Cell Structure & Function
This organelle is often called the "brain" of the cell because it contains the genetic blueprints (DNA).
What is the Nucleus?
This is the primary molecule used by cells to store and release energy for biological work.
What is ATP (Adenosine Triphosphate)?
This double-helix molecule carries the master instructions for building an organism.
What is DNA?
The process by which individuals with favorable traits are more likely to survive and reproduce.
What is Natural Selection?
An organism that must eat other organisms to obtain energy.
What is a Consumer (or Heterotroph)?
Unlike animal cells, plant cells have this rigid outer layer that provides structural support and protection.
What is the Cell Wall?
This process occurs in the chloroplast and converts light energy into chemical energy (glucose).
What is Photosynthesis?
A version of a gene that can be masked by a dominant version, it only shows up if two copies are present.
What is a Recessive Allele?
These are the remains or impressions of prehistoric organisms that provide evidence for evolution.
What are Fossils?
This type of relationship occurs when two different species live closely together and both benefit.
What is Mutualism?
This process describes the movement of molecules from an area of high concentration to an area of low concentration without using energy.
What is Passive Transport (or Diffusion)?
These are the "products" created during cellular respiration in the mitochondria.
What are Carbon Dioxide, Water, and ATP?
This type of cell division results in two genetically identical "daughter" cells, used for growth and repair.
What is Mitosis?
A trait that helps an organism survive and reproduce in its specific environment.
What is an Adaptation?
This term refers to the living parts of an ecosystem, such as plants, animals, and bacteria.
What are Biotic Factors?
These are the small structures within a cell that perform specific functions, much like organs do for the body.
What are Organelles?
This term describes a reaction or process that can occur without the presence of oxygen.
What is Anaerobic?
This square-shaped tool is used to predict the possible genetic outcomes of a cross between two parents.
What is a Punnett Square?
This occurs when a species completely dies out and no members of that species remain on Earth.
What is Extinction?
The study of how organisms interact with each other and their physical environment.
What is Ecology?
This complex organelle is the site of protein synthesis, where amino acids are linked together.
What is a Ribosome?
This green pigment is responsible for absorbing sunlight to power the production of food in plants.
What is Chlorophyll?
This is a permanent change in the DNA sequence that can lead to new traits or genetic disorders.
What is a Mutation?
The scientist famous for studying finches and tortoises on the Galapagos Islands to develop the theory of evolution.
Who is Charles Darwin?
This diagram shows the complex, interlocking pathways of energy flow through many different organisms in an ecosystem.
What is a Food Web?
