Rib cage.
The Rib Cage
The calyx, which is made up of sepals, surrounds and protects a maturing bud. Sepals are the outermost part of the flower and provide support and protection to the developing reproductive structures within the bud.
No, the cell membrane is not considered an organelle. It is a structure that surrounds and protects the cell, controlling what enters and exits. Organelles are specialized structures within the cell that perform specific functions.
Cytoplasm
The ovary of a flower develops into the fruit of a plant. After pollination and fertilization, the ovule within the ovary becomes the seed, and the ovary itself matures into the fruit that surrounds and protects the seed.
The cytoplasm includes the fluid and all the organelles within a cell.
The outer layer of the serous membrane that covers each testis is called the tunica vaginalis. It is a two-layered structure that surrounds and protects the testis within the scrotum.
The skeletal structure that surrounds the chest cavity is called the ribcage. It is made up of the ribs, sternum, and thoracic vertebrae, providing protection for the organs within the chest cavity.
These tiny structures are called organelles.
The structures within a cell allow it to specialize by allowing each structure to perform a unique or specific function to its adaptation.
The smallest structure within an animal is a cell. There are, in some cells, many smaller organelles and other structures.
