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

Taxonomy and Systematics: Objectives and list of Taxonomy Systematics

Systematics Systematics is the study of biological diversity and the organisation of the data into a classification. The word systematics is derived from the Latin word ‘systema,’ which refers to the orderly organisation of organisms. It encompasses the species’ evolutionary relationships. Plant systematics is the study of how plants and their evolutionary descent interact.  Similarities,

Tapetum Types and Functions

Introduction The tapetum is a specialised layer of nutritive cells found between the sporogenous tissue and the anther wall within the anther of flowering plants. Tapetum is necessary for pollen grain nutrition and development, as well as a source of pollen coat precursors. The cells are often larger and feature more than one nucleus per

Tapetum

The tapetum is a specialised layer of nutritive cells placed between the sporogenous tissue and the anther wall of flowering plants. Tapetum is critical for pollen grain nutrition and development, as well as a source of precursors for the pollen coat. Cells are often larger and contain several nuclei. As sporogenous cells divide, the nuclei

Tallest Gymnosperm

Gymnosperms, also known as Acro Gymnospermae, are a flowerless plant family that produces seeds and cones. Gymnosperm is a flowerless plant whose name literally means “naked seed.”  Gymnosperm seeds are not enclosed within the ovaries, therefore this is the case. Instead, they’re exposed on the surface of leaf-like structures called bracts, where they sit. Gymnosperms

Syconus

Syconus is a composite fruit formed from a hollow fleshy inflorescence stalk inside which tiny flowers develop. The female flowers produce small drupes, the `pips. Example: Fig (Ficus carica). Syconus fruits are the type of multiple fruits developed from the hypanthium, a type of inflorescence. The Dorstenia and Ficus are the main examples of Syconus fruit.  They are usually enlarged
