- vascular plant tissue that transports water and dissolved minerals away from the roots through the plant.
structure - organisms have the same structures (for example same types of bones) that have different functions (jobs) for the organism.
significant - Something that has given a species an advantage in its environment. For example: Humans standing on 2 legs is evolutionarily significant.

- the sticky, receptive surface at the top of a flower’s female reproductive organ, where pollen grains land and begin the process of fertilization.
- A group of organisms that can interbreed and produce viable offspring (Viable means able to have offspring of their own.)
ancestor - An organism far back in geological history that 2 or more current organisms can be traced back to. For example: all birds can be traced back to small theropods (like a small T-Rex). So a common Ancestor for birds would be theropods.
structure - features in different species that perform similar functions but do not have the same structure (how it's made). These species do not have a common ancestor.
selection - Food and resources are limited so organisms have to COMPETE to get them. Not all offspring will survive only the MOST FIT (not always the strongest!)
system - the body’s largest organ that consists of skin, hair, and nails.
gravitropism - the growth of plants in respect to gravity; roots are positive because they grow down and stems are negative because they grow up against gravity.
mutations - Creates small changes in individuals that may have an effect on the organism's fitness (ability to pass their genes on to another generation) If the mutation causes the individual to be more successful in the environment, it will pass that trait to its offspring, and it will eventually spread through the population over generations.

All the solid parts of the Earth, from the surface to the core. This includes the crust, mantle, and core, as well as features like rocks, soil, mountains, and volcanoes.
An organism, such as bacteria, fungi, and earthworms, that breaks down dead organic matter and waste. This process recycles nutrients back into the ecosystem.
(Adenosine diphosphate)An organic compound essential for the flow of energy in living organisms. When adenosine triphosphate (ATP) releases a phosphate group to provide energy for a cellular process, it becomes ADP.
Pertaining to organisms or processes that require oxygen to live or function. Aerobic respiration, for example, is the process of generating energy in the presence of oxygen.
The green pigment found in the chloroplasts of plants, algae, and some bacteria. It is responsible for absorbing the light energy required for photosynthesis.
Requires oxygen. This process evolved after oxygen became abundant in Earth's atmosphere.
A specialized organelle in plant cells and some algae where photosynthesis occurs. It contains chlorophyll and is enclosed by a double membrane.
A metabolic pathway that breaks down glucose and produces ATP. It consists of three main stages: glycolysis, the Krebs cycle, and the electron transport chain.
Pertaining to organisms or processes that can function without oxygen. Some organisms are facultative anaerobes, meaning they can live with or without oxygen, while obligate anaerobes die in its presence.
An organism that cannot produce its own food and must consume other organisms or organic matter for energy. This category includes animals, fungi, and most bacteria.
