Organelles
Serves as the cell's boundary from its environment and controls what goes in and out of the cell.
What is the Cell Membrane?
The spreading out of molecules across a membrane until equilibrium is reached.
What is Simple Diffusion?
Research has shown that uncontrolled cell growth and development can lead to
What is cancer?
The movement of water across a semipermeable membrane.
What is osmosis?
Cells often store materials like water, salts, proteins, and carbohydrates in sac-like structures.
What are Vacuoles?
What is a chloroplast?
A type of movement across a membrane that requires no extra energy by the cell because molecules move from high concentration (squished together) to low concentration (spread out) areas down the concentration gradient.
Passive Transport
The cell grows, duplicated organelles, and copies DNA.
What is Interphase?
The process of using vesicles to export materials out of the cell.
Exocytosis
Substances known to produce or promote cancer.
What are Carcinogens?
Digests foreign substances and worn out cell parts.
What is Golgi Apparatus?
The process to facilitate the diffusion of molecules that normally couldn‘t pass through the cell membrane (ex: Glucose).
What is Facilitated Diffusion?
Undifferentiated cells that can become differentiated into one or more types of specialized cells.
The concentration is equal on both sides of the membrane.
What is isotonic?
An organelle is critical for cell division
What are Centrioles?
An organelle in BOTH plant and animal cells that produces energy (ATP).
What is Mitochondria?
Moves particles against the concentration gradient from areas of lower concentration to higher concentration.
Active Transport
Cancer cells that break away from the tumor and move to other parts of the body, can cause tumors in other parts of the body.
What are malignant tumors?
Water will move into the cell, causing the cell to swell.
What is a Hypotonic Solution?
Even primitive cells, like the prokaryote, can carry out the functions of life.
What is Cell Theory?
Structures shaped like small oars that beat in unison to move the cell or liquid around it.
What is Cilia?
This process occurs when the cell uses energy to bring something in from outside the cell.
What is Endocytosis?
A cell receives a signal from the cell's own nucleus to divide.
What is Internal Regulation?
An animal cell placed in a solution of salt water from the ocean, the water moves out of the cell.
What is hypertonic solution?
This level of organization is represented by a group of different tissues working together to perform a complex function.
What are organs?
