The Cell | One Shot Video | Part 02
Finally wait is over. In my ongoing One Shot Series we already discussed about three parts of cell i.e. cell wall, cell membrane and nuclues. In this video we will discuss the remaining part i.e. cytoplasm in detail. So sit tight and enjoy.
Cytoplasmic organelles are specialized structures found within the cytoplasm of eukaryotic cells. These organelles perform various functions necessary for the cell's survival, growth, and reproduction.
Here's a brief overview of some key cytoplasmic organelles:
Mitochondria: Often referred to as the powerhouse of the cell, mitochondria are responsible for generating adenosine triphosphate (ATP), the cell's main energy source, through aerobic respiration.
Endoplasmic Reticulum (ER): This organelle plays a crucial role in protein and lipid synthesis. Rough ER is studded with ribosomes and involved in protein synthesis, while smooth ER lacks ribosomes and is involved in lipid metabolism and detoxification.
Golgi Apparatus: The Golgi apparatus processes, sorts, and modifies proteins and lipids synthesized in the endoplasmic reticulum. It acts as a distribution and shipping center for these molecules, packaging them into vesicles for transport to their destination within the cell or outside of it.
Lysosomes: Lysosomes are membrane-bound organelles containing enzymes responsible for breaking down waste materials, cellular debris, and foreign invaders such as bacteria through a process called hydrolysis.
Vacuoles: Plant cells typically contain large central vacuoles filled with cell sap, which maintains turgor pressure and stores nutrients, ions, and waste products. In animal cells, vacuoles are smaller and primarily involved in storing and transporting substances.
Peroxisomes: Peroxisomes contain enzymes involved in various metabolic processes, including the breakdown of fatty acids and the detoxification of harmful substances like hydrogen peroxide.
Ribosomes: While not membrane-bound, ribosomes are essential cytoplasmic structures involved in protein synthesis. They can be found either free in the cytoplasm or attached to the endoplasmic reticulum.
Cytoskeleton: While not traditional organelles, the cytoskeleton is a network of protein filaments (such as microtubules, microfilaments, and intermediate filaments) that provide structural support to the cell, help maintain its shape, facilitate intracellular transport, and are involved in cell division and movement.
These organelles work together to ensure the proper functioning and survival of the cell.#mdcat2024 #mdcat2024
