:

1. Rhizoids are simple, hair-like projections that grow from bryophyte epidermal cells.
2. Rhizoids function as roots, essentially anchoring the plants to the surface.
3. It can function as a feeding organ, as in Rhizopus, or as an anchoring organ, as in Chytridium.
4. Rhizoids, which are found in plants such as liverworts and mosses, attach the gametophyte to the substratum and aid in mineral and water absorption.
