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

1. What is the anatomy of a flowering plant?
Ans. The anatomy of a flowering plant refers to the internal structure and organization of its various parts. It includes the study of tissues, cells, and organs such as stems, roots, leaves, and flowers. Understanding the anatomy helps in comprehending the functions and processes carried out by different plant parts.
2. What are the different types of tissues in flowering plants?
Ans. Flowering plants have three main types of tissues: dermal, ground, and vascular tissues. Dermal tissues form the outer protective covering of the plant, ground tissues are responsible for photosynthesis and storage, while vascular tissues facilitate the transport of water, minerals, and nutrients throughout the plant.
3. How are the stems of flowering plants classified based on their structure?
Ans. Stems of flowering plants can be classified into herbaceous and woody stems. Herbaceous stems are soft, flexible, and usually green, while woody stems are hard, rigid, and brown in color. Woody stems have secondary growth, which results in the formation of wood and bark.
4. What is the importance of roots in flowering plants?
Ans. Roots play a crucial role in flowering plants. They anchor the plant in the soil, provide support, and absorb water and nutrients from the soil. Roots also store food and help in vegetative propagation. Additionally, they assist in preventing soil erosion and contribute to the overall stability of the plant.
5. How are flowers essential for the reproductive process in flowering plants?
Ans. Flowers are the reproductive structures of flowering plants. They contain male and female reproductive organs, namely stamen and carpel. The stamen produces pollen grains, which are transferred to the carpel through pollination. Fertilization occurs when the pollen grain reaches the ovule in the carpel, leading to the formation of seeds. Flowers are vital for the continuation of plant species through sexual reproduction.
