The five levels of organization in a multicellular organism are cells, tissues, organs, organ systems and organisms. The level of complexity and functionality increases going from cells to organisms.Know More
Cells are the basic unit of a multicellular organism. Humans have many types of cells, including blood cells, nerve cells and bone cells. Cells with similar structure and function merge to form tissues such as epithelial or connective tissue.
Organs, such as the heart or kidney, are composed of different types of tissue to perform a specific function. Organs come together to constitute organ systems such as the nervous system, digestive system and immune system. Together, these organ systems make up an organism.Learn more about Cells
Multicellular organisms are composed of many cells, which are integrated and independent to various degrees, according to Encyclopædia Britannica. A multicellular organism's development is accompanied by cellular specialization and division of labor. The cells of multicellular organisms become efficient in one process and are dependent on other cells to survive.Full Answer >
Cows, buffaloes, elephants, monkeys, dogs and cats are all examples of multicellular organisms. Humans are the most complex of all multicellular organisms. All such organisms have billions of cells, tissues and different organ systems in the body.Full Answer >
In a cell, a food vacuole is a membrane-surrounded structure that stores food temporarily until the organism needs it. Another type of vacuole is very similar, but it stores waste products until they can be eliminated from the cell.Full Answer >
Cell division has three purposes for an organism: reproduction, growth and maintenance. For single-celled organisms, this is their direct and only method of reproduction, and it serves no other purpose. For multicellular organisms, cell division is a step in reproduction and is necessary for growth and maintenance.Full Answer >
