NCERT Solutions for Class 11 Biology Chapter 11 – Transport in Plants
The transport process that takes place in plants is covered in-depth in Chapter 11 Biology. The chapter talks about how different nutrients make their way from one cell to another in plants. It covers many different topics such as active transportation, diffusion, facilitated diffusion, the relationship between plants and water, movement of water across different parts of a plant, osmosis, imbibition of plants, and plasmolysis. Photosynthesis and Transpiration will also be explained in the chapter.

Introduction to Transport in Plants
Transport of water in plants along with multiple processes like transpiration, diffusion, etc. are discussed in the Biology Chapter 11. Plants absorb food and water with their roots and like animals, they cannot search for these things. The water absorbed by them is transported to their multiple different parts with the help of their stem and roots. Plants prepare their food in the leaves which is then transported through the phloem. The entire process of water and food transportation in plants can be understood with the help of this chapter which is why studying it in detail is a must. The primary mediums for water transportation are transpiration and photosynthesis.

Class 11 Biology Chapter 11 Transport in Plants NCERT Solutions
Plants have tissues that assist in the transportation of minerals, water, and nutrients. Transporting minerals and nutrients is possible because of the existence of Phloem and Xylem tissues. Xylem is made of dead cells. It is an elongated tube-like structure that aids in mineral and water transportation. Phloem on the other hand is made up of living cells and transports or translocates water and sucrose along with other sugars, amino acids, and hormones.
Questions about how substances move from one cell to another and whether moving substances require metabolic energy or not are discussed in this chapter. If you have ever wondered how a tall tree manages to receive water to the tip of it is also explained here. The process of transpiration and root pressure play an important role in executing transportation of water to the leaves. Plants do not have a circulatory system set up and require substances to move over longer distances as compared to other creatures. Water absorbed by the roots is required to reach every part of the tree (including the tip of the stem which is developing).
Food made by the leaves is required in all parts of the plant as well, including its roots. Plants are supported physically by transport mechanisms present in the vascular bundles. Phloem is found in the lower levels. The strong xylem vessels present in the root’s centre support the plant and give it strength against any force that can pull it out of the ground. To provide support to the plant against bending (caused due to plant weight and wind), xylem and phloem are present on the edges of the stems.
Marks Distribution for Transport in Plants Class 11 NCERT
The fourth Unit of Biology Class 11 includes the Transport in Plants chapter in it. The unit has a weightage of 18 marks. Both short and long questions can be asked from this chapter. Short questions that carry 1 mark and long questions that carry 5 marks can be asked in the exams.
Role of Root Pressure During the Movement of Water in Plants
The movement of water in plants is significantly affected by root pressure. Root pressure – in the form of positive pressure that develops in the plant roots – carries out the absorption of nutrients from the soil. Positive pressure contributes towards restoring the continuous chain of water molecules that are present in the xylem by giving a slight push to water. Transpiration pull causes the xylem to wither due to the tensions that are created by it. Transpiration pull is what maintains the flow of water from the roots to the shoots.
