The cells Flashcards
What is a cell?
Is the basic structural and functional unit of all living things
Name the three principles of cell theory
-all living organism are made of one or more cells
-all cells are basic unit of structure and organization
-cells arise only from previously existing cells
What is an organelle?
specialized membrane bound structures that carry out specific cell functions in different parts of the cell at the same time
What is a eukaryotic cell?
are defined as the cells with a nucleolus and other organelles that are bond by membranes
What is a eukaryotic cell?
are defined as the cells with a nucleolus and other organelles that are bond by membranes
Explain the role of mitochondria in the cell.
ere the energy generators of the cells
Explain the role of the chloroplasts in the cell
organelles that capture light energy and convert it to chemical energy through a process called photosynthesis
Explain the role the ribosomes and endoplasmic reticulum in the manufacturing of proteins.
free floating ribosomes produce proteins for use within the cytoplasm of the cell
ER is a membrane system that of folded sacs and interconnected channels that serves as the site for protein
Laws of thermodynamics
energy can’t be destroyed or created
energy can be converted from one form to another
Metabolism in photosynthesis and cellular respiration.
all of the chemical reactions in a cell are metabolism
ATP, the unit of cellular energy
is a multistructure storehouse of chemical energy
main part in anaerobic respiration
glycolysis
Name and describe the non-optical microscopes.
Diffraction apparatus is a type of microscope that uses a beam of light to see very small objects.
types of fermentation
atic lacid, alchohol
