Muscle tissue is made up of cells that can contract together and allow animals to move. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.Stem cells are divided into several categories according to their potential to differentiate. Nervous tissue is made of specialized cells that transmit information through electrochemical impulses, such as the tissue of nerves, the spinal cord, and the brain.An organ is a structure made up of different tissues that perform specific bodily functions.
For example, blood pressure is controlled by a combination of the renal system (kidneys), the circulatory system, and the nervous system. The diagram shows five levels of organization in a multicellular organism. There are eleven different organ systems in the human body, each with its own specific functions. Key Points. Cells are the most basic unit of life at the smallest level of organization. Organs may be solid or hollow, and vary considerably in size and complexity. A cell is the basic unit of life. The most basic unit is the cell; groups of similar cells form tissues; groups of different tissues make up organs; groups of organs form organ systems; cells, tissues, organs, and organ systems combine to form a multicellular organism.

Level 1: Cells. Quick Witted Owl Lesson Plans Made Easy. Cell. Muscle tissue, connective tissue, and neural tissue are An organ is a system of tissues that work together on a larger scale to An organ system is a group of organs that work together to perform An organism is a recognizable, self-contained individual. Levels of Organization, Cell Theory, Cell Theory. The first and most basic level of organization is the cellular level. The heart, lungs, and brain are all examples of organs.An organ system is a collection of organs that that work together to perform a similar function. Cell: Basic structural and functional unit of a living organism: Tissue: Group of cells with similar structures, working together to perform a shared function: Organ by. At cellular level, organisms can be classified into two: single-celled organisms (unicellular) and multiple-celled organisms (multi-cellular). There are two kinds of cells: plant cells, which have a rigid cell … Cells also contain many structures within the cytoplasm called organelles, which perform various cellular functions.Cells may be prokaryotic (without a nucleus) in bacteria and archaea (single-celled organisms), or eukaryotic (with nucleus-enclosing DNA) in plants, animals, protists, and fungi. These levels start from the smallest unit of life and work up to the largest and most broad category.The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.Tissue is made of cells that work together to perform a certain task. While it is apparently not the smallest particle (organelles, molecules, and atoms are even smaller in size), the cell is called as such because it is the smallest living entity that can function on its own. While cells vary greatly in their structure and function based on the type of organism, all cells have a few things in common. Cells can be prokaryotic (without nucleus) or eukaroyotic (with nucleus). She writes for various websites, covering everything from marine biology to online programming and book publishing. cell, tissue, organ, organ system, organism.
