What is true about the types of chemical elements in living cells?
all cells contain the same key elements, such as carbon, nitrogen, and oxygen.
Do all plant cells a nucleus?
Some cells like seive tube elements lack.Other cells have a nucleus.
What are the three elements of cell theory?
1. All living things are made up of one or more cells. 2. Cells are the basic living units within organisms. The chemical reactions of life take place within the cells. 3. All cells arise from pre-existing cells through the process of cell division.
Do all formed elements arise from a common type of stem cell called hemocytoblast?
Technically yes they are because hemocytoblast stem cells create Myeloid stem cells and Lymphoid stem cells which produce all of the formed elements (white and red blood cells).
Red blood cells megakaryocyte eosinophil basophil monocyte neutrophil and lymphoctes are all examples of what?
formed elements
What are 3 elements that plant cells have and animal cells do not?
nothing

What is the correlation of a period number with the elements of that period?
all the elements in period 1 have one energy level, all the elements in period 2 have two energy levels, all the elements in period 3 have 3 energy levels... and so on
How are the formed elements of blood related?
The formed elements of blood are related in that they are all the cells or cell fragments that comprise the solid portion of blood, and they arise from the same type of stem cell. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
What are the 3 basic principles of the cell theory?
1. all cells come from existing cells 2. cells are the basic unit of life 3. all living organisms are composed of cells
What is meant by chemical disaster?
Life threating to all forms of living cells, and to the elements of life.
