A leaf without a petiole is called a sessile leaf.
Your muscle certainly do. You move, that is you are motile. Plants move very little and are called sessile.
sessile
A starfish is a sessile benthic organism. While they are capable of movement, they primarily inhabit the sea floor and are often found attached to substrates like rocks or coral. They are not pelagic, as they do not live in the open water column.
One example of a sessile land animal is the barnacle. Barnacles are marine arthropods during their larval stage, but once they settle on a surface, they become sessile and attach themselves to rocks, docks, or other substrates. They filter feed using their feathery legs.
Sure, starfish larvae are planktonic. Adult starfish are not.
Yes. Classes of mollusks which include clams, oysters, and other bivalves are sessile filter feeders.
immobile animal/plant
Sessile means nonmotile. Animals in this category include reef-building corals, mollusks, barnacles, and sponges. On land, scale insects mature as sessile animals.
