platelets
No, platelets do not contain mitochondria. Platelets are small, disc-shaped cell fragments that lack a nucleus and other organelles, including mitochondria. They primarily function in blood clotting.
Platelets are small, disc-shaped cell fragments with no nuclei. They are the smallest type of blood cell and play a key role in blood clotting by forming clots to stop bleeding. Platelets are typically 2-4 micrometers in diameter.
Platelets are small, disc-shaped cells that aid in blood clotting. Their shape allows them to adhere to damaged blood vessel walls and come together to form a plug at the site of injury, helping to stop bleeding. The disc shape also helps platelets flow easily through blood vessels and interact with other blood cells.
Platelets are not cells, they are fragments of cells that were created when larger cells in the bone marrow broke apart. Platelets play an important role in blood clotting.

Blood cells are typically disc-shaped with a concave center, resembling a biconcave disc. Red blood cells have this shape to increase their surface area for oxygen and carbon dioxide exchange. White blood cells are larger and varied in shape, allowing them to engulf foreign particles and pathogens.
Sickle-cell anemia.
The optic disc is crucial to the eyes. It functions as an entry point for the vessels which supply blood to the retina.
red blood cells are disc shaped while white blood cells have no permanent shape.
Spherical bi-concave disc. This shape is due to the absence of a nucleus.a red blood cell is like a disc with a dent in the middle.it is known to be a cell without a nucleus.however,young red blood cells do have a nucleus,just as the grow older,they loose it.blood contains hemoglobin which contains iron which gives blood its metalish smell.however in rare cases,the red blood cell is shaped like a sickle due to chromosomes,resulting in what we call sickle cell anemiaBiconcave Disc Shapeit is kinda shaped like a doughnut but the center isn't totally goneThe shape of RBC (Red Blood Cells) are Biconcave disc-shaped cellsYou can see pictures by following the related links below.Read more: What_is_the_shape_of_a_red_blood_cell
The sievelike disc-shaped opening in an echinoderm's body through which water enters and leaves is called the madreporite. It is the entrance to the water vascular system, which helps in functions like respiration and movement.
