id say the plants and animals are multi-celled and the others are single-celled. also cell specilization could be a difference.

An animal cell is a form of eukaryotic cell which make up many tissues in animals. The animal cell is distinct from other eukaryotes, most notably plant cells, as they lack cell walls and chloroplasts, and they have smaller vacuoles. Due to the lack of a rigid cell wall, animal cells appear to be circular (though are often deformed by surrounding cells) under microscopes - in three dimensions the cells are normally spherical.

THe heart is made up of two pumps; one that contains oxygenated blood, and one that contains deoxygenated blood...they are divided by this thick wall called a septum...each half is made up of a ventricle and an atrium...that question was on my science quiz today!!!

Two or more atoms make a molecule\nMillions and millions of molecules make up a cell.

Cell theory history\nIn 1838, the botanist Matthias Jakob Schleiden and Theodor Schwann, a physiologist discovered that both plant and animal cells had nuclei. From this realization, they surmised that all living things were composed of cells. In 1839, Schwann published 'Microscopic Investigations on the Accordance in the Structure and Growth of Plants and Animals', which contained the first statement of the cell theory.\n\nSchwann and Schleiden's statement of the cell theory was:\n\nCells are the unit of structure, physiology, and organization in living things. \nCells are both a distinct entity and a building block in the construction of organisms. \nCells form by spontaneous generation.

Epithelial tissue consists of cells that form membranes, which cover &\nline body surfaces. In addition, epithelial tissue forms glands, which\neither secrete chemicals outside the membrane (exocrine glands) or\nsecrete chemicals (hormones) into the blood (endocrine glands)\n\nThe type found in the trachea of mammals is pseudostratified surface epithelium and is composed of differentiated cell phenotypes including basal, secretory and ciliated cells.

In biology, an organ (Latin: organum, "instrument, tool") is a group of tissues that perform a specific function or group of functions. Usually there is a main tissue and sporadic tissues. The main tissue is the one that is unique for the specific organ. For example, main tissue in the heart is the myocardium, while sporadic are the nervous, blood, connective etc. (Wikipedia.org)\n\nIn zootomy and dermatology, skin is an organ of the integumentary system made up of multiple layers of epithelial tissues that guard underlying muscles and organs. As the interface with the surroundings, it plays the most important role in protecting against pathogens. Its other main functions are insulation and temperature regulation, sensation and vitamin D and B synthesis. Skin is considered one of the most important parts of the body.(Wikipedia.org)\n\nPretty much the skin is considered an organ because it is a group of tissues speciallizing in a certain task / tasks. For example the skin regulates temperature by using the sweat glands to produce sweat - sweat evaporates and cools the body.

chemical, cellular, tissue, organ, organ system, organism\n\nchemical - stuff that comprises a cell and the processes within\ncellular - smallest unit of sustained life\ntissue - group of cells working together\norgan - a lot of tissue\norgan system - several organs that work together\norganism - a person could be considered an organism.

I think it's protein. Because most of the human organ need protein to be form. The human organ, including heart are consist of cells, and they need protein to regenerate, I think this also happens when they were formed in fetus period.

All matter is made up of atoms. God put atoms together to make everything.

Neither.\nThey are composed largely of keratin, very closely related to the keratin found in skin.  They are made up of cells, but living ones, not dead.

1)  The cell is the unit of structure, physiology, and organization in living things. \n   2)  The cell retains a dual existence as a distinct entity and a building block in the   construction of organisms. \n   3)  Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).\n\nKeep this as hint and do your homework

G'day Joanne F,\n\nThank you for your question.\n\nIt is essential if you are studying medicine to have a good understanding of how cells and tissues work. It is also useful to know how particular cells such as blood cells work.\n\nRegards

Your body makes cells by the process called mitosis.\n\nHere's a website on mitosis:\nhttp://www.cellsalive.com/mitosis.htm

The skin. Although it is tissue, organs are just groups of tissues.

No.\n\nSome things can never be made up.
