Cell Divison Flashcards
What is the primary method unicellular organisms use to increase their population?
Cell division
Unicellular organisms, like bacteria, cannot grow in size indefinitely.
How do multicellular organisms grow larger than unicellular organisms?
They use cell division to form complex organ systems
This allows for greater size and specialization.
What happens to cells after they have divided in multicellular organisms?
They usually enlarge and become specialised.
What are undifferentiated cells called?
Stem cells.
Where can stem cells be found in humans?
Developing embryos and some adult tissues (e.g., bone marrow, blood, liver).
What types of diseases are researchers investigating stem cells to treat?
Diabetes, Parkinson’s disease, and heart disease.
True or False: All living things grow in the same way.
False.
Fill in the blank: Unicellular organisms, like bacteria, grow by _______.
cell division.
What is the difference between unicellular and multicellular growth?
Unicellular organisms increase numbers, multicellular organisms form complex organ systems.
