Exocrine Glands Definition Exocrine glands are the glands with ducts that allow the cells to secrete their products into those ducts so that they can be released onto the surface of the target cells or organs. The cells of the … Read more
Asexual Reproduction Definition Asexual reproduction is a mode of reproduction that occurs without the fusion of gametes and doesn’t involve the exchange of genetic information, resulting in offsprings identical to their parents. Asexual reproduction in living beings is characterized by … Read more
Independent Variables The Independent variable is a type of variable used in experimental sciences, statistical modeling, and mathematical modeling which doesn’t depend on any other variables in the scope of the experiment. An independent variable can be manipulated in an … Read more
Figure: Differences Between Xylem and Phloem (Xylem vs Phloem). Image Source 1: Bioninja, Image Source 2: Bioninja. Xylem Definition Xylem is a vascular tissue that transports water and dissolved minerals absorbed from the roots to the rest of the plant. … Read more
Voluntary muscles definition Voluntary muscles are the muscles that can be moved by the free will of the person and are almost always associated with the skeleton system. These muscles are attached to the bones by means of tendons, and … Read more
Vascular Plants Definition Vascular plants, also known as tracheophytes, are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant. These lignified tissues are also called vascular tissue and consist of … Read more
Transcription Definition Transcription is the process where the genetic information on a DNA strand is transferred into an RNA strand by a series of polymerization reactions catalyzed by enzymes called DNA-dependent RNA polymerases. This is the first step of gene … Read more
Taproot Definition Taproot is one of the two essential root systems where the primary root gives out branches of secondary and tertiary roots growing downwards as the primary root tapers towards the end. The Taproot system is the root system … Read more
Spermatogenesis Definition Spermatogenesis is the process of formation of mature sperm cells through a series of mitotic and meiotic divisions along with metamorphic changes in the immature sperm cell. It is the male version of gametogenesis which results in the … Read more
Figure: Differences Between Saturated and Unsaturated fatty acids. Image Source: BioNinja. Saturated fatty acids definition Saturated fatty acids are the simplest form of fats that are unbranched linear chains of CH2 groups linked together by carbon-carbon single bonds with a … Read more
Rough Endoplasmic Reticulum (RER) The rough endoplasmic reticulum is a type of endoplasmic reticulum consisting of flattened sacs, studded with protein-synthesizing particles termed ribosomes on the outer surface. The rough endoplasmic reticulum is a part of the endomembrane system that … Read more
Primary Succession Definition Primary succession is a type of ecological succession that takes place in an environment that is recently formed and lacks habitable soil but then is colonized for the first time by living organisms. Primary succession is a … Read more
Phytoplankton Definition Phytoplankton is a group of free-floating microalgae that drifts with the water current and forms an important part of the ocean, sea, and freshwater ecosystems. The term phytoplankton comes from two Greek words, ‘Phyto’ meaning plants, and ‘plankton’ … Read more
Pollination Definition Pollination is the process of transfer of male gametes (pollen grains) in plants from the male reproductive part (anther) to the female reproductive part (stigma). Pollination is the prerequisite of fertilization in plants as it ensures the movement … Read more
Oviparous definition An oviparous animal is an animal that produces eggs that later hatch to produce the young ones after being propelled out of the body of the female. Oviparity is the property of these animals where the fertilization may … Read more
Natural selection definition Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition. Natural selection is one of the four primary mechanisms of evolution, along with … Read more
Inhalation Definition Inhalation or Inspiration is a part of breathing where the air is taken into the lungs by creating negative pressure by the contraction of respiratory muscles and diaphragm. Inhalation is a vital physical process and is autonomous that … Read more
Introns Definition Introns are non-coding DNA sequences within a gene that are removed by RNA splicing during maturation of the RNA product. The term ‘intron’ represents the intragenic region which is present within a gene. The term ‘introns’ indicates both … Read more
Primary Metabolites Definition Primary metabolites are the compounds that are directly involved in the metabolic pathways of an organism necessary for its growth, development, and reproduction. These metabolites are associated with the physiological processes occurring in the organism. Primary metabolites … Read more
Monocots Definition Monocotyledons, also referred to as monocots, are flowering plants bearing seeds with a single cotyledon or embryonic leaf. There are about 60,000 species of monocotyledonous plants found worldwide where the family Orchidaceae consisting of orchids forms the largest … Read more
