Well, it's least complex to most complex. First, there are atoms. The molecules. Then organelles. Then cells. And so on.
New cells technically don't form. Instead, there will be a new cell when a cell splits apart.
When a sperm cell and an egg cell unite they form a zygote which now has the DNA it needs to divide and form a new individual. The sperm cell and the egg cell have one half the amount of DNA necessary to form a new individual.
Only a plant has a cell wall. Animals have cell membranes.
The cell will split and form two new cells. Nice question!

The process by which one cell divides to form two new cells is called cell division. It is an essential process for growth, repair, and maintenance of living organisms.

During cytokinesis in plant cells, the new cell wall that begins to form in the middle is called the cell plate. This structure originates from vesicles that transport cell wall materials to the center of the dividing cell. As these vesicles fuse, they create a partition that eventually matures into a new cell wall, separating the two daughter cells. In contrast, animal cells form a cleavage furrow, which constricts the cell membrane to divide the cytoplasm.
mitosis or meiosis if the cell is a eukaryotic gamete.
