All About Cells
your skin cells do this to divide (2n = 46 chromosomes in each of your skin cells)
mitosis
Organisms that can reproduce through fruiting bodies and can send out spores. They are some of the largest organisms in the world!
fungi
The rate at which an object changes its position in a specific direction
velocity
The process by which an oceanic tectonic plate sinks under another plate into Earth's mantle
subduction
The specific role, position, or "functional job" an organism plays within its ecosystem, including how it uses resources and interacts with biotic (living) and abiotic (non-living) factors
niche
A two-step cell division process in sexually reproducing organisms that reduces the chromosome number by half, producing four genetically unique haploid gametes from one diploid parent cell
Meiosis
The green photosynthetic pigment found chiefly in the chloroplasts of plants
chlorophyll
The natural tendency of an object to resist changes in its state of motion
Inertia
The point on Earth's surface directly above the focus of an earthquake
epicenter
The evolutionary process by which populations evolve to become distinct, reproductively isolated species
speciation
The metabolic process where cells break down glucose and other organic molecules in the presence of oxygen (aerobic) to produce energy in the form of ATP
cellular respiration
The biochemical process by which some organisms convert light energy (usually from the sun) into chemical energy (ATP)
photosynthesis
The rate of change of an object's velocity with respect to time, involving a change in speed, direction, or both
acceleration
An instrument that constantly records ground movements.
seismograph
Remnants of structures that were functional in ancestors but are now reduced or non-functional.
Vestigial Structures
These are membrane bound organelles that generate most of the cell's supply of energy (ATP)
mitochondria
The energy currency/molecule that we use in our cells!
adenosine triphosphate (ATP)
The branch of physics that studies the relationships between heat, work, temperature, and energy
thermodynamics
A water wave cause by an earthquake, volcanic eruption or landslide.
tsunami
A self-regulating process by which biological systems maintain a stable, relatively constant internal environment despite changes in external conditions
homeostasis
A network of membranes, tubes, and sacs within a cell that acts as a transport and production factory, responsible for making, folding, and exporting proteins and lipids. (Hint: there are two types)
endoplasmic reticulum
The molecule that carries genetic information for the development, function, and reproduction of all known living organisms
deoxyribonucleic acid
One of the four fundamental forces of nature, describing the interactions between electrically charged particles and the magnetic fields they create
electromagnetism
The layer in Earth's upper mantle and directly under the lithosphere in which rock is soft and weak because it is close to melting.
asthenosphere
A type of symbiotic relationship in biology where one organism benefits, while the other is neither helped nor harmed
commensalism
