Unicellular vs Multicellular

How do multicellular organisms reproduce?

• Through binary fission involving a single cell.

• Through sexual or asexual reproduction involving multiple cells.

• Through budding from a single parent cell.

• Through fragmentation of individual cells.

Give an example of a multicellular organism.

• Worm

• Bacteria

• Virus

• Yeast

What does 'multicellular' mean?

• A single cell

• Many cells.

• A type of organism that can live in water

• An organism that can only reproduce asexually

How do unicellular organisms reproduce?

• Through a process called binary fission.

• By sexual reproduction involving gametes.

• By budding off from the parent organism.

• Through fragmentation of the organism.

Give an example of a unicellular organism.

• Paramecium

• E. coli

• Streptococcus

• Saccharomyces cerevisiae

What is a multicellular organism?

• An organism made up of multiple cells that work together to carry out life processes.

• An organism that consists of a single cell only.

• An organism that can live without any cells.

• An organism that is made up of cells that do not interact with each other.

What is the role of cells in multicellular organisms?

• Cells are the basic unit of life and can exist independently.

• Cells perform specialized functions and work together to maintain the organism's life.

• Cells are only responsible for reproduction in organisms.

• Cells are primarily involved in the storage of nutrients.

What is an example of a process carried out by unicellular organisms?

• Metabolism, which includes all chemical reactions in the cell.

• Photosynthesis, which occurs in multicellular plants.

• Respiration, which is exclusive to animals.

• Reproduction, which only happens in complex organisms.

What is an example of a process carried out by multicellular organisms?

• Growth, which involves cell division and differentiation.

• Photosynthesis, which occurs in chloroplasts of plant cells.

• Respiration, which is a process of gas exchange in single-celled organisms.

• Reproduction, which is limited to unicellular organisms.

What is the smallest unit of life?

• The cell.

• Tissue.

• Organ.

• Atom.
