Final answer:
The type of cells you were working with in the lab today were red blood cells. Red blood cells deliver oxygen to cells and remove carbon dioxide. They are formed from stem cells in the bone marrow.
Step-by-step explanation:
The type of cells you were working with in the lab today were red blood cells (C).
Red blood cells are responsible for delivering oxygen to cells and removing carbon dioxide. They are specialized cells that circulate through the body and are formed from stem cells in the bone marrow. In mammals, red blood cells are small biconcave cells that do not contain a nucleus or mitochondria at maturity.
Examples:
- In humans, red blood cells are approximately 7-8 µm in size, lack nuclei and mitochondria, and contain hemoglobin.
- Birds and non-avian reptiles have red blood cells that still maintain a nucleus.
