What Do Plants Need To Grow?

All plants need four things to grow: sunlight, water, air, and nutrients from the soil.


Sunlight is necessary for the plant to create its own food through photosynthesis. Another reason is that light helps plants regulate their growth and development. For example, plants use light to produce certain hormones that control things like flowering and fruit production.

When choosing where to place your plant, look for a place that gets a lot of sunlight.

Light is energy, and it’s important for photosynthesis (the chemical reaction which produces energy for plants to survive) to occur. During this process, plants use light to create food from carbon dioxide and water, and oxygen is released as a byproduct. If there isn’t enough light (or if the light is the wrong kind of light), this process won’t happen, and the plant will starve to death.


Water is essential for plant growth. Plants need water to absorb nutrients from the soil, transport these nutrients throughout the plant, and support the plant structure. Water also helps to regulate plant temperature and provides plants with the necessary moisture for photosynthesis.


Air is necessary for the plant to breathe and to exchange gases with the surrounding environment.

They need it for photosynthesis, which is how they convert sunlight into energy, and they also need air for respiration, which is how they convert the energy from photosynthesis into food.

Without air, plants would not be able to grow. They would not be able to convert sunlight into energy, and they would not be able to convert that energy into food.

Additionally, they would not be able to transport water and nutrients from the roots to the rest of the plant. All of these things are essential for plant growth, so air is essential for plants.


Nutrients from the soil are necessary for the plant to grow and to create its own food.

All plants need nutrients to grow. They are necessary for the production of chlorophyll, the pigment that gives plants their green colour. Chlorophyll is essential for photosynthesis, the process that plants use to convert sunlight into energy.

Nutrients are also necessary for the production of other plant hormones, enzymes, and proteins. They are needed for root growth, flowering, and fruit production. Without nutrients, plants would not be able to grow, reproduce, or survive.

An introduction to photosynthesis

Photosynthesis is the chemical process by which plants produce sugar and starch from carbon dioxide and water using the energy from light. The sugar and starch is then stored in the plant’s roots and branches. Oxygen is a by-product of photosynthesis and is released during respiration, which is the release of gas from the plant and back into the air. Respiration is necessary for plants to release the oxygen they produce during photosynthesis.
