Photosynthesis is the process by which plants convert water, and carbon dioxide into glucose and oxygen by fixing or absorbing sunlight. During photosynthesis, plants use chlorophyll in their leaves to capture solar energy, which is then used to convert water and carbon dioxide into glucose. This process is essential for plants to produce their own food and release oxygen into the atmosphere. Transpiration is the process of water movement through a plant. Translocation refers to the movement of sugars and other nutrients within a plant. Perspiration is the process of sweating in animals.

Convex mirrors are used for side view in vehicles because they have a wider field of view and provide a larger image compared to concave mirrors. This allows the driver to see a larger area and objects that may be in their blind spot. The convex shape of the mirror causes light rays to diverge, resulting in a wider view. Additionally, convex mirrors also help to reduce the distortion of the image, making it easier for the driver to judge the distance and size of objects.

The SI unit of speed is meters per second (m/s). This unit represents the distance traveled in meters divided by the time elapsed in seconds. Meters per second (m/s) is commonly used in scientific and engineering calculations to measure the rate at which an object or person is moving. The m/s unit allows for precise and consistent measurements, making it the standard unit for speed in the International System of Units (SI).

A thermometer is used to check the temperature. It is a device that measures the temperature of a substance or an environment. It consists of a glass tube filled with a liquid, usually mercury or alcohol, that expands or contracts with temperature changes. The expansion or contraction of the liquid is indicated by a scale on the thermometer, allowing the user to read the temperature. Thermometers are commonly used in various settings, such as in homes, laboratories, and medical facilities, to monitor and control temperature.
