Reactant

substance that exists before a chemical reaction starts.

Recessive

Mendel's name for a specific trait hidden or masked in the F1 generation.

Red Blood Cell

Hemoglobin-containing, disc-shaped, short-lived blood cell that lacks a nucleus and that transports oxygen to all the body's cells.

Red Bone Marrow

type of marrow that produces red and what blood cells and platelets.

Regeneration

ability to replace or regrow body parts missing due to predation or damage.

Reproduction

Production of offspring.

Reservoir

source of a pathogen in the environment.

Response

organism's reaction to a stimulus.

Retina

innermost layer of the eye that contains rods and cones.

Ribosome

Simple cell organelle that helps maufacture proteins.

Rubisco

enzyme that converts inorganic carbon dioxide molecules into organic molecules during the final step of the Calvin cycle.

Scale

small, flat, platelike structure near the surface of the skin of most fishes

Scientific Method

a series of problem-sloving procedures that might include observations, forming a hypothesis, experimenting, gathering and analyzing data, and drawing conclusions.

Sclerenchyma

plant cell that lacks cytoplasm and other living components when mature, leaving thick, rigid cell walls that provide support and function in transport of materials.

Sebaceous Gland

oil-producing gland in the dermis that lubricates skin and hair.

Seed

adaptive reproductive structure of some vascular plants that contains an embryo, nutrients for the embryo, and is covered by a protective coat.

Seed Coat

protective tissue that forms from the hardening of the outside layers of the ovule.

Selective Breeding

directed breeding to produce plants and animals with desired traits.

Selective Permeability

property of the plasma membrane that allows it to control movement of substances into or out of the cell.

Semen

fluid that contains sperm, nourishment, and other fluids of the male reproductive system.

Semicircular Canal

inner-ear structure that transmits information about body position and balance to the brain.

Semiconservative Replication

method of DNA replication in which parental strands seperate, act as templates, and produce molecules of DNA with one parental DNA strand and one new DNA strand.

Seminferous Tubule

tubule of the testis in which sperm develop.

Sepal

flower organ that protects the bud.

Sex Chromosome

X or Y chromosome

Sex Linked Trait

characteristic, such as red-green color blindness, controlled by genes on the X chromosome; also called an X-linked trait.

Sexual Selection

change in the frequency of a trait based on competition of a mate.

Sister Chromatid

structure that contains identical DNA copies and is formed during DNA replication.

Skeletal Muscle

striated muscle that causes movement when contracted and is attached to bones by tendons.

Smooth Muscle

muscle that lines many hallow internal organs, such as the stomach and uterus.

Small Intestine

longest part of the digestive tract; involved in mechanical and chemical digestion.

Solute

substance disloved in solvent.

Solvent

substace in which another substance is dissolved.

Somatic Nervous System

part of the peripheral nervous system that transmits impulses to and from skin and skeletal muscles.

Spawning

process by which male and female fishes release their gametes near each other in the water.

Species

group of organisms that can be interbreed and produce fertile offspring.

Species Diversity

in a biological community, the number and abundance of different species.

Spindle Apparatus

structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides.

Spongy Bone

less dense inner-bone layer with many cavities that contain bone marrow.

Spongy Mesophyll

loosely packed, irregularly shaped cells with spaces around them located below the palisade mesophyll.

Spore

reproductive haploid cell with a hard outer shell that forms a new organism without the fusion of gametes and is produced in the asexual and sexual life cycles of most fungi and some other organisms.

Stamen

male reproductive organ of most flowers composed of filament and an anther.

Stem Cell

unspecialized cell that can develop into a specialized cell under the right conditions.

Stimulant

substance/drug that increases alertness and physical activity.

Stimulus

any change in an organism's internal or external environment that causes the organism to react.

Stroma

fluid-filled space outside the grana in which light-dependant reactions take place.

Substrate

reactant to which an enzyme binds.

Sympathetic Nervous System

branch of the autonomic nervous system that controls organs and is most active during emergencies or stress.

Synapse

gap between one neuron's axon and another neuron's dendrite.

Taste Bud

one of a number of specialized chemical receptors on the tongue that can detect sweet, sour, salty, and bitter tastes.

Telophase

last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided.

Tendon

Tough connective-tissue band that connects muscle to bone.

Thyroxine

thyroid hormone that increases the metabolic rate of cells.

Trachea

Tube that carries air from the larynx to the bronchi.

Thylakoid

in chloroplasts, one of the stacked, flattened, pigment-containing membranes in which light dependant reactions occur.
