Read the following passage and answer the questions.Plants can get rid of excess water by a process like transpiration and guttation. Waste products may be stored in leaves, bark, and fruits. When these dead leaves, bark, and ripe fruits fall off from the tree then waste products in them are removed. Waste gets stored in the fruits in the form of solid bodies called ‘raphides’. However several compounds are synthesized by the plants for their own use especially for defence. Many plants synthesize chemicals and store them in roots, leaves, seeds, etc. for protection against herbivores. Most of the chemicals are unpleasant to taste. Hence herbivores usually do not prefer to eat such plants. Some of the chemicals are toxic and may even kill the animals that eat them.i) What are raphides? ii) How do plants protect themselves against herbivores? iii) How do plants get rid of wastes?iv) Name the processes by which plants lose excess of water.
