Transport in Plants - NEET Booster and NCERT

Transport in plants refers to the movement of water, nutrients, and other substances throughout the plant. It is essential for the proper functioning and survival of plants. The topic of transport in plants is covered in detail in the Biology syllabus for Class 11.

NEET Booster for Transport in Plants:

1. Xylem and Phloem: The transport system in plants consists of two types of tissues - xylem and phloem. Xylem transports water and minerals from the roots to the leaves, while phloem transports organic substances like sugars from the leaves to other parts of the plant.

2. Water Transport: The movement of water through the xylem is primarily driven by transpiration, which is the loss of water vapor from the leaves. This process creates a suction force, known as the transpiration pull, which pulls water up from the roots. The cohesion-tension theory explains this mechanism.

3. Mineral Transport: Minerals are absorbed by the roots through active transport and are transported through the xylem. This process involves the movement of ions against the concentration gradient. Mineral uptake is facilitated by mycorrhizal associations and root hairs.

4. Phloem Transport: Phloem transports organic substances like sugars, amino acids, and hormones throughout the plant. The movement of substances in the phloem occurs through a process called translocation. This process requires energy and involves the movement of substances from source to sink.

5. Transport in Leaves: Leaves have specialized structures called stomata, which control the exchange of gases and the loss of water. The opening and closing of stomata are regulated by guard cells. The movement of water and nutrients within the leaf occurs through veins and mesophyll cells.

NCERT for Transport in Plants:

1. Chapter 11 - Transport in Plants: This chapter in the Class 11 Biology NCERT textbook covers the various aspects of transport in plants. It includes topics such as the structure and function of xylem and phloem, the mechanism of water transport, the role of minerals in plant nutrition, and the process of translocation in phloem.

2. Diagrams and Illustrations: The NCERT textbook provides detailed diagrams and illustrations to help students understand the concepts better. These visuals depict the structure of xylem and phloem, the movement of water and minerals, and the process of translocation in phloem.

3. Key Concepts and Definitions: The NCERT textbook explains key concepts and provides definitions for important terms related to transport in plants. It also includes examples and real-life applications to enhance understanding.

4. Exercises and Solutions: The textbook contains a variety of exercises and questions at the end of each chapter. These help students assess their understanding and practice the application of concepts. The solutions to these exercises are also provided, allowing students to check their answers and clarify any doubts.

In conclusion, the NEET booster for transport in plants provides additional information and insights, while the NCERT textbook for Class 11 Biology serves as the primary resource for understanding the fundamental concepts of transport in plants.
