The Cell Theory
List the 4 tenets of the cell theory
Cells are the smallest structures found within an organism
All living organisms are made of one or more cells
All cells are made from preexisting cells
The basic functional unit of all living organisms is the cell.
Interconnected network of membranes out from the nuclear membrane
Endoplasmic Reticulum
Fluid that holds the organelles in place
Cytoplasm
Holds cells together to from tissues in the body and protects cell membrane
Extracellular Matrix
Diffusion is the movement of particles
from areas of greater concentration to areas of lesser concentration
Known as the Father of Microbiology
Antoine van Leuwenhoek
A general term for an enclosed membrane that transports molecules within it
Vesicle
Organelles that lacks ribosomes
Smooth ER
Type of junction that prevents leaks
Tight junction
What chemical process occurs in the cell organelle called the mitochondria?
Respiration
Robert Hooke observed what object underneath a microscope to coin the term "cell"
Cork
Membrane-bound sacs of digestive enzymes
Lysosomes
Numerous ribosomes embedded in its membrane
Special protein structures that provide structural stability and facilitate communication between cells
Junctions
A cell produces a protein that will be used by other cells When the cell releases the protein into the extracellular fluid, what function has it performed?
secretion
List at least 3 scientist who contributed to the development of the cell theory
Robert Hooke, Henri Dutrochet, Barthelemy Dumortier, Antoine van Leuwenhoek
Harnesses energy from sunlight, converting it into chemical potential energy stored in sugar molecules as glucose to be converted to ATP
Chloroplasts
Processes (releases) energy
Site of cellular respiration
Mitochondria
Type of junction that facilitates rapid communication between coordinated cells
GAP junctions
Small storage containers for water and other small molecules
Vacuoles
Gives structure and strength to plants and prokaryotic cells; keeps cell from swelling to bursting point and protects from outside damage; also gives plants cells a rigid shape
Cell Wall
Type of junction that holds tough muscle or skin tissues together
Desonomes
