Introduction Tissues are the supporting units found in living organisms throughout their bodies. These tissues are found in the bodies of plants and animals however they are different in structure and function entirely. These units have their own set of functionalities that supports different organs of the body. The tissues are made of cells and […]
Introduction Monocotyledonous plants have large chromosomes, which are nicely visible in the experiments. The meristematic tissues that are enabled at the tip of the roots provide a good source for the study of the process of mitosis. Onions are monocotyledonous plants possessing large chromosomes, hence their root tip is used for studying. Aim Cell division […]
Introduction The cell cycle in eukaryotes usually comprises two distinct processes, namely, mitosis and meiosis. Mitosis occurs in somatic cells and ensures the division of a parent cell into two daughter cells that carry the same number of chromosomes as were present originally in the parent cell. Hence, the level of ploidy is maintained, or the division […]
Introduction Respiration is one of the vital processes in our body that supports life. It is a process through which energy stored in the food is converted into chemical energy which is a source of fuel for the body and provides energy to the body. Respiration at the cellular level is called cellular respiration. Cellular […]
Introduction Imagine a deer fleeing for its life as it is being chased to death by a predatory cheetah. The deer runs fast and during this its breathing rate increases, and heart pounds furiously in anxiousness. Its legs move the fastest they possibly can. Such intense physiological responses to an external threat (stimulus) are a part of […]
Introduction Every organism whether single-celled or multicellular is made up of cells. They provide body shape and structure and perform a variety of tasks to keep it running. A cell is the fundamental unit of life. According to Cell Theory Hypotheses, “Cell is the fundamental unit of life that gives everything and is self-sufficient in […]
Introduction All living organisms possess cells. It is most important structurally, biologically, and functionally. By division of cells, they increase the numbers and form all the structures in the body. There are three essential parts that are present in a cell, namely plasma membrane, cytoplasm, and nucleus. The nucleus is a spherical organelle that is […]
