Prokaryotic and Eukaryotic Cell Functions

The video tutorial explains the fundamental characteristics of prokaryotic cells, highlighting that their DNA is dispersed throughout the cytoplasm rather than contained within a nucleus. It describes the roles of the cell membrane and cytoplasm, the nucleoid where DNA is concentrated, and the function of flagella in cell movement. The video concludes by encouraging viewers to continue learning and subscribe to the educational channel.

What is the primary characteristic of prokaryotic cells?

• They have a defined nucleus.

• Their DNA is spread throughout the cytoplasm.

• They have multiple chromosomes.

• They lack a cell membrane.

Which substance is found inside the cell membrane and contains organelles?

• Ribosomes

• Nucleus

• Cytoplasm

• Mitochondria

What is one of the main functions of the cell membrane?

• To provide structure and protection

• To produce energy

• To store genetic information

• To synthesize proteins

Where is the DNA found in prokaryotic cells?

• In the ribosomes

• In the nucleus

• In the nucleoid

• In the mitochondria

What is the role of genes in DNA?

• To protect the cell

• To provide energy

• To store hereditary information

• To transport nutrients

What is the function of the flagellum in some cells?

• To store genetic material

• To produce proteins

• To help the cell move

• To protect the cell

Which type of cells can have a flagellum?

• Only prokaryotic cells

• Neither prokaryotic nor eukaryotic cells

• Only eukaryotic cells

• Both prokaryotic and eukaryotic cells
