Just like different organs within the body, plant cell structure includes various components known as cell organelles that perform different functions to sustain itself. ADVERTISEMENTS: In this article we will discuss about the structure of a leaf with the help of a diagram. The diagram below represents one Elodea leaf cell in its normal freshwater environment. These organelles include: Cell Wall. Upper Epidermis: this is the tissue on the upper surface of the leaf. Leaf tissues are composed of layers of plant cells. The cell being the smallest unit of life, is akin to a tiny room which houses several organs. Leaves are responsible for converting sunlight and carbon dioxide into glucose, which is used to provide energy to the plant.. Leaves are classified into mainly two types based on their structure, dorsiventral, and isobilateral. These tissues include a mesophyll tissue layer that is sandwiched between two layers of epidermis. Leaf vascular tissue is located within the mesophyll layer. The first is to expose a maximum photosynthetic surface to sunlight; the second is to conserve … It is a rigid layer which is composed of … https://courses.lumenlearning.com/boundless-biology/chapter/leaves Like any other multicellular living thing, leaf structure is made up of layers of cells. The leaf is the organ in a plant specially adapted for photosynthesis. The maximum voltage at the pack is 2×4.2×48 = 403V, though it is widely known that the Leaf only uses about 80% of the pack’s capacity (20 kWh out of the 24 kWh to preserve cycle life) making the maximum cell voltage closer to 4.0V, and the pack’s maximum voltage closer to 384V. Show with another labelled arrow the direction the energy comes from. 36.Elodea is a plant that lives in freshwater. Using a microscope, it's possible to view and identify these cells and how they are arranged (epidermal cells, spongy cells etc). Different plant cell types form three main tissues found in leaves. A Labeled Diagram of the Plant Cell and Functions of its Organelles We are aware that all life stems from a single cell, and that the cell is the most basic unit of all living organisms. Anatomy of leaf is the detailed study of internal structure of a leaf, usually revealed by its dissection. Leaves are the main photosynthetic organs of the plant. By means of labelled arrows drawn on the diagram above, show the pathway taken by each of the two raw materials to a cell in the centre of the leaf. Viewing the leaf under the microscope shows different types of cells that serve various functions. A leaf is a compromise between two conflicting evolutionary pressures. Leaf Cross Section Showing Tissues and Cells. Evelyn Bailey. You need to understand the structure of the tissues in a leaf together with their functions. Give "one word names" for the processes by which these raw materials move across the leaf, as seen in the diagram. A leaf cell, by definition, is any cell found within a leaf.However, there are many different kinds of leaf cell, and each plays an integral role in the overall function of the leaf and the plant itself.
