Functions of the cells The functions of cells are shown in the body which is comprised entirely of cells. Every cell also has its own or more than one job to do. The cell membrane The cell membrane also known as the - plasma membrane. It consist of two layers of a fatty type substance. Its function is to protect the inside and the outside of the cell by allowing certain substances into the cell‚ while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some

My group and I are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads

Chapter-8 Cell: The Unit Of Life What is a cell? Cell is the basic or fundamental structural and functional unit of an organism. What is cell biology? The branch of biology that deals with the study of cell structure and function is called cell biology. DISCOVERIES; Who discovered cell? Robert Hooke observed a live cell in 1665. He observed the cell(actually the cell walls) in the slice of cork under his compound microscope ‚coined the term cell‚ recorded his observations in micrographic

Cell Analogy A Nucleus is like the city hall. The Nucleus directs the activities of all organelles. The City hall controls all activity that occurs in the city. The mitochondria are like the power plants. The mitochondrion converts chemical energy into energy for the cell. The power plants provide energy to all parts of the city. The vacuole is like the land fill. The vacuole stores materials containing water‚ food‚ or waste. The land fill stores harmful waste products safely. The Golgi

Psychological Criticism of “Mending Wall” When authors write a poem they usually have hidden meanings/passage that they are trying to express. With Robert Frost’s “Mending Wall” there is definitely hidden meaning within the 45 lines of the poem. Robert Frost writes this poem in blank verse‚ since it does not follow any rhyming structure. He loosely follows iambic pentameter structure where for the most part the poem has ten syllables; however there are ten lines that have eleven syllables so that

bacteria’s contents intact. The Cell Membrane: Is a phospholipid bilayer that completely surrounds a bacterial cell. Cell membrane acts as a highly selective barrier. This barrier prevents materials from diffusing into and out of the cell. This allows the cell to take up chemicals and nutrients needed for survival while keeping the cell components separated from the environment. The fluid and all its dissolved or suspended particles that can be found within a bacterial cell are called the Cytoplasm.

Mending Wall ~by Robert Frost Something there is that doesn’t love a wall‚ That sends the frozen-ground-swell under it‚ And spills the upper boulders in the sun; And makes gaps even two can pass abreast. The work of hunters is another thing: I have come after them and made repair Where they have left not one stone on a stone‚ But they would have the rabbit out of hiding‚ To please the yelping dogs. The gaps I mean‚ No one has seen them made or heard them made‚ But at spring mending-time

Cell Theory - Biology Speech on Cell Theory. Cells are the "building blocks" of the body. A human is made of millions of cells‚ which are adapted for different functions. They are composed mainly of a cell membrane‚ cytoplasm‚ vacuole(s) and a nucleus. They are the foundations of all living organisms‚ making them probably cells extremely significant when it comes to biology. They are one of the foundations of biology itself. The Cell Theory is a theory that has been composed‚ changed and altered
