Cell Specialisation All cells are designed to perform a particular job within an organism‚ that is‚ to sustain life. Cells can become specialized to perform a particular function within an organism‚ usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. The cells combine together for a common purpose. All organisms will contain specialised cells. There are hundreds of types of specialised cells. Below is listed some of the major ones

Like Father‚ Like Son Man’s goal in life is not to do something incredible during his lifetime‚ but instead to leave something incredible behind for future generations to act and build on. In Cormac Mccarthy’s The Road‚ a man and his son struggle for survival in a post-apocalyptic era. The majority of this struggle revolves around the lack of food in the world and the boy’s constant fear of life itself. In order to combat these struggles‚ the man is forced to have all faith and must keep trekking

Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions

to have killed off the dinosaurs suggest it may have just been the final blow‚ and that the reptiles were already suffering from a finicky climate prompted by volcanic eruptions long before the meteorite struck. "The [asteroid] impact was the coup de grace‚" Paul Renne‚ a geologist at the University of California‚ Berkeley‚ said in a statement. The research‚ detailed in the February 8 issue of the journal Science‚ adds to the ongoing scientific debate over what exactly killed off the dinosaurs.

Prokaryotic Cell Structure Bacterial Cell Structure Mariana Ruiz Villarreal/Wikimedia Commons Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System‚ prokaryotes include bacteria and archaeans. Prokaryotes are able to live and thrive in various types of environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals.

The inside of the prison is really run down‚ defiantly a playpen for cons and does nothing more than keep them locked

Cell Theory In biology‚ cell theory is a scientific theory that describes the properties of cells‚ the basic unit of structure in every living thing. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory states that new cells are formed from pre-existing cells‚ and that the cell is a fundamental unit of structure‚ function and organization in all living organisms. It is one of the
