GCSEPod® Biology - Nutrition and Energy in Plants

**This is a short sample from GCSEPod® Biology - Nutrition and Energy in Plants. The full title is over 25 minutes long and includes 6 Chapters. **

Just like animals, plants need a constant supply of food in order to survive. However, unlike animals, plants don't have to eat their food. Their food is a sugar called glucose, which they make in a process called photosynthesis. Photosynthesis takes place mainly in the leaves. The raw materials that a plant needs are carbon dioxide, water and mineral salts. Without these, the plant would die. Why are each of these things essential, and where do plants get them from? Photosynthesis produces glucose and oxygen. Plants have many uses for glucose. We know that plants grow more quickly in the long, warm, sunny days of summer. Photosynthesis must happen more quickly under these conditions, so what factors can affect the rate of photosynthesis, and are there any limits to how fast plants can grow?
