Biology- Animal cell The NUCLEUS is the largest organelle in the majority of cells. It contains genetic information in DNA‚ which is responsible for the cells unique characteristics. The nucleus is separated from the rest of the cell by.... ...The NUCLEAR ENVELOPE is used as a barrier which separates the contents of the nucleus from the cytoplasm‚ all in all keeping the DNA safe and intact. The nuclear envelope regulates the flow of substances into and out of the nucleus. The NUCLEOLUS is an important

Cell phones are the way of life today. In the US‚ little kids are carrying around the newest iPhone versions. Closing the digital divide requires studying and learning about the country’s needs and capabilities of upgrading to the digital world. There are countries that are financially unable to afford a cell phone‚ but it should be the cell phone companies that should be able to work around various prices for cell phones. For example‚ in the U.S. the iPhone is taking over and consumers require the

The Xylem is part of a plant‚ which is a hollow tube with spiral thickening of lignin around the wall giving strength‚ which is continuous throughout the whole plant. The difference between the Xylem cell and other cells is that the Xylem is dead and has no cytoplasm. The Xylem is responsible for transporting water and certain nutrients form root to plant. Phloem carries soluble organic material i.e. food for the plant. The top of the plant is in the light‚ conducting photosynthesis and helping the

Cell organelles are specialized cell structures that perform specialized jobs in the cell.* 1. Cytoplasm- *Jelly-like substance inside of the cell 2.

The Cell Theory The Cell Theory‚ formed by Anton van Leeuwenhoek‚ Robert Hooke‚ Matthias Schleiden‚ Theodore Schwann‚ and Rudolf Virchow‚ refers to the idea that cells are the basic unit of structure in every living organism. The theory justifies three principles: all living organisms are composed of one or more cells; the cell is the most basic unit of structure‚ function‚ and organization in all organisms; and all cells come from pre-existing‚ living cells. The formation of the cell theory

Cell City Cell City A cell is like a city. They both have parts that play different roles. A cell is microscopic that has organelles‚ and a city has different services. Keeping them both running smoothly and orderly. As a result they both survive and grow. There’re a lot of different organelles in a cell that are similar to a city for example the cell membrane borders and protects the cell it’s role is letting certain things in and out of the cell in the same way a border in a city does.
