FAQs on NCERT Textbook: Morphology of Flowering Plants - Science & Technology for UPSC CSE

1. What is meant by the term 'Morphology of Flowering Plants'?
Ans. Morphology of Flowering Plants is a branch of botany that deals with the study of the external features of plants. It includes the study of the structure, size, shape, and relative position of various plant parts such as roots, stems, leaves, flowers, and fruits. This study helps in the identification and classification of different plant species.
2. What are the different types of roots found in flowering plants?
Ans. The main types of roots found in flowering plants are taproot, fibrous root, adventitious root, and aerial root. Taproot is the primary root that grows directly from the seed and gives rise to secondary roots. Fibrous root, on the other hand, has a cluster of thin, branched roots that grow from the base of the stem. Adventitious roots grow from the stem or leaves of the plant, while aerial roots grow from the stem above the ground.
3. What is the function of a flower in a flowering plant?
Ans. The main function of a flower in a flowering plant is to facilitate sexual reproduction. It contains the reproductive organs of the plant, including the male and female parts. The male part of the flower, called the stamen, produces pollen grains that contain the male gametes. The female part of the flower, called the pistil, contains the ovary, style, and stigma. The ovary contains the female gametes, and the pollen grains are transferred to the stigma, where they grow down the style and fertilize the ovules.
4. How do stems provide support to the plant?
Ans. Stems provide support to the plant by holding the leaves, flowers, and fruits in an elevated position. They also help in the transportation of water and nutrients between the roots and leaves. The stem's structure and arrangement of tissues provide strength and rigidity to withstand wind and other external forces.
5. What is the significance of studying morphology in botany?
Ans. The study of morphology in botany is significant for various reasons. It helps in the identification and classification of different plant species based on their external features. It also provides insights into the plant's adaptations to different environments and helps in understanding their ecological significance. Furthermore, the study of plant morphology forms the basis for various other branches of botany, such as physiology, anatomy, and taxonomy.
