anything that causes a reaction or change in an organism or any part of an organism stimulus
the maintenance of a constant internal state in a changing environment homeostasis
reproduction in which the sex cells from two parents unite producing offspring that show traits of both parents sexual reproduction
reproduction that does not involve the union of sex cells and in which one parent produces offspring identical to itself assexual reproduction
the passing of genetic traits from parent to offspring heredity
the sum of all chemical processes that occur in organisms metabolism
an organism that can make its own food by using energy from its surroundings producer
an organism that eats other organisms or organic matter consumer
an organism that gets energy by breaking down the remains of dead organisms or animal wastes and absorbing the nutrients decomposer
a molecule that is made up of amino acids that is needed to build and repair body structure and to regulate processes in the body. protein
a class of energy giving nutrients that include sugars starches and fiber; contains carbon, hydrogen and oxygen carbohydrate
a type of biochemical that does not dissolve in water; fats are lipids lipid
a lipid that contains phosphorous and is a structural component of cell membrane phospholipid
adenosine triphosphate, a molecule that acts as the main energy source for cell processes ATP
in biology, the smallest unit that can perform all life processes, cells are covered by a membrane and have DNA and cytoplasm cell
a phospholipid layer that covers a cell's surface; acts as a barrier between the inside of a cell and its environment cell membrane
one of the small bodies in a cell's cytoplasm that perform specialized functions organelle
in a eukaryote cell, a membrane bound organelle that contains DNA and that has a role in processes such as growth, metabolism and reproduction nucleus
an organism that consists of a single cell that doesn't have a nucleus prokaryote
an organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include plants, animals and fungi but not bacteria eukaryote
a rigid structure that surrounds the cell membrane and provides support to a cell cell wall
cell organelle composed of RNA and protein, site of protein synthesis ribosome
a system of membranes that is found in a cell's cytoplasm and that assists in the production and processing and transport of protein and the production of lipids endoplasmic reticulum
in eukaryotic cells, the cell organelle that is surrounded by two membranes and is the cite of cellular respiration mitrochondrion
cell organelle that helps make and package materials to be transported out of the cell Golgi complex
a small cavity or sack that contains material in an eukaryotic cell vesicle
a cell organelle that contains digestive enzymes lysome
a group of similar cells that perform a common function tissue
a collection of tissue that carry on a specialized function of the body organ
a group of organs that work together to perform body functions organ system
a living thing; anything that can carry out life processes independently organism
the arrangements of parts of an organism structure
the special, normal proper activity of an organ or part function
the movement of particles from regions of higher density to regions of lower density diffusion
the diffusion of water through a semipermeable membrane osmosis
the movement of substances across a cell membrane without the use of energy by the cell passive transport
the movement of substances across a cell membrane with the use of energy by the cell active transport
the process by which a cell membrane surrounds a particle in a vesicle to bring it to the cell endocytosis
the process in which a paricle is released by creating a vessicle that fuses with the cell membrane to release it exocytosis
the process by which plants, algae and some bacteria use sunlight, CO2 and H2O to make food photosynthesis
the process by which cells use oxygen to produce energy from food cellular respiration
the breakdown of food without oxygen fermentation

a kingdom made-up of complex multicellular organisms that lack cell walls, can usually move around and respond to their environment Animalia
the passing of genetic traits from parent to offspring heredity
the trait observed or the first generation when parents that have different traits are bred dominant trait
a trait that reappears in the second generation after disappearing in the first generation when parents with different traits are bred recessive trait
one set of instructions for an inherited trait gene
one of the alternative forms of a gene that governs a characteristic, such as hair color allele
an organism's appearance or other detectable characteristic phenotype
the entire genetic makeup of an organism, also the combination of genes for one or more specific traits genotype
the likelihood that a possible future event will occur in any given instance of the event probability
chromosomes that have the same sequence of genes and the same structure homologous chromosome
a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the cell forming sex cells meiosis
