Question

cells are the simplest living units of all organisms. they are known as the \building blocks\ of life. some organisms, like bacteria, are made of just one cell. humans are multicellular organisms, which means they are made of many cells. complex multicellular organisms like humans contain cells that are organized into increasingly complex internal structures: tissues, organs, and organ systems. these structures carry out the functions of life. select the true statements. all living things are made of cells. cells can combine to form complex structures. all organisms contain organs. humans are made of many cells.

Explanation:

• "All living things are made of cells" is a fundamental tenet of cell - theory.
• Cells combine to form tissues, organs, and organ systems which are complex structures.
• Single - celled organisms like bacteria do not have organs, so "All organisms contain organs" is false.
• The text states that humans are multicellular organisms, meaning they are made of many cells.

Answer:

• All living things are made of cells.
• Cells can combine to form complex structures.
• Humans are made of many cells.
