The organelle involved in the transport of substances within a cell is
Answer: The organelle commonly associated with the transport of substances within a cell is the endoplasmic reticulum (ER). There are two types of endoplasmic reticulum: the rough ER and the smooth ER. The rough ER is studded with ribosomes and is involved in protein synthesis and transport, while the smooth ER is involved in lipid synthesis and detoxification processes. Additionally, the Golgi apparatus also plays a crucial role in modifying, sorting, and packaging proteins for transport to their destination.
1. Endoplasmic Reticulum (ER):
- Rough ER: Helps in synthesizing and transporting proteins. It has ribosomes on its surface, making it appear “rough.”
- Smooth ER: Involved in lipid synthesis and detoxifying chemicals. It lacks ribosomes, giving it a smooth appearance.
2. Golgi Apparatus:
- Modifies proteins and lipids made by the ER and packages them into vesicles for transport to different destinations, such as outside the cell or within other organelles.
Both these organelles work together to ensure the proper distribution of molecules throughout the cell, as well as to provide a pathway for the transport of proteins, lipids, and other substances.
Summary: The endoplasmic reticulum (both rough and smooth) and the Golgi apparatus are key organelles involved in the transport and processing of substances within a cell. The ER mainly synthesizes and transports proteins and lipids, while the Golgi apparatus modifies and packages these substances for further transport.
