When a seed gets planted into the ground, it will go through a growing process called germination. Germination happens inside the seed, and with just the right combination of soil, water, and sunlight (warmth), the embryo will start to grow. Once the leaves grow, the plant will be ready to start making food on its own. plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cells grow, they also become specialized into different cell types through cellular differentiation.

- On the upper part of leaf there present number of small opening or pores called stomata.
- Stomata help in exchange of gases, which is intake of carbon dioxide and release of oxygen in the presence of water and sunlight by the process of photosynthesis.
- Plants prepare their food by photosynthesis.

• An object which gives out its own light is called a luminous object.
• When an object is placed in front of a source of light, it produces a shade behind it, called shadow.
• Those materials which allow electric current to pass through them are called conductors.
• Those materials which do not allow electric current to pass through them are called insulators.
• The changing of water into water vapour is called evaporation.
• The loss of water from plants as water vapour through the pores of their leaves is called transpiration.
• The changing of water vapour into liquid water on cooling is called condensation.
• The activity of collecting rainwater directly and store it in big tanks for later use, or making the rainwater percolate into ground more efficiently to recharge the ground water, is called rainwater harvesting.

Water is being continuously used and water conservation is the major concern in the present scenario. The water cycle has helped in maintaining water on the surface of the earth for millions of years. The water circulated in water cycle takes three different forms – solid, liquid and gaseous. The solid form of water – ice, is found at the poles of the earth, the snow covered mountains and the glaciers. The liquid form is present in the rivers, lakes, seas, and oceans. The gaseous form of water, water vapor is present all around us.

A compass can be used to find East-West direction at any place.
Always the needle of the compass points towards North-South direction. So if North-South direction is known then East-West direction can also be known.

Air is a mixture of gases, water vapour and dust particles. Some of the gases; present in air; are discussed below.
Nitrogen: Nitrogen is the largest component of air. Nitrogen makes up 79% of air around us. Nitrogen is used by plants to make protein. Plants cannot take nitrogen directly from the air. Some nitrogen fixing bacteria live in soil. They help in nitrogen fixation in soil. Thus, plants are able to take nitrogenous compounds from the soil.
Oxygen: Oxygen is the second largest component of air. Oxygen makes up 21% of the air around us. Oxygen is used by living beings for respiration. After respiration, the living beings produce carbon dioxide.
Carbon dioxide: The remaining 1% of air is composed of carbon dioxide, many other gases, water vapour and dust particles. Carbon dioxide is also important for living beings. Plant need carbon dioxide to make food during photosynthesis. During photosynthesis, plants take in carbon dioxide and release oxygen. Thus, green plants help in maintaining the balance of carbon dioxide and oxygen in atmosphere.

- The leaves of the desert plants are either absent or are very small or may be present in the form of spines to reduce the loss of water through transpiration.
- In desert plants, the spines or stems are modified to perform the function of photosynthesis.

Autotrophs are the organisms which exhibit autotrophic mode of nutrition. Autotrophs are organisms which can synthesise their own food by the process of photosynthesis. Plants and some bacteria that can synthesise their own food and are called as autotrophs.

The mountain habitat is very cold and snowfall takes place in winters in some areas.
The trees of the mountain habitat are cone-shaped. The leaves of such trees are needle-shaped. The needle-shape of leaves helps in preventing accumulation of snow on the leaves and thus they are not damaged due to snow.
Animals in the mountain habitat have thick coat of fur. This helps in keeping them warm during very cold winters. The mountain goats have strong hooves which help them in running along the mountain slopes. Yak and snow leopards are common examples of animals in the mountain habitat.

Recycling of Paper:
Recycling of paper is done by the following method:
- Take some old newspapers, magazines, used envelopes and notebooks or any other waste paper and tear them into small pieces and put them in a tub.
- Put some water into the tub so that the pieces of paper remain submerged in water for a day.
- Make a thick paste of paper by pounding it.
- Take a fine wire mesh fixed to a frame and spread the thick paste of paper on it.
- Pat it gently to obtain a uniformly thick layer of paper paste. Wait till all the water from paste drains off.
- A sheet of old cloth or a newspaper can be used to soak up extra water present in the layer of paper paste.
- Remove the layer of paper paste from the wire mesh carefully and spread it on a sheet of newspaper kept in the sunshine to remove all the water left in the layer of paper paste and make it completely dry.
- This dried and thin layer of paper paste is the recycled paper.

A snail propels itself by deforming a layer of mucus beneath it via muscular contractions in its foot muscle. This unique form of locomotion allows snails to traverse almost any obstacle, including the ability to climb steep inclines.
Thus, the locomotory organ in snail is the 'muscular foot'

- There are around 650 skeletal muscles in the human body.
- There are three types of muscle, skeletal, cardiac, and smooth.
- Skeletal muscles (or striated) are voluntary muscles that control nearly every action a person intentionally performs. Tendons attach the muscle to two bones across a joint, as one muscle contracts the other relaxes which moves the bones.
