Question

What is organelle?What are it's functions?

Answer 1

Organelles and Their Functions. Thenucleus is arguably the most important organelle in the cell. It is thecontrol center, telling all of the otherorganelles what to do and when to do it. The nucleus also contains all of thecell's genetic material, or its DNA. ...The nucleus is surrounded by two membranes.

Answer 2

HERE IS YOUR ANSWER.....

Every cell in your body contains organelles (structures that have specific functions). Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus , mitochondria and chloroplasts are all organelles.

FUNCTIONS:-

• Ribosomes - Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum. Using the templates and instructions provided by two different types of RNA, ribosomes synthesize a variety of proteins that are essential to the survival of the cell.
• The endoplasmic reticulum - The endoplasmic reticulum (ER) is a membranous organelle that shares part of its membrane with that of the nucleus. Some portions of the ER, known as the rough ER, are studded with ribosomes and are involved with protein manufacture. The rest of the organelle is referred to as the smooth ER and serves to produce vital lipids (fats).
• Nucleus - Known as the cell’s “command center,” the

• as the cell’s “command center,” thenucleus is a large organelle that stores the cell’sDNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA’s orders to the rest of the cell and serves as a template for protein synthesis.
• Mitochondria - The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate). ATP fuels cellular processes by breaking its high-energy chemical bonds. Mitochondria are most plentiful in cells that require significant amounts of energy to function, such as liver and muscle cells.
• Chloroplasts - In plants and some algae, organelles known as
• plants and some algae, organelles known aschloroplasts serve as the site of photosynthesis. Chloroplasts contain a pigment known as chlorophyll, which captures the sun’s energy to transform water and carbon dioxide into glucose for food. Chloroplasts allow autotrophic organisms to meet their energy needs without consuming other organisms.
• Golgi bodies - If the proteins from the rough ER require further modification, they are transported to the Golgi apparatus (or Golgi complex). Like the ER, the Golgi apparatus is composed of folded membranes. It searches the protein’s amino acid sequences for specialized “codes” and modifies them accordingly. These processed proteins are then stored in the Golgi or packed in vesicles to be shipped elsewhere in the cell.
• There are other organelles also which are present in the cell.
