NCERT Exemplar Class 11 Biology Chapter 13 Solutions: Photosynthesis in Higher Plants

NCERT Exemplar Solutions for Class 11 Biology Chapter 13 you will find out that mesophylls cells existing in leaves have a large number of chloroplasts, which are accountable for setting carbon dioxide. The process of photosynthesis can be divided into two stages that is the light reaction and the carbon fixing reactions. Other main topics in this chapter of NCERT Class 11 Biology Exemplar include photorespiration, where does photosynthesis take place, electron transport, factors affecting photosynthesis, number of pigments involved in Photosynthesis.

Class 11 Biology NCERT Exemplar Chapter 13 has 4 main exercises with around 59 exemplar problems in total. The different types of questions include objective type questions, very short answer type questions, short answer types questions as well as long questions. The expert Biology teachers at Instasolv have presented the solutions in an easy to understand language to assist you in preparing the chapter in a quick time.

Important Topics for NCERT Biology Exemplar Solutions Class 11 Chapter 13 – Photosynthesis in Higher Plants

Introduction

Photosynthesis is a procedure by which plants generate their food for themselves by using sunlight. This method was first seen in organisms that were alike to bacteria. Evidence presented that they did not engage visible light, as a substitute, they used near-infrared and formed sulphur or sulphate compounds. It would be extra 470 million years until the first land plants developed.

Joseph Priestley Experiment

He surrounded a mouse within a bell jar and after some time, the mouse actually died. He simulated the same experiment with a blowing candle and finally, the flame was turned off. But when he repeated the above experiment with a mint plant, the mouse lived and the flame continued. This result led Priestley to achieve that plants donate to the production of oxygen.

Where Does Photosynthesis Take Place?

Basically, this procedure takes place inside a plant cell organelle known as the chloroplast. These organelles are present in the mesophyll layer, which is generally two layers of cells available inside the leaves of the plant. Chloroplasts orient themselves through the walls of the mesophyll cells so as to garner most of the light occurring on it. The membranous system in the chloroplast containing grana, the matrix stroma, and stroma lamellae show division of labour. The system is in charge of tricking light energy, also for the ATP and NADPH synthesis, with the transmission of light reactions and dark reactions.

Photorespiration

There is no creation of ATP or NADPH in this procedure. Here, the plants consume oxygen and release carbon dioxide. This occurs in the presence of light.

Factors Affecting Photosynthesis

The various factors affecting the process of photosynthesis include:

  • Light
  • Water
  • Temperature
  • Carbon dioxide concentration

Light Reaction

The light reactions use light energy to make two molecules required for the next stage of photosynthesis including the energy storage molecule ATP and the decreased electron carrier NADPH. In plants, the light reactions occur in the thylakoid membranes of organelles known as chloroplasts.
