In many other plants the cotyledons are relatively small, and the embryo is nourished by a tissue called endosperm. 62 C hapter 5 Uses of Plants H uman beings depend on plants. Directly or indirectly, plants provide food, clothing, fuel, shelter, and many other necessities of life. Humankind’s dependence on crops such as wheat and corn (maize) is obvious, but without grass and grain the livestock that provide people with food and other animal products could not survive either. Food The food that plants store for their own growth is also the food that humans and other organisms need to live.

After four months, a single rye plant, for example, has about 13,800,000 roots. If the epidermis of those roots was spread out flat, it would cover a football field. Flowers and Fruits Flowers are the primary reproductive organs of those plants belonging to the division Anthophyta. The flowers are where the seeds that will give rise to new plants are produced. The primary parts of the flower are the sepals, petals, stamens, and pistil. The leaflike sepals form the protective covering for the flower bud before it opens.

Most photosynthesis takes place in the mesophyll. Mesophyll cells form a loose network with many gaps, allowing carbon dioxide and water vapor to move freely among the cells. 5 square centimeters) of an elm leaf may have 250 million chloroplasts, and a mature elm tree may have 100,000 leaves. The veins of the leaves contain the transport tissues—xylem and phloem. Xylem brings water and mineral nutrients such as nitrogen to the mesophyll cells. Phloem transports sugars and organic matter from the mesophyll cells to other parts of the plant.
