The red blood cell that is smaller than normal and has less hemoglobin than normal would be called microcytic and hypochromic.

Here's why:

1. "Microcytic" is a term used to describe red blood cells that are smaller than normal. The prefix "micro-" means small, and "-cytic" refers to cells. So, microcytic literally means small cells.

2. "Hypochromic" is a term used to describe red blood cells that have less hemoglobin than normal. The prefix "hypo-" means under or less, and "-chromic" refers to color. Hemoglobin is the protein in red blood cells that carries oxygen and gives the cells their red color. So, hypochromic literally means less color, which in this context refers to less hemoglobin.

Therefore, a red blood cell that is smaller than normal and has less hemoglobin than normal is described as microcytic and hypochromic.
