The Shoot System

Living organisms are generally classified as plants and animals. However, there are various other life forms such as bacteria, unicellular organisms, fungi, viruses, etc. too. These life forms are classified based on the structure of their various systems and what functions they perform.  Plants are one such lifeform. The plant structure consists of many complex […]

The Medulla, or Pith

In Biology, the pith refers to spongy, typically mushy material that is present in the centre of the stems and roots of many plants. This tissue is also known as the Medulla. There are many parenchyma cells in the medulla tissue, a type of plant cell characterised by its large size and thin cell wall.

The Internal Structure of the Monocot Stem

Monocots or monocotyledons are found in grass or grass-like flowering plants, also known as angiosperms. Generally, a flowering plant is categorised based on the number of cotyledons. What fascinates us the most is the internal structure of the monocot stem. A monocot plant is defined based on the presence of a single embryonic leaf, hence

The Fruit

Introduction Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. If the fruit is formed

The following are the objectives of plant taxonomy

Classification is the practice of grouping things into useful categories based on plainly observable characteristics. As a result, all living species can be divided into different taxa based on their properties. Taxonomy is the term for this classifying procedure. The external and internal structure of organisms, as well as cell structure, development process, and ecological

The Flower

A flower, very often referred to as a blossom, it is the reproductive structure observed in flowering plant life(plants of the division Angiospermae). The biological characteristics of a flower is to facilitate reproduction, typically via means of providing a mechanism for the union of sperm with eggs. Flowers might also additionally facilitate outcrossing (fusion of sperm and eggs from distinct individuals in a

The Basic Plant Organs

Plant organs come in a variety of shapes and sizes. The plant’s body is anchored to the earth by the root, which absorbs water and mineral salts. Aerial organs such as leaves, flowers, seeds, and fruits are supported by the stem, which also conveys water and mineral salts from the ground to the aerial organs,

Tetralocular

In Brassica rapa, a genetic locus for tetralocular ovary (teto) was discovered, and it was discovered as the number of locules and the breadth of the silique are linked. Abstract Brassica rapa is a polymorphic species with a wide range of vegetables and oleiferous varieties. The yellow sarson group (subspecies trilocularis), that is predominantly grown

Tetracarpellary

An angiosperm plant’s flower is its reproductive organ. Some flowers are males, while others are females or bisexuals (having both and female reproductive organs). The gynoecium is the innermost whorl of female and bisexual flowers. The gynoecium is made up of one or more pistils, each of which is made up of one or more

Tendril stems

It’s a type of plant organ that helps support and anchor the vining system. It might be a modified leaf, leaflet, leaf tip, or leaf stipule structure. They can also come from modified stem branches, such as those found in grapes. Climbing plants have thin, thread-like growths on their stems and leaves. There are two
