  There are thousands of different kinds of microbes. Microbes called bacteria are the smallest living things. Bacteria live almost everywhere: on land, in water, and even inside you. Some microscopic life forms are like plants. Tiny diatoms are microbes that live in lakes and the ocean. Diatoms soak up sunlight and use its energy to make food, just like plants.

  Some microscopic life forms are more like animals. Protozoa such as the amoeba and paramecium are animal-like microorganisms. An amoeba can move by changing the shape of its body. It sticks out a pseudo pod, or false foot. A paramecium is covered with tiny hairs. It waves its hairs rapidly to swim.

  Viruses are another kind of microbe. Viruses sometimes act like living things and other times act like nonliving things. Viruses sometimes live in the cells of plants and animals. Inside a cell, a virus reproduces like a living thing. The virus uses the cell to make many copies of itself. Viruses are too small to see with an ordinary microscope. You need a powerful electron microscope to see a virus. Outside of a plant or animal cell, a virus is like a nonliving thing.

 

What helps a paramecium swim?

   Andrew is an Indian farmer. He gets ___________ (6) early in the morning. It is quite true to say that an Indian farmer sleeps with the lamb and rises with the lark. Then he goes with ___________ (7) buffalo to the field. The day’s work begins. Slowly the sun ___________ (8) and climbs into the sky. But the heat of the sun cannot drive him away from work. Our tropical sun shows no mercy to the Indian famer even then the latter does not brother about sun and shower.

   He ___________ (9) rest for a short while under a shady tree. Then once again he starts his work of ploughing, or harrowing the clods or sowing seeds and leveling the field with the help of the leveler. Or, ___________ (10) the crops are already a few inches high, he may be seen watering the fields or weeding out wild plants. All days, in the life of an India farmer, are alike but a day in the harvesting season is a day of joy in his dull life. It is a day when the Indian farmer reaps the fruits of his labour.

Read the passage below and decide whether the statements are TRUE or FALSE?

   Animals live everywhere. They roam the land. They burrow in the ground. They swim in the sea. They fly through the air. They creep, they leap, they soar, and they dive. A very few – including corals and barnacles – stay in one place.

   Animals come in all sizes. The biggest animals are whales, which can be 100 feet (30 meters) long. The smallest animals can only be seen through a microscope. Zoologists (scientists who study animals) have found more than 2 million species (kinds) of animals. They think they have discovered only a small portion of all animals on Earth.

   Several things make animals different from other living things. Unlike plants, animals cannot make their own food. Animals eat other living things–plants and other animals–to get energy. Animal bodies are made up of more than one cell, unlike bacteria and other life forms with only one cell. Cells are the building blocks of living things. Animals also have senses, such as eyes or ears, that tell them what is going on around them.

We can find animals in almost everywhere from the land to the sea.
