During a class investigation on cells, students observed different cell types using a compound light microscope and prepared slides. An ​ (a)   is a ​ (b)   that has an outermost rigid cell wall and a large vacuole. They appear brick-like in shape. On the other hand, a ​ (c)   is an ​ (d)   having a rounded structure but lacking a cell wall.

What is a major difference between our cells (animal cells) and bacteria cells?

• our cells are less complicated and have less parts

• our cells have a cell wall

• bacteria DNA is hanging out in the cytoplasm

• bacteria don't have a cell membrane
