👉 Grammatophora are microscopic, single-celled organisms that inhabit plant cells and play a crucial role in the development of plants. They are known for their unique morphology, which includes the presence of specialized structures such as exoskeletons called stipes, which provide support to the cell wall. Their primary function is to help in the photosynthesis process by breaking down complex carbohydrates into simpler sugars that can be utilized by plants.
