Cell Structure
The organelle that controls all the cell's activities
The movement of molecules from an area of higher concentration to an area of lower concentration
Diffusion
Material found in the nucleus that contains genetic information
DNA
Circulatory system
This system transports blood, nutrients, gases and wastes
What type of cancer can you develop from over-exposure to sunlight?
Melanoma
The organelle that creates energy for the cell
mitochondria
Sometimes, diffusion requires a "door" in th membrane where proteins make the passage of the molecule possible
Facilitated diffusion
The period of growth and DNA replication within the cell cycle; the cell spend most of its time in this stage
Interphase
How are cells organized in a hierarchy?
Cells-> Tissues-> Organs-> Systems-> Organism
Tests used to detect cancer at an early stage of the disease to treat it more effectively
Cancer Screening
A tough, rigid structure outside of the cell membrane that only plants have
Cell Wall
The substance that is dissolved
Solute
What are the 3 stages of the cell cycle?
Interphase, Mitosis, Cytokinesis
This type of tissue lines the surface of the body and acts as a body covering and between the internal organs
This technology transmits wavelength of electromagnetic radiation to produce an image of hard tissue (ex. bone)
X-Ray
The organelle responsible for making proteins
Ribosomes
The movement of water across a membrane
Osmosis
The phase of mitosis in which the centromere splits apart and the chromatids are pulled to opposite ends of the cell by spindle fibres
Anaphase
Most of the digestion takes place here and nutrients are absorbed
Small Intestines
This technology transmits sound waves to produce an image of soft tissue
Ultrasound
What is the difference between a plant cell and animal cell? (List the organelles)
Cell wall, chloroplasts, vacuole
Cells divide because...
there is a limit to how large they can grow
Cells with abnormal genetic material that are dividing uncontrollably and can spread to other parts of the body
Cancer
An unspecialized cell that can become any one of an organism's body cells and can be used for research
Stem Cells
Why should pregnant women avoid technologies such as X-rays and CAT scans?
Too much radiaition
