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.
The system of intricate passageways inside cells is called the endoplasmic reticulum (ER). It plays a key role in protein and lipid synthesis, transport, and storage within the cell. The ER can be classified into rough ER (with ribosomes attached) and smooth ER (lacking ribosomes).
cells grow in predictable ways
Lock and key and size
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.
usually updates the operating system in small ways, normally small changes to it
lightning & bacterial action (nitrogen fixers).
All cells have DNA
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.
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.
Amino acids, proteins and DNA.
