Read the following statements about a leaf. Which amongst them are correct? I. The swollen leaf-base mainly seen in leguminous plants is called the pulvinus. II. The axillary bud arises from the axil formed by the leaf. III. The leaf lamina is generally flat but may vary in shape and size from plant to plant.

Step-by-step solution

The leaf is the main photosynthetic organ of the plant. It majorly consists of the leaf base, petiole, and the leaf lamina. Sometimes the swollen leaf base, called pulvinus, is seen in leguminous plants. The leaf generally emerges from the node of the stem where it forms an axil through which an axillary bud emerges. This axillary bud further develops into a branch. The leaf lamina serves as the stage for harvesting light for photosynthesis. The shape of the leaf may vary from plant to plant
