Microscopic Characters of Coriander- Coriander (Coriandrum sativum) has medicinal properties and has been used in traditional medicine to treat various illnesses. Through study of Coriander’s microscopic characteristics, scientists hope to gain more insight into its composition and potential therapeutic uses.
Microscopic Characters of Coriander, Coriander leaves are compound, with ovate and deeply lobed leaflets. Stomata are located on the lower surface of these leaflets and enclosed by two guard cells of rectangular shape arranged in an even pattern. Furthermore, chloroplasts give off their characteristic green hue.
Coriander stems are cylindrical in shape and measure between 2-3 mm across. They are covered with a smooth, greenish-brown epidermis that is sparsely hairy. The stem consists of multiple layers: epidermis, cortex and pith – with cells in the cortex arranged circularly while those of the pith being large and rectangular.
Coriander flowers are small and white, arranged in umbels. The corolla consists of five petals with a tubular calyx. The ovary is inferior and contains two carpels while the five stamens at its base form an umbel.
Coriander seeds are ovoid in shape and measure about 3-5mm across. They’re yellowish-brown in color with several longitudinal ridges on their surface. The endosperm, which contains oil and protein, is rich while the embryo remains small.
Microscopic Characters of Coriander
Coriander leaves, commonly referred to as cilantro, are one of the most distinctive and easily recognizable features of this plant. They consist of multiple leaflets that form an alternate pattern on the stem and can grow up to 50 cm long overall.
The upper surface of the leaflets is smooth and glossy, while their lower surfaces feel slightly rough to touch. They’re bright green in color with a distinctive citrusy aroma that defines this herb.
Chloroplasts, the organelles responsible for green hues in plant cells, are abundant. Chloroplasts are essential in photosynthesis – the process by which plants convert sunlight into energy.
Stomata, or tiny holes that allow gas exchange, are located on the lower surface of leaflets and protected by two guard cells. These rectangular-shaped cells are arranged in an even pattern across the leaflets.
Coriander leaves are an iconic feature of the plant, their distinctive shape and composition having led to their widespread use in cooking and traditional medicine.
The stem of coriander plants is slender, cylindrical and can grow up to 50 cm tall. It usually has a green hue with slight ridges along its perimeter, with alternate leaves and branches sprouting from nodes.
The stem is composed of multiple layers, such as the epidermis, cortex and vascular tissue. The outermost layer, known as the epidermis, consists of just one cell layer and serves to protect inner stem tissue.
The cortex is the middle layer of a stem and composed of multiple cell layers. This layer plays an essential role in storing and transporting nutrients and water throughout plants.
The vascular tissue, located at the center of a stem, consists of two types of tissues: xylem and phloem. Xylem transports water and minerals from roots to leaves while phloem moves sugars and other organic compounds throughout the plant.
The stem of coriander contains small, hair-like structures known as trichomes that can be observed under a microscope. These cells produce and secrete essential oils that give the plant its distinct flavor and aroma.
Overall, the stem of a coriander plant is an integral element of its structure and function, supporting, transporting nutrients and water, as well as housing essential structures for producing essential oils.
Coriander flowers are small and white, clustered into umbels. Each umbel can contain up to 20 blooms, with multiple umbels appearing on each stem.
Flowers are composed of several layers. The outermost calyx, known as the calyx, consists of five sepals that shield the developing flower while inside lies five petals that make up the corolla, visible part of the bloom. Usually white or pale pink in hue, this part has a distinctive shape with five pointed lobes.
Within the corolla are the reproductive structures of a flower. Stamens, also known as male and female stamens, consist of filament and an anther. The latter houses pollen–the male gamete that fertilizes the female gamete or ovule.
The female reproductive organ, commonly referred to as the pistil, is located at the center of a flower. This organ consists of three components: stigma, style and ovary. Stigma is the sticky surface at the top which attracts pollen while style acts like a tube connecting stigma to ovary. Ovules – fertilized female gametes that develop into seeds when fertilized by pollen – reside inside each pistil.
Overall, the flowers of a coriander plant are essential in its reproductive process, producing pollen and ovules necessary for seed production. Furthermore, their aesthetic appeal draws in pollinators such as bees and butterflies to pollinate it.
Coriander seeds are the part of the plant most often used as a spice. These small, round seeds are light brown in color with a hollow cavity in their center.
Each seed consists of two halves that are separated by a thin membrane. The outer surface is covered in small ridges and furrows, giving it an uneven texture.
Crushed or ground coriander seeds release a warm, citrusy aroma with subtle hints of sweetness and spice. They’re widely used in cooking and baking as well as the production of various foods, beverages, and personal care items.
Coriander seeds are not only popular for their culinary uses, but they may also possess health benefits. They contain various beneficial compounds like antioxidants, anti-inflammatory agents and digestive enzymes; some studies even suggest that coriander seeds may have antimicrobial properties as well – making them useful in the treatment and prevention of certain infections.
Coriander seeds are an invaluable asset to human life, from cooking and flavoring to health and wellness.
Coriander is an incredibly versatile plant, valued for its leaves, stems, flowers and seeds. Each part has its own distinctive qualities and uses; from the fresh citrusy taste of the leaves to the warm aroma of the seeds. It finds widespread applications in cooking and baking as well as personal care products and medicine.
Coriander seeds contain beneficial compounds like antioxidants and anti-inflammatory agents that may have health benefits. Furthermore, studies suggest coriander seeds may possess antimicrobial properties which could make them effective in the prevention and treatment of certain infections.
Overall, coriander is an invaluable plant with numerous uses and advantages. Its distinctive flavor profile and potential health advantages have made it a go-to choice in numerous industries and cultures around the world.
