Class 4 Evs - ICSE-SCIENCE
Plants - Parts, Functions, Photosynthesis (introduction)
This chapter introduces Class 4 ICSE students to the fascinating world of plants, exploring their main parts like roots, stems, leaves, flowers, and fruits, alongside their specific functions. Students will learn how roots absorb water and hold the plant firmly in the ground, while leaves act as the kitchen of the plant. The chapter also introduces the basic concept of photosynthesis, explaining how green leaves make their own food using sunlight, water, and carbon dioxide. Mastering this chapter is essential for board exams as it forms the foundational building block for future biology topics regarding living organisms and ecosystems.

Roots
Roots grow under the ground, absorb water and minerals from the soil, and hold the plant firmly in place.
Stem
The stem supports the upper parts of the plant and acts like a highway to transport water and food to all parts.
Leaves
Leaves are called the 'kitchen' of the plant because they prepare food for the entire plant using green pigment called chlorophyll.
Photosynthesis
The process by which green leaves make food using sunlight, water, carbon dioxide, and chlorophyll, releasing oxygen into the air.
Flowers and Fruits
Flowers are the reproductive parts that bloom into colorful structures, which later develop into juicy fruits containing seeds.

Board Exam Info
In ICSE Science (EVS) assessments, this chapter typically carries 8 to 12 marks. Common question types include labeling diagrams of plant parts, matching functions to plant organs, fill-in-the-blanks about photosynthesis, and short descriptive answers explaining why leaves are called the kitchen of the plant.
Frequently Asked Questions
Why are leaves called the kitchen of the plant?
Leaves are called the kitchen because they prepare food for the whole plant during the process of photosynthesis.
What do roots do for the plant?
Roots absorb water and nutrients from the soil and keep the plant standing straight and firm in the ground.
What is photosynthesis in simple terms?
It is the way green plants use sunlight, water, and air to make their own food and release fresh oxygen for us to breathe.
