Answer:
smooth endoplasmic reticulum
Explanation:
Smooth endoplasmic reticulum differs from the rough endoplasmic reticulum in not having ribosomes on its surface. The smooth endoplasmic reticulum (SER) extends from the rough ER and forms a network of membrane tubules. The function of the smooth ER is to serve as a site for the synthesis of lipids, fatty acids, and steroids such as estrogens and testosterone.
Enzymes for the synthesis of these diverse biomolecules are present in smooth ER. The smooth ER present in the muscle cells is called the sarcoplasmic reticulum. It stores the calcium ions which are released into the sarcoplasm of muscle cells during muscle contraction.

Centrosomes, also called microtubule organizing systems, release the microtubules that arrange the chromosomes along the metaphase plate.
Near the Golgi, there are 9,0 microtubule multiplets that produce microtubules. In order to sustain a dynamic movement process and for the centralized organization of chromosomes along the meiosis,plate, these microtubules bind to the kinetochores of chromosomes utilizing dyneins and kinesins.
During metaphase, chromosomes are organized over the metaphase plate with the help of microtubules released from complexes on various cell surfaces. Microtubules are continuously destroyed and rebuilt in a dynamic process until chromosomes are centrally organized.
