4 CONCEPTS OF THE CELL THEORY
A. A cell is the basic structural and functional unit of living organisms.
B. The activity of an organism depends on the collective activities of its cells.
C. According to the principle of complementarity, the biochemical activities of cells are dictated by the relative number of their specific subcellular structures.
D. Continuity of life has a cellular basis.
According to the _____, the biochemical activities of cells are dictated by the relative number of their specific subcellular structures.
THE PRINCIPLE OF COMPLEMENTARITY
Is the basic structural and functional unit of living organisms.
A CELL
4 elements most cells are composed of
CARBON
HYDROGEN
OXYGEN
NITROGEN
The primary basic element of molecules
CARBON
Most important element
CARBON
Component of most organic molecules and influences body fluid
HYDROGEN
Most important genetic materials
NITROGEN
Major component in organic and inorganic molecules
OXYGEN
Anatomy of the Cell (3)
a. Cells are not all the same
b. All cells share general structures
c. All cells have three main regions (nucleus, cytoplasm, plasma membrane)
What are the 3 main regions of cell
NUCLEUS
CYTOPLASM
PLASMA MEMBRANE
It is the headquarter or control center of the cell
NUCLEUS
It is called the “blueprint”
NUCLEUS
It is where DNA located
NUCLEUS
TYPES OF CELL (7)
- Cells that connect body parts
- Cells that cover and line body organs
- Cells that move organs and body parts
- Cell that stores nutrients
- Cell that fights disease
- Cell that gathers information and controls body functions
- Cell of reproduction
Importance of red blood cells
TRANSPORT OXYGEN
during___ is the vital role of white blood cells
INFECTION
A cell that gathers information and controls body functions
NERVE CELLS
Reproduction cell of male
SPERM
Reproduction cell of female
OOCYTE
Sequence of body tissue
Cells when gathered together formed TISSUES, tissues when gathered together formed ORGANS, organs when gathered together formed SYSTEMS, systems when gathered together formed an ENTIRE HUMAN BEING
is collectively gathered and form particular tasks
CELLS
Groups of cells with similar structure and function
TISSUES
4 primary types of tissues
- Epithelial tissue (epithelium)
- Connective tissue
- Muscle tissue
- Nervous tissue
