You are watching: Why do complex organisms need specialized cells

NSES Content conventional CLife Science: structure and duty in life systemsGrades 5-8, page 156Specialized cells perform dedicated functions in multicellular organisms.Groups of specialized cells cooperate to type a tissue, such as a muscle.Different organization are subsequently grouped with each other to type larger functionalunits, dubbed organs. Each form of cell, tissue, and organ has actually a distinctstructure and set of functions that serve the organism as a whole.
�Benchmark 5C The living Environment:CellsGrades 3-5, web page 111Microscopes do it feasible to view that living things are made mostlyof cells. Part organisms are made that a repertoire of comparable cells thatbenefit indigenous cooperating. Some organisms" cells vary significantly in appearanceand perform very different functions in the organism.Benchmark 5C The living Environment:CellsGrades 6-8, page 112All living things space composed the cells, from simply one to plenty of millions,whose details usually space visible just through a microscope. Differentbody tissues and also organs are comprised of various kinds that cells. The cellsin similar tissues and organs in other animals are similar to those inhuman beings but differ somewhat from cells discovered in plants.Benchmark 5C The life Environment:CellsGrades 6-8, page 112Cells continually division to make an ext cells because that growth and also repair.Various organs and also tissues function to offer the needs of cells for food,air, and waste removal.Benchmark 5C The living Environment:CellsGrades 6-8, page 112Within cells, plenty of of the simple functions that organisms--such as extractingenergy indigenous food and getting rid of waste--are lugged out.
