Plants grow in many different shapes and sizes. Much of their shape depends on an internal structure that is composed of carbon-containing molecules such as cellulose and lignin. Plants that have a strong internal structure can grow larger than other plants because their structure can support their size. Plants obtain the majority of the carbon necessary for building these structural molecules from

Respuesta :

Carbon is very important to plants and they obtain the majority of it from the air in the form of carbon dioxide.

Uses of carbon dioxide in plants

  • To make food through the process of photosynthesis.
  • Source of carbon used in building structural molecules.

In conclusion, carbon is very important to plants as they both use it to get food and to maintain their shape owing to their internal structure being made from carbon.
