Cell Structure
Plasma membrane, cytoplasm, and nucleus
What are the three main parts of a cell?
Doesn't require ATP
What is passive cellular transport?
The moving of ions against the concentration gradient
What is an ion pump?
Mitochondria
What is the powerhouse of the cell?
The stage which a cell spends most of its life.
What is interphase?
Hair-like projections that move extracellular fluid
What are cilia?
When the solution inside a cell has the same concentration as outside the cell
What is isotonic?
A vesicle is created and a substance is taken into the cell
What is pinocytosis?
studded with ribosomes, which produce protein
What is rough ER?
A sperm or egg cell
What are gametes?
Not found in a mature red blood cell.
What is a nucleus?
The ability of an extracellular solution to change the amount of water within a cell.
What is tonicity?
Engulfing bacteria into a vesicle
What is an example of phagocytosis?
Enzymes within store calcium and produce lipids
What is a function of smooth ER?
When the cell doubles its DNA so it can pass on two complete sets.
What is interphase?
Projections from plasma membrane that increase absorption of nutrients
What are microvilli?
The concentration of particles in a solution
What is the osmotic pressure?
Usually stimulated by cell membrane receptor signal from hormone or change in charge
What is Exocytosis?
Will form a vesicle that is transported to plasma membrane by pinching off a piece of itself.
What is the golgi apparatus?
The stage when chromosome pairs are visible under a microscope
What is metaphase?
Allows entire cell to move during mitosis.
What are microfilaments?
When substances move through protein channels or by carrier proteins
What is facilitated diffusion.
Condition of being inside of a cell
What is endocytosis?
Organelles attach to these to move around within the cell
What are microtubules?
When cells cannot be replaced because they don't go through mitosis
What is amitosis?
