Smooth ER
The organelle that stores calcium in resting muscle cells is the sarcoplasmic reticulum. Calcium ions are released from the sarcoplasmic reticulum during muscle contraction to trigger muscle activity.

Prokaryotes cells
The immediate source of calcium ion for muscle fiber is the sarcoplasmic reticulum, a specialized organelle within muscle cells that stores and releases calcium ions in response to nerve signals. When a muscle cell is stimulated, calcium ions are rapidly released from the sarcoplasmic reticulum into the cytoplasm, triggering muscle contraction.
The endoplasmic reticulum (smooth ER) is the organelle that makes steroids in gland cells, regulates calcium in muscle cells, and breaks down toxins in liver cells. It is involved in lipid synthesis, calcium storage, and detoxification processes in various cell types.
=it synthesizes complex molecules called steroids in some cells, stores calcium ions in muscles and breaks down toxins in liver=
the vacuole
Endoplasmic reticulum is the organelle that is responsible for synthesizing steroids in gland cells, regulating calcium in muscle cells, and detoxifying substances in liver cells. It consists of rough ER, involved in protein synthesis, and smooth ER, which aids in lipid metabolism and detoxification.
A calciosome is a sarcoplasmic reticulum-like organelle which is involved in intracellar calcium-handling by non-muscle cells.
Vacuoles are organelles that can store food in plant cells. In animal cells, food molecules are stored in small vesicles called lysosomes or in the cytoplasm.
The endoplasmic reticulum is the organelle that stores calcium and is considered the cell's membrane factory. It plays a crucial role in protein and lipid synthesis as well as detoxification processes in the cell.
