This page is about Science Olympiad, and it contains information on Science Class 2 Chapter 1: Animals and Plants. Animals and Plants, Chapter 1 of the Science Olympiad, is critical for students preparing for NSO. Let’s take a look at the chapter’s extensive notes.
Science Class 2 Chapter 1: Animals and Plants
The most aesthetically attractive component of a plant is its flowers. When compared to other flower type plants, each flower type has a distinct physical structure, color, and fragrance. The flower’s petals as well as scent attract insects and bees, who pollinate it. Perfumes are created from the petals of fragrant flowers. Flowers are widely used for garlands and decorating. Common flowers include the lotus, rose, marigold, jasmine, sunflower, hibiscus, as well as others. Broccoli and cauliflower are examples of edible flowers.
Green or brown, slender or broad, the stem might be green or brown. It helps to keep the plant erect. The stem transfers water, nutrients, and nutrients from roots of plants, where they are dispersed and stored. It secures and binds the branches, leaves, blossoms, and fruits to the base. Many vegetable stems, including such potatoes and ginger, are eaten. The leaves of many plants, including spinach as well as lettuce, are edible.
The fruit is a squishy or watery plant component containing the seed or seeds. Therefore, oranges, mangoes, apples, grapes, and other fruits are consumed.
The seed is the toughest portion of the fruit. The vast majority of plants are born from seeds accordingly. Pomegranate, banana, fig, guava, kiwi, grapes, and other fruits contain edible seeds. However, we don’t consume the seeds of apples, chikoos, and other fruits.
Roots are situated under the soil’s layer and help to hold the crop in situ. This organ’s principal job is to absorb the nutrients for the crop. Its purpose is to store food and nutrients all while supporting the plants. Several plants have nutritious roots, including beets, radishes, as well as carrots.
Plants are extremely vital in nature. They may survive both on land and in water. Plants are incredibly valuable to humans since they supply a range of things such as food, timber, and paper. Plants provide the majority of our food, including fruits, vegetables, grains, and pulses. Plant roots, leaves, stalks, flowers, and fruits are all consumed.
A wild animal is one that lives in the wild (without man-made shelter) and must forage for its own food as well as water. The zoo has several wild creatures on display. However, wild animals may be deadly and nasty. The lion is referred to as the “King of the Jungle.” Examples include foxes, deer, lions, bears, giraffes, as well as other creatures.
Land animals are creatures that spend practically all of their time on land. Examples include the peacock, mare, rhino, elephant, gazelles, buffalo, and other animals.
Animals that dwell in bodies of water are known as water animals. They take in water via specialized organs known as gills or directly through their skin. Sharks, eels, whales, echinoderms, squid, and fish are among examples accordingly.
Insects are six-legged creatures with one or two sets of wings. The most multiple animal category is insects. Examples include ladybirds, roaches, flying insects, caterpillars, locusts, and other insects.
Pet animals are domestic animals that are kept both company and for amusement. These creatures comprise, among many other things, cats, rabbits, parrots, as well as dogs.
Domestic animals are those that rely on people for housing, food, water, and general care. Examples include house cats, dogs, parakeets, a cow, horse, sheep, pig, as well as other animals.
Birds are creatures having feathers, wings, two legs, and a toothless beak. The overwhelming majority of birds fly, but some can also swim. Think about the duck.
Farm animals are kept for just a specific reason, such as food, milking, fur, or anything else. Some examples are sheep, lambs, cattle, and buffalo.
It is important to note that the context decides whether an animal is domestic or wild. Horses are domesticated by humans, therefore they are domestic animals; nevertheless, horses may be found in the wild, since they are wild creatures.
