When used to describe the growth of cell populations, cell growth refers to the growth and division of the “mother cell” into two “daughter cells”.
A typical eukaryotic cell is comprised of cytoplasm with different organelles, such as nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, and so on. The cellular contents are surrounded by a double layer, cell membrane. These cellular structures and cell junctions are elaborated in this tutorial...
Genes are the blueprint of our bodies, a blueprint that creates a variety of proteins essential to any organism's survival. Find out in this lesson the various factors that affect growth. ..
In plants, growth occurs in meristems, which are the site of repeated cell division of unspecialized cells. These cells differentiate and become specialized in relation to the function they will perform. Learn more about plant meristems in this tutorial...
Plants, like animals, produce hormones to regulate plant activities, including growth. They need these hormones to respond well to their environment and to sustain growth, development, and dispersal. Plant biologists recognize five major groups of plant hormones: auxins, gibberellins, ethylene, cytokinins, and abscisic acid. Find out in this guide the importance of each hormone in the life of a plant...
Genes are expressed through the process of protein synthesis. This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. Also included are topics on DNA replication during interphase of the cell cycle, DNA mutation and repair mechanisms, gene pool, modification, and diseases...
Neurons generate electric signals that they pass along to the other neurons or target tissues. In this tutorial, you will find the basic structure of a neuron, the different classes of neurons, and membrane potentials. It also includes the structure of the nervous system...
