A student is given a diagram of a cell and asked to identify the structure that allows certain substances to pass in and out while blocking others. How should the student explain the importance of this structure for cell survival?

• It keeps the cell warm.

• It allows the cell to control its internal environment by regulating what enters and leaves, which is essential for maintaining balance and proper function.

• It helps the cell move.

• It stores food for the cell.

Imagine a cell loses all of its mitochondria. Predict and explain what would happen to the cell’s ability to function.

• The cell would continue to function normally.

• The cell would lose its ability to produce energy efficiently, leading to cell death because mitochondria are responsible for energy production.

• The cell would become larger.

• The cell would start making more proteins.

Given a list of structures: heart, muscle tissue, muscle cell, circulatory system, and human body, organize them from the smallest to the largest level of organization and explain your reasoning.

• Human body, circulatory system, heart, muscle tissue, muscle cell; because the body is made of systems, which are made of organs, which are made of tissues, which are made of cells.

• Muscle cell, muscle tissue, heart, circulatory system, human body; because cells make up tissues, tissues make up organs, organs make up systems, and systems make up the body.

• Heart, muscle cell, muscle tissue, circulatory system, human body; because the heart is the smallest.

• Circulatory system, heart, muscle tissue, muscle cell, human body; because systems are the smallest.
