Cells L1 & L3

What is the role of DNA?

• provides instructions for all cell processes for unicellular & multicellular organisms

• covers the organelles of all cells in order to assist with specialized functions

• improves the ability of one-celled organisms to become two-celled organisms

• alters the life functions of one-celled organisms by limiting their functions

What is a difference between eukaryotic cells and prokaryotic cells?

• Only prokaryotic cells have a cytoplasm.

• Only eukaryotic cells have a cell membrane.

• Only eukaryotic cells have membrane-bound organelles.

Cells of a multicellular organism are specialized. What does this statement mean?

• Cells of a multicellular organism are adapted for performing a specific function.

• Each cell of a multicellular organism can survive independently of the other cells.

• Cells of a multicellular organism are specialized because they have a complex structure.

• Each cell of a multicellular organism can perform all the life functions the organism needs to survive.
