Artificial vegetative propagation allows farmers to reproduce plants with desirable traits, increase yield, and cultivate plants that may not grow well from seeds. Techniques like grafting and tissue culture improve plant quality and disease resistance. Related Questions: Define cloning. Which process of a plant is supposed to be a cloning? Enlist any two suitable conditions … Read more
The ovary contains ovules, which develop into seeds after fertilization. The ovary itself matures into fruit, protecting and dispersing the seeds. Related Questions: Define cloning. Which process of a plant is supposed to be a cloning? Enlist any two suitable conditions for the germination of a seed. Explain the structure of the embryonic stem. … Read more
Apomixis is a form of asexual reproduction in plants where seeds develop without fertilization, producing genetically identical offspring. Related Questions: Define cloning. Which process of a plant is supposed to be a cloning? Enlist any two suitable conditions for the germination of a seed. Explain the structure of the embryonic stem. Explain the role … Read more
Pollination is the transfer of pollen from the anther to the stigma of a flower. It is classified into two types: self-pollination (within the same flower or plant) and cross-pollination (between flowers of different plants of the same species). Related Questions: Define cloning. Which process of a plant is supposed to be a cloning? Enlist … Read more
Vegetative propagation is a form of asexual reproduction in which new plants grow from vegetative parts such as roots, stems, or leaves, rather than from seeds. Related Questions: Define cloning. Which process of a plant is supposed to be a cloning? Enlist any two suitable conditions for the germination of a seed. Explain the … Read more
Asexual reproduction and sexual reproduction Asexual reproduction involves a single parent and produces genetically identical offspring, while sexual reproduction involves two parents and leads to genetic variation. Artificial vegetative propagation and natural vegetative propagation Artificial propagation is human-assisted, such as grafting and cutting, whereas natural propagation occurs naturally through runners, tubers, or bulbs. Scion and … Read more
Apomixis: A form of asexual reproduction in which seeds are produced without fertilization. Pollination: The transfer of pollen from the anther to the stigma of a flower. Male gametophyte: The pollen grain, which carries the male gametes in flowering plants. Epigeal germination: A type of seed germination where the cotyledons rise above the soil surface. … Read more
Sexual reproduction in plants ensures genetic diversity, which helps species adapt to environmental changes and resist diseases. It also promotes evolution by allowing the combination of different traits from two parents. In contrast, asexual reproduction produces genetically identical offspring, limiting adaptability.

The embryo sac is the female gametophyte of flowering plants. It is a seven-celled structure containing eight nuclei. It consists of one egg cell, two synergids, three antipodal cells, and a central cell with two polar nuclei. The egg cell participates in fertilization, while the central cell forms the endosperm after fusion with a sperm … Read more
Double fertilization is a unique process in angiosperms where one sperm nucleus fuses with the egg cell to form a diploid zygote, while the other sperm nucleus fuses with two polar nuclei to form a triploid endosperm. This endosperm provides nourishment to the developing embryo. Related Questions: Define cloning. Which process of a plant is … Read more
