Leaf Blade: Wide flattened area of leaf for concentrating sunlight on photosynthetic cells. It is the primary function of green leaves. Leaf definition is - a lateral outgrowth from a plant stem that is typically a flattened expanded variably shaped greenish organ, constitutes a unit of the foliage, and functions primarily in food manufacture by photosynthesis. This process allows the plant to absorb water and minerals from the soil and conduct the same to the top of the plant. The process is called photosyn­thesis by which leaf manufactures food material in the presence of sunlight and green pigment- chlorophyll present in the leaf. The main function of leaf is photosynthesis. MBD Alchemie presents a 2D video for Science which is appropriate for Grade 3. Typically it is a thin expanded green structure which bears a bud in its axil. A leaf cell, by definition, is any cell found within a leaf.However, there are many different kinds of leaf cell, and each plays an integral role in the overall function of the leaf and the plant itself.
