A genetically determined characteristic

trait

A group of similar cells that perform a common function.

tissue

A plant structure that provides support and transports nutrients.

stem

A specialized structure that contains the ends of sensory neurons and that responds to the specific types of stimuli.

sensory receptor

A plant embryo that is enclosed in a protective coat.

seed

The mainly underground organ of vascular plants that holds plants in place and absorbs and stores water and minerals from the soil.

root

A collection of organs whose primary function is to take in oxygen and expel carbon dioxide; the organs of this system include the lungs, the throat, and the passageways that lead to the lungs.

respiratory system

A molecule that is made up of amino acids and that is needed to build and repair body structures and to regulate processes in the body.

protein

The trasfer of pollen from the male reproductive structures to the female structures of seed plants.

pollination

A new organism that results from sexual or asexual reproduction.

offspring

In a eukaryotic cell, a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction.

nucleus

The structures that control the actions and reactions of the body in response to stimuli from the environment. it is formed by billions of specialized nerve cells called neurons.

nervous system

The organ system whose primary function is movement and flexibility.

muscular system

The ability to store and recall past experience.

memory

A plant organ that is the main site of photosynthesis and transpiration.

leaf

The process by which a characteristic is passed from parent to offspring.

inheritance

The maintenance of a constant internal state in a changing environment.

homeostasis

One set of instructions for an inherited trait.

gene

A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote

gamete

The system that collects and excretes nitrogenous wastes and excess water from the body in the form of urine.

excretory system

The organs that break down food so that it can be used by the body

digestive system

The body system made up of the heart, the blood vessels, and the blood

circulatory system

In a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA

chromosome

An action that an individual carries out in response to a stimulus or to the environment.

behavior

Reproduction that does not involve the union of sex cells and in which one parent produces offspring that are genetically identical to the parent

asexual reproduction

One of the alternative forms of a gene that governs a characteristic, such as hair color

allele

a rigid structure that surrounds the cell membrane and provides support to the cell

cell wall

An organelle found in plant and algae cells where photosynthesis occurs

chloroplast

In eukaryotic cells, the organelle that is the site of cellular respiration, which releases energy for use by the cell

mitochondria

In a eukaryotic cell, a membrane-bound organelle that contains the cell's DNA and has a role in processes such as growth, metabolism, and reproduction

nucleus

An organism that consists of a single cell

unicellular organism

A living thing; anything that can carry out life processes independently

organism

One of the smallest bodies that are found in the cytoplasm of a cell and that are specialized to perform a specific function

organelle

An organism that consists of more than one cell

multicellular organism

A phospholipid layer that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment

cell membrane

In biology, the smallest unit that can perform all life processes.
