The stigma, style, and ovary are the three main structures of the gynoecium, carpel, or pistil. It is the female reproductive portion of the flower that carries the female gametes or ovules within an ovary. The female reproductive component, as well as other sections, are supported by the pedicle or thalamus, which is located near […]
The goliath bumblebee, Apis dorsata fabricius or rock bee, can be found across southern Asia. The three subspecies of Apis dorsata are Apis dorsata dorsata, Apis dorsata binghami and Apis dorsata breviligulata. The nests of rock bees are different from the western bumble bees – Apis mellifera L. Rock bees usually assemble near exposed areas

Anatomy of flowering plants: Tissue systems, Biology, Class 11, NEET, Structural Organisation in Animals and PlantsThe term “protist” refers to a wide group of unicellular and multicellular creatures. Protists have membrane-bound organelles and are classified as eukaryotes, meaning they have a nucleus. Protists are polyphyletic, deriving from multiple common evolutionary ancestors. They are organisms that resemble other species such as plants, animals, or fungi but lack the qualities necessary to

Anatomy of flowering plants: Tissue systems, Biology, Class 11, NEET, Structural Organisation in Animals and PlantsAngiosperms, more than any other group of plants, dominate the Earth’s surface and vegetation in more areas, particularly terrestrial habitats. As a result, angiosperms are the most important final food source for birds, animals, and humans. Flowering plants are also the most economically important group of green plants, as they provide medications, fibre, lumber, ornamentals,

Anatomy of flowering plants: Tissue systems, Biology, Class 11, NEET, Structural Organisation in Animals and PlantsAmyloplasts are a type of plastid known for storing food materials. Plastids are a double-membraned structure found in plant cells, algae and some eukaryotes. The name was given by A.F.W. Schimper. Plastids may contain pigments to provide colour to the cells and are further divided into chromoplast, chloroplast and leucoplast. Amyloplasts fall into the category
What are Lipids? Water is a polar molecule. These organic compounds are nonpolar molecules that can only be dissolved in nonpolar solvents. These molecules are produced by the liver in the human body and can be found in some red meats, oil, fried meals, cheese, whole milk and butter. Properties of Lipids Fats and oils

Anatomy of flowering plants: Tissue systems, Biology, Class 11, NEET, Structural Organisation in Animals and PlantsA great diversity of species has developed on Earth throughout millions of years, and many previous efforts to categorize them have been undertaken. Small insects to large trees to vividly colourful flowers or birds are among the living forms surrounding us. The notion of biological categorization was proposed for ease of research and identification, but

Polysaccharides are polymers of monosaccharides and they function chiefly as food and energy storage in the form of starch and glycogen and structural materials e.g., cellulose. They are convenient
The alkali metals and alkaline earth metals, often known as groups 1 and 2, are located in the s-block of the periodic table of elements. Helium is also classified as an element of the s block. The s orbital is filled by the fundamental quantum number “n.” The s orbital can hold a maximum of

A binomial name means that it has two parts. These two parts are the generic name (genus name) and the specific name, also known as a specific epithet. These names form part of the botanical nomenclature. In short, it is a type of two-term
