Different atoms, particularly carbon, hydrogen, nitrogen and oxygen, made up molecules into such things as proteins, lipids, phospholipids, enzymes, and amino acids. These molecules are part of what makes up a cell, including DNA, and is obviously the first "material" that was first seen in cells.
Cells are made/constructed of many different chemicals, but when were they first seen? In the 1670's, Anton van Leeuwenhoek saw microscopic organisms with a microscope that he had fashioned... but there could have been someone who saw them before that... certainly people who knew of their existence.
A. Storing energy
Cells are able to remove large amounts of material through a process called endocytosis, where they engulf particles or molecules by forming vesicles around them. This allows the cell to take in nutrients, regulate signaling molecules, and remove waste products. Cells also use exocytosis to expel material outside of the cell by fusing vesicles with the cell membrane.
This type of cell division is called cytokinesis. It occurs in animal cells, where the cell membrane pinches together in the middle of the cell, forming a cleavage furrow that eventually splits the cell into two daughter cells.
Bone-forming cells are known as osteoblasts. These cells are responsible for the production and mineralization of bone tissue. Osteoblasts play a crucial role in the bone remodeling process, where old bone is resorbed and new bone is formed.
Yes, polar bodies can be seen in a cat's ovary during oogenesis. Polar bodies are small cells that contain genetic material expelled during the process of forming an egg cell. They play a role in reducing the genetic material in the egg to facilitate fertilization.
DNA provides instructions to cells in forming an organ.

Robert Hooke was the first person to see cells. He saw them with a compound-microscope.

Vacuolecantain stored food for cells or wast material form cells.
osteoblasts
The process you are describing is called endocytosis. Endocytosis is a cellular process where cells engulf substances by forming a vesicle or vacuole around the material and bringing it into the cell.
