These cells are also known as melanocytosis or microcythemia, this condition typically causes no signs or symptoms and is usually detected incidentally on routine blood tests complications. In this type of RBC amount of haemoglobin is normal. These are immature RBC that are destroyed in the spleen. Due to vitamin B12 deficiency, RBC becomes larger in size called macrocytes. Macrocytic Cells- Macrocytosis is a process that is used to define the red blood cells that are larger than normal. A macronucleus is the larger type of nucleus in ciliates. It is found in suctorian types of protozoans and ciliate types of protozoans. Macronucleus affects the activity of many cells. It performs a major role in controlling the non-reproductive cell functions, like metabolism. Macronuclei can undergo direct division without mitosis. The ploidy of the macronuclei is polyploid. The size of the macronucleus is larger than the normal nucleus size. Macronucleus- A macronucleus is also known as meganucleus. Or the head of the macrocephalic person is larger than the 98th percentile. when the circumference of a person’s head is more than two standard deviations above average for their age. There is a standard criterion that is used to define macrocephaly. This situation generally occurs as a symptom of complications or conditions in the brain. Macrocephaly- Macrocephaly is the condition in which an overly large head is present than the normal size. Sulphur generally helps in amino acid formation. Secondary Nutrients- calcium, magnesium, and sulphur are the main secondary nutrients. Potassium helps in regulating the function of the enzyme. These nutrients help in performing the major function of the plants. Primary Nutrients- nitrogen, phosphorus, and potassium are the main primary macronutrients. Carbon, hydrogen, and oxygen are the main structural macronutrients. Structural Nutrients- structural nutrients help in the formation of plant structures.

Macronutrients can be divided into three types: The requirements for the micronutrients are around 0.1 to 1 mg/g. Its requirement is about one to ten mg/g. The macronutrients are required by the plants in more amounts. Macronutrients- Macronutrient is an example of Biology Root Words for Macro. Intracellular killing- Most bacteria are slaughtered in the phagolysosomes by the hydrolytic enzymes within a few minutes of phagocytosis. The lysosome contains hydrolytic enzymes and other bacterial substances. The membrane of which fuses with the lysosomes forming a phagolysosome. Ingestion- Phagocyte engulfs the particular material into a vacuole. This movement is active in nature.Īttachment- the infective agent gets attracted to the membrane of the phagocytes. This kind of active movement of the cell is called diapedesis.Ĭhemotaxis- now these leukocyte cells move towards the pathogen by chemotactic movement. Vasodilation- at the site of entry, increased diameter of blood vessels.Īdhesion- accumulation of leukocytes at the periphery of blood vessels due to decreased blood flow.ĭiapedesis- now the leukocytes migrate from the blood vessel by active movements into the extracellular fluid. Monocytes are liberated at the site of infection these later convert into macrophages. The most important phagocytes are macrophages and neutrophils. Phagocytosis is exhibited by some types of WBC’s such as WBC's are called phagocytes. In response to pathogenic infection, the total count of WBC in the body increases. Macrophages of the spleen are known as reticular cells. Macrophages of the thymus gland are known as hessel’s granules. Macrophages of the brain are known as microglial cells. Macrophages of blood cells are known as monocytes. Macrophages of the liver are called kupffer cells. Macrophages of the lungs are called dust cells. These cells are also called scavenger cells of connective tissue because they destroy dead or damaged cells to clean connective tissue.

They destroy bacteria and viruses by phagocytosis. In this cell cytoplasm is agranular but due to the presence of more lysosomes, it appears granular. The quantity of the cytoplasm is more in this type of white blood cells. It is amoeboid in shape with a bean or kidney-shaped nucleus. It is the second-largest in size and second maximum in number.

Macrophage- macrophage is a good example of Biology Root Words for Macro. Let us discuss examples of root words starting with macro terms one by one. Macro is a word that originated from the Greek word makros which means large.Įxamples of Root Words Starting with Macro
