Oct 31, 2023 · The xylem transports water and minerals to the leaves; the phloem transports the photosynthetic products to the other parts of the plant. Plants in cold climates have needle-like leaves that are reduced in size; plants in hot climates have succulent leaves that help to conserve water.

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 ...
Loading... Show transcript. Welcome to this lesson from the Unit: Cells. The lesson title is Plant cell structures and their functions. Today we're gonna be looking at those living building blocks that make up all living organisms called cells, and in this case, the cells that make up plants.
1. The plant’s vascular tissues—xylem and phloem—transport water to the leaves and carry glucose away from the leaves. Anyone who cares for plants could probably tell you that pouring water directly onto the leaves isn’t the best idea. Plants absorb water from the soil, using their roots.
