Cell theory and microscopes

1. In the 1600s, advances in microscopes led to the development of cell theory. Which of the following statements is part of the cell theory?

   

   

• All cells require water and oxygen to survive.

• All living things are made of one or more cells.

•  All cells have organelles with specialized functions

• All living things rely on several different types of cells.

In the 1830s, Theodor Schwann showed that the mature tissues of animals were traceable to embryonic cells. Which of the following statements of cell theory does this provide evidence for?

 

•    All living things are made from cells.

•   Cells are the basic units of structure and function in an organism.

•    All cells come from preexisting cells.

•   Each cell has a specific design and purpose.

According to cell theory, which of the following best describes the role of cells in living organisms?

    

• Cells join together to form multicellular organisms.

•    Cells are the basic operating units of living organisms.

• Cells make up the soft portions of tissues in living organisms.

•    Cells are responsible for coordinating activities in multicellular organisms.

Which of the following best describes a way in which all living organisms are similar?

    

    

• They all need oxygen to survive.

•    

     They are all made of at least one cell.

• They are all adapted to survive in their environment.

• They all need energy from other organisms to survive.
