Filtering unit of kidney is nephron. Platelets are present in the muscle part only and not in the initial filtrate .

Through PCT, glucose is reabsorbed in tubular part of nephron.

Each organ of plant exchange gases , leaves exchange gases by stomata , roots through diffusion of gases present in soil and plants with green stems exchange gases through stomata present on their stem but those plants who didn't have green stem or stomata  on their stem exchange gases through lenticels.

In plants gaseous waste products are released throughout stomata. Many products stored in leaves, stems etc. They are stored in form of resins and removed from plants through shedding of leaves or they also released through roots.

Bowman’s capsule is a cup shaped structure that contains tuft of capillaries which help in the filtration of blood.
