Answer:
Plants can only grow under certain environmental conditions. They need three essential things to survive: sunlight, water, and nutrients. If a plant does not have these three elements, it will surely die.
A plant that has been deprived of water will lose its leaves. Adequate water is essential for plants to carry out vital processes such as photosynthesis, nutrient uptake, and maintaining turgidity in plant cells.
A plant that is deprived of light will turn pale or yellow. Light is necessary for photosynthesis, the process by which plants convert light energy into chemical energy, producing glucose (food) for growth and development. Without sufficient light, plants are unable to produce enough energy to sustain their metabolic processes.
To stay healthy, a plant needs to take in carbon dioxide (CO2) from the air and use water and nutrients to create food through photosynthesis. Carbon dioxide is absorbed through small openings called stomata on the surface of leaves.
By combining carbon dioxide, water, and light energy from the sun, plants convert them into glucose (food) and release oxygen as a byproduct in the process. This glucose provides energy and serves as a building block for plant growth, development, and reproduction.
In summary, plants require the right conditions, including sunlight, water, and nutrients, to survive and thrive. These essential elements enable them to carry out photosynthesis and produce the energy and food they need to stay healthy and grow.
