Cell Biology
This organelle is known as the "powerhouse" of the cell.
Mitochondrion/Mitochondria
This molecule carries the genetic instructions for all living things.
DNA (Deoxyribonucleic Acid)
This is the largest organ of the human body.
Skin
He authored "On the Origin of Species" in 1859.
Charles Darwin
This term describes a biological community and its physical environment.
Ecosystem
These single-celled organisms lack a nucleus and membrane-bound organelles.
Prokaryotes/Bacteria
This green pigment is essential for absorbing light in plants.
Chlorophyll
These are the building blocks (monomers) of proteins.
Amino Acids
These structures in plant cells are the site of photosynthesis.
Chloroplasts
He is considered the "Father of Modern Genetics" for his work with pea plants.
Gregor Mendel
These tiny air sacs in the lungs are where gas exchange occurs.
Alveoli
This mechanism describes how traits that improve survival become more common.
Natural Selection
These organisms are at the bottom of the food chain, making their own food.
Producers/Autotrophs
This type of medication is used to kill or inhibit the growth of bacteria.
Antibiotics
This tissue in vascular plants transports water from the roots to the leaves.
Xylem
This type of bond involves the sharing of electron pairs between atoms.
Covalent bond
This jelly-like substance fills the space between the cell membrane and the nucleus.
Cytoplasm
This term describes having two different alleles for a particular trait.
Heterozygous
This type of blood vessel carries blood away from the heart.
Artery
These structures are similar in different species because of shared ancestry.
Homologous Structures
This is the maximum population size an environment can sustain.
Carrying capacity
These "non-living" entities require a host cell to replicate.
Viruses
This is the male reproductive part of a flower.
Stamen
These biological catalysts speed up chemical reactions in the body.
Enzymes
This type of transport requires energy to move molecules against a gradient.
This process results in four daughter cells with half the original chromosomes.
Meiosis
This part of the brain is responsible for balance and coordination.
Cerebellum
This term refers to the total collection of genes in a population at one time.
Gene pool
This type of relationship benefits one species while the other is unaffected.
Commensalism
This process involves heating liquids to kill harmful microorganisms.
Pasteurization
This process is the loss of water vapor through the stomata of leaves.
Transpiration
This polysaccharide is the primary storage form of energy in plants.
Starch
These protein-making "factories" can be found free-floating or attached to the Endoplasmic Reticulum.
Ribosomes
This rule states that DNA bases A pairs with T, and C pairs with G.
Chargaff's Rule
This hormone, produced in the pancreas, regulates blood sugar levels.
This type of evolution occurs when unrelated species develop similar traits.
Convergent evolution
This process describes the gradual change in species composition over time.
Ecological succession
These are the three main shapes of bacteria: Cocci, Spirilla, and this one.
Bacilli
These plants produce seeds that are "naked" rather than enclosed in fruit.
Gymnosperms
This molecule, known as the "energy currency," powers most cellular work.
ATP (Adenosine Triphosphate)
