Cells‚ in a lot of ways‚ are like factories. All the parts of a cell work together to accomplish common goals‚ just like parts of a factory. Each part also has a specific function‚ to make getting the job done a lot easier. The floor of a factory is a lot like the cytoplasm in a cell. It kind of keeps everything where it needs to be‚ and helps direct organelles around the cell‚ much like the pathways on the floor around the machines. The cell membrane in a cell is very similar to the outside

Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

Cells are some of the smallest organisms around. All living things consist of cells‚ and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly. All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support of the cell. A cell membrane

Cell Transformation Cell transformation is when a cell takes in DNA from the outside of the cell. It then becomes a component of the cell’s DNA. There are three different ways in transforming the cells. There is transforming bacteria‚ transforming plant cells‚ and transforming animal cells. The purpose of cell transformation is to introduce a foreign plasmid in order to make large quantities of it. In transforming bacteria‚ a foreign DNA is first joined to a small circular DNA molecule known

THE ORGANELLES OF EUKARYOTIC CELLS . The difference between Prokaryotic and Eukaryotic Cells is organelles‚ membrane enclosed structures that perform specific duties. The most important of all is the “nucleus‚” this holds the DNA and is surrounded by a double membrane. The Prokaryotic lacks a nucleus which is not partitioned from the other cells by membranes. The region between the nucleus and plasma membrane is called cytoplasm and in the Eukaryotic cell it consists of various organelles

The cell functions much in the way a city does. Although it may be an old analogy‚ it may be one of the best. Following is a list of cell parts and how their function is similar to functions of a city or town. The cell membrane is the city limits of our city. Outside of the city limits‚ the local government has no jurisdiction‚ but inside those limits‚ people are subject to the “laws of the land”. The nucleus – This is the place where direction is given and DNA is sent from. This would

(Hint: those buried deep in the cell probably do different things than those closer to the cell membrane). Structure does not affect function of the cells‚ cells have a particular structure that enables them to carry out their function in the best way. 2. Draw a labeled diagram of a small section of the plasma membrane and briefly describe its structure and function. 3. Describe the difference between the animal and plant cells. Plant Cells have cell walls‚ which makes them appear rectangular

Robert Hooke (1665) - observed many kinds of animal tissue under a microscope - concludes that all animals are made up of cells C. Schwann (1868) - observed many kinds of animal tissue - concludes that all animals are made up of cells D.
