It is perennial in hot climates , but generally grown as annual. I (the guard cell) regulate gaseous exchange between the plant and the environment. Broadly, plants have two organ systems: A) the root system and B) the shoot system. Taproot systems feature a larger, central root from which all the other smaller roots in the system arise. These genes, in addition to others, are responsible for the formation of carotenoids in organs and structures. The xylem is in the center of the vein with the phloem distributed on both the adaxial and abaxial sides of the bundle (Hayward 1938). Sunmmary. These are berries normally with two boxes, sometimes three or more, with very many seeds. A compound leaf is made up of leaflets which are distributed along the leaf rachis. Their corolla has five bright yellow petals, fused at the base, often reflected backwards, forming a five-pointed star. Palisade mesophyll is composed of oblong, upright parenchyma cells. For example, the Lcy-e gene is highly expressed in leaves, which results in the production of the carotenoid lutein. The midvein runs through the midrib and is the main vascular bundle in the leaf. A few plant cells help in the transport of water and nutrients from the roots and leaves to different parts of the plants. Spongy mesophyll consists of more irregularly shaped parenchyma cells arranged in a loose structure. The neighbouring cell I would be communicating with is the epidermal cell.
