What distinguishes prokaryotic cells from eukaryotic cells?

• Prokaryotes have linear DNA organized into chromosomes, while eukaryotes have circular DNA.

• Prokaryotes have a nucleus, while eukaryotes do not.

• Prokaryotes have circular DNA, while eukaryotes have linear DNA organized into chromosomes.

• Prokaryotes are larger than eukaryotes in size.

What is the cell membrane?

• A protective barrier that regulates what enters and exits the cell.

• A structure that provides energy to the cell.

• A component that stores genetic information.

• A part of the cell responsible for protein synthesis.

How do prokaryotic and eukaryotic cells reproduce?

• Prokaryotic cells reproduce sexually, while eukaryotic cells reproduce asexually.

• Prokaryotic cells reproduce asexually through binary fission, while eukaryotic cells can reproduce asexually (mitosis) or sexually (meiosis).

• Both prokaryotic and eukaryotic cells reproduce asexually through binary fission.

• Eukaryotic cells reproduce only through meiosis, while prokaryotic cells reproduce through mitosis.

What is the function of flagella?

• They are involved in cell division.

• They aid in the movement of some prokaryotic and eukaryotic cells.

• They are responsible for protein synthesis.

• They help in the absorption of nutrients.

What is the difference between unicellular and multicellular organisms?

• Unicellular organisms consist of a single cell, while multicellular organisms are made up of multiple cells that work together.

• Unicellular organisms are larger than multicellular organisms.

• Multicellular organisms can only be found in plants, while unicellular organisms are found in animals.

• Unicellular organisms reproduce sexually, while multicellular organisms reproduce asexually.

What is the role of ribosomes in cells?

• Ribosomes are responsible for energy production in cells.

• Ribosomes are responsible for lipid synthesis in cells.

• Ribosomes are responsible for protein synthesis in both prokaryotic and eukaryotic cells.

• Ribosomes are responsible for DNA replication in cells.

What is the significance of the absence of a nucleus in prokaryotic cells?

• It allows prokaryotic cells to reproduce quickly and adapt rapidly to their environment.

• It enables prokaryotic cells to perform photosynthesis efficiently.

• It provides prokaryotic cells with a rigid structure for protection.

• It allows prokaryotic cells to store genetic material more effectively.

What is cytoplasm?

• A solid structure that provides support to the cell.

• A jelly-like substance within a cell that contains organelles and is the site of many cellular processes.

• A type of organelle responsible for energy production.

• The outer membrane of the cell that regulates what enters and exits.

What are some examples of prokaryotic organisms?

• Bacteria and archaea

• Fungi and plants

• Animals and fungi

• Viruses and protozoa

What is the role of the cell wall in plant cells?

• It provides structural support and protection to plant cells, and is made of cellulose.

• It helps in photosynthesis by capturing sunlight.

• It stores nutrients and waste products for the cell.

• It regulates the movement of substances in and out of the cell.
