are human cells an organism
The cell (from Latin cella, meaning small room) is the basic structural, functional, and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate independently, and are often called the building blocks of life. The study of cells is called cell biology.Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.ells are the smallest unit of life that can replicate independently, and are often called the building blocks of life. The study of cells is called cell biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. An organism is any living thing, whether it is a plant, an animal or fungi. Some organisms (known as simple organisms) are composed of only one cell; others are composed of many more. These are multicellular organisms, human beings being one example.The first cells to ever be studied closely were those belonging to plants and animals.ome organisms (known as simple organisms) are composed of only one cell; others are composed of many more. These are multicellular organisms, human beings being one example. The first cells to ever be studied closely were those belonging to plants and animals. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell is a unicellular organism; and when it has more than one it is known as a multicellular organism.Most unicellular organisms are of microscopic size and are thus classified as microorganisms.umans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs. An organism may be either a prokaryote or a eukaryote. Prokaryotes are represented by two separate domains, the Bacteria and Archaea. Cells are to a living organism just as bricks are to a building; they are the basic structural units. Though a building is built of similar bricks, they are of different shapes and sizes.In a similar fashion, all organisms are made up of cells, though they differ from one another.ells are to a living organism just as bricks are to a building; they are the basic structural units. Though a building is built of similar bricks, they are of different shapes and sizes. In complex multicellular organisms, cells specialize into different cell types that are adapted to particular functions. In mammals, major cell types include skin cells, muscle cells, neurons, blood cells, fibroblasts, stem cells, and others.ells are the smallest unit of life that can replicate independently, and are often called the building blocks of life. The study of cells is called cell biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. All living things, large or small, plant or animal, are made up of cells. Most living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal. These living things are known as multicellular organisms.Water makes up about two thirds of the weight of cells.ost living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal. These living things are known as multicellular organisms. Examples are : - Humans-Animals-Fungi-Plants A single celled organism would be like an Amoeba and Bacteria Our organs are not separate organisms, all the pieces that make us human come together to make a Multi Celled Organism.:) I'm not sure if this helps answer your question.xamples are : - Humans-Animals-Fungi-Plants A single celled organism would be like an Amoeba and Bacteria Our organs are not separate organisms, all the pieces that make us human come together to make a Multi Celled Organism. :) I'm not sure if this helps answer your question. While the number of cells in plants and animals varies from species to species, humans contain more than 10 trillion (10 13) cells. Most plant and animal cells are visible only under the microscope, with dimensions between 1 and 100 micrometres.ells are the smallest unit of life that can replicate independently, and are often called the building blocks of life.

O Rahilly addresses human organisms, their distinction from just cells, and their growth and development in his first chapter dealing with the science of human embryology. As O Rahilly documents, the immediate product of human sexual reproduction is a single-cell organism :here is a critical difference between an organism and its constituent cells. Even common dictionaries understand this, e.g., In biology and ecology, an organism is a living being. The phrase complex organism describes any organism with more than one cell. May serve a specific function within the organism. Examples-blood cells, nerve cells, bone cells, etc. LEVEL 2 - Tissues. Made up of cells that are similar in structure and function and which work together to perform a specific activity. Examples-blood, nervous, bone, etc.n unicellular (single-celled) organisms, the single cell performs all life functions. It functions independently. However, multicellular (many celled) organisms have various levels of organization within them. Individual cells may perform specific functions and also work together for the good of the entire organism.
