NCERT Solutions for Class 11 Biology Chapter 13: Important Topics

Photosynthesis is very much important for plants. Through this process, they can make food for themselves. In addition, plants rely on sunlight to synthesise nutrients from carbon dioxide and water. In this chapter, students will learn about photosynthesis in higher plants in detail. Chapter 13 covers all these concepts in its important topics.

The most important topic from this chapter is photorespiration. However, electron transport and the factors affecting photosynthesis are also important topics in this chapter. Students can also learn about this chapter for free at Embibe. They can read and watch free 3D videos on photosynthesis. So, start learning from Embibe and practice questions to score better marks.

NCERT Solutions for Class 11 Biology Chapter 13: Points to Remember

Some of the important points to remember from this chapter are as follows:

Green plants create their own food through a process known as photosynthesis.

There are two stages to photosynthesis: the light reaction and the carbon fixing reactions.

The PS-I has 700 nm absorbing chlorophyll- a P700 molecule, while PS-II has a P800 reaction centre that absorbs red light at 680 nm.

PS-I is involved in both cyclic and non-cyclic transport, whereas PS-II is only involved in non-cyclic transport.

PS-I is concerned with ATP production, whereas PS-II is concerned with both ATP and NADPH2.

FAQs on NCERT Solutions for Class 11 Biology Chapter 13

Q.1: What are light reactions and dark reactions in Class 11 Biology?

Ans: The light reaction is the starting stage of photosynthesis which traps light energy to produce ATP and NADPH. In contrast, the dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.

Q.2: What are the factors that affect photosynthesis?

Ans: Carbon dioxide, light, temperature, water, oxygen, minerals, and pollutants affect photosynthesis.

Q.3: Where can I get the NCERT Class 11 Biology Chapter 13 Solutions?

Ans: Students can get NCERT Class 11 Biology Chapter 13 Solutions at Embibe.

Q.4: How many exercises are there in NCERT Class 11 Biology Chapter 13 Solutions?

Ans: There are 10 exercises in NCERT Class 11 Biology Chapter 13 Solutions.

Q.5: Where can I practice NCERT Solutions online?
