Internal Leaf Parts & Function
Lower epidermis - outmost tissue on the lower side of the leaf; protects the leaf
Upper epidermis - outmost tissue on the upper side of the leaf; protects the leaf
Palisade layer - rows of elongated cells in the upper center of leaf; site of photosynthesis
Cuticle - waxy layer on the covering the epidermis; holds in moisture, prevents too much absorption of water
Stoma - opening between the guard cells; allows for gas exchange and some water
Guard cells - surround the stoma; control the opening and closing of the stoma
Vein - supply support for the leaf; contain the xylem and the phloem
Spongy layer - irregular shaped cells in lower center of leaf; absorbs gas & some water
Air space - space in the spongy layer; contain gases
Xylem - found in the vein; transports minerals and water from roots to shoots
Phloem - found in the vein; transports sugar & other products of photosynthesis from leaves to other parts of the plant
Chloroplast - cells in the leaves that contain chlorophyll; trap light energy and convert it to chemical energy
Mesophyll - all of the middle tissue of the leaf

The blade of the leaf is responsible for photosynthesis, where sunlight is converted into energy for the plant. The veins transport water and nutrients throughout the leaf. The stomata regulate gas exchange, allowing for the intake of carbon dioxide and the release of oxygen.

∙ 14y agoCells are the basic structural and physiological units of plants. Most plant reactions (cell division, photosynthesis, respiration, etc.) occur at the cellular level. Plant tissues (meristems, xylem, phloem, etc.) are large, organized groups of similar cells that work together to perform a specific function. A unique feature of plant cells is that they are readily totipotent. In other words, almost all plant cells retain all of the genetic information (encoded in DNA) necessary to develop into a complete plant. This characteristic is the main reason that vegetative (asexual) reproduction works. For example, the cells of a small leaf cutting from an African violet have all of the genetic information necessary to generate a root system, stems, more leaves, and ultimately flowers. Specialized groups of cells called meristems are a plant's growing points. Meristems are the site of rapid, almost continuous cell division. These cells either continue to divide or begin to differentiate into other tissues and organs. How they divide, and whether they ultimately become a tissue or an organ, are controlled by a complex array of internal plant hormones but also can be influenced by environmental conditions. In many cases, you can manipulate meristems to make a plant do something you want, such as change its growth pattern, flower, alter its branching habit, or produce vegetative growth.

∙ 12y agoA leaf has petiole, lamina, apex and margins.
The true leaf must have an axillary bud. Sometimes cladode & phylloclade also look like leaf but these are without an axillary bud hence not true leaf. Functions of laf include- photosynthesis, transpiration and several other functions in modified leaves such as climbing by tendrils made out of leaf lamina and spines for protection etc.

The external leaf structure serves to protect the internal tissues of the leaf, regulate gas exchange through tiny openings called stomata, and capture sunlight for photosynthesis through chlorophyll-containing cells.
A leaf functions as a tissue in a plant, specifically as part of the plant's organ system for photosynthesis. The leaf contains chlorophyll, which absorbs sunlight and utilizes it to convert carbon dioxide and water into glucose, the plant's food source.
The stalk that joins the leaf blade to the stem is called the petiole. Its primary function is to support the leaf and connect it to the rest of the plant's vascular system for the transport of nutrients and water.
The outer layer of the leaf is called the cuticle. Its functions include reducing water loss through evaporation, protecting the leaf from pathogens and herbivores, and serving as a barrier against harmful UV radiation.
A compound leaf is a leaf structure where the leaf blade is divided into multiple leaflets attached to a single leaf stem, called a rachis. Each leaflet may resemble a small, individual leaf but is part of a larger compound leaf structure.

The external leaf structure serves to protect the internal tissues of the leaf, regulate gas exchange through tiny openings called stomata, and capture sunlight for photosynthesis through chlorophyll-containing cells.
The outer part of the leaf is called the cuticle. It is a waxy layer and does not comprise of live cells. It's function is to prevent the leaf from desiccation (drying out).
The function of the leaf blade is to abosorb light and make food.
The function of the veins in a leaf is to transport food to different parts of the leaf
Leaf called the jack of all trades because it can perform all the function in plants. Leaf produces food,stores it, and transport it to the other part of the plant.

Leaf is part of a plant. Leaflet is part of a compound leaf.
Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
it is to carry meth into the leaf through the veins into the petiole and ending up in the roots. This makes the plant very high.
