Levels of Organization
The smallest unit of life?
What is a cell?
(a) All living things are made of cells. (b) The cell is the basic unit of life. (c) All cells come from preexisting cells.
What is Cell Theory?
Known as the “powerhouse” of the cell; it produces ATP.
What is the mitochondria?
Any inherited feature (behavioral, structural, or physiological) that helps an organism survive and reproduce.
What is an adaptation?
The molecule that stores genetic instructions in living things.
What is DNA?
From smallest to largest: tissue, organism, cell, organ, organ system.
What is levels of organization?
This part of cell theory says every living thing is made of these.
What is cells?
The site of photosynthesis found in plant cells.
What is a chloroplast?
Adaptation type that is a seasonal movement of animals from one region to another to survive changing conditions.
What is what is a behavioral adaptation (migration)?
Different forms of a gene (for example, the gene version for blue eyes vs. brown eyes).
What is an allele? or What is variation?
The level of organization made of different tissues working together to perform a specific function.
What is an organ?
Cell theory states that the cell is the basic unit of both structure and this in living things.
What is function?
These tiny structures read mRNA and assemble amino acids into proteins.
What is a ribosome?
Adaptation type that has coloration or body shape that helps an organism blend into its environment or resemble something else.
What is structural adaptation (camouflage or mimicry)?
A trait that is expressed when at least one dominant allele is present.
What is a dominant trait?
A group of similar cells that work together to perform a specific function.
What is a tissue?
This 17th-century scientist first described “cells” when looking at cork under a microscope.
What is Robert Hooke?
The organelle that controls cellular functions and contains and organism's genetic information.
What is the nucleus?
The process by which populations change over many generations because individuals with certain heritable traits survive and reproduce more successfully.
What is natural selection?
A grid used to predict the probability of offspring inheriting particular traits from parents.
What is a Punnett square?
All the living organisms of the same species that inhabit a specific area.
What is a population?
This statement of cell theory says new cells are produced only by existing cells.
What is “cells come from preexisting cells”
A large organelle in plant cells that stores water, nutrients, and waste and helps maintain turgor pressure.
What is the central vacuole?
Being active at night to avoid daytime heat and conserve water is this type of adaptation.
What is nocturnality?
This term describes the genetic makeup of an organism, which determines which inherited traits it can pass on to its offspring.
What is genotype?
