The function of a leaf is photosynthesis - to absorb light and carbon dioxide to produce glucose (food). The equation for photosynthesis is: \ (\text {carbon dioxide and water} \rightarrow...

Oct 31, 2023 · Similar to the stem, the leaf contains vascular bundles composed of xylem and phloem. The xylem consists of tracheids and vessels, which transport water and minerals to the leaves. The phloem transports the photosynthetic products from the leaf to the other parts of the plant.
Dec 11, 2015 · Usually a single layer of tightly-packed cells, the epidermis mediates exchanges between the plant and its environment, limiting water loss, controlling gas exchange, transmitting sunlight for photosynthesis, and discouraging herbivores. The epidermis secretes a waxy cuticle of suberin, which restricts evaporation of water from the leaf tissue.

It is the waxy layer of the leaf secreted by the epidermis, a thin layer of leaf present just below the cuticle. It performs the following functions: 1. Preventing excessive water loss from the leaves through transpiration 2. Controlling the exchange of gases such as dioxide and oxygen from the leaf surface Giving mechanical support and thus preven...
It is a thin layer of cells below the cuticle. Mostly they are devoid of chloroplasts and thus do not perform photosynthesis. The upper epidermis performs the following functions: 1. Preventing excessive water loss from the leaves through transpiration 2. Allowing sunlight to pass through the spaces between the cells and thus helping to initiate ph...
It is found just below the upper epidermis and is thus also called the upper leaf cells. They consist of columnar cells arranged vertically beside each other, much like the columns of a building. The columnar cells are tightly packed to maximize the absorption of sunlight. Sometimes it can consist of several layers of cells, particularly in environ...
This layer is found below the palisade layer. Also called the lower leaf cells, the spongy layer consists of irregularly shaped cells consisting of the vascular tissues – xylemand phloem, forming the vascular bundles. The vascular tissues are surrounded by parenchymal pith and collenchymas. The cells contain minute pores called stomata (Singular: s...
It is located on the bottom side of the leaves below the spongy mesophyll layer of cells. Stomata are essential structures in the lower epidermis. There may be up to one million stomata per square centimeter. Each stoma is flanked by kidney-shaped epidermal cells called guard cells. The guard cells control the opening and closing of stoma based on ...
Recognize the internal cellular structure of leaves. Describe how the structure facilitates photosynthesis. Describe how the structure facilitates gas exchange. Explain why leaves in autumn turn from green to yellow, orange, and red.
Leaves produce food for the plant through a process called photosynthesis. The leaves of different plants vary widely in size, shape and colour and are adapted to carry out photosynthesis.
