*Why do plants drop their leaves?

*A plant is full of vascular cells that transport water and sap throughout, from root to leaf tip. As the amount of sunlight decreases in autumn, the veins that transport sap into and out of a leaf slowly close off. Then a layer of cells, called the separation or abscission layer, develops at the base of the leaf’s stem. When this layer is completely formed, the leaf falls off.

* What are different ways of dispersal?

Why do plants make food?Plants make food the same reason humans make food to survive without the essentials they wouldn’t be able to make food – The things that plants cannot live without are water, carbon dioxide from the air, sunlight, and nutrients in the ground! Plants use these things in a special process called “photosynthesis” which allows them to make their own food,

* What does the word pollination mean?

*Pollination is when pollen is transferred from the anther to the stigma of a plant

* What's the process of photosynthesis?

*Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis.
