nucleus and organelles
Chat with our AI personalities
Red blood cells lack a nucleus and organelles, such as mitochondria, which are present in white blood cells. This allows red blood cells to have more space to carry oxygen and carbon dioxide through the bloodstream efficiently.
Leukemia is a type of cancer that results in an overproduction of abnormal white blood cells in the bone marrow. This leads to a decrease in the production of normal blood cells and can cause a lack of healthy white blood cells.
Prokaryotic cells lack a defined nucleus and membrane-bound organelles. They have a single circular chromosome located in the nucleoid region. Prokaryotic cells are generally smaller in size compared to eukaryotic cells.
Animals lack cell walls, which are present in plant cells to provide structure and support. Additionally, animals do not have chloroplasts, which are responsible for photosynthesis in plant cells.
No, an increase in white blood cells COULD do that. (but only if there is a lack of a certain type of WBC)
Yes, leukocytes are also known as white blood cells because they lack color and are responsible for fighting off infections and foreign invaders in the body.
