Organelles exist so the cell can accommodate many different reactions simultaneously through compartmentalization. Some reactions or processes would be harmful to the cell if it were to exist outside of a membrane-bound organelle. For example, lysosomes contain hydrolytic enzymes that are used for digestion when it fuses with a food vacuole. These enzymes couldn't exist freely without cellular damage. Peroxisomes work similarly and can isolate one of its byproducts, hydrogen peroxide, which could be harmful to the cell.
Another main purpose of organelles is increased surface area. In Biology, every reaction depends on speed, and evolution has driven mechanisms that increase surface area. Many organelles are convoluted or twisted to give more space for reaction. The rough endoplasmic reticulum is highly folded with cisternae for ribosomes. The mitochondria has a folded inner membrane that increases the rate of respiration. Through increased surface area and compartmentalization, organelles give rise to complicated eukaryotic organisms.
What else can I help you with?
What is the Cytoplasm's purpose in the cell?
The cytoplasm's purpose in the cell is to hold the organelles together.
Do all the organelles have cell organelles in their cell?
no
Tiny organs of the cell are called?
organelles are the answer
Cell organelles not in a bacterial cell?
all of them, bacteria have no organelles
The purpose of the cytoplasm is to?
The purpose of the cytoplasm is to provide structure and support to the cell, contain organelles, aid in transport of materials within the cell, and facilitate cellular processes like metabolism and protein synthesis.
What are organlles?
Organelles are specialized structures within a cell that perform specific functions. They are like tiny organs within the cell, each serving a different purpose to help the cell function properly. Examples of organelles include the nucleus, mitochondria, and chloroplasts.
How does a cell rid itself of defective of malfunctioning organelles?
Cells can rid themselves of defective or malfunctioning organelles through a process called autophagy. This involves the formation of a double-membrane structure called an autophagosome, which engulfs the damaged organelles and delivers them to lysosomes for degradation. The breakdown products are then recycled for reuse by the cell.
Does a cell membrane have organelles?
No, the organelles are within the cell membrane (in the cytoplasm).
Cell structures that perform specific functions for the cell?
Organelles
What cell organelles resemble?
Many cell organelles resemble sponges.
What is the purpose of the chloroplast in the cell?
Chloroplasts are organelles in photosynthetic organisms such as plants that undergoes photosynthesis, a necessary process in making food.
What is the purpose of the cytoplasm?
The cytoplasm serves as the site for many cellular activities, including metabolism, cellular respiration, and protein synthesis. It also provides structural support to the cell and helps in the movement of organelles within the cell.
