The word “aerial” refers to as anything that exists in the air or in the space above a solid surface. The aerial part of plants simply denotes the structures of a plant that are above ground, including the stems, leaves, petioles, flowers, fruits and seeds.

Aerial Part of Plants Beginnings

When a plant seed germinates, it simultaneously sends a taproot into the ground and a shoot above the ground. The shoot is the first aerial part and consists of a tiny stem from which a pair of false leaves called cotyledons emerge. These leaves soon give way to the subsequent development of real leaves, which can be few or many depending on the type of plant. The tiny shoot grows and becomes the plant’s main stem.

Side stems, or petioles, emerge from the main stem and support the leaves. Vining plants also may develop tendrils, or small curly fibers designed to anchor the plants to some type of support such as a trellis or arbor. Most plants develop some type of flower whose task it is to produce seeds that ensure their propagation. Some plants, such as apple trees, produce fruit that contain the seeds.

Aerial Part of Plants Functionality

Each aerial plant part has a distinct purpose and each contributes to the plant’s health and survival. The main stem transports water and nutrients up from the roots and distributes them via the side stems and branches to the leaves. The leaves act as solar collectors, trapping and storing the sun’s energy for use during photosynthesis, the process by which plants manufacture their own food.

The leaves also store water, which is necessary for photosynthesis, and release unused water through a process known as transpiration. The flowers act as bait to lure insects and birds to the plant for pollination, and once fertilized, they produce the seeds that make it possible to grow other plants of that species.

Aerial Part of Plants Synergy

All plants are truly the sum of their individual parts, and they could not exist if any of those parts failed to function. The aerial parts work in conjunction with the subterranean parts toward the common goal of sustaining the plant, keeping it alive and allowing it to function according to its species. The roots supply the plant with water and nutrients from the soil, and the aerial parts access nutrients and water from the air. If disease, insect infestation or drought affects any above-ground part, it affects the whole plant and the plant may die if conditions continue.

Plants can reproduce through sexual or asexual reproduction processes.

The diversity apparent within the plant kingdom is brought about by sexual reproduction among the species, much like in the human population. Combined gene traits from two parents produce a modified version of their combined gene pool. These reproductive abilities produce genetic variations through recombined genetic materials, making plants adaptable and able to evolve into stronger, more viable organisms.

Sexual Reproduction

Just as with humans, the plant world requires both male and female parts in order for sexual reproduction to take place. The plants that don’t have these parts must reproduce through an asexual process. Flowering plants–also known as angiosperms–carry male and female parts inside their flowers, according to the Oracle ThinkQuest Education Foundation. Colorful flowers are designed to attract insects that assist in the reproduction process. Flowers that lack color rely on wind currents to assist instead. Female structures include the ovary, style and stigma, while the filament and anther make up the male structures.

Alternation of Generations

The alternation of generations is a reproductive cycle that includes both sexual and asexual reproduction in plants, according to the Oracle ThinkQuest Education Foundation. This cycle occurs only in certain types of plants, such as mosses and ferns. The asexual process uses spores in one generation of plants. The next generation consists of gametes, or male and female sex cells that sexually reproduce another generation of spores. The alternation of generations cycle is a limiting factor in terms of diversity potential when compared with the sexual reproductive process found in flowers.


The sexual reproduction process produces seeds, or zygotes, when male and female cells combine, according to the Encyclopedia Britannica. The resulting seed has half of the chromosomes from each parent cell. The creation of a new cell from a male and female cell is called meiosis. The new seed then undergoes multiple cell divisions that eventually develop into a new plant body. This cell division process is called mitosis. The resulting plant body houses a new variation of gene traits that will combine with the gene traits of another plant. These processes account for the multiple varieties of flowering plant species in existence.


Pollination is the process through which the female parts of a plant are fertilized by the male parts of another plant. The filament and anther structures that make up the male parts of a plant produce the pollen that acts as a fertilizer material, according to the Oracle ThinkQuest Education Foundation. The female parts–stigma, style and ovary–house the eggs that will be pollinated once pollen comes into contact with them. Both insects and wind currents take part in this pollination process, according to the Encyclopedia Britannica. Insects are attracted to colorful flowers and their nectars, and carry around pollen particles as they move from plant to plant. Wind currents work to blow pollen particles from plant to plant.


Conifers are plants that carry their reproductive parts on the scales of their cones, according to the Encyclopedia Britannica. Shrubs and trees make up most of this species. The male sex cells reside in pollen particles that form inside small male cones. The female sex cells are contained inside eggs that sit on female cones. Wind currents work to blow pollen particles into the air, many of which fall to the ground. The ones that don’t fall to the ground find their way to the female cones of other plants and begin the reproductive process from there.

Loss of water from aerial parts of the plant is known as
(a) Photosynthesis
(b) Transpiration
(c) Reproduction
(d) Respiration

 For plants, water is essential, but for growth and metabolism, only a small amount of water taken up by the roots is used. The process of water movement through the plant and its evaporation from aerial parts, such as leaves, stems, and flowers, takes place through the stomatal openings and can be seen as a necessary “cost” associated with the opening of the stomata to enable photosynthesis to disperse carbon dioxide gas from the air.

Complete answer:

The process of fluxing water from aerial elements such as leaves, twigs, and flowers through the plant is transpiration. By transpiration and guttation, the remaining 97–99.5 percent is lost. Leaf surfaces are dotted with pores called stomata, and on the undersides of the leaves, they are more abundant in most plants. Guard cells and their stomatal accessory cells (together known as stomatal complex) that open and close the pore are bordered by the stomata. The stomatal apertures contain transpiration.

Additional Information:


The transpiration also cools the plants, changes the osmotic pressure of the cells, and shifts the mass from the roots to the mineral nutrients and the water. The rate of bulk flow of water moving from the roots to the stomatal pores in the leaves through the xylem affects each of these factors. By regulating the size of the stomatal apertures, plants regulate the rate of transpiration. The amount of transpiration also affects the ambient evaporative demand of the leaf, such as boundary layer conductivity, humidity, temperature, wind and incident sunlight, soil temperature, and humidity may affect the opening of the stomatal.
So, the answer is, “Transpiration.


 – Photosynthesis is the mechanism of food synthesis from inorganic compounds such as carbon dioxide, sunlight, and water.
– The method of producing offspring for the continuation of the species is reproduction.
– By breaking down organic compounds like sugars, respiration is the process of releasing energy.

Name the Three Parts of the Vascular System of Plants

The vascular system of a plant refers to the tissues that are responsible for the transport of vital materials and components throughout the stems, leaves and flowers. This system transfers minerals, hormones, water and food from part to part of the plant. The three primary parts of the plant’s vascular system are the xylem, phloem and cambium.


The xylem part of the vascular system refers to specific cells that form vessels within the plant. Xylem vessels can be found in the plant’s stem. Different cell types that make up xylem include vessel elements and tracheids. These vessels are used to move, or transport, water and minerals from one part of the plant to another. Xylem tissues lives for about one year, die and are replaced by new tissue. This action creates the rings of a tree trunk. Each ring is is one layer of xylem.


While the xylem vessels are the primary transport for minerals and water, the phloem vessels move food throughout the plant. The phloem part of a plant’s vascular system is primarily made up of companion and sieve cells. Unlike xylem, which lives for approximately one year, phloem vessels live for the entire life of the plant.

 The cambium is the place where xylem and phloem cells divide and grow. This vital layer lies in between the xylem and phloem. Without the cells that the cambium produces, plants would have no vascular system.
