What are the 2 main jobs of leaves?

Answer 1

One main function of leaves are that they are where photosynthesis occurs, specifically in the mesophyll between the upper and lower epidermis layers. The mesophyll contains chloroplasts, which contain chlorophyll and are responsible for photosynthesis. They capture light energy from the sun, and through the process of photosynthesis then convert it into sugar molecules. Much of the energy required by living organisms relies on photosynthesis so this is a very important function. Leaves in fact are even able to twist in order to maximize sun exposure, and leaf surfaces have a wide, flattened shape thus increasing the surface area for effective light absorption.

Another main function of leaves are that they help the plant to conserve water and prevent the plant from drying up and dying. Plants have the ability to close the pores in their leaves. These pores, called stomata, react to chemical changes (like changes in weather or light), and are controlled by the surrounding guard cells. Environmental conditions that would cause plants to lose a lot of water (low humidity, high temperatures) stimulate guard cells to close, thus preventing water from escaping through the stomata.

Answer 2

To hold the flower's food. Basically the flower's fridge.

Answer 3

the function of leaf is to generate food for plant .

Answer 4

1.Photosynthesis (contain most of the chlorophyll in the plant).

2. structure of leaf (surface area) increases efficiency of water, Co2, O2 transportation
