Question

What will be the fate of the following structures in angiospermic plants? Ovary wall, ovule, zygote, outer integument, inner integument and primary endosperm nucleus?

Answer 1

➡ Ovary wall will form the fruit wall.

➡ Ovule will be forming zygote after syngamy.

➡ Zygote will form the seed.

➡ Outer integument will form testa.

➡ Inner integument will form tegmen.

➡ PEN will form endosperm.

Answer 2

Angiosperms are a type of flowering plant. Flowering plants are the most common vascular plants in the world's fauna.

Fate of the structures in angiospermic plants

1. Ovary wall will form a fruit.
2. Ovule develop in to seed
3. The Zygote form an embryo of plant
4. Outer integument convert into protective outer covering of a seed; the seed coat also called testa
5. Inner integument Tagmen. Inner layer of seed coat is Tagmen which is very delicate.
6. Primary endosperm nucleus convert into endosperm of plant.

Angiosperms

• "Flowering plants" are another name for angiosperm plants. Angiosperms are a type of plant that makes up the majority of all plants on the planet.
• Wheat, corn, rice, maple seeds, beans, and corns are examples of angiosperm plants that generate seeds wrapped in "fruits," which include fruits we consume as well as plants we might not think of as fruits, such as wheat, corn, rice, maple seeds, beans, and corns.
• Flowers are a distinctive feature of their reproductive anatomy, known as angiosperms. It's also known as "flowering plants," though we don't often recognise its blooms as the lovely colourful petaled objects that come to mind when we hear the name.

Characteristics of Angiosperms

1. Flowers appear on all plants at some point during their existence. Flowers are the reproductive organs of the plant, and they also serve as a means of conveying genetic information.
2. The sporophyte is made up of three parts: stems, roots, and leaves.
3. The vascular system is harmed by true vessels in the xylem and partner cells in the phloem.
4. The stamens, which stand for microsporophyll, and the carpels, which stand for megasporophyll, make up the flower.
5. Four microsporangia are seen in each microsporophyll.
6. The ovary encases the ovules at the base of the megasporophyll.
7. Angiosperms are heterosporous, meaning they produce both microspores (pollen grains) and a single functioning megaspore that is maintained in the nucleus permanently.
8. A single functional megaspore is preserved in the nucleus at all times.
9. Pollen grains are transmitted from the anther to the stigma in angiosperm plants, and pollination is employed for reproduction. Pollen grains carry genetic data from one flower to the next. Pollen grains are substantially smaller than reproductive or gametophytes cells and are seen in non-flowering plants.
10. Diploids or sporophytes
11. The root system, which is exceedingly complex, is made up of cortex, xylem, epidermis, and phloem.
12. Double and triple fusion occur in the flower, resulting in the formation of a diploid zygote and triploid endosperm.
13. Angiosperms may thrive in a variety of conditions, including those that are wet.
