Which of the following types of organisms have cells that are surrounded by a cell wall that provides structure and support?

Fungi, Plants, Bacteria and Archaea

What are the functions of the plant cell wall? Multiple select question.

It maintains cell shape. It helps to determine the direction of cell growth. It provides mechanical support. It prevents osmotic lysis.

What are the functions of the extracellular matrix in animals? Multiple select question.

It provides structural support. It organizes cells and binds body parts together. It provides strength. It participates in cell signaling.

Which of the following best describes an organism that is composed of two or more cells?

Multicellular

How do plants and animals differ in regard to support and organization of cells?

Plant cells are surrounded by cell walls, whereas animal cells secrete an extracellular matrix for support and organization.
