“Cells are the building blocks of tissues and therefore multicellular organisms. Using specific examples‚ describe some of the mechanisms used by cells to provide organisation within tissues containing different cell types.” One cannot adequately contemplate the organisation of tissues‚ let alone organisms. Words fall short when explaining the sheer vastness of their complexity. It is incredible that such astonishingly patterned structures can be formed from so many individual cells but greater

Unicellular organism From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search "Single-celled" redirects here. For prison cell assignment‚ see Single-celling. Valonia ventricosa is among the largest unicellular species. A unicellular organism‚ also known as a single-celled organism‚ is an organism that consists of only one cell‚ unlike a multicellular organism that consists of multiple cells. Historically the simple single celled organisms have sometimes been referred to as monads

Chapter 1: Classification and Characteristics of Living Organisms Organisms - An individual living thing‚ such as an animal or a plant‚ is called an organism. There are seven characteristics of living organisms – Nutrition Nutrition is the process by which organisms obtain energy and raw materials from nutrients such as proteins‚ carbohydrates and fats for growth and repair. Photosynthesis is the process of nourishment of green plants. Digestion is the process of nourishment of green

* NCERT 1. Reproduction in Organisms INTRODUCTION Biology in essence is the story of life on earth. While individual organisms die without fail‚ species continue to live through millions of years unless threatened by natural or anthropogenic extinction. Reproduction becomes a vital process without which species cannot survive for long. Each individual leaves its progeny by asexual or sexual means. Sexual mode of reproduction enables creation of new variants‚ so that survival advantage is enhanced

Stem Cell Research Stem cells are defined as “an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type‚ and from which certain other kinds of cell arise by differentiation.” (Google) And as science has progressed in the last few decades‚ the ability to experiment and research these fascinating cells has progressed at an exponential rate. However‚ the controversy over this new scientific discovery has made it very difficult for

The creation of these minimal genomes can be helpful and harmful at the same time. There are many opinions out there about the subject‚ I will share some of those and my position on the subject. First let me just start with my personal position on minimal

Abstract Organization as a living organism. This metaphor view Organizations from a Biological point of view. Organizations as living systems environment on which they are dependent on each other to satisfy various needs. When studying and comparing organization with living organism it was determined that organizations share the same concept as of a living organism. An organization needs to have the right environment in order to survive‚ adapt‚ surpass turbulence and reproduce; the cycle of
