This has led to the evolution of a fascinating transportation system in plants involving Xylem and Phloem.
In this chapter, the student learns about the various aspects of the same, including Imbibing, Plasmolysis, Osmosis, Active transport and transpiration. They learn about what categorises a mineral as essential, and about the means of transportation and mechanism of absorption of the same.
They learn about the deficiency symptoms indicating the lack of said minerals too, for a holistic view on the topic. They are also briefly introduced to nitrogen fixation and its significance. Class 11 Biology Chapter 13 Photosynthesis in Higher Plants Students are already aware of the basic process of photosynthesis, but fail to apppreciate its complexity due to how its presented.
In this chapter, they are introduced to the mechanism in such a beautiful way as to make them fall in love with the subject. They come to know of cyclic and non-cyclic photo-phosphorylation. Class 11 Biology Chapter 14 Respiration in Plants Photosynthesis and Respiration are the two main functions performed by plants. In this chapter, the student is introduced to the latter. They learn about phases of plant growth, growth regulators, differentiation, dedifferentiation, redifferentiation, Vernalisation, seed dormancy, etc.
They also come to know of the function played by plant hormones in plant growth and development. This chapter concludes Unit 4, Plant physiology. Class 11 Biology Chapter 16 Digestion and Absorption In this unit, the student begins to explore human physiology and learn to understand how their own bodies function.
This chapter focuses primarily on Digestion and absorption of the digested food. Digestive system disorders are also briefly discussed.
