2. Identify and describe modification of roots, stems and leaves of different plants. Give one example of each.
A bulb is a stem modification where leaf bases grow to form an underground food storage organ. An example of this is onions. Tubers are root modifications where underground stems are food storage organs. An example of a tuber is a potato. Storage roots are modified tap roots where swollen roots are used as food storage organs. Carrots have storage roots. Tendrils are leaf modifications where narrow outgrowths from leaves rotate through the air until they touch a solid support, to which they attach. Tendrils allows plants to climb. Sweat peas and mandevilla have tendrils.
