Not all cells are alike. Which of the following is NOT a true statement about differences between cells?
Some cells have a nucleus, but others do not.
Different kinds of cells are different sizes.
Most cells have a membrane, but some do not.
Cells come in many different shapes.
Which of the following best describes the relationship between the nucleus and the cytoplasm?
The cytoplasm is an organelle that is usually found near the nucleus.
The nucleus is a fluid and it mixes with the fluid cytoplasm.
The nucleus is an organelle that is surrounded by the cytoplasm.

Diffusion occurs because
cellular energy pumps molecules across the cell membrane.
:molecules constantly move and collide with each other.
molecules are attracted to one another.
cellular energy forces molecules to collide with each other.

an organ system
a tissue
a division of labor
an organ
An organ system is a group of organs that
work together to perform a specific function.
are made up of similar tissues.
are made up of similar cells.
work together to perform all the functions in a multicellular organism.
