The nucleus is a large membrane bound organelle. Most cells have a single nucleus though skeletal muscle can have more than one (multinucleate) or some cells such as red blood cells have no nucleus. The nucleus contains the genetic material and is where DNA replication and RNA transcription occur. The nucleus is bound by a membrane which contains nuclear pores. These pores allow RNA molecules and proteins to move in and out of the nucleus. However‚ this process is selective and is energy dependent

Prokaryote Organelles: Nucleoid Region: The region in a prokaryotic cell consisting of a concentrated mass of DNA. (The “nucleus” of a prokaryotic cell) The nucleoid instructs all the organelles on what to do. Ribosome: A cell organelle consisting of RNA and protein organized into two subunits and functioning as the site of protein synthesis in the cytoplasm. The ribosomal subunits are constructed in the nucleolus. (Make proteins from amino acids) The nucleoid controls the ribsomes and specifies

Learning about Cells. First thing I want to show you is two beautiful pictures of a Cell. Imagine all of this is in something so small we cannot see it with our naked eyes. About 10‚000 average-sized human cells can fit on the head of a pin. There are a few exceptions‚ but the average cell is very tiny. Here are a few beautiful examples of a cell structure to kind of give you an idea of its beauty‚ and how they fit together. Plasma Membrane (cell membrane) First we are going to learn about

P1 [pic] Cell membrane - encloses the contents of the cell and regulates the flow of substances into and out of the cell. Mitochondrion - this feature produces a substance called adenosine triphosphate (ATP) which is the carrier of energy in all cells. Centriole - these two features made of hollow tubules play a key role in cell division. Ribosomes - these small‚ granular features of the cell play a key role in the assembly of proteins. Chromosome - During cell division‚ DNA‚ the

Part of speech From Wikipedia‚ the free encyclopedia In grammar‚ a part of speech (also a word class‚ a lexical class‚ or a lexical category) is a linguistic category of words (or more precisely lexical items)‚ which is generally defined by the syntactic or morphological behaveour of the lexical item in question. Common linguistic categories include noun and verb‚ among others. There are open word classes‚ which constantly acquire new members‚ and closed word classes‚ which acquire new members

purpose of the investigation is to determine the time an onion cell spends in each part of the cell cycle. B. The significance of this investigation is to help us understand and know how long cells are undergoing mitosis. My personal interest is to know the phases of mitosis in cells in order to someday help find cures for cancer. C. The cell cycle is a chronological set of events‚ culminating in cell growth and division into two daughter cells. Some of the reasons why mitosis occurs include growth‚ tissue

Page 1 of 8 BIOLOGY 12- CELL STRUCTURE & FUNCTION Chapter Notes THE CELL THEORY • Although different living things may be as unlike as a violet and an octopus‚ they are all built in essentially the same way. The most basic similarity is that all living things are composed of one or more cells. This is known as the Cell Theory. • our knowledge of cells is built on work done with microscopes • English scientist Robert Hooke in 1665 first described cells from his observations of cork slices
