Plants

Plants play an important role in nature. They can live on land as well as in water. Plants are extremely beneficial to us, as they provide us with a variety of products such as food, wood, and paper. The majority of our food comes from plants, such as fruits, vegetables, cereals, and pulses. We eat plant roots, leaves, stems, flowers, and fruits.

Roots

Roots are found beneath the soil’s surface and keep the plant firmly in place. The primary function of this organ is to absorb water and nutrients for the plant. It serves to store food and nutrients while also providing support to the plant. Many plants, such as beets, radishes, and carrots, have edible roots.

Stem

The stem can be green or brown, thin or thick. It maintains the plant’s upright position. It transports water and minerals from the roots to the leaves and food down the plant to be distributed and stored. It holds the branches, leaves, flowers, and fruits in place and connects them to the roots. Many plant stems, such as potatoes and ginger, are consumed as food. Mushrooms and other non-green plants do not prepare their food. Many plants, such as spinach, lettuce, and cabbage, have edible leaves.

Flowers

Flowers are the most visually appealing part of a plant. Each flower type has a unique physical structure, colour, and scent when compared to other flower type plants. Petals and the smell of the flower attract insects and bees, which pollinate the flower. Perfumes are made from the petals of sweet-smelling flowers. Flowers are commonly used for decoration and garlands. Lotus, rose, marigold, jasmine, sunflower, hibiscus, and other common flowers Broccoli and cauliflower are edible flowers.

Fruits

The fruit is a fleshy or dry ripened plant part that contains the seed or seeds. We eat oranges, mangoes, apples, grapes, and other fruits.

Seeds

The seed is the hard part inside the fruit. The majority of plants grow from seeds. Pomegranate, banana, fig, guava, kiwi, grapes, and other fruits have seeds that we eat. We don’t eat the seeds of apples, chikoos, and a variety of other fruits.

Plant Requirements

Plants are living organisms that require food to grow. Plants cook their own food. Plants require the following ingredients to produce food:

Sunlight – Plant leaves absorb sunlight as the plant requires. Some plants require more sunlight than others. Some plants require shade because they require only a small amount of sunlight.

Adequate water – Adequate water is required for healthy plant growth. Plants will suffer if they receive too much or too little water, and they may die. Water is absorbed by the plant’s roots. The amount of water required by each type of plant varies.

Adequate air and temperature – During photosynthesis, plants take in carbon dioxide through their leaves and expel oxygen. To help sustain their structural components, the plants should be in areas with little wind.

Rich soil – Plants obtain the nutrients or minerals they require from the soil in which they are planted. These elements are absorbed by the roots.

Space – Plants require adequate space to grow and expand their roots, which bind them to the ground. Plants that are overcrowded are more likely to die.

Animals

When we look around us, we notice various types of animals. Animals can be found all over the globe. They differ in size, shape, colour, and the types of environments in which they live. Animals are living beings who require food, water, and shelter in order to survive.

Animal classifications include:

Wild Animals – A wild animal is an animal that lives in nature or the forest (without man-made shelter) and must obtain its own food and water. Some of the wild animals are on display at the zoo. Wild animals can be vicious and dangerous. The lion is known as the “King of the Jungle.” Foxes, deer, lions, bears, giraffes, and other animals are examples.

Domestic animal – Domestic animals are animals that rely on humans for shelter, food, water, and general care. House cats, dogs, parakeets, a cow, horse, sheep, pig, and other animals are examples.

Pet animal – Pet animals are domestic animals kept for companionship and entertainment. Pet animals include dogs, cats, parrots, and mynas, among others.

Farm animal – Farm animals are animals that are raised for a specific purpose, such as meat, milk, hair, or something else. Sheep, goats, cows, and buffalo are some examples.

Note: – The situation determines whether an animal is domestic or wild. People domesticate horses, so they are domestic animals, but horses can also be found in the wild, so they are wild animals.

Land animals – Land animals are animals that live almost entirely on land. Peacock, horse, rhinoceros, elephant, giraffe, buffalo, and other animals are examples.

Water animals – Water animals are animals that live in bodies of water. They breathe in water through specialized organs called gills or directly through their skin. Examples include whales, sharks, dolphins, seahorses, octopuses, and fish.

Birds: Birds are animals with feathers, wings, two legs, and a beak without teeth. The majority of birds fly, but some can also swim in the water. Consider the duck.

Insects: Insects are animals that have six legs and usually one or two pairs of wings. Insects are the most numerous animal group. Ladybirds, cockroaches, houseflies, butterflies, grasshoppers, and other insects are examples.

How can animals help us?

  • Animals help us in a variety of ways.
  • Ploughing the field is done with a variety of animals, including ox and bullock.
  • Donkeys, camels, and other animals are commonly used to transport goods from one location to another, particularly in villages.
  • Milk is provided by animals such as cows, buffalos, and goats.
  • We get eggs from chickens and ducks.
  • Sheep are raised for wool, and silkworms are raised for silk. Wool is used to make the clothes we wear. Silk is also used to make clothing.
  • Animals such as dogs guard our homes and make excellent companions for humans.
