Introduction

Water is an essential resource for both plants and animals. It plays a vital role in various metabolic processes and is necessary for the survival of living organisms on earth. In this article, we will discuss how plants and animals use water and why it is essential for their survival.

How plants use water

Plants absorb water through their roots and transport it to different parts of the plant. The water is used for various purposes, such as photosynthesis, transpiration, and maintaining turgor pressure in plant cells. Photosynthesis is the process by which plants use water, carbon dioxide and sunlight to produce glucose, which is the primary source of energy for the plant.

Transpiration is the process by which plants release water vapor into the atmosphere through tiny pores in their leaves called stomata. This process helps cool the plant and maintains the water balance in the plant.

Water also helps maintain the turgor pressure in plant cells, which is necessary for maintaining the structure of the plant. Turgor pressure is the pressure exerted by the fluid inside the plant cell against the cell wall. When there is enough water in the plant, the cell wall becomes stiff and the plant stands upright.

How animals use water

Water is essential for animals to survive. They use water for various purposes, such as digestion, maintaining body temperature, and transporting nutrients and oxygen to different parts of the body.

Digestion: Water is necessary for the digestion of food. It helps break down the food and aids in the absorption of nutrients in the digestive system.

Maintaining body temperature: Water helps regulate body temperature by sweat evaporation. When an animal sweats, water is evaporated from its surface, which helps cool the body.

Transporting nutrients and oxygen: Water is a vital component of blood, which transports nutrients and oxygen to different parts of the body. Water helps dissolve nutrients and oxygen, allowing them to be transported efficiently.

Conclusion

Water is an essential resource for both plants and animals. It plays a crucial role in various metabolic processes and is necessary for the survival of living organisms on earth. Therefore, it is necessary to conserve and protect water resources to ensure the survival of plants and animals and to maintain the ecological balance on earth.
