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
Natural vegetative propagation occurs when plants reproduce from vegetative parts like stems, roots, or leaves. 1. Runners (Stolons): Horizontal stems that grow along the soil surface and produce new plants at nodes. Example: Strawberry, Grass. 2. Tubers: Swollen underground stems that store food and produce new shoots. Example: Potato. 3. Bulbs: Underground storage organs consisting … Read more
A flower is the reproductive structure of angiosperms (flowering plants). It consists of four major parts: 1. Calyx (Sepals): The outermost whorl, usually green. Protects the flower bud before it opens. 2. Corolla (Petals): Brightly colored to attract pollinators. Contains nectar glands. 3. Androecium (Male Reproductive Organ): Composed of stamens, each with a filament and … Read more
Artificial vegetative propagation is a method used by gardeners and farmers to grow plants more efficiently. 1. Grafting: Involves joining two different plants to combine desirable characteristics. A scion (upper part) is attached to a rootstock (lower part with roots). The grafted plant continues to grow as a single organism. Used in fruit trees like … Read more
Binary Fission in Bacteria: Binary fission is a simple form of asexual reproduction where a single bacterial cell divides into two identical daughter cells. Steps of Binary Fission: 1. DNA Replication: The bacterial chromosome duplicates. 2. Cell Elongation: The cell enlarges, and the replicated DNA moves to opposite ends. 3. Septum Formation: A new cell … Read more
Seed germination is the process by which a dormant seed resumes growth and develops into a seedling under favorable conditions. It involves a series of biochemical and physiological changes leading to the emergence of the embryonic root (radicle) and shoot (plumule). Process of Germination: 1. Imbibition: The seed absorbs water, which activates enzymes and softens … Read more
Key Differences Between Male and Female Gametophytes Feature Male Gametophyte (Pollen Grain) Female Gametophyte (Embryo Sac) Location Anther (microsporangium) Ovule (megasporangium) Development Microsporogenesis & Microgametogenesis Megasporogenesis & Megagametogenesis Number of Cells Typically 2-3 cells (vegetative and generative cells) 7 cells, 8 nuclei Gametes Produced Two sperm cells One egg cell Role in Fertilization Delivers sperm … Read more
