  1. 1. PLANTS AROUND US  INTRODUCTION  DIFFERENT TYPES OF PLANTS  WHERE PLANTS LIVE?  DIFFERENT TYPES OF LEAVES  PARTS OF PLANTS AND ITS FUNCTIONS  FOOD FROM PLANTS  USES FROM PLANTS FOR US AND ANIMALS  HOW PLANTS MAKE THEIR OWN FOOD?
  2. 2. INTRODUCTION Plants are living things. They breathe and grow. They also reproduce. Most of the plants grow on land. Some plants grow in water. Plants are very useful to us. Plants can be found in different shapes, sizes and colors. Some plants are big and strong. Some plants are small and weak.
  3. 3. DIFFERENT TYPES OF PLANTS  BIG PLANTS: Trees  SMALL PLANTS:  Shrubs  Herbs  Climbers  Creepers  Thorny plants  Water plants  Wild plants  Weeds
  4. 4. BIG PLANTS  Tall, big and strong plants are called TREES.  They usually live for a long time.  Some of them have bright flowers during a few months.  Others give us fruit.  Many trees have leaves all the year round.  Others shed their leaves in winter.  Some trees are peepal tree, palm tree, ashok tree, pine tree and neem tree.  Trees have strong woody barks and have many branches.  They stand erect.  They have a thick, brown and woody stem called TRUNK.  Trees give us shade, fruits and wood.

  50. 50. HOW PLANTS GROW AND CHANGE(Different parts of a plant and its functions)
  51. 51. ROOTS  The root of a plant grows below the ground.  These roots give support to the plant.  Roots hold the soil particles firmly and fix the plant in the soil.  They help the plant to stand erect.  These carry water, minerals and nutrients from the soil for the plants.  Vegetables like carrot, beetroot, turnip and radish are actually roots.  The excess food prepared by the leaves is stored in the roots of some plants. Like potato, carrot, radish and beetroot.  Types of root:  Tap root: it has a main thick root and out of the thick root grows a number of thin roots. Mustard, bean and balsam have tap roots.  Fibrous root: Large numbers of roots grow at the end of the stem. Rice, wheat and onion has fibrous roots.
  52. 52. STEMS  The stem usually grows above the ground.  Stems may be green or brown.  Stems may be thick or thin.  The stem supports its other parts of the plant such as the branches, leaves, fruits and flowers.  The stems of trees are strong and hard and these are called trunks.  They carry food and water to all parts of the plants.  The thin tubes in the stem carry the water and minerals absorb by the roots to stem and leaves.  They provide support to the plants.  Some stems like sugarcane, ginger and potato store food and can be eaten.  Stem is known as the back-bone of the plant.
  53. 53. LEAF  The green flat part of the plant.  leaf grows on the branch of the plant.  Produces food for the plant through photosynthesis. Makes food in the presence of sunlight, using water, carbon dioxide and chlorophyll.  Different parts of the leaves:  Chlorophyll: the substance which gives most leaves its green color.  leaf blades: the flat part of the leaf.  Veins: the fine lines on the leaf which give it support and carry water to the leaf.  stomata: tiny pores on the underside of the leaf blade through which the plant breathes in air. • Leaves as food like spinach, lettuce, cabbage.
  54. 54. FLOWER  Flower is the beautiful part of a plant that produces seeds or fruit.  Blooms from a bud.  Flowers can be of different size, shape, color and smell. Common flowers are: Rose, Lotus, Marigold, Jasmine, Sunflower ,Hibiscus  Some flowers smell good. Some of the good smelling flowers are rose, jasmine, lotus, sunflower, apple flower.  Butterflies and bees come to flower in search of nectar.  Flowers grows into fruit like cauliflower and broccoli and helps the plant to reproduce.
  55. 55. FRUITS  Fruit is the fleshy part of a plant that grows from flowers and have seeds inside them.  Fruits are juicy and tasty.  Some fruits are apple, orange, mango, watermelon and peach.  A fruit protects the seeds that are inside it. New plants grow from these seeds.  Fruits are very useful for us. They protect us from various diseases. We should eat plenty of fruits daily.
  56. 56. SEEDS  The hard part inside the fruit is called its seed.  A seed grows into a new plant.  Seeds have baby plants inside them.  We eat cereals like wheat and rice, pulses like gram and pea. These are seeds of some plants.  Most fruits have seeds inside them.  Some fruits have one big seed like mango and litchi. Some fruits have few seeds like apple and pear. Some fruits have many seeds like watermelon and papaya.  A seed needs air, water and sunlight to grow.  Seeds inside some fruits that we don’t eat are: Orange, Papaya, Watermelon , Mango ,Apple ,Musk Melon ,Chikoo or Sapodilla ,Apricot.  Some fruits whose seeds we eat are: Pomegranate, Fig, Banana, Strawberry, Kiwi, Guava, Raspberry, Grapes.  There are many other seeds that we use as food. Rice, Wheat, Dal, Almond, Pea, Peanut.
  57. 57. BUDS AND BRANCHES  Buds: Flowers bloom from tiny buds.  Branches: grow outwards from the stem and bear leaves.
  58. 58. SEED GERMINATION PROCESS: A baby plants needs food, air, water, and sunlight to grow. We sow seed in the soil. Roots absorb water and nutrients from soil. The seed gives food to the baby plant. The seed bursts open when the baby plant grows into a little plant. This little plant is called a seedling. After some time, the seedling grows into a new plant. This is how plants grow and change into a new plant.
  59. 59. PARTS OF THE PLANTS (ROOTS, LEAVES, STEMS, FLOWERS)
  60. 60. PARTS OF THE PLANTS (SEEDS)
  61. 61. USES OF PLANTS  As Food: - we eat different parts of plants. Leaves: Spinach and Tea plant. Stem: potato and sugarcane. Roots: radish and onions. Fruits and seeds: apple and rice.  Plants give us paper and wood: - Paper, Bat ,Spoons, Chopsticks ,Wooden Pencils ,Wooden Bed ,Wooden Door, Wooden Chair.  Plants are used in medicines: -Tulsi :Juice of Tulsi leaves is used for cough and cold. Turmeric : Turmeric is used in cooking and also as anti inflammatory . Aloe Vera; Juice of aloe Vera plant is good for skin. Amla: Amla juice is good for stomach.  Fibers : Clothes are made from cotton fiber and linen fiber Jute and coconut fibers are used to make ropes, mats etc. Cotton cloth Jute mats Coconut coir Rope theeducationdesk.com  Perfumes :Sweet smelling flowers like rose and jasmine are used to make perfumes. Rose Perfume Jasmine  Clean Air : Plants make the air clean and fresh. They give shadows. Plants also help to make the soil more nutrient.
  62. 62. CARE OF PLANTS  At home: Like human’s plants also need water, otherwise they may die. So water the plants regularly. Plants breathe through their leaves so clean the leaves regularly. Plants make their food and grow using the sunlight. So make sure plants get enough sunlight.  At public places: Take care of plants at public places like parks, gardens. Don’t walk on grass harshly. Don’t pluck leaves, Flowers and branches of trees. Do not scratch or write on tree trunks.
  63. 63. WHERE DO PLANTS GET THEIR FOOD FROM?  Plants are the only living things that can make their own food.  Plants can only make their food in the sunlight.  They use water from the soil and carbon dioxide from the air.  A plant makes its food in its leaves. In the sunshine, the water and carbon dioxide are combined in the green leaves, to make plant food. While this happens, the plant makes oxygen. This oxygen goes out into the air through the tiny holes on the leaves.  When you water a potted plant, the roots take up the water.  It is then carried by the stem to the leaves. The food made in the leaves is also carried through the stem to all parts of the plant.  Plants use the food they make.  They need it to live and grow. Any extra food is stored away. Human beings and animals use this stored food. Plants store their food in fruits, seeds, stems and some parts that grow below the ground.  When you water a potted plant, the roots take up the water.  It is then carried by the stem to the leaves. The food made in the leaves is also carried through the stem to all parts of the plant.
  64. 64. PLANTS MAKE THEIR OWN FOOD
  65. 65. HOW THE ROOTS TAKE UP THE WATER
  66. 66. HOW DO PLANTS HELP ANIMALS?  Plants provide food for animals. Many animals live on leaves and grass. These animals are called herbivores. Some animals eat other animals and they are called carnivores. Animals that eat both plants and animals are called omnivores.  Many animals make their homes in trees. Others live in the shade of plants. They may also hide themselves in the trees or in tall grass.
  67. 67. •Without sunlight and water the plant would die. When a potted plant was kept inside a closed box for some days what do you think would happen and why?
