    October 2014 Cell Division Mitosis Abstract Mitosis and Meiosis: Cells can be divided in unicellular organisms or in multi-cellular organisms. DNA controls the cell division. Bacteria reproduce by a process called binary fission. Bacteria have one chromosome that’s attached to the cell membrane. The chromosome replicates and the two copies separate as the cell grows. Over a period of time this one cell makes two cells. Eukaryotes do the process of mitosis. In mitosis‚ each daughter cell gets about

    Epidermis Cells Aim: To see if rhubarb changes when it is placed in solutions of different concentrations. Introduction: "Plasmolysis in Rhubarb Epidermis Cells" is an experiment to see whether or not rhubarb changed its cell structure when placed within different types or solutions. "A single layer of plant cell is placed on a micrscope slide and either distilled water or 5% NaCl solution is added to the cells. Osmosis will occur resulting in either turgid cells or plasmolysed cells." (www

    Evolution of Eukaryotic Cells from Prokaryotic Cells DNA- Deoxyribonucleic acid (DNA)‚ a self-replicating material present in nearly all living organisms‚ is the acid that carries genetic information. RNA- Ribonucleic acid (RNA)‚ is an acid that is present in all living cells‚ it’s main role is to act as messenger and carry instructions from DNA fro controlling the synthesis of proteins. What are Eukaryotic Cells and Eukaryotic Organisms? A eukaryotic cell is a cell that contains complex

Having the necessary nucleus which holds the cells DNA and produces ribosomes that help in the synthesis of proteins. Surrounding the nucleus is the rough and smooth endoplasmic reticulum. The two help break down and store materials. Rough stores and transports synthesized proteins‚ while smooth stores and transports synthesized lipid‚ steroid hormones

    DEFINITIONS Gametes are mature haploid reproductive cells that unite to form a zygote that develops into a new individual. Gametes are also called sex cells. An egg or ovum is a haploid female reproductive cell or gamete whereas a sperm is a male haploid reproductive cell. A zygote is the initial cell that is formed as a result of the union of a male and a female gamete by means of sexual reproduction. The two haploid cells merge to give rise to a diploid cell which marks the first stage of development.

    Stem cells -are biological cells found in all multi cellularorganisms‚ that can divide (throughmitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In mammals‚ there are two broad types of stem cells: embryonic stem cells‚ which are isolated from the inner cell mass of blastocysts‚ and adult stem cells‚ which are found in various tissues. In adult organisms‚ stem cells and progenitor cells act as a repair system for the body‚ replenishing
