Cell Organelles
Plant cells perform photosynthesis here.
Where is the chloroplast?
From the Greek words for "same" and "steady," this term was coined by Dr. Walter Cannon in 1930 and refers to any process that living things use to actively maintain fairly stable conditions necessary for survival.
What is homeostasis?
Adenosine triphosphate, aka this, is required to move molecules against the concentration gradient.
What is ATP?
This extra ingredient is not needed.
What is energy?
The simple diffusion of water across a cell membrane.
What is osmosis?
Ribosomes can be found (not made) here.
Where are the cytoplasm and rough ER?
Homeostasis is maintained primarily by this particular mechanism.
What is a negative feedback loop?
Active transport cannot occur without assistance, therefore this is required in addition to energy.
What is a transport protein?
This is defined as the net movement of molecules or particles from areas of higher concentration to areas of lower concentration.
What is diffusion?
Solutions that contain the same concentration of water and solutes as the cell cytoplasm.
What are isotonic solutions?
Three organelles not found in an animal cell.
What are cell wall, chloroplast, and central vacuole?
This condition disrupts the negative feedback mechanism in the pancreas where insulin is produced.
What is diabetes?
The release of neurotransmitters from nerve cells is an example of this.
What is exocytosis?
The easy passage of molecules into and out of the mitochondria is accomplished via this.
What is simple diffusion?
This type of solution is given when the cell is dehydrated and fluids need to be put back intracellularly.
What is a hypotonic solution?
Organelle used to move fluid.
What is cilia?
Processes that do not need to maintain status quo usually involve this mechanism.
What is a positive feedback loop?
This form of endocytosis is seen when white blood cells engulf foreign substances such as bacteria and viruses.
What is phagocytosis?
Because glucose molecules are too large to cross a cell membrane unaided, these are needed to accomplish this type of transport.
What are channel/carrier proteins and facilitated diffusion?
This type of solution can be utilized in the treatment of heavy fluid loss.
What is a hypertonic solution?
These organelles are critical for cell division in animal cells.
What are centrioles?
This hormone is responsible for increasing uterine contractions thus increasing cervical pressure in a positive feedback loop resulting in the birth of a child.
What is oxytocin?
This is the principal mechanism for active ion transport across the cellular membrane of cardiac tissue.
What is the sodium-potassium pump?
These 2 chemical gases use passive transport to travel across cell membranes.
What are oxygen and carbon dioxide.
The maintenance of constant osmotic pressure in the fluids of an organism by the control of water and salt concentrations.
What is osmoregulation?
