Psyllium and Flum Functions in Cells

The video tutorial covers vocabulary notes on cell structures, focusing on the cell membrane, psyllium, and flum. It explains the functions of the cell membrane in providing shape and protection, the role of psyllium in cell movement, and the function of flum in single-celled organisms. Students are instructed to draw and label these structures while creating original sentences to reinforce learning.

What is the primary function of the cell membrane?

• To provide energy to the cell

• To give the cell its shape and protect it

• To store genetic information

• To produce proteins

How does the cell membrane interact with bacteria and viruses?

• It always blocks them from entering

• It allows them to enter freely

• It can be tricked into letting them in

• It destroys them immediately

Which of the following is NOT a function of the cell membrane?

• Producing energy for the cell

• Allowing selective entry and exit

• Protecting the cell from external threats

• Providing shape to the cell

What are psyllium and what is their function?

• They are storage units for nutrients

• They are energy-producing organelles

• They are tiny hairs that help cells move

• They are cell walls that provide structure

How do psyllium help cells move?

• By wiggling back and forth

• By producing energy

• By rotating in circles

• By expanding and contracting

What is a flum and how does it appear?

• A flum is a tail-like projection

• A flum is a cell wall that appears rigid

• A flum is a flat surface on the cell

• A flum is a circular organelle

Which cells typically have a flum?

• Cells that store nutrients

• All animal cells

• Cells that need to move around

• All plant cells

What is the main difference between psyllium and flum?

• Both are hair-like

• Psyllium are tail-like, flum are hair-like

• Psyllium are hair-like, flum are tail-like

• Both are tail-like

What is the role of the flum in single-celled organisms?

• To help the organism move

• To produce energy

• To store genetic material

• To protect the organism from harm

How does the flum help in the movement of cells?

• By expanding and contracting

• By moving back and forth

• By rotating in circles

• By producing energy
