DISCOVERING FACTS • Find out the different ways by which seeds are spread: • By Air: • By Bird : • By insects: • By animals: • By Water: • By Human beings:
Did you know this? From South America long ago, came a tomato, a potato, and a green chilli. Did you know this? A cabbage came from Europe, and also a pea. From Africa came a coffee bean, and a green bhindi. They crossed the land. They crossed the sea. Did you know this?
Did you know this? …A mango sang, ‘Come in! Come in!’ An orange smiled inside its skin. ‘Welcome to India,’ a banana said. the methi and spinach, brinjal and radish, nodded its head. Did you know this?
SPROUT : A sprout is a small growth on a plant. A little new bud. Germination: germination is the process which plants emerge from seeds and being growth. GERMINATION OF PLANTS
Plants which hunt! There are some plants which trap and eat frogs, insects and even mice. The Pitcher plant (Nepenthese) is one such plant. It is found in Australia, Indonesia and Meghalaya in India. It has a pitcher-like shape and the mouth is covered by a leaf. The plant has a special smell that attracts insects to it. When the insect lands on the mouth of the plant, it gets trapped and cannot get out. What a clever way to hunt!
TYPES OF PITCHER PLANT • 1. NEPENTHESE • 2. SARRACENIA • 3. VENUS FLYTRAP
