Answer:
The organelle that is probably found in large numbers in muscle cells is the mitochondria (option D).
Step-by-step explanation:
Mitochondria are the organelles responsible for energy synthesis in living organisms. In this organelle, oxidative phosphorylation and electron transport chain occur, culminating in the production of ATP.
Because the muscle cell is always in activity it has a high energy demand, so the mitochondria are the organelles that contain in large number.
the other options are not correct because:
A. Nucleus is responsible for storing genetic information, and all cells contain one.
B. Like the nucleus, all cells possess only one cell membrane.
C. Chromosomes always have the same number in somatic cells.
