modern cell theory
All known living things are made up of one or more cells.
All living cells arise from pre-existing cells by division.
The cell is the fundamental unit of structure and function in all living organisms.
The activity of an organism depends on the total activity of independent cells.
Energy flow (metabolism and biochemistry) occurs within cells.
Cells contain DNA which is found specifically in the chromosome and RNA found in the cell nucleus and cytoplasm.
All cells are basically the same in chemical composition in organisms of similar species

All cells contain a nucleus for the storage of genetic material. (T/F)
False.
Modern cell theory does not state that all cells contain a nucleus for storage of genetic material. Prokaryotes cells do not contain a nucleus. Instead, their genetic material is stored in the cytosol.

The deregulation of apoptosis may lead to the development of various diseases. Which of these may develop from insufficient apoptosis?
A. Alzheimer's disease
B. Cancerous growth
C. Parkinson's disease
D. Turner Syndrome
E. Huntington's disease

Cancer is the result of uncontrolled cell proliferation. Apoptosis is programmed cell death, which functions both in normal cell development but is also a necessary part of destroying damaged and mutated cells that multiply uncontrollably. If apoptosis were to be deregulated, uncontrolled cell growths, including cancer, would be an expected result.
