which he called cells’ this in itself unbeknownst to him‚ was the discovery of the fundamental unit of all living things. In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell.’ Over 150 years later this can be regarded as one of the most familiar and important facts within the biological fields.

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan

characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells‚ however‚ cancer cells continue to reproduce. Due to this continued growth a tumor‚ which is a cluster of cancer cells‚ is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells‚ in contrast‚ cancer cells do not respond to these signals. When healthy cells get old or damaged they

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

Around 19 tropical cyclones or storms enter the Philippine Area of Responsibility in a typical year and of these usually 6 to 9 make landfall. The deadliest

Pascal’s law Pascal’s law or the principle of transmission of fluid-pressure is a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same.[1] The law was established by French mathematician Blaise Pascal.[2] Contents [hide] 1 Definition 2 Explanation 3 Applications 4 See also 5 References Definition[edit source | editbeta]
