Rough vs Smooth Endoplasmic Reticulum- Definition, 13 Differences, Examples

Differences Between Rough and Smooth Endoplasmic Reticulum

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 is present in the cytoplasm of the cell. The organelle is involved in the synthesis, folding, modification, and transport of …

Primary vs Secondary Succession- Definition, 12 Differences, Examples

Differences Between Primary and Secondary Succession

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 series of events occurring in an order to develop a stable ecosystem. The new environments are usually formed due to …

Phytoplankton vs Zooplankton- Definition, 16 Differences, Examples

Differences Between Phytoplankton and Zooplankton

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’ meaning drifter. Phytoplanktons are autotrophic as, like land vegetation, they are also provided with chlorophyll to make their own food. …

Pollination vs Fertilization- Definition, 12 Major Differences, Examples

Differences Between Pollination and Fertilization

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 of gametes in otherwise immobile plants. The act of pollination is brought about by various pollinating agents like wind, water, …

Oviparous vs Viviparous- Definition, 11 Major Differences, Examples

Differences Between Oviparous and Viviparous

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 be external or internal, but the young ones are always hatched out of the body. Oviparous animals include most fishes, …

Natural vs Artificial Selection- Definition, 17 Major Differences, Examples

Differences Between Natural and Artificial Selection

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 mutation, genetic drift, and migration. Charles Darwin popularized the concept of natural selection during his studies on evolution. According to …

Inhalation vs Exhalation- Definition, 15 Major Differences, Examples

Differences between Inhalation and Exhalation (Inhalation vs Exhalation)

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 occurs without concise or control. However, breathing as a process can be controlled or interrupted to certain limits. Inhalation is …

Introns vs Exons- Definition, 12 Major Differences, Examples

Differences between Introns and Exons (Introns vs Exons)

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 the DNA sequences within the gene and the corresponding sequence in RNA transcripts. Introns are found in the genes of …

Differences between Primary Metabolites & Secondary Metabolites

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 are produced in the organism during the growth phase, as a result of the growth mechanism. The growth phase associated …

Differences between Monocotyledons and Dicotyledons

Monocotyledons 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 group in both monocots and in angiosperms with about 20,000 species. The second most abundant monocotyledons include grasses in the …
