FAQs on Morphology in flowering plants in One Shot (NCERT) - 1 Video Lecture - Biology Class 11 - NEET

1. What is the role of morphology in flowering plants?
Ans. Morphology in flowering plants refers to the study of their external structures and forms. It helps in understanding the different parts of the plant, such as roots, stems, leaves, flowers, and fruits, and their functions. By studying morphology, scientists can identify and classify different plant species, understand their growth patterns, and analyze their adaptations to various environments.
2. How do flowers contribute to the reproductive process in flowering plants?
Ans. Flowers play a crucial role in the reproductive process of flowering plants. They contain male and female reproductive organs, such as stamens and pistils, respectively. The male reproductive organ produces pollen grains, which are transferred to the female reproductive organ through pollination. This process leads to fertilization, resulting in the formation of seeds and fruits. Flowers attract pollinators, such as insects or birds, through their colors, shapes, and fragrances, facilitating the transfer of pollen.
3. What are the different types of roots found in flowering plants?
Ans. Flowering plants exhibit various types of roots. Some common types include taproots, fibrous roots, and adventitious roots. Taproots are thick and elongated primary roots that grow vertically into the soil, providing stability and absorbing water and nutrients. Fibrous roots, on the other hand, are thin and highly branched, forming a dense network in the upper soil layers. They are efficient in absorbing water and prevent soil erosion. Adventitious roots are roots that arise from non-root plant parts, such as stems or leaves, and provide additional support or assist in nutrient absorption.
4. What is the significance of stems in flowering plants?
Ans. Stems in flowering plants have multiple functions. They provide structural support to the plant, allowing it to stand upright. Stems also transport water, minerals, and sugars between the roots and leaves through specialized tissues called xylem and phloem. Additionally, stems bear buds, which can develop into leaves, flowers, or new stems, contributing to the plant's growth and reproduction. Some stems may also store water, nutrients, or food reserves, helping the plant survive in adverse conditions.
5. How do fruits aid in the dispersal of seeds in flowering plants?
Ans. Fruits are essential structures in flowering plants that aid in seed dispersal. After fertilization, the ovary of the flower develops into a fruit, enclosing the seeds. Fruits attract animals through their colors, tastes, or aromas. Animals consume the fruits, and the seeds pass through their digestive system. Upon elimination, the seeds are deposited in different locations, away from the parent plant, increasing their chances of germination and reducing competition for resources. Some fruits have adaptations like hooks or burrs that cling to animals' fur, aiding in dispersal.
