What role does the nucleus play in ensuring a cell can successfully divide?

• The nucleus generates the proteins required for cell division.

• The nucleus stores the genetic instructions necessary for cell division.

• The nucleus regulates the entry of nutrients needed for cell division.

• The nucleus synthesizes the lipids needed for cell division.

In biology class, students learned that nerve cells are crucial for sending signals quickly across the body. These cells rely on specific organelles to manage the flow of chemicals. Which organelle is primarily responsible for this function?

• the mitochondria because they generate energy for the cell's activities

• the cell membrane because it regulates the entry and exit of substances

• the ribosomes because they synthesize proteins needed for cell function

• the endoplasmic reticulum because it transports materials within the cell

Why is it necessary for animal cells to have multiple organelles to manage the intake, utilization, and expulsion of nutrients?

• Cells need to adapt to a wide range of environmental conditions and food types.

• Each organelle has a unique role that contributes to the overall cellular process.

• The sheer amount of nutrients is too much for a single organelle to handle.

• Organelles develop their functions over time, leading to diverse roles.

What cellular process is crucial for expelling waste to sustain homeostasis?

• cell division

• cellular respiration

• excretion of waste

• nutrient absorption

What effect would increasing the number of chloroplasts in a plant cell model have?

• The cell would produce more energy through photosynthesis.

• The cell would have more genetic material.

• The cell would be better at regulating water intake.

• The cell would be more effective at waste removal.
