In the biology dictionary, an organ is a group of tissues that collectively form a functional unit that is specialized to carry out a certain function. The Latin organum phrase means an “instrument” or “tool”. The most common examples when people think about organs are the kidneys, brain...
All cells have non-membrane-bound organelles. These organelles usually have a protein or RNA structure and do not have a plasma membrane. The plasma membrane is a double layer of phospholipids that surrounds both the cell itself and some organelles. Non-membrane-bound organelles are essential to...
Inside the cell are organelles (e.g. nucleus, mitochondrion, endoplasmic reticulum, and Golgi apparatus) and many other cytoplasmic structures. A basic biology definition would be is that it is the study of living organisms. It is concerned with all that has life and living. (Ref.1) In ...

They then became organelles and benefitted from the protection of the cell membrane while the organisms that engulfed them gained an evolutionary advantage of performing photosynthesis and cellular respiration. Predator-Prey Relationships, Population Cycles and Population Dynamics ...

Examples of specialized cells include heart muscle cells and parietal cells found in the stomach. The hierarchy that forms parts in living organisms follows this order; atoms, molecules, organelles, cells, tissues, organs, organ systems. Various organ systems form an organism. ...

After many generations of evolution, the ancestral host cells evolved into the present-day eukaryotic cells containing the organelles — mitochondria and chloroplasts— which are likely of bacterial origin, particularly from aerobic bacteria and ...
Now that we know the basic classification of cell organelles, let’s move ahead and learn about ribosomes in detail which is the main topic of this article. We will answer some common questions and doubts around the topic too, so keep reading… Ribosomes Definition Biology definition: The ri...
In biology, atissueis a group of cells and their extracellular matrix that share the same embryonic origin and perform a similar function. Multiple tissues then form organs. The study of animal tissues is calledhistology, orhistopathologywhen it is concerned with diseases. The study of plant tiss...
