Organelles
This organelle is known as the powerhouse of the cell
What is Mitochondria
True or False: A cell is most efficient when there is a lower ratio of surface area to volume
What is False
The heads of the phospholipid bilayer are _________________ meaning "Water-loving"
Hydrophilic
This is the process by which unspecialized cells become more specialized to carry out distinct functions
What is Differentiation
This type of tissue is described by being highly cellular with no vasculature
What is epithelial tissue
This organelle makes proteins
What is a ribosome
What part of the cell cycle is known as the division of the nucleus
What is mitosis
These proteins are proteins embedded in the cell membrane
What are integral proteins
These cells are unspecialized and can divide without limit as needed and can differentiate into specialized cells. All cells start out as this
What is a stem cell
This tissue is excitable, and is capable of sending and receiving electrochemical signals
What is Nervous Tissue
This organelle is the barrier or gateway of the cell
What is a cell membrane
This phase describes the time between divisions, and is a long growth stage for the cell?
What is interphase
This is known as movement of a substance across a membrane using ATP
What is active transport
This class of proteins bind to specific genes on the DNA molecule during transcription and lead to cell specialization
What are Transcription Factors
This type of tissue functions to support and protect, transport, as well as store free energy
What is Connective Tissue
This organelle is involved in mitosis and spindle fibers attach to them.
What is a centriole
During this phase of mitosis, spindle fibers pull sister chromatids apart, and individual chromatids move to opposite poles of the cell
What is anaphase
Passive transport occurs due to this, a difference in concentration of a substance across a space
What is a Concentration Gradient
This is a group of cells found together in the body that share a common function and common embryonic origin
What are tissues
This type of muscle tissue has no striations, and is responsible for moving food down the digestive tract
What is Smooth Muscle
This organelle is the packaging center of the cell.
What is the Golgi Complex
What is genetically identical
This type of solution has a higher concentration of solutes outside of the cell, water moves out of the cell and the cell shrivels
What is a Hypertonic solution
This type of membrane contains both epithelial tissue and connective tissue. An example is the Serous Membrane?
What are epithelial membranes
This classification of epithelial tissue is characterized by a flat cell that has multiple layers
What is Stratified Squamous Epithelium
