Sexual Reproduction in Flowering Plants || in Hindi for Class 10

In this biology video in Hindi for Class 10 we explained the process of sexual reproduction in flowering plants. This is a topic from chapter 8 - 'How do Organisms Reproduce' From NCERT for class 10. Stamen : The stamen is the male reproductive part which produces pollen. A stamen typically consists of a stalk called the filament and an anther. Pollen is a powdery substance produced by seed plants. It consists of pollen grains which produce male gametes (sperm cells). Pistil : A pistil is the female reproductive part which typically consists of an expanded basal portion called an ovary, an elongated section called a style and an apical structure called a stigma that receives pollen. The ovary is the enlarged basal portion containing one or more ovules. Each ovule has an egg cell. Unisexual Flower : It contains either stamens or pistil. e.g., papaya. Bisexual Flower : It contains both stamen and pistil. e.g., lily, rose, mustard. Fertilisation : Agents, like wind, water or animal, transfer pollen from stamen to stigma. After the pollen lands on a suitable stigma, it has to reach the female germ-cells which are in the ovule. A tube, known as pollen tube, grows out of the pollen grain and travels through the style to reach the ovary. The male germ-cell fuses with the female gamete. This fusion of the germ-cells or fertilisation gives us the zygote which is capable of growing into a new plant. After fertilisation, the zygote divides several times to form an embryo within the ovule. The ovule develops a tough coat and is gradually converted into seed coat. The ovary grows rapidly and ripens to form a fruit.Meanwhile, the petals, sepals, stamens, style and stigma may shrivel and fall off. The seed contains the embryo which develops into a seedling under appropriate conditions. This process is known as germination. 👇👇👇👇👇👇 𝑷𝑳𝑨𝒀𝑳𝑰𝑺𝑻 👇👇👇👇👇👇 🔴 Click here to watch the whole playlist on Chapter 8 : 'How do Organisms Reproduce' for Class 10 :    • Modes of Reproduction used by Single Organ...   👇👇👇👇👇👇 𝑷𝒓𝒆𝒗𝒊𝒐𝒖𝒔 𝑽𝒊𝒅𝒆𝒐𝒔 👇👇👇👇👇👇 🔴 Modes of Reproduction used by Single Organisms    • Modes of Reproduction used by Single Organ...   0:00 Introduction 1:55 Stamen (Anther and Filament) 3:58 Pistil (Stigma, Style and Overy) 6:22 Unisexual and Bisexual Flower 8:24 Fertilisation
