Platelets (also known as Thrombocytes) circulate in the blood (of mammals) are are involved in hemostasis, leading to the formation of blood clots.
Platelets also keep the body from bleeding in weaker structures including the nose and mouth.
platelets
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.

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.
Red blood cell
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
Thrombocytes, also known as platelets, are formed from the cytoplasm of megakaryocytes in the bone marrow. Megakaryocytes undergo a process called cytoplasmic fragmentation, where they produce small, disc-shaped cell fragments that are released into the bloodstream as thrombocytes.

euglenozoa have disk shaped folds in the mitochondria (cristae)
To optimise the surface area available for the bonding of oxygen and haemoglobin, to form oxyhaemaglobin. Individuals with sickle cell anaemia, i.e. those with red blood cells which are not disk shaped have a reduced capacity to carry oxygen in their blood.
