Cells: The Building Blocks of Life

What is the definition of a multicellular organism?

• The process of increasing in size and complexity
• Living organisms consisting of a single cell
• Living organisms composed of multiple cells that work together
• The ability of living organisms to maintain a stable internal environment

What is the smallest unit that can be said to be alive?

• Cell
• Organ
• Atom
• Molecule

What is the difference between unicellular and multicellular organisms?

• Unicellular organisms are made up of only one cell, while multicellular organisms are made up of trillions of cells
• Unicellular organisms are not made up of cells, while multicellular organisms are made up of cells
• Unicellular organisms and multicellular organisms are made up of the same number of cells
• Unicellular organisms are made up of trillions of cells, while multicellular organisms are made up of only one cell

What is the main component of living things?

• Organs
• Atoms
• Molecules
• Cells

What is the definition of homeostasis?

• The set of processes by which living organisms convert nutrients into energy
• The ability of living organisms to maintain a stable internal environment
• The basic structural and functional units of all living organisms
• The process of adjusting and changing to fit new conditions or environments

What is an organism that consists of one single cell called?

• Unicellular
• Bicellular
• Tricellular
• Multicellular

What is the function of specialized cells in multicellular organisms?

• To perform specific functions that support the life of the organism
• To perform all the functions necessary for the organism's survival
• To divide and create more cells
• To protect the organism from harmful substances

What is an example of a unicellular organism?

• Dog
• Elephant
• Bacteria
• Human

What is cell specialization?

• When cells in unicellular organisms combine
• When cells in multicellular organisms die
• When cells in unicellular organisms divide
• When cells in multicellular organisms develop different functions

What is the role of cells in living things?

• Cells are only important for multicellular organisms
• Cells work together as a system to support the life of the organism
• Cells are not important for living things
• Cells are only important for unicellular organisms
