Plant Kingdom

Introduction The Plant Kingdom is one of the significant Kingdom classes of the Five Kingdoms classifications. In a nutshell, the Plant Kingdom is a class of all types of plants and their seeds. The Plant Kingdom can acquaint you with all significant concepts of plants, starting from their general characteristics, types, and importance. The Plant […]

Plant Kingdom Plantae

Plantae is the plant kingdom that encompasses all of the world’s plants. They are eukaryotes, which are multicellular organisms. They are distinguished by the presence of a stiff structure known as the cell wall that surrounds the cell membrane. Chlorophyll, a green-colored pigment found in plants, is essential for photosynthesis. As a result, they eat

Pollinating Agents

Pollen grains are transported from the pollen-producing plant parts to the ovule-bearing organs or the ovules (seed precursors) themselves. Pollination is a procedure that ensures a plant’s life cycle is successful. Plant fertilisation would be impossible without pollination, hence it is critical for the production of fruit and seed crops. Pollen is delivered to the

Sepals

The flower’s outermost component, the sepals, is a small, leaf-shaped, green-colored component. They are the vegetative part of a flower that protects the growing buds and holds the petals in place while the flower is in bloom. The sepals are the leaves that have been changed. Depending on the flower species, the sepals vary in

Wind Pollination

Introduction Many different types of flowers are pollinated without the need of animals (such as insect, bird, or mammal). Few of them are pollinated by the currents of wind or water, here wind and water acts as a vectors. These flowers do not usually attract animal pollinators. Wind Pollination Wind pollinator flowers are generally small,

Wind Dispersal

In Spermatophyte plants, seed dispersal refers to the movement, spread or transport of seeds away from the parent plant. Plants show limited mobility and are dependent upon a variety of dispersal vectors in order to transport their seeds, this involves both the abiotic vectors, like those of the wind, and biotic (living) vectors like those

What is Pleiotropy

Pleiotropy corresponds to a specific gene expressing multiple traits. These traits that have been expressed might not really be related. Pleiotropy was discovered by geneticist Gregor Mendel, who is better remembered for his pea plant research. Plant flower colour (white or purple) still was associated with the colour of the leaf axil (area on a

What is Equisetum

Equisetum, also called horsetail, snake grass, or puzzle grass, is the main living genus in Equisetaceae, a group of plants, which are created by spores as opposed to seeds. It is a “living fossil”, the main living family of the whole subclass Equisetinae, which for around 100 million years was substantially more different and overwhelmed

What is DNA Fingerprinting?

Introduction It is possible to describe tissue culture as the method of in vitro cultivation of plant or animal cells, tissues, or organs in the nutritional medium under aseptic circumstances, commonly in a glass container, under aseptic settings. A variety of terms are used to describe it, including “septic culture” and “in vitro culture.” Depending

What is Cycas?

The stem is unbranched and straight. The leaf bases are strong, woody, and long-lasting. The stem becomes rougher as a result. The apex of the stem is surrounded by a clump of brown scales. The stem’s base is covered in pinnate compound leaves. The stem develops at a glacial rate. It grows a cluster of
