Organelles definition, a specialized part of a cell having some specific function; a cell organ. See more.
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function.Organelles are either separately enclosed within their own lipid bilayers (also called membrane-bound organelles) or are spatially distinct functional units without a surrounding lipid bilayer (non-membrane bound organelles). Although most organelles are functional units within cells.
Essay Questions On Cell Biology 1. Describe each cell organelle and its function. What is the difference between the nuclear envelop and the cell membrane in terms of structure and function? 2. 3. Which organelle has its own DNA? How does this relate to maternal genetics? Describe the molecular components of ATP. How do ADP and P relate to ATP and energy generation and energy storage? 4. 5.
Cell organelles Cells are incredibly complex and most complex cell would be a eukaryotic cell. It has many different organelles and each hold a specific job. Nucleus is very large and is controlling the whole system of the cell. The nucleus contains DNA in the form of chromosomes and is the site of synthesis of RNA. It is separated from the rest of the cell by a double membrane (envelop.

Living things are made of cells, or biological units also referred to as the building blocks of life. Some organisms consist of just one cell, while others are made of trillions of cells. Each one of these.
A typical cell may contain 1,000 mitochondria, though some will contain many more. Generally, they are sausage-shaped organelles whose walls consist of 2 membranes. The inner membrane is folded inwards to form projections called cristae.Inside this is the matrix. Most of the reactions for aerobic respiration take place in the mitochondria so it is an incredibly important organelle.

The word “organelle” means “little organ,” and, as already mentioned, organelles have specialized cellular functions, just as the organs of your body have specialized functions. Figure 1. These figures show the major organelles and other cell components of (a) a typical animal cell and (b) a typical eukaryotic plant cell. The plant cell has a cell wall, chloroplasts, plastids, and a.
