The organelle is called the mitochondria. It is known as the powerhouse of the cell because it is responsible for generating energy in the form of ATP through the process of cellular respiration.
The organelle responsible for the assembly of proteins is the ribosome. Ribosomes are found in both the cytoplasm and attached to the endoplasmic reticulum, where they read mRNA and synthesize polypeptide chains from amino acids.

mitochondia is greater in number in skeletal muscle cells.
The sarcoplasmic reticulum is a modified form of the endoplasmic reticulum found in muscle cells. It is responsible for storing and releasing calcium ions that are crucial for muscle contractions. The sarcoplasmic reticulum plays a vital role in regulating muscle function.

mitochondrion
The organelle found in animal cells responsible for energy production is called the mitochondrion (plural: mitochondria). Mitochondria generate adenosine triphosphate (ATP), which serves as the primary energy currency of the cell, through processes such as cellular respiration. They are often referred to as the "powerhouses" of the cell due to this critical role in energy metabolism.
This description matches a structure called a myofibril, which is found in muscle cells. Myofibrils are made up of repeating units called sarcomeres that give them a banded appearance. They are responsible for muscle contractions by interacting with motor proteins.
