CBSE Class 7 Science Notes Chapter 10, Download FREE PDF

Plants perform many important activities to survive and grow. They prepare food, transport water and nutrients, and release energy through respiration. These concepts are important for Class 7 students because they form the base for higher-level biology topics. Many students need simple and organised notes to revise these topics quickly before exams and class tests.

These CBSE Class 7 Science Notes Chapter 10 explain all important concepts in an easy format. The notes cover photosynthesis, transportation in plants, respiration, and important plant tissues. They also help students revise definitions, functions, and important points in less time.

Life Processes in Plants Class 7 Science Notes PDF

Overview of Life Processes in Plants

The chapter explains how plants carry out different life processes to remain alive. Plants prepare their own food with the help of sunlight. They also transport water, minerals, and prepared food to different plant parts.

These CBSE Class 7 Science Notes Chapter 10 also explain the role of leaves, xylem, phloem, chlorophyll, and stomata in plant functioning. Students can use these notes for quick revision and concept clarity.

Leaf as the Food Factory

Leaves are called the food factories of plants because they prepare food through photosynthesis. Leaves contain chlorophyll, which is a green pigment that absorbs sunlight.

Important Parts of a Leaf

• Lamina – Broad flat surface of the leaf

• Midrib – Main vein present in the centre

• Veins – Carry water and food

• Petiole – Stalk that connects the leaf to the stem

The structure of the leaf helps plants absorb sunlight properly for food preparation. The diagram in the notes also shows different leaf parts clearly.

Photosynthesis in Plants

Photosynthesis is the process by which green plants prepare their own food using sunlight, water, carbon dioxide, and chlorophyll. It is one of the most important topics in the Life Processes in Plants class 7 notes.

Raw Materials Required for Photosynthesis

Plants need the following things for photosynthesis:

• Water absorbed by roots

• Carbon dioxide from air

• Sunlight as the energy source

• Chlorophyll traps sunlight

Products of Photosynthesis

After photosynthesis, plants produce:

• Glucose as food

• Oxygen is released into the atmosphere

These concepts are important in Life Processes in Plants notes because they explain how plants support life on Earth.

Photosynthesis Equation

The process of photosynthesis can be represented through a simple equation:

6CO2 + 6H2O→Sunlight, Chlorophyll→ C6H12O6 + 6O2

Students should learn this equation carefully because it is frequently asked in examinations.

Transportation in Plants

Plants transport water, minerals, and food through special tissues. These tissues form the transport system of plants. The chapter explains this topic clearly in Life Processes in Plants class 7 science notes.

Transport of Water and Minerals

Water and minerals are transported through xylem tissues. Root hairs absorb water from the soil. This water moves upward to stems and leaves through transpiration pull.

Transport of Food

Food prepared in leaves is transported to all parts of the plant through phloem tissues. This process ensures proper growth and development of the plant.

Difference Between Xylem and Phloem

Students should remember these differences because they are important for short-answer questions.

Respiration in Plants

Respiration is the process in which food breaks down to release energy. Plants require energy for growth, repair, and other life activities.

Important Points About Respiration

• Plants respire during both day and night

• Oxygen enters through stomata

• Energy is released during respiration

Respiration is different from photosynthesis. Photosynthesis stores energy in food, while respiration releases energy from food.

Respiration Equation

The respiration process can be represented by the following equation:

C6​H12​O6​+6O2​→6CO2​+6H2​O+Energy 

Students should practice writing this equation correctly during revision. 

Difference Between Photosynthesis and Respiration

Students often confuse these two processes. The table below makes it easy to understand, and it is a common question in Life Processes in Plants class 7 science notes exams.

Important Key Points to Remember

These quick points will help you revise fast before your exam. They are taken directly from the CBSE Class 7 Science Notes, Chapter 10 Life Processes in Plants syllabus.

• Leaves are the food factories of the plant.

• Chlorophyll gives leaves their green colour.

• Xylem transports water and minerals.

• Phloem transports prepared food.

• Respiration releases energy from food.

• Photosynthesis stores energy in the form of glucose.

Practice Questions

Test your understanding with these short questions:

1. What is the role of chlorophyll in photosynthesis?

2. Name the two transport tissues in plants.

3. Write the equation for photosynthesis.

4. What is transpiration pull?

5. How is respiration different from photosynthesis?

These CBSE Class 7 Science Notes Chapter 10 cover all the major topics in a clear and simple way. By understanding photosynthesis, transportation, and respiration step by step, students can score well in their science exams. Always revise the key points and practice the diagrams before your test. These CBSE Class 7 Science Notes Chapter 10 are a reliable resource for both quick revision and deep understanding of the chapter.
