Cell Structure and Function Concepts

The video tutorial covers the differences between eukaryotic and prokaryotic cells, focusing on their structures and functions. It explains organelles, cell membranes, and ribosomes, and compares plant, animal, and bacterial cells. The teacher also discusses DNA forms like chromatin, chromatid, and chromosomes, and highlights the presence of cell walls and chloroplasts in certain cells. The session concludes with a reminder of upcoming Zoom meetings and a review of organelles.

What is a key difference between eukaryotic and prokaryotic cells?

• Prokaryotic cells are found in complex organisms.

• Prokaryotic cells have a nucleus.

• Eukaryotic cells lack a nucleus.

• Eukaryotic cells are generally larger.

Which of the following is true about organelles?

• They do not work together within a cell.

• Each organelle has a specific function.

• Organelles are only found in plant cells.

• They are the same in all cell types.

In which type of cell is DNA typically found in a plasmid?

• Animal cells

• Plant cells

• Bacterial cells

• All of the above

What is the primary function of the cell membrane?

• To produce energy

• To control what enters and exits the cell

• To store genetic information

• To provide structural support

Which cell types contain ribosomes?

• Only bacterial cells

• Only animal cells

• All cell types

• Only plant cells

Which cells have a cell wall?

• Animal cells only

• Plant and bacterial cells

• All cell types

• None of the above

What is the role of chloroplasts in cells?

• To photosynthesize and produce glucose

• To produce proteins

• To store water

• To protect the cell

What is chromatin?

• A type of organelle

• Unraveled DNA in the nucleus

• A protein maker

• Condensed DNA

What are sister chromatids?

• Proteins in the cell

• Unrelated DNA strands

• Exact copies of each other

• Different types of DNA

Where are specific genes located within DNA?

• On specific chromosomes

• In the cell membrane

• On any chromosome

• In the cytoplasm
