No, all cells are not alike in structure and metabolic activities. Cells can vary in size, shape, and specialized functions depending on their location and role in the body. Different types of cells have specific metabolic activities and structures tailored to their functions.
that's a bit tricky question. E.g. in B-lymphocytes, Endoplasmic reticulum with Golgi would that be. In theory, you could say that cytoplasm is the largest "structure". Usually, you would answer that the largest cellular structure is plasmatic membrane, but this is not intracellular. So I conclude that in many cells, cytoskeleton is the largest intracellular structure. Cytoskeleton is quite wide in many cells. By the way, in plants it is easier - usually, vacuole is definitely the largest structure in many plant cell types.
Water is a universal solvent that dissolves many substances, and it also fills up cells to maintain their structure and function.
Yes, but not just animal cells, all cells. Chromosomes are complexes of a DNA molecule with many proteins that provide structure and influence gene regulation. All cells have chromosomes.
One key feature of viruses that is not found in cells is the lack of a cellular structure or organelles. Viruses are composed of genetic material (DNA or RNA) surrounded by a protein coat, whereas cells have a complex structure with membrane-bound organelles.

all have the same structure

A cells with many nuclei is often called a syncytium. The normal cell structure for many types of fungi is a syncytium.
pituitary
The cell has many branches that enable it to communicate with other cells in the brain easily.
Yes, grass is made of cells. Each blade of grass is composed of many individual cells that make up its structure and function.
The smallest structure within an animal is a cell. There are, in some cells, many smaller organelles and other structures.

A structure made of many similar cells to perform a simple function. That function depends on what kind of cells they are made of.

A mushroom is composed of many cells, primarily in its fruiting body structure. The number of cells in a mushroom can vary depending on its size and species, but it can range from thousands to millions of cells.
