Cell growth
The term cell growth is used in two different ways in biology. When used in the context of reproduction of living cells the phrase "cell growth" is shorthand for the idea of "growth in cell numbers by means of cell reproduction.
Mitosis or M Phase: Cell growth and protein production stop at this stage in the cell cycle. All of the cell's energy is focused on the complex and orderly division into two similar daughter cells.

acid) by PLD (phospholipase D)-catalysed hydrolysis of phosphatidylcholine plays a pivotal role in cellular signalling pathways that regulate organization of the actin cytoskeleton, vesicular transport and exocytosis and stimulation of cell growth ...
The cell cycle is an ordered set of events, culminating in cell growth and division into two daughter cells. Non-dividing cells not considered to be in the cell cycle. The stages, pictured to the left, are G1-S-G2-M. The G1 stage stands for "GAP 1".
BRCA1 is believed to act as a tumor suppressor regulating cell growth and division. If suppressor genes are lost or damaged by mutation, uncontrolled cell growth can occur, resulting in cancer.
Cytoplasm - The cytoplasm, or protoplasm, of bacterial cells is where the functions for cell growth, metabolism, and replication are carried out.
Many oncogenes are involved, directly or indirectly, in controlling the rate of cell growth.

The term coined by Johannsen (1909) for the fundamental physical and functional unit of heredity.
Originating in embryology, modern developmental biology studies the genetic control of cell growth, differentiation, and "morphogenesis," which is the process that progressively gives rise to tissues, organs, and anatomy.
During cleavage there is no cell growth between the cell divisions because the egg contains a very large amount of cytoplasm.
Cancer is a disease in which cells escape the restraints on normal cell growth. Cancer is an inheritable disease (at least from cell to daughter cells). Once a cell has become cancerous, all of its descendant cells are cancerous.
Cancer is a group of diseases characterized by uncontrolled cell growth. Cancer begins when a single cell mutates, resulting in a breakdown of the normal regulatory controls that keep cell division in check.
This includes processes for cell growth, reproduction, response to environment, survival mechanisms, sustenance, and maintenance of cell structure and integrity. It is made up of two categories: catabolism and anabolism.
Damaged or mutated DNA may result in uncontrolled cell growth.
Proteins produced by some tumor-suppressor genes stop the cell cycle when DNA becomes damaged.
Abscisic Acid promotes seed dormancy by inhibiting cell growth. It is also involved in opening and closing of stomata as leaves wilt.
Tumor suppressor genes inhibit progression in tumor development. They usually inhibit abnormal cell growth or promote apoptosis. Examples include p53 and Rb.

Proto-oncogene A signal transduction protein that usually regulates cell growth in some fashion; when proto-oncogenes mutated, they become oncogenes and contribute to the development of cancer.
Examples of broad biological process terms are "cell growth and maintenance," or "signal transduction." Examples of more specific terms are "pyrimidine metabolism" or "cAMP biosynthesis. It is not equivalent to a pathway.
