1. What are the Chapter Names of Class 11 CBSE Biology?
Ans: The names of chapters are The Living World, Respiration in Plants, Morphology of Flowering Plants, Plant Growth and Development, Anatomy of Flowering Plants, Locomotion and Movement, Digestion and Absorption, Structural Organisation in Animals, Breathing and Exchange of Gases, Cell The Unit of Life, Biomolecules, Body Fluids and Circulation, Cell Cycle and Cell Division, Transport in Plants, Biological Classification, Mineral nutrition, Plant Kingdom, Photosynthesis in Higher Plants, Animal Kingdom, Excretory Products and their Elimination, Neural Control and Coordination and Chemical Coordination and Integration.
2. What is the Importance of Transpiration in Plants?
Ans: You must note that transpiration plays a vital role in plants. Besides dispersing extra water from the aerial plant parts, transpiration also helps in keeping the cell turgid. Plus, the process also makes the leaf surface cool, aids in the growth and development of plants regulates the temperature of a plant and facilitates mineral movement from soil to different plant parts.
3. What is Meant by Facilitated Diffusion?
Ans: Also considered as a passive procedure, facilitated diffusion is one of the transport procedures that are brought by proteins termed as permeases. Transport reaches the highest level when the available protein is saturated, and this process allows only the passing of specific molecules. Two proteins that assist in facilitated diffusion are porins and aquaporins. Moreover, facilitated diffusion is possible through symport, antiport and uniport processes.
4. What Kind of Substances are usually transported in Plants and what are the Pathways for their Transport?
Ans: A wide variety of substances are usually transported in flowering plants. However, the most commonly transported substances include water, mineral nutrients, organic nutrients or food and plant growth regulators. The transport of water in plans is primarily carried out by conductive tissues and individual cells of the vascular system. The movement of water in plants which enters the root hairs and xylem through either apoplast or symplast pathways is guided by the water potential gradient. This is the manner in which water is carried from the roots to the stem and other parts of the plant. On the other hand, organic nutrients or food is transported in plants through the phloem. During transportation, the energy from ATP is utilized to generate an osmotic pressure that allows for movement of food from higher concentration to lower concentration.
5. What are the Two main Types of Diffusion Mechanisms Employed for Transport in Plants?
Ans: The different mechanisms of diffusion that are employed for transport in plants include:
Simple Diffusion: This mechanism is employed for transporting over small distances or from cell to cell. The substances simply move from a region of high concentration to a region of low concentration in a random manner with no expenditure of energy.
Facilitated Diffusion: This transport mechanism is aided by special proteins that allow certain substances that otherwise find it difficult to move. This type of mechanism also does not allow for energy expenditure but allows for the movement of substances from higher to lower concentration regions and vice versa.
6. Are Gases transported in Plants? If yes, explain how.
Ans: Yes, gases are transported in plants along with water and organic nutrients. The primary receptor organs for the transport of gases in plants are the leaves. Leaves have specialised cells called the stomata which are enclosed by the guard cells. The opening and closing of guard cells surrounding the stomata responsible for the exchange and transport of gases such as oxygen and carbon dioxide in plants. The stomatal cells are also responsible for the evaporative loss of water by the plants.
7. Why should you refer to CBSE Class 11 Chapter 11 Notes PDF?

8. Which are the best notes for Chapter 11 of Class 11 Biology?
Ans: Vedantu’s Revision Notes of Chapter 11 of Class 11 Biology are the notes books for students to follow to get good grades in their Class 11 Biology exam. These notes are designed by subject experts to fulfil the needs of the students. They can refer to these notes while preparing for their exam and get a mastery of the concepts. The language that is used in these notes is simple to comprehend so that they are not left behind on any concepts.
9. Is Chapter 11 of Class 11 Biology easy?
Ans: Everything is easy when one is confident with what they have learnt. For this, students must follow a routine and dedicate proper time to Chapter 11 of Class 11 Biology. They should try to follow this schedule regularly, to achieve the desired results. They should read the chapter thoroughly, and mark all the important points. Along with this, they should follow Vedantu’s Revision Notes for Chapter 11 of Class 11 Biology. These notes are a great resource for last-minute revision before the exam.
10. What are the different means of transport?
Ans:
DIFFUSION - It is a passive movement from one part of the cell to another or from one cell to another. In this process, no energy is used. It is a slow process of molecules moving from a region of high concentration to low concentration.
FACILITATED DIFFUSION - It is the transport of molecules from high concentration regions to low concentration with the support of the transport molecule.
ACTIVE TRANSPORT - This type of transport uses energy to pump the molecules against the concentration gradient and is usually carried out with the help of membrane proteins.
11. What is transpiration?
Ans: Transpiration is the process by which plants give out excess water. Plants just require a limited amount of water for their survival, and so they give out the remaining excess water through the process of transpiration. It can be said to be a process of evaporation where the water is lost through the stomata. The student needs to read the chapter thoroughly to be able to understand the process and point out the different parts that take place in the process.
