~an inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment.

~the classification system in which each organism is given a unique, two-part scientific name indicating its genus and species.

~is the scientific study of how organisms are classified.

~the condition in which an organism’s internal environment is kept stable in spite of changes in the external environment.

~a reproductive process that involves two parents that combine their genetic materials from a egg cell and sperm cell.

~a reproductive process that involves only one parent and produces offspring that are genetically identical to the parent.

~is the process of grouping things based on their similarities.

~much smaller than seeds and almost all flowerless plants reproduce by releasing spores into their environment.

~a flowering plant that has one seed leaf (cotyledon), multiples of three petals, and leaves with parallel veins.

~the reproductive structure of a flowering plant; typically contains sepals, petals, stamens, and pistils.

~the male reproductive part of a flower; including the anther and filament.

~a leaflike structure that encloses and protects the bud of a flower.

~the female reproductive part of a flower; including the stigma, style, and ovary.

~a flowering plant that has two seed leaves (cotyledons), multiples of four or five petals, and leaves with branching veins.

~the plant structure that contains a young plant and a food supply inside a protective covering.

~a simple sugar made by plants as their source of food.

~plants absorb energy from the sun and use the energy to convert carbon dioxide and water into sugars and oxygen.

~the sprouting of the embryo out of a seed; occurs when the embryo resumes its growth following dormancy.

~the transfer of pollen from male reproductive structures to female reproductive structures in plants.

~a plant structure in seed producing plants that contain the female’s egg cell.

~tiny structure produced by seed producing plants that contain the cell that later becomes a sperm cell.

~an organelle in the cells of plant and other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food.

~a eukaryotic organism that cannot be classified as an animal, plant, or fungus.

~is a period when an organism's growth or activity stops; helps plants survive freezing temperatures or lack of water.

~a green photosynthetic pigment found in the chloroplasts of plants, algae, and some bacteria.

~small openings on the underside of a leaf through which oxygen, water, and carbon dioxide can move.

~the process in which oxygen and glucose undergo a complex series of chemical reactions inside cell in order to release energy.

~an organism that gets energy by breaking down biotic wastes and dead organisms and returns raw materials to the soil and water.

~cells surrounding the stomata that control when it can open and close.

~the response of a plant toward or away from a stimulus.

~a eukaryotic organism that has cell walls, uses spores to reproduce, and is a heterotroph that feeds by absorbing its food.

~the way a plant moves or grows in response to gravity; roots grow down and stem and leaves grow up (also called geotropism).

~the way a plant moves or grows in response to touch.

~the way a plant moves or grows in response to water; roots grow towards water sources.

~the way a plant moves or grows in response to light; usually grow towards light.
