Cells are a system that creates a product or proteins. To help gain a better understanding of the system of a cell and how it works‚ I will use the analogy “A cell is like an Airport.” The plant cell is the only cell that contains a cell wall. The cell wall’s job is similar to a security gate. The cell wall provides an extra layer of support and protection for the cell‚ just like a security gate would protect the airport. Next‚ the cell membranes job is the same as the airports front doors. The front

‘Discuss how cell organelles are structurally and functionally interrelated’ The Golgi body is a membrane bound organelle mainly found in eukaryotic cells. The Golgi body has two faces the cis face‚ where the substances enter from the RER for processing and the trans face‚ where they exit the RER in the form of tiny vesicles. (Davidson‚ M.

Guadalupe October 29‚ 2012 The effect of temperature on beet cell membranes Introduction: Cell membrane is the plasma like substance that separates different organelles and molecules within an organism. The cell membranes vital function is to permit passage of protein and enzymes through their wall. Red beets‚ also known as Beta Vulgaris has a red pigment that is located in its large central vacuoles. It is my hypothesis that if the cell membrane is to experience extreme temperatures‚ then it’s

Planning AIM Beetroot cells contain a red pigment‚ which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell surrounds it. The outer of the cell is also surrounded by a membrane‚ which again helps contain the pigment inside the cell. In this experiment I aim to find out the relationship between the leakage of red pigment from a beetroot cell and the surface area. To do this successfully I will need to alter the surface area of the beetroot cells accurately and then

what a stem cell is. There is a lack of health literacy in our nation. So the public can’t really get into this dialogue because they don’t understand the complexity of stem cells‚ not the faith based approach‚ not the ideological or political‚ but the science behind stem cells.” Stem cells have the unique ability to transform themselves into whatever type of cells that are needed. They can be the cure for cancer‚ repairing tissue and treating diseases. As we discuss this topic of stem cell research
