RER + SER
What is a smooth ER?
Smooth: An organelle found in both animal cells and plant cells
Known as the ____ of the cell
Powerhouse
What is diffusion?
Diffusion is the random movement of molecules/particles from an area of high to low concentration
Who coined the term cell?
By looking at what
Robert Hooke
A cork
What is plasmolyosis?
Drop in turgor pressure (causes wilting)
What does the Rough ER have that the Smooth ER does not?
Ribosomes
Mitochondria produces what?
Produces most of the chemical energy needed to power the cell's biochemical reactions
What does high concentration create?
Who coined the term "animalcule"? + What did he observe to make this term
Anton Von Leeuwenhoek + Pond water
Turgor pressure is the force within the cell that pushes the plasma membrane against the cell wall.
It is also called hydrostatic pressure, and is defined as the pressure in a fluid measured at a certain point within itself when at equilibrium.
What is the Rough ER
Rough: A structure found within the cytoplasm of eukaryotic cells.
What is the general role of the Mitochondria?
The general role of mitochondria in the cells is to perform cellular respiration, it takes nutrients breaks them down, and then turns them into energy.
Osmosis: Isotonic Solution:
An isotonic solution is any external solution that has the same solute concentration and water concentration compared to body fluids
Who found out that all plants have cells?
Mattais Schleiden
What is equilibrium?
A state in which opposing forces or actions are balanced so that one is not stronger or greater than the other.
How can you tell the difference between rough and smooth ER?
rough has ribosommes attached and smooth is smooth
What is the main function of the mitochondria?
The main function of mitochondria is oxidative phosphorylation
What is Osmosis?
Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
Who found out that all cells come from pre-existing cells?
Rudolph Virchow
What is a concentration gradient?
A measurement of how the concentration of something changes from one place to another.
What are the functions of both Smooth and Rough ER?
Smooth ER: Helps synthesize and concentrate various substances needed by the cell. (Lipids)
Rough ER: Produces proteins for the rest of the cell to function.
What is oxidative phosphorylation?
oxidative phosphorylation is a cellular process that harnesses the reduction of oxygen to generate high-energy phosphate bonds in the form of adenosine triphosphate (ATP).
In simple works oxidative phosphorylation creates ATP
Osmosis: Hypotonic Solution
A hypotonic solution is a solution that has a lower concentration of solute compared to the cell.
What is cell theory?
Cell theory is that all cells are made from exisiting cells, all the plants and animals are composed of cells and the cell is the basic unit of life.
What is a semi-permeable membrane?
semi-permeable membrane allows only some stuff to pass through
