Cell Structure
Powerhouse of the cell
Basic unit of life
What is a cell?
Multicellular organism
What is a eukaryote?
Form of diffusion that requires energy
What is active transport?
Fluid-like interior of a cell which surrounds organelles
What is the cytosol?
Process that allows cells to come from other cells
What is cell division
Eukaryotes have bound organelles, while prokaryotes have nucleoids and plasmids (DNA is not bound )
What is the difference between eukaryotic and prokaryotic structures?
Movement from high concentration to low concentration
What is a concentration gradient?
After protein synthesis, proteins come here to get modified and transported
Idea that life could arise from non-living matter
Complex eukaryotes descended from simpler prokaryotes
What is endosymbiotic theory?
Entry and exit in the cell
What role do phospholipids play in the cell membrane?
The Krebs Cycle happens here
What is the mitochondrial matrix?
Man who coined the term cells
Who is Robert Hooke
Eukaryotic organelles that were once primitive bacterial cells
What is the mitochondria and chloroplast?
The sodium potassium pump is an example of active transport
What type of diffusion is the sodium-potassium pump?
After leaving the Golgi Apparatus as a vesicle, these break down waste
What is a lysosome?
Discovered that all animals and thus all living things are made of cells
Who is Theodor Schwann?
Cell walls provide more structure to plant cells and are usually made of cellulose and chitin, while cell membranes are only found in animal cells and consist of phospholipids, glycolipids, channel proteins, and glycoproteins
What is the difference between cell membranes/walls in plant and animal cells?
The import of materials into a cell (eg pinocytosis)
What is endocytosis?
