Hi I'm Jackie, and I'm here to help you with your Physics problem! :)
Lets first get to understand what these cells are!
Multicellular: (of an organism or part) having or consisting of many cells.
Cytoplasm: the material or protoplasm within a living cell, excluding the nucleus.
Unicellular: (of an evolutionary or developmental stage) characterized by the formation or presence of a single cell or cells.
Nucleus: A dense organelle present in most Eukaryota cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
What does it sound like to you? :)
