A rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria.
What is the cell wall?
100
It is often the largest organelle in the cell. It is surrounded by a membrane and functions to hold materials and wastes.
What is the vacuole?
100
The framework of the body, consisting of bones and other connective tissues, which protects and supports the body tissues and internal organs.
What is the skeletal system?
100
Are found at the ends of long bones.
What are spongy bones?
200
An organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material.
What is the nucleus?
200
Any organized or specialized structure within a living cell.
What is an organelle?
200
Will allow certain molecules or ions to pass through it by diffusion.
What is the cell membrane?
200
The network of nerve cells and fibers that transmits nerve impulses between parts of the body.
What is the nervous system?
200
The body part that gases, such as oxygen and carbon dioxide, pass into or out of the blood.
What is the lungs or alveoli?
300
Work to convert light energy of the Sun into sugars that can be used by cells.
What is the chloroplasts?
300
They lack a distinct cell nucleus and their DNA is not organized into chromosomes. They also lack the internal structures bound by membranes called organelles, such as mitochondria.
What is the prokaryotic cell?
300
A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
What is osmosis?
300
An organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body.
What is the muscular system?
300
Helps our sense organs work together
What are nerves?
400
They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.
What is the mitochondria?
400
The cells of eukaryotes also contain an endoplasmic reticulum and numerous specialized organelles not present in prokaryotes, especially mitochondria, Golgi bodies, and lysosomes.
What is the eukaryotic cells?
400
Is a form of active transport in which a cell transports molecules (such as proteins) into the cell
What is endocytosis?
400
The set of organs that allows a person to breathe and exchange oxygen and carbon dioxide throughout the body.
What is the respiratory system?
400
The main function of muscle cells.
What is to allow movement?
500
Is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.
What is the cell membrane?
500
A green pigment, present in all green plants and responsible for the absorption of light to provide energy for photosynthesis.
What is the chlorophyll?
500
The spreading of something more widely.
What is diffusion?
500
The system that circulates blood through the body, consisting of the heart, blood vessels, and blood.
What is the circulatory system?
500
The body part plays the largest role in controlling the nervous system
