Important Topics for Lakhmir Singh Solutions for Class 10 Biology Chapter 3
Biology is an interesting subject to study but there are some topics which you might face difficulties to understand. Here, the important topics for Chapter 3 – How Do Organisms Reproduce are provided below:
Reproduction is the procedure by which all creatures multiply in number and raise their population.
Asexual reproduction is a process of reproduction that includes only one organism. A single organism reproduces two or multiple creatures on its own. This is seen in all unicellular organisms, some multicellular organisms and in some plants.
The method of reproduction that includes two organisms; one male and one female. They produce sex cells or gametes which fuse to produce a new organism.
The Reproductive System
Male Reproductive System: The primary reproductive organ in males is a pair of testes. They generate the male sex cells known as sperms and also form male sex hormone testosterone.
Female Reproductive System: The human female reproductive system comprises a pair of fallopian tubes/oviducts, a pair of ovaries, and the accessory organs such as the uterus and the vagina.
Menstruation is the cyclic procedure of the discharge of the ovum from the ovary and its removal from the body when fertilization does not happen. During menstruation, the blood-rich endometrium of the uterus also breaks down while the ovum is being separated from the body. In a human body, the cycle repeats every 28 days.
Sexual Reproduction in Flowering Plants
Sexual reproduction in plants usually occurs through the flowers. Important whorls of the flowers such as androecium and the gynoecium help in the sexual reproduction of plants.
The process of transmission of pollen grains from anthers to the stigma of a flower is called pollination. It is of two types, self-pollination and cross-pollination. In self-pollination, the transmission of pollen grains takes place from anthers to the stigma of the same flower or another flower of the same plant. But in cross-pollination, pollens are transported from anthers to the stigma of another flower.
The process of union of male and female gametes is termed as Fertilization. In flowering plants after pollination, the pollens develop on the stigma surface of the pistil and create two male nuclei. After the process of fertilization, the ovary becomes fruit and ovules turn into seeds. All additional parts wither away.
