What is the function of the leaf in plant?
The function of a plant leaf is to provide a structure in which chloroplasts can be exposed to sunlight so that they can perform photosynthesis.
Decline of the plant, growth of another leaf, improvement in the plant, and propagation of another plant are possible outcomes when a leaf is cut off a weed. The consequence for the plant depends upon the function, health, location and size of the severed leaf and of the weed. The consequence for the leaf will be decline into death or, if proper procedure is followed, propagation of another plant.
Is the main function of a vein of a leaf is to transfer chloroplasts throughout the plant for maximum efficiency of photosynthesis?
How does the placement of veins help to carry out their function of transporting materials to and from the leaf.?
The monocot leaf has the same functions as any other leaf - the production of starches, sugars, and other carbohydrates needed by the plant. By promoting the growth of the apical meristem, it ensures the growth of the main stem of the plant. [A similar process promotes the cell growth at root tips.] Elevating the top of the plant aids survival.
The primary function of the leaf is to produce food for the plant. Plants make food through photosynthesis, a process in which chloroplasts convert sunlight into ATP which is energy for the plant. Logically, if a plant makes food for the plant it must have the tools to do so, which is why it has many chloroplasts for its food making processes.
