The Stem Cell Research

Stem cell research involves the technology that uses generic cells that can duplicate themselves indefinitely and has the ability to create particular needed cells and tissues such as blood, brain cells, muscle and liver tissue. This research began in the mid-1800s, when it was discovered that particular cells could produce other cells and by the […]

The Cell Membrane

Cell membrane is the focus of this laboratory experiment. The plasma membrane has got three components namely cholesterol, protein, and phospholipid (glycerol and charged phosphate). The molecules of phospholipid have got one water soluble end (hydrophilic) and the other end which is not soluble in water (hydrophobic). The hydrophilic head is composed of glycerol, negatively […]

The Cell Cycle

1) Briefly describe all phases of the cell cycle and tell what happens in each. a) Interphase: G1 phase, S phase, G2 phase G1- the size of the cells increases, synthesize proteins and produce RNA. The DNA synthesis is also enhanced. S phase- the replication of DNA takes place which produces the two similar daughter […]

Importance of Studying the Cell and its Components

The bodies of all animals and plants are made up of tiny microscopic units called cells. These make up the structure of the organism and are responsible for carrying out the various processes characteristic of the organism. Some organisms are composed of only one cell and are referred to as unicellular and include Amoeba, Paramecium […]

The effect of stress on beet cell membrane

All cells have three things they share, a plasma membrane, DNA, and cytoplasm. Phospholipids are the main materials of all cell membranes found usually in the lining of the cell’s plasma membrane. This is something of a border patrol of what’s allowed in the cell and what goes out of the cell. On a scale […]

Unicellular

A unicellular organism is any life form that consists of just a single cell. Most of life is unicellular, with bacteria serving as the majority. The main groups of unicellular life are bacteria, archaea (both prokaryotes), and the eukaryota (eukaryotes). The differences between the prokaryota and eukaryota are significant: eukaryotes possess a nucleus, while prokaryotes […]

How the Cell Cycle Operates

A cell is a dynamic system. It is “born,” lives, grows, reproduces, and dies. Each cell works like an automated factory, duplicating parts of it. It interacts with its environment, sending and receiving signals—electrical and chemical—to act on or cause action elsewhere, and guarding against invaders or aggressively attacking other cells. A cell changes shape, […]
