Multicellular Organism Cell Functions

The video explores the transition from single-celled to multicellular organisms, highlighting the methods cells use to join together, such as mutation and glue production. It discusses the advantages of multicellularity, like increased energy and protection, and the challenges posed by selfish cells. The video explains how evolution favors groups with similar DNA, leading to specialization and programmed cell death to ensure survival. It concludes with the evolutionary origins of multicellular organisms.

What are the two initial strategies a cell can use to become multicellular?

• Dividing and not fully separating or producing a glue-like substance

• Becoming larger or changing shape

• Absorbing other cells or producing toxins

• Developing a hard shell or moving faster

What is one of the main advantages of being multicellular?

• Ability to fly

• Increased energy from floating to the water's surface

• Resistance to all diseases

• Ability to change color

What problem arises when some cells in a multicellular group do not cooperate?

• They outcompete others by not sharing the costs

• They start glowing

• They become invisible

• They turn into plants

How do cells ensure that all members of a colony have similar DNA?

• By absorbing other cells

• By moving to a different environment

• By dividing and forming a colony with similar DNA

• By changing their color

What is the role of specialized cells in a multicellular organism?

• To form a protective skin and invest energy into becoming tougher

• To produce toxins

• To change the organism's color

• To absorb sunlight

Why do some cells in a multicellular organism not grow as fast as others?

• They are too old

• They are absorbing too much sunlight

• They are forming a protective skin

• They are lazy

What genetic instructions prevent cells from outcompeting each other?

• Instructions to change color

• Instructions to never outcompete others

• Instructions to move faster

• Instructions to absorb more sunlight

What happens to a cell when it becomes less efficient in a multicellular organism?

• It absorbs more sunlight

• It kills itself for the benefit of the group

• It changes color

• It becomes a leader

What is the evolutionary advantage of programmed cell death?

• It helps cells absorb more sunlight

• It makes cells faster

• It ensures the survival of the organism's DNA

• It allows cells to change color

What would happen if a cell decided not to die and tried to reproduce instead?

• It would become a cancer and potentially harm the organism

• It would become invisible

• It would absorb more sunlight

• It would change color
