Organisms that are permanently attached to a surface, instead of being able to move freely, are called sessile. Plants, mussels and barnacles are examples of sessile organisms.
unelastic
The process by which modern organisms have descended from ancient organisms is called evolution.
Benthos
The bouncing of light off a surface is called reflection. When a light wave is bent it is called refraction.

Many ribosomes are attached to the surface of the rough endoplasmic reticulum. That is why it is called " rough. "

"Fixture" generally refers to things permanently attached to the structure. A light fixture would be one example, screwed to the wall or ceiling. The light fixture, also called a luminaire, would include devices for holding the lighting elements, supplying electricity to them, enclosing the connections for safety, and means for attaching it to the electrical supply permanently. A "fixture" could, in theory, dangle from a cord permanently attached to a suitable support. For contrast, a cord-connected device would not be a fixture. In fact, it is often illegal to use cord and plug on any appliance that is permanently attached (e.g., screwed in or with water pipes attached).
A stationary organism that cannot move to get food is called a sessile organism. These organisms are typically attached to a surface and rely on passive means to obtain nutrients, such as filter feeding or photosynthesis. Examples include corals, sponges, and barnacles.
the answer is phytoplankton or plankton
This joint that you are referring to is called a fixed joint, and cannot be moved or repositioned.
Generally, the organism would be called sessile.
The endoplasmic reticulum (ER) with ribosomes attached to its surface is called rough endoplasmic reticulum (RER). Ribosomes on the RER are responsible for protein synthesis, which is then transported throughout the cell or secreted outside the cell.
