Chapter 11: Transport in Plants

Plants, unlike humans, do not have the ability to move, therefore they must rely on the soil for nutrition and their roots to absorb it. Plants have acquired a sophisticated transportation system that includes Xylem and Phloem as a result. Imbibing, plasmolysis, and osmosis are among the topics covered in this chapter. Among other things, students learn about active transportation and transpiration. For a better understanding of this chapter, see the NCERT Biology Class 11 PDF.

Chapter 13: Photosynthesis in Higher Plants

Plants are the only food supply for all living organisms, including humans. Green plants, often known as autotrophs, use photosynthesis to create or prepare the food they require. In green plants, photosynthesis is a physicochemical cycle in which light energy is utilised to promote the mixing of organic compounds. Photosynthesis is important for two reasons: it moulds and creates the basis for all realised food chains on the planet. This chapter covers the design of photosynthetic mechanisms as well as the many processes that transform light energy into chemical energy.

As previously discussed in earlier chapters, all live cells require nutrition, oxygen, and other essential components. Furthermore, in order for tissues to function correctly, waste or dangerous substances must be eliminated on a regular basis. In the great majority of higher animals, including humans, blood is the most often utilised body fluid. Another body fluid, lymph, also assists in the transport of certain compounds. The organisation and properties of blood and lymph (tissue fluids), as well as the mechanism of blood dispersion, will be discussed in this chapter.

Chapter 19: Excretory Products and their Elimination

Given that the students had just dealt with gaseous waste in the previous chapter, it's only natural that they'd be curious about the elimination of solid and liquid waste produced by metabolic processes or excessive intake. As a result, the excretory system in humans is the subject of this chapter. Students learn about the many components of the excretory system, including the auxiliary organs. They study the process of urine generation and kidney function regulation, as well as numerous kidney diseases.

Chapter 20: Locomotion and Movement

Movement is one of the most important features of living creatures. Animals and plants may move in a number of different ways. Such voluntary motions are referred to as locomotion. Strolling, sprinting, climbing, flying, and swimming are all examples of locomotor activity. Structures controlling locomotion do not need to be distinguishable from those affecting other forms of motion. Animals' movement methods change as their habitats and situations change. Food, cover, a mating partner, ideal breeding grounds, perfect climatic conditions, and avoiding hunters are only a few of the causes for locomotion.
