Be Part of Ask A Biologist Nucleus-The nucleus is the control center of the cell. It is the largest organelle in the cell and it contains the DNA of the cell. DNA (Deoxyribonucleic Acid) contains all the information for cells to live, perform their functions and reproduce. Inside the nucleus is another organelle called the nucleolus. The nucleolus is responsible for making ribosomes.

- Most eukaryotic cells contain many mitochondria, which occupy up to 25 percent of the volume of the cytoplasm. These complex organelles, the main sites of ATP production during aerobic metabolism, are among the largest organelles, generally exceeded in size only by the nucleus, vacuoles, and chloroplasts.

Organelle Structure and Function Membrane Bound Organelles. 1  The Nucleus is the largest organelle in a cell. 2  It contains a dense structure called the Nucleolus and is surrounded by the Nuclear Envelope, a structure composed of two membranes, seperated by fluid, which contain a number of nuclear pores that can allow relatively large molecules through. These structures are called Organelles. 2  The fine detail of the cell (which may be revealed by an electron microscope) is called the cell's ultrastructure. 3  Organelles perform different functions within a cell, and this is called the Division of Labour.

- The organelle commonly referred to as the powerhouse of the cell is the mitochondria. This structure is the site for the production of adenosine triphosphate, or ATP, a high-energy molecule that drives various cellular processes essential for the survival of an organism. The process of ATP production is known as respiration.

- In cell biology, an organelle (/ ɔːr ɡ ə ˈ n ɛ l /) is a specialized subunit within a cell that has a specific function. Individual organelles are usually separately enclosed within their own lipid bilayers.

Two Methods to Compute FUTA Tax Liability 1 Multiply the current FUTA tax rate (6.2%) by each employee’s taxable wages up to the wage base ($7,000) paid in the quarter. 2  Add up the results. The total is the gross FUTA tax liability. 3  Next, multiply the maximum allowable credit amount (5.4%) by the same wages up to the wage base.  Add up the results.

11 Cell Organelles and their Functions It is one of the largest organelle in a cell structure. Cytoplasm: This is the fluid matrix of the cell. It encompasses the cell organelles, other solid substances, enzymes, water etc. Its volume is fixed and has a definite pH, tonicity depends on the ionic concentration. Mitochondria: These are sac like organelles inside the cells.

Mitochondrion Mitochondrion, membrane-bound organelle found in the cytoplasm of almost all eukaryotic cells (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP). Mitochondria are typically round to oval in shape and range in size from 0.5 to 10 μm.

- Except for vacuoles, chloroplasts are the largest and most characteristic organelles in the cells of plants and green algae. They can be as long as 10 μm and are typically 0.5 – 2 μm thick, but they vary in size and shape in different cells, especially among the algae.

- The membrane-bound organelle (mini organ) in eukaryotic cells, aka those cells that contain a membrane-bound nucleus, that is the control center of the cell. The nucleus houses the genetic instructions necessary to synthesize proteins and other molecules needed for cell survival, growth, and reproduction.

Organelles in Cells: Definition & Functions Organelles and Their Functions. The nucleus is arguably the most important organelle in the cell. It is the control center, telling all of the other organelles what to do and when to do it. The nucleus also contains all of the cell's genetic material, or its DNA.

Why Is the Egg Larger Than the Sperm? An egg cell, or ovum, is the largest cell in the human body. It contains all of the organelles found in normal cells such as ribosomes, mitochondria, the golgi apparatus, the endoplasmic reticulum and a nucleus. It also contains several structures unique to the ovum such as the corona radiata and the zona pellucida.

What is the Largest Biological Cell? The largest biological cell is often cited as the ostrich egg, which is about 6 inches (15 cm) long and weigh about 3 pounds (1.4 kg).here are at least several biological cells larger than an ostrich egg, despite the fact that even many scientists and laypeople believe the ostrich egg is indeed the biggest. The ostrich may actually be the heaviest cell, but this has not yet been tested.

Learn About Organelles An organelle is a tiny cellular structure that performs specific functions within a cell. Organelles are embedded within the cytoplasm of eukaryotic and prokaryotic cells. In the more complex eukaryotic cells, organelles are often enclosed by their own membrane.
