Importance of Plants

1.Is a Tomato a Fruit or a Vegetable?

• Tomato is a fruit that grows on the tomato plant.
• A tomato flower matures to get converted into a fruit with seeds in it.

2.Other Than Burning Wood, Will It Be Possible to Make Fuel Out of Plants?

• It is possible to generate fuel from plant and animal waste.
• Ethanol and biogas are examples of such fuels.
• Biofuels burn with less or no smoke and hence, cause less pollution.

3. Is It True That Forests Attract Rain? How?

• Plants release water in the form of water vapour by the process of transpiration.
• More the number of trees higher is the rate of transpiration.
• Hence, an area covered with forest receives more rainfall as the amount of water vapour increases in the air.

• Plants perform photosynthesis only in the presence of sunlight during, which they release oxygen. At night they respire like animals and hence, produce carbon dioxide.
• But some plants such as Tulsi, Peepal, Aloe vera, Neem, etc., also release some amount of oxygen at night time.
