principle‚ a purple onion cell is going to be bathed in different concentrations of salt (NaCl) water. Problem: How do solutions of various salt concentrations influence osmosis in relation to an onion cell? Hypothesis What will happen to the onion cell if it is placed in salt water? What will happen to the onion cell if it is placed in distilled water? If ..the onion cell is placed in salt water then... the cell will shrivel up The

Cell membrane: The cell membrane surrounds the cytoplasm of a cell and its job is to protect the inside of a cell by only allowing certain substances into the cell and keeping other substances out. It also helps to support the cell and maintains its shape. Nucleus: This is the biggest part of the cell and is the part of the cell which acts like the brain. It is not always in the middle of the cell but will be placed within the cytoplasm. In some cases a cell may have many nuclei and these are

How is the structure of cells related to their function? Cell structures come in various shapes and sizes dependent on their location within an organism and what life sustaining process it carries out. These can range from the globular protein of a red blood cell‚ designed to carry four oxygen molecules at a time to the tail like flagellum of a bacteria designed for mobility and penetration of organs within a body. There are two main types of cells‚ eukaryotic cells which are generally plant

SCIENCE CELL – STRUCTURE AND FUNCTIONS Cell – Structure and Functions Cell as the Basic Unit of Life The cell is the basic structural and functional unit of all living organisms. It is the smallest part of the body of an organism‚ is capable of independent existence and is able to perform the essential functions of life. Discovery of the Cell Robert Hooke observed cork cells under a simple microscope designed by him. He observed compartments resembling honeycombs and each compartment

Snow white and Red rose There was once a poor woman who lived in an old thatched cottage .In front of the cottage grew two rose bushes. One grew flowers as white as snow‚ the other had flowers as red as wine. The woman had two daughters who resembled these rose bushes: one had a complexion as white as snow‚ the other lips as red roses. She named her daughters snow white and red rose. They were both good girls‚ but very different. Snow white‚ the elder‚ liked to stay with her mother and help her

within and around all cells’ The plasma membrane surrounds all eukaryotic and prokaryotic cells. Eukaryotic cells have membrane bounded organelles whereas prokaryotic cells do not. The plasma membrane forms the boundary between the cell cytoplasm and the environment. Its function are to allow different environments to be established inside and outside the cell. It also controls the movement of substances into and out of the cell. The cell surface membrane which surrounds all cells consists of many components

by Francisco Pizarro on January 18‚ 1535. The Peruvian flag is a vertical triband. It is red on the left and right‚ and white in the middle. It has an escudo partitioned into 3 unequal parts (the bottom being larger). The current flag was officially adopted on February 25‚ 1825. In this paper I will be talking about 3 properties of the flag. What the Cinchona tree represents on the flag‚ what the red and white represent on the flag‚ and what the golden cornucopia represents on the flag. The Cinchona
