You will learn about the essential activities that keep plants alive, from making their own food to transporting vital substances throughout their bodies. Understanding these processes helps us appreciate the critical role plants play in our environment. Your study route Key topics Photosynthesis is the process by which green plants, using chlorophyll, convert light energy into chemical energy to synthesize food (glucose) from carbon dioxide and water. Oxygen is released as a byproduct. Example The leaves of a plant absorb sunlight, carbon dioxide enters through stomata, and water is absorbed by roots. Inside the chloroplasts, these are used to make sugar. Watch out Students often confuse photosynthesis with respiration, thinking they are the same or that plants only photosynthesize.

Why it matters This process is fundamental to almost all life on Earth, as it produces the food and oxygen necessary for most organisms, including humans. Watch out Students often confuse photosynthesis with respiration, thinking they are the same or that plants only photosynthesize. Ask at home Ask your child to list the ingredients and products of photosynthesis and explain where each comes from or goes. Plants, like all living organisms, perform various life processes to survive and grow. This chapter focuses on key processes such as photosynthesis, where plants use sunlight, water, and carbon dioxide to produce food (glucose) and oxygen. It also covers respiration, the process by which plants break down food to release energy. The transport system in plants, involving xylem for water and minerals and phloem for food, is explained. Additionally, the chapter touches upon transpiration, the loss of water vapor from leaves, and how plants reproduce. Understanding these fundamental processes reveals the intricate mechanisms that enable plants to thrive and support life on Earth.

What you should learn Keep these close Photosynthesis uses carbon dioxide, water, and sunlight to produce glucose and oxygen. Chlorophyll, found in chloroplasts, is essential for photosynthesis. Respiration breaks down glucose to release energy, consuming oxygen and releasing carbon dioxide. Plants respire continuously, day and night. Xylem transports water and minerals from roots to leaves. Phloem transports food (sugars) from leaves to all parts of the plant. Transpiration is the loss of water vapor from leaves, aiding water uptake and cooling. Stomata are tiny pores on leaves that regulate gas exchange and transpiration. Plants can reproduce asexually (e.g., stem cuttings) or sexually (e.g., seeds from flowers). Life processes like photosynthesis, respiration, and transport are interconnected and vital for plant survival. Common confusions It is easy to think Plants only photosynthesize during the day and only respire at night. The clearer idea Plants photosynthesize only when light is available (usually day), but they respire continuously, day and night, to obtain energy for their life processes. It is easy to think Plants 'breathe in' carbon dioxide and 'breathe out' oxygen, just like animals 'breathe in' oxygen and 'breathe out' carbon dioxide. The clearer idea While plants take in carbon dioxide for photosynthesis and release oxygen, and take in oxygen for respiration and release carbon dioxide, the term 'breathing' is typically reserved for animals. Plants exchange gases through stomata, which is a different mechanism. It is easy to think Water is transported to the leaves by gravity. The clearer idea Water is transported upwards against gravity through the xylem vessels, primarily driven by the 'transpirational pull' created by water loss from leaves and root pressure.
