HOPEFULLY IT HELPS! PLEASE MARK AS BRAINLIEST!
Answer:
Mitochondrial is an oval shaped semiautonomous organelle as it contains circular DNA.
Lysosomes are called as garbage disposal as it contains a hydrlytic enzyme that digests wastes material, cell debris, foreign particles and dead or weak organelles and excretes out from the cells.
Vacuoles are microscopic droplet like bodies, found scattered in the cytoplasm. In mature cells, they get fused to produce a large vacuole. They are non-living reservoirs and are enveloped by a unit membrane structure. The sap of the vacuole is called as the cell sap.
The endoplasmic reticulum has a central role in lipid and protein biosynthesis. Its membrane is the site of production of all the trans membrane proteins and lipids for most of the cell's organelles, including the ER itself, the Golgi apparatus, lysosomes, secretory vesicles and the plasma membrane. Almost all of the proteins that will be secreted to the cell exterior plus those destined for the lumen of the ER, Golgi apparatus or lysosomes are initially delivered to the ER lumen.
The nucleus is considered to be one of the most important structures of eukaryotic cells as it serves the function of information storage, retrieval and duplication of genetic information. It contains chromosomes which house the DNA. The cell nucleus acts like the brain of the cell. It helps in control of eating, movement, and reproduction of the cell. It works as the cell's control center.
