Centrosome

Centro some: They are found in most animal cells, but they are rarely found in the cells of some lower plants. The centrifuges in a centro some develop astral ray, thus they play a significant role in constructing spindle apparatus. They also take part in forming different types of flagellum, and are mainly found in animal cells. Cell vacuole: Large vacuole is prime feature of a plant cell. Its main function is to contain cell sap. Different types of substances such as inorganic slat, protein, carbohydrate, fat, organic acid, pigment, water etc. are found in a cell vacuole. No vacuole is generally found in any animal cell. If present in any animal cell, it usually is much smaller. Lysosomes: Lysosomes break down waste materials in a cell. The strong enzymes within them help do this task. Moreover, it protects cells by engulfing unexpectedly invaded microorganisms, viruses and bacteria. The membrane around lysosomes protects the rest of the cell from degradation enzymes within lysosomes. They are found in animal cells. Nucleus: The nucleus is a membrane bound prominent organelle found in the Eukaryota cells. It is roughly round or spherical in structure. Mature sieve cells and red blood cells lack nucleus. A nucleus houses the heredity information in it, and controls all the activities of a cell. A well structured nucleus has the following parts. The membrane that encloses the nucleus is called nuclear membrane, there are some channels called nucleolus. Substances get in and out of a nucleus through the pores. The membrane separates the contents of a nucleus from cytoplasm. Neoplasm: The jell-like fluid enveloped by nuclear membrane is called neoplasm. It is similar to the cytoplasm of a cell.  The viscous fluid contains to the cytoplasm of a cell. The viscous fluid contains nucleic acids, proteins, enzymes and some other substances dissolved in and mixed with it.
