Cell Theory & Living Things
According to cell theory, this is the most basic functional unit of life.
A cell
This large organelle contains the cell's DNA.
Nucleus
This is the primary unit used to measure pressure, abbreviated as Pa.
Pascal
This is the speed of light through space, measured in metres per second.
300 000 000 m/s
This is the range of seven broad colours - from red to violet - that then human eye can naturally detect.
The visible spectrum
The four basic characteristics shared by all living things.
Growing, moving, reacting, and reproducing
This organelle acts as the outer skin that controls what goes in and out of the cell.
Cell membrane
This is the mathematical formula used to calculate pressure.
Pressure = force / area
This property states that light travels in straight lines and is the reason shadows are formed.
Rectilinear propagation
This property of a wave measures the number of repetitive vibrations or cycles that occur per second.
This structural hierarchy explains how individual units scale up to form an entire organs (basic to most complex).
Cells, tissues, organs, organ systems
This organelle is found only in plant cells and gives plant cells their boxy shape
Cell wall
This law states that pressure applied to an enclosed fluid is transmitted with equal force throughout the entire container.
Pascal's law
This type of reflection happens when light hits a smooth surface like a mirror, causing all rays to bounce off at the same angle to form an image.
Specular reflection
This rule describes the mathematical relationship between a wave's frequency and its wavelength.
The higher the frequency, the shorter the wavelength
These two body systems work closely together when your small intestine breaks down food into nutrients and transfers them into blood vessels to feed your cells.
Digestive and circulatory systems
Operating like the cell's power plants, these organelles produce energy for the cell.
Mitochondria
This specific type of system transmits an applied force through a liquid, such as the mechanism found in a dentist's chair or heavy machinery.
Hydraulic system
This property describes the bending of light as it passes from one substance into another, like a straw looking bent in water.
Refraction
This type of radiation is commonly used for medical imaging, but too much exposure over time can cause cancer.
X-rays
When you are cold, your nervous system interacts with this body system to cause rapid contractions known as shivering.
Muscular system
Unlike animal cells which have small versions of these storage units, a plant cell features one massive one filled with water to keep the plant firm.
Vacuole
This happens to the pressure inside an rigid container, like a spray can, if the temperature is increased.
Pressure increases/Could explode
This term describes a substance that is cloudy, letting light pass through but not enough to see through clearly.
Translucent
This high-energy type of radiation is used in therapy to treat cancer, though high exposure can lead to radiation sickness.
Gamma rays
