Leaves are the main photosynthetic organs of plants. They are responsible for capturing light energy and converting it into chemical energy through the process of photosynthesis. Leaves come in various shapes and sizes and are adapted to perform different functions based on the plant'senvironment and needs.
Structure of a Leaf
A typical leaf has the following parts:
Blade: The broad, flat part of the leaf where most of the photosynthesis takes place.
Petiole: The stalk that attaches the leaf to the stem of the plant.
