Multicellularity may have evolved because:

Question 4 options:

bulk flow was needed to supply oxygen to interior cells

single-celled organisms are not capable of carrying out all life functions

increased body size allowed organisms to consume single-celled prey

cells needed to develop a way to eliminate waste products

Solution

bulk flow was needed to supply oxygen to interior cells

As the cells grow biger its surface to volume ratio decreases therefore these cells have difficulty in absorbing sufficient nutrients and transporting them throughout the cell. Multicellularity allows an organism to exceed the size limits normally imposed by diffusion.
