Class 7 Science - MP
Life Processes in Plants
In the chapter 'Life Processes in Plants' for Class 7 Science, MP Board students explore how plants stay alive and grow. You will learn about nutrition, how plants make their food through photosynthesis, and how water and minerals are transported throughout the plant body via xylem and phloem. Additionally, the chapter covers plant respiration and excretion. Understanding these vital processes is crucial for scoring well in your MP Board exams, as questions frequently test both basic definitions and diagram-based concepts related to plant physiology.

Photosynthesis
The process by which green plants prepare their own food using carbon dioxide and water in the presence of sunlight and chlorophyll.
Transportation in Plants
The movement of water and minerals absorbed by roots to the leaves, and food from leaves to other plant parts, carried out by specialized vascular tissues.
Respiration in Plants
The process of breaking down food to release energy, taking in oxygen and giving out carbon dioxide through tiny pores called stomata.
Transpiration
The loss of water in the form of water vapor from the aerial parts of the plant, mainly through stomata, which helps in cooling and pulling water upward.
Xylem and Phloem
Xylem is the tissue responsible for transporting water and minerals, while phloem transports prepared food from leaves to the rest of the plant.

Board Exam Info
This chapter typically carries around 6 to 8 marks in the MP Board Class 7 Science examination. Common question types include short answer questions, fill in the blanks, differences between xylem and phloem, and diagram-based questions on stomata or photosynthesis.
Frequently Asked Questions
What is the main difference between xylem and phloem?
Xylem transports water and minerals from the roots to the leaves, whereas phloem transports food prepared by the leaves to all other parts of the plant.
Why is photosynthesis important for living beings?
Photosynthesis provides food for plants, which forms the base of all food chains, and it releases oxygen into the atmosphere which is essential for respiration in almost all living organisms.
How do plants breathe or respire?
Plants respire through tiny pores on their leaves called stomata, as well as through lenticels in stems and general root surfaces, exchanging oxygen and carbon dioxide with the environment.
