Yes. That hard out covering is called an 'exoskeleton', and maintains the spiders' or insects' body shape.
A hard outer covering protects an insect's soft body and gives the insect its shape.
The cell membrane is the outer covering of a cell, protects it and maintains the shape of the cell.
No, insects and roundworms do not have calcium carbonate shells. Insects have exoskeletons made of chitin, a tough, flexible protein. Roundworms lack a hard outer covering and have a smooth, cylindrical body shape.
Wasps, like all insects, are invertebrates. They do not have an internal skeleton, so no vertebra. Their hard outer covering supports and gives shape to their bodies and it is called an exoskeleton.
The outer layer of plant cells is called the cell wall. The cell wall protects the cell from the outside world and gives the cell its shape.
Insects don't have bones. Insects have an exo-skeleton instead, a hard outer layer that protects and gives them shape. The exo-skeleton is made out of Chitin.
Yes. Bees, like all insects, do not have a bony skeleton -- so no vertebrae. They have a hard outer casing called an exoskeleton which gives the body its shape.
No because they are an insect and insects don't have backbones.
In the sense that they do not have a spine, or vertebra: yes. Bees, like all insects, are invertebrate. Their body shape is formed by their hard outer casing.
cortex is generally outer covering of internal organs in body and helps in protecting organs and give them shape. It also helps and guide the movement of substances
Pellicle is outer flexible covering of protozoa and other protists .
