Hey there! What's the special role of plasmids in prokaryotic cells?

• Plasmids help in cell division in prokaryotic cells.

• Plasmids act as storage for genetic material in prokaryotic cells.

• Plasmids contribute to providing selective advantages, such as antibiotic resistance.

• Plasmids are responsible for energy production in prokaryotic cells.

What is the main role of ribosomes in prokaryotic cells?

• DNA replication

• Energy production

• Cell division

• Protein synthesis

What is the genetic material in prokaryotic cells called?

• Carbohydrate

• DNA

• Protein

• RNA

What are the different shapes of prokaryotic cells?

• Rod-shaped, spherical, spiral, and pleomorphic

• Square, oval, hexagonal, and irregular

How do prokaryotic cells obtain energy?

• By absorbing nutrients from the environment

• Through processes such as glycolysis, fermentation, and cellular respiration

• Through photosynthesis

• By converting sunlight into energy

What is the role of the nucleoid in prokaryotic cells?

• Regulates the cell's temperature and pH levels

• Produces energy for the cell through photosynthesis

• Stores excess water and nutrients for the cell

• Controls the cell's activities and contains genetic material (DNA)

How do prokaryotic cells regulate their internal environment?

• Passive transport and endocytosis

• Passive diffusion, active transport, and regulation of gene expression

• Osmosis and facilitated diffusion
