Organisms Quiz

What is the main difference between unicellular and multicellular organisms?

• Unicellular organisms are larger in size

• Unicellular organisms have a longer lifespan

• Multicellular organisms have a low level of efficiency

• Multicellular organisms consist of multiple cells

How do unicellular organisms carry out all life processes?

• Through phagocytosis

• By using internal structures called organelles

• By forming tissues and organs

• By engulfing food in food vacuums

What is the method by which a single cell of a unicellular organism manages nutrition?

• By engulfing food in food vacuums

• Through phagocytosis

• By forming tissues and organs

• By using internal structures called organelles

Why can multicellular organisms grow larger in size compared to unicellular organisms?

• Due to a higher level of efficiency

• Because they have a longer lifespan

• By having a low surface area to volume ratio

• By increasing the number of small cells

What happens when there is an injury to the cell of a unicellular organism?

• The organism can carry out all life processes

• The organism can grow larger in size

• The organism can replace the injured cell

• The organism may die

Which type of organisms are prokaryotes?

• Unicellular

• Multicellular

• None of the above

• Both unicellular and multicellular

What is the main advantage of multicellular organisms over unicellular organisms?

• Higher efficiency

• Longer lifespan

• Ability to carry out all life processes

• Increased surface area to volume ratio

How do specialized organs in multicellular organisms carry out life processes?

• By engulfing food in food vacuums

• Through phagocytosis

• By using internal structures called organelles

• By working together in systems
