digestive system
the endoplasmic reticulum
Digestion changes food into substances which the body can use. This is a series of chemical changes where the food molecules react with water in the presence of enzymes to produce smaller, soluble molecules.saliva in the mouth contains enzymes that break some starches down to glucosehydrochloric acid and enzymes in the stomach denature proteins and break them down to amino acidsenzymes in the small intestine break fats down to fatty acidsenzymes in the small intestine break starches down to glucosebacteria in the large intestine break complex carbohydrates down to glucoseThe intestines absorb glucose, amino acids, and fatty acids to the blood stream.
Plant cells have chloroplasts. They have glyoxisomes and photosynthetic

One reason that stem cells are important is due to human development from stem cells. As such, an understanding of their unique attributes and control can teach us more about early human development. Diseases such as cancer are thought to result from abnormal cell proliferation and differentiation. This means that an understanding of where things go 'wrong' in stem cell division and thus lead to cancer can help us find ways to prevent the dysfunctional changes or employ effective ways to treat them with targeted drugs.
Ways that the body changes food to a form that is usable by all its cells is floor 8 which is the digestive system. Ways the body gets rid of its waste products is floor 4 which is the urinary or excretory system.
the endoplasmic reticulum
usually updates the operating system in small ways, normally small changes to it
All cells have DNA
lightning & bacterial action (nitrogen fixers).
Microbiologists study life processes that occur on the cellular level. This can mean the diagnosis and treatment of diseases caused by bacteria and viruses. It can also include studying the microscopic changes in plant and animal cells -- these can affect the ways that cells work, or how they affect other cells.
Since life as we know it is cellular, any biological system has "anything to do" with cells :) Nervous system is no exception: it's tissues (e.g. brain) consist of heavily interlinked groups of cells, called neurons, which main function is creating and transporting neural impulses in different ways, involving complicated chemical and electro-chemical processes.
Amino acids, proteins and DNA.
Some ways in which material may move in and out of cells are diffusion and also osmosis.
