How Plants Convert Solar Energy into Chemical Energy

Photosynthesis is the process by which plants convert solar energy into chemical energy. The first step in photosynthesis is light absorption, which helps the plant digest carbon dioxide and produce oxygen. In this article, we’ll explore the various parts of a plant that help it carry out this process, including the chloroplasts and other organelles inside the cells, and even the cell walls themselves.


The chloroplast is a light-weight version of the cell, containing the organelles that carry out photosynthesis. Inside the chloroplast are some 40 different proteins that use sunlight to produce small molecules called organic acids. These acids in turn are used to create carbohydrates, which feed the cell and allow it to grow. In most plants, there are two types of chloroplasts in the mesophyll cells:

  • Chloroplasts which contain only a small set of proteins required for photosynthesis.
  • Chloroplasts which contain all the proteins needed for photosynthesis, as well as lots of additional proteins required for the growth and development of the plant.

The difference between the two is determined by the level of light in the plant’s environment. In general, plants in bright light have larger and more active chloroplasts than those in shady spots. This means that plants can take in more sunlight, and therefore, more carbon dioxide for photosynthesis.


The other important organelle involved in photosynthesis is the other part of the cell which contains all the proteins involved in the process: the organelles. These are the vacuoles, the endoplasmic reticulum, and the mitochondria. Together, these proteins create structures known as the thylakoids which turn sunlight into chemical energy that the plant can use.

Each of these organelles has its own functions in photosynthesis. The vacuoles store carbon dioxide and other nutrients for the plant. The endoplasmic reticulum helps create proteins and enzymes which allow the plant to transform nutrients into energy and substances the plant can use. Finally, the mitochondria create the chemical energy necessary for most living things, such as humans, to exist.

Plants can’t survive for very long without oxygen. Like other animals, they need this gas to breathe, and they need it quickly. The oxygen produced by the photosynthesis process diffuses to the surrounding environment through tiny pores on the surface of the plant cell. These areas are known as stomata, and they open and close in direct response to changing environmental conditions, allowing the plant to regulate its carbon dioxide levels. When oxygen is lacking in the environment, plants close their stomata to keep out this harmful gas. This is why it’s important to keep an eye out for signs of whether or not your plant is doing better. If it’s feeling a little chilly, it could be a sign that it needs some extra exposure to sunlight to keep its internal systems functioning properly.

Cell Wall

Finally, we come back to the cell wall, the colored outer layers of plant cells which protect them from the environment. When plants are still new to an area, they’ll often start out with thinner cell walls than usual to help them adjust to their new surroundings. As the plant gets used to its new location, its cell walls thicken to protect it from damage, especially from water loss.

When we think about how plants convert solar energy into chemical energy, it’s important to keep in mind that not all of them do this in the same way. Some do this by drawing heavily on the environment around them. For example, tropical plants which are already full-grown will tend to rely more on their surroundings than on light to produce their needed oxygen. They’ll also tend to draw heavily on the carbon dioxide they capture from the air to make carbohydrates which feed the cell and allow it to grow.

On the other hand, some plants, such as those which grow in the Northern regions, need more direct exposure to sunlight to carry out photosynthesis. The light from the sun encourages them to produce larger amounts of chloroplasts and other organelles in the mesophyll cells to help convert more sunlight into chemical energy.

Whether or not a plant is successful in this conversion is largely based on how well it can utilize the available sunlight in its environment. In general, plants need lots of good light to carry out photosynthesis successfully, so if there isn’t any available, they won’t be able to produce the chemical energy they need to live. This is why it’s important for them to be exposed to as much sunlight as possible throughout the year. Too much exposure to sunlight, however, can cause the plant to become overheated, which can damage it.

Final Takeaway

When we think about how plants work, we often think about what’s inside the cell. While it’s true that the cells contain all of the necessary materials to enable photosynthesis to happen, it’s also important to consider the role the cell wall plays in this process.

The cell wall not only keeps the cell components together, but it also provides a direct connection to the environment. It allows the plant to take in more sunlight and expel less oxygen into the air than it would if it didn’t have the cell wall, making it an important barrier for photosynthesis to happen.

Plants are essential to our environment. We can’t live without them, but we also can’t live with them if we want to continue breathing. It’s important to remember that plants are living things, too, and we need to be careful not to upset them or put them in danger by being too touchy-feely with our smartphones or other electric gadgets. This makes it all the more important to learn how to look after our plants successfully in the first place. This way, we’ll be able to enjoy their beauty for many years to come.
