Introduction A group of traits or abnormalities that are intended to occur together to result in specific diseases is known as a syndrome. In simple words, the syndrome is a collection of traits that have distinctive features and that have run together. The syndrome is derived from the Greek word syn means together and drome stands for a run. Most of the syndromes were named after the scientist who first discovered them. For example, Down syndrome and Marfan syndromes are two syndromes that are discovered by the respective scientists Dr Down and Dr Marfan. Both turner syndrome and Klinefelter syndrome ... Read More

Introduction Plants suck water from soil with the help of roots for metabolic reactions and it's a continuous process. Only a small amount of water is used by plants and the remaining water is lost by transpiration. The water is lost in the form of water vapour. Transpiration is the process of loss of water in the form of water vapour. Transpiration occurs mainly through stomata. Apart from these, it can happen through surfaces of leaves, aerial parts, flowers, and stems. Vascular plants like grass lose water in the form of water droplets from the tips or margin of the ...

Introduction Transpiration and evaporation are the processes that naturally occur in the atmosphere and they both differ from each other. Transpiration involves the loss of water in the form of vapour from the aerial parts of plants like leaves, etc. Evaporation involves the transformation of water from its liquid state to its gaseous state. It differs from transpiration as it is a physical process that not only occurs in living organisms but also occurs in non-living entities. Transpiration It is a slow biological process that results in the loss of water from the aerial parts of the plants like ... Read More

Introduction Plants are multicellular eukaryotes that consist of several tissues to perform specialised functions. Vascular tissues are significant for carrying water, minerals, and food to varying parts of the plant. It is made up of two appropriate tissues such as xylem and phloem. Vascular plants can grow higher than other plants because of their rigidity. Water is the main solvent for plant nutrition, important for photosynthesis and transport of minerals, hormones, and other molecules. Higher plants have developed transportation systems for the conduction of water known as xylem. Xylem is wood in many plants that is an essential raw material ... Read More

Difference Between Thorns and Spines

Introduction Thorns and spines are modified organs of plants. They evolved from a simple leaf or shoot to function as a defensive organ to protect themselves from the predators, sometimes they used it as a climbing tool. In xerophytes, the stems are modified to phylloclades that store water for future use and change the leaf conformation into the spines. The spines are adapted because the leaves decrease the surface volume of the leaf lamina to control the evaporation and reduce transpiration rates as well. Whereas the thorns mainly control the defense. Now let’s start the further discussion.. Thorns Thorns ... Read More

Introduction The immune system protects the body from foreign substances which are harmful to the body. Bacteria, viruses, fungi, and toxins are included in the foreign substances. The immune system comprises an extensive network of cells, organs, proteins, and tissue present in the body. The immune system can be recognized and eliminated faulty cells. Sometimes immune system fails to fight against diseases. The immune system mainly consists of a range of components WBC, spleen, bone marrow, lymphatic system, thymus, tonsils, adrenals, and appendix. T cells and B cells are two lymphocytes produced in lymphoid organs. The thymus gland and ... Read More

Introduction to the autonomic nervous system The nervous system is an important system that plays an important role in every action of life and is responsible for all involuntary and voluntary actions of our body. It constitutes the nerve network, spinal cord, and brain and is classified into three divisions. The central nervous system, autonomic nervous system, and peripheral nervous system are the three divisions of the nervous system. Autonomic nervous system control and regulates the involuntary function of the internal organs. This function is done without a person's conscious effort. The autonomic nervous system is segregated into sympathetic and ... Read More

Difference Between Sporophyte and Gametophyte

Introduction Angiosperms are the most progressive plant species inhabiting the land. Reproduction in flowering plants starts with the division of fertilized egg to form an embryo. The plants follow a haplodiplontic pattern that alternates between gametophytic and sporophytic phases. Thus it is important to have clear knowledge between the two generations. Gametogenesis occurs in gametophytes followed by a union of gametes to form a diploid zygote. The fertilization results in the formation of diploid sporophytes, producing haploid spores through meiosis. The spores so formed undergo mitotic division to yield multicellular haploid gametophyte. So in Plantae, a single genome creates two ... Read More

Difference Between Spermatogenesis and Oogenesis

Introduction In all living things reproduction is the criterion that makes life move from one generation to the other. Gametogenesis is that process which takes place both in the male and female sex. In gametogenesis, the formation of the male gametes (sex cells) and female gametes takes place separately. In biological terms, gametogenesis can be termed as the process in which a diploid cell divides and transforms into mature haploid gametes. Gametogenesis is of two types: Spermatogenesis and oogenesis. The major steps in gametogenesis are − Mitotic division and cell growth of germ cells Meiosis I and II occur ... Read More

Difference Between Sperm and Ovum

Introduction The sperm is a male gamete, produced in the testes. It remains inactivated before ejaculation in the female tract that has a specific pH range helps in the capacitation of the sperm and controls its motility towards the ovum. The mitochondria supplies energy and the flagellum helps in propelling. In the ovary, the ovum is produced and matures but remains dormant. Though a million sperms are ejaculated, only the capacitated one can penetrate the outer membrane via dissolving to enter inside the ovum. Only the nucleus and the centrioles of the sperm can enter the ovum leaving the flagellum. ... Read More
