Where Does Grass Get Its Energy From?

February 15, 2024

As soon as the weather warms up lawn mowers start to come out, but did you ever wonder where does grass get its energy from? Grass gets its color from a pigment called Chlorophyll, it is this pigment that allows plants to capture the Sun’s energy through photosynthesis. The chlorophyll molecule absorbs the light of two different wavelengths, red and blue, while reflecting green. Without Chlorophyll, the only thing your lawn would be is a dead, brown mess.

During the process of photosynthesis, a plant turns water and carbon dioxide gas into sugar (glucose) for growth while it releases oxygen into the atmosphere as a by-product. Grass uses sunlight and water from its roots to produce this glucose, which is used by the grass plant for growth and development. The same process also provides the food for other living organisms, including humans.

Like all other plants, grass catches its energy from the sun through a process known as photosynthesis. It absorbs water and carbon dioxide from the air through small pores in the leaves called stomata, where it changes to a liquid state and is absorbed by the leaf tissue. The stomata close and open as needed depending on the weather conditions.

When the stomata are open they allow carbon dioxide in to be exchanged with the atmosphere and water out into the soil. When it isn’t raining the stomata are closed so that the grass can conserve its water. The excess carbohydrates are stored away as reserves to be used when the grass is stressed by weather or when its energy levels begin to run low, which is why it’s important to apply lawn feed to keep your lawn looking healthy all year round.
