Cell
the basic unit of structure and function in living organisms.
Cell Cycle
the life cycle of cells
Cell Membrane
thin tissue that forms the outer surface of the cytoplasm of a cell that regulates what goes into and out of the cell.
Cell Theory
all organisms are composed of one or more cells; cell is the fundamental structural and functional unit of living matter
Cell Wall
provide protection and gives structure to plant cells by surrounding them.
Cellular Respiration
the process of using oxygen to break down nutrients to release energy for the cell.
Chloroplast
site of photosynthesis in plant cells, the green organelle in plant cells that converts light energy to chemical energy.
Chromosome
in a eukaryotic cell, one of the structures in the nucleolus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA.
Cytokinesis
the division of the cytoplasm of a cell.
Cytoplasm
jelly like fluid that makes up much of a cell inside the cell membrane and, in eukaryotic cells, surrounds the nucleus.
Cytoskeleton
the cytoplasmic network of protein filaments that plays an essential role in cell movement, shape, and division.
DNA
deoxyribonucleic acid, a molecule that is present in all living cell and that contains the information that determines the traits that a living thing inherits and needs to live.
Endoplasmic Reticulum
a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins in the production of lipids.
Function
the special, normal, or proper activity of an organ or part.
Golgi Complex
a cell organelle that helps make and package materials to be transported out of a cell.
Homologous Chromosome
chromosome that have the same sequence of genes and the same structure.
Interphase
the period of the cycle during which activities such as cell growth and protein synthesis occur without visible signs of cell division.
Meisos
a process in cell division during which the numbers of chromosomes decrease half the original number by two divisions of the nucleus, which results in the production of sex cells.
Mitochondria
a organelle in the cytoplasm of eukaryotic cells that converts energy from food into energy a cell can use, the power factor of the cell.
Mitosis
in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosome.
Nucleus
organelle found in the eukaryotic cell that contains genetic material responsible for controlling the activities of the cell.
Organ
a large mass of similar tissue that make up a part of an organism that performs a specific function.
Organelle
differentiated structure within a cell that performs a specific function.
Organism
an individual form of life that is capable of growing, taking in nutrients, and usually reproducing ( organ system working together)
Organ System
composed of several organs working together to perform a specific function.
Vacuole
the organelle that stores water and food in both plant an animal cells.
Lysosomes
the organelle that holds waste materials from the cell and breaks down food, worn out pieces of the cell, and other waste.
Photosynthesis
a chemical reaction during which plants convert radiant energy to chemical energy; converting carbon dioxide and water to sugar.
Ribosome
a cell organelle composed of RNA and protein; the site of protein synthesis.
Structure
the arrangement of parts in an organism.
Tissue
a large mass of similar cells that make up a part of an organism and perform a specific function.
