00:00PLANTS ARE USEFUL
00:04Plants are very important in our lives.
00:11Plants give us food to eat, fresh air to breathe, wood to build houses and many more things.
00:24In the previous chapter, we learnt that plants store food in them.
00:32A lot of food we eat like fruits and vegetables, cereals and pulses and so many other goodies
00:44come from these storehouses in plants.
00:50Most of the food we eat comes from different parts of a plant's body.
00:59But all the parts of every plant or tree are not edible.
01:08Animals also eat different parts of plants.
01:15Apart from fruits and vegetables, we also get different grains and pulses from plants.
01:27We eat grains and pulses in some form or the other every day.
01:37Grains and pulses have to be cooked before eating.
01:45Grains and pulses are grown as crops.
01:52Crops are usually cultivated by farmers in huge fields and plantations.
02:02All the crops don't grow throughout the year.
02:07Different crops are grown in different seasons.
02:14Every season the farmer plants and harvests new crops.
02:23Some crops like cocoa, sugarcane, coffee and tea undergo various processes before we can use them.
02:41Sugarcane is a giant grass.
02:48The stalks contain a sweet and juicy sap.
02:55We can peel and directly suck the natural juice.
03:00It is very tasty.
03:04Sugarcane is mostly used to make sugar and jaggery.
03:11We use herbs and spices to add flavor to our food.
03:19Cardamom, pepper, hing, jeera, cinnamon and fennel are some spices you will find in every kitchen.
03:37A spice could be a dried seed, root, bark or fruit of plants.
03:48We also get oil from certain plants.
03:55Oil is used for cooking.
04:00Did you know that pencils are made of wood?
04:07We use wood to construct our homes.
04:12Wood usually comes from the branch or the trunk of a plant.
04:20Bigger plants like trees give more and stronger wood.
04:29Apart from the food and wood, we also get many products like rubber, gum, medicines and various fibers from plants.
04:47Rubber is used for making tires, pipes and many other things.
04:57Cotton and jute are two types of plant fibers.
05:04Neem, tulsi, turmeric and eucalyptus are used for making medicines.
05:16Not just this, even the paper you write on and the eraser you use are the products of these plants.
05:28Plants are not just useful to us, they are useful to the animals and birds too.
05:39Have you ever thought that even the fresh air you breathe is given out by plants?
05:49That is why the air in gardens and forests is so fresh.
05:58Plants, animals and people are dependent on each other.
06:06Woodpeckers feed on insects and grubs from trees, thereby keeping the trees healthy and free from insect attacks.
06:22Grasshoppers and crickets hide from their predators by taking cover in green and dry leaves respectively.
06:34Hence, every plant is very important to us and the entire universe.
