Cell organelles: Structure and functions

Every organism’s basic structural and functional units are cells. They are divided into two categories: prokaryotic and eukaryotic. Prokaryotic cells can be found in species belonging to the bacteria and archaea domains. Eukaryotic cells, on the other hand, are found in fungi, animals and plants. There are some structural and functional distinctions between these two […]

In a cell, we have many membranes like plasma membrane and nuclear membrane. These membranes allow many substances to pass through them. This passage of materials will be specific and selective. Selectivity is an important concept in the conduction of ions. The ions are conducted through the membrane proteins. The selectivity filters help the selectivity

The commonly-used label, life’s building block, can be the best definition of a cell. The cells are the primary units of a living being. A cell’s structure must be complete for it to live independently. Unicellular organisms can have independent existence and carry out life’s essential duties. A cell has the capability of self-replication. The

Central Nervous System is the most crucial unit in an organism since it is the hub or the centre that commands, instigates and coordinates information. Moreover, it directly or indirectly influences all the activities within the body. The Central Nervous System in the human body is a part of the entire nervous system responsible for

Flagellum, Plural flagella,  ciliated  structure  that  serves  as  a  motility  organelle  in  many  living  species cells. Flagella, a protozoan group that includes algae, fungi, mosses, multicellular, and animal, can be found on the gametes of algae, fungi, mosses, multicellular, and animals. In sponges and coelenterates, flagellar action creates water currents that are important for respiration

Introduction to Vesicles  Vesicles can be described as tiny little sacs or blisters which help in the transportation of material outside or within the cell. Further, the Vesicles are classified into several types, including transport vesicles, secretory vesicles, and lysosomes which we will discuss today. These sacs are filled with liquid and have less than

A cell is a unit of protoplasm that is connected by plasma or cell membrane and has a nucleus. The cytoplasm and nucleus are both made up of protoplasm, which is a soul component. Mitochondria, Golgi bodies, ribosomes, endoplasmic reticulum, plastids, and lysosomes are all organelles found in the cytoplasm. Plant cells feature enormous vacuoles

The tumour is a chunk of tissue that results in a bump. All tumours are not necessarily cancerous. It is an abnormal condition where cells cut beyond the normal rate or do not depart when they should be extra. Cells in an energetic body grow, divide, displace one another. As a new cell generates, the

Tissues can be defined simply as a group of cells with similar shapes and functions. They form a cellular organisational level that serves as a bridge between cells and organ systems. The functional groups of tissues are then combined to form organs. Let’s go over the different types of tissues in each organ in detail. 

While looking through a microscope at an animal or plant cell, you may have noticed a number of organelles that collaborate to perform the cell’s tasks. Ribosomes, which are in charge of protein synthesis, are one of the fundamental cell organelles. The ribosome is a large protein-RNA complex that plays a vital role in interpreting
