Different genes are expressed (see - epigenetics).
Different cells are different in structure because of their different functions (e.g. plant cells have cell walls because they don't have bones). Also, cells have different functions because they work together with other cells to create a working system (e.g. the human body)
Yes. Although their cells are slightly different in terms of structures than us, they are still composed of cells.
Organelles.
Cells are organized according to their function. The function that a cell needs to carry out dictates how it looks, how it functions and what kind of tissue it forms. Plants have very different functions than animals and therefore need different types of cells organized in a different way.
Plants have several things that help to protect it. They have cell walls in their cells, which gives it rigidity and structure. They also have cellulose for strength.

All living things are made up of cells. The structures of different types of cells are related to their functions. Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant and algal cells also have a cell wall, and often have chloroplasts and a permanent vacuole. Bacterial and yeast cells have different structures to animal and plant cells. Dissolved substances pass into and out of cells by diffusion.
cell wall, chloroplasts, and vacuoles
Yes. Although their cells are slightly different in terms of structures than us, they are still composed of cells.
Not all cells demonstrate the presence of all intracellular structures because cells are specialized and have specific functions. Different cells require different intracellular structures to carry out their unique functions. For example, muscle cells have more mitochondria to generate energy for contraction, while red blood cells lack a nucleus to make more space for carrying oxygen.
