Cells 1
Cells Vary in
Size , shape, color and function
The production department of the cell
The cytoplasm
cells are composed of four elements:
Carbon
Hydrogen
Oxygen
Nitrogen
I am the organelle that makes energy.
mitocondria
Basic units of living matter (life)
cells
Outer surface of the cell
cell membrane
Phospholipid arrangement in the plasma membrane
_________ (“water loving”) polar “heads” are oriented on the inner and outer surfaces of the membrane
Hydrophilic
Cells that connect body parts 2 types
Fibroblast, Erythrocyte
Basic parts of most cells
3 things
Nucleus, Cytoplasm, Cell Membrane
division of the nucleus
mitosis
Phospholipid arrangement in the plasma membrane
(“water fearing”) nonpolar “tails” form the center (interior) of the membrane
Hydrophobic
_____________is a series of changes the cell experiences from the time it is formed until it divides
Cell life cycle
Where is the nucleus located?
In the cytoplasm
Cells receive nutrients for growth and reproduction
metabolism
Fluid that suspends other elements and contains nutrients and electrolytes
Cytosol
Protein synthesis involves two major phases:
Transcription
Translation
The center of the cell activities
nucleus
division of the cytoplasm
Cytokinesis
According to this principle, the biochemical activities of cells are dictated by their structure (anatomy) which determines their function (physiology)
the principle of complementarity
The human body has about how many cells
50- 100 trillion
