Understanding Human Cells

In a nursing class, the instructor explains that all living organisms are composed of smaller units. During a discussion, a student asks, 'What is the fundamental unit of life that constitutes all living things?'

• Organ

• Cell

• Organism

• Tissue

In a nursing class, students are learning about cellular functions. During a discussion about energy production in cells, the instructor asks: Which organelle is commonly referred to as the powerhouse of the cell?

• Chloroplast

• Ribosome

• Nucleus

• Mitochondria

As a nursing student, you are learning about cell biology. You observe that certain substances are rapidly entering and leaving a cell. Which structure is responsible for regulating the movement of these substances in and out of the cell?

• Ribosome

• Cytoplasm

• Nucleus

• Cell membrane

In a nursing class, students are learning about the different components of a cell. During a discussion, the instructor asks, "Which part of the cell contains genetic material?"

• Ribosomes

• Mitochondria

• Endoplasmic reticulum

• Nucleus (in eukaryotic cells) or nucleoid (in prokaryotic cells)

In a clinical setting, nurses often collaborate with scientists who are developing new medications. These researchers depend on tiny structures within cells called ribosomes to assist in creating the proteins essential for their studies. What role do ribosomes play in this scenario?

• To transport nutrients within the cell.

• To generate energy for cellular processes.

• The role of ribosomes is to synthesize proteins.

• To store genetic information.

In a nursing class, students are learning about cellular functions and their significance in human health. During a lab session, they observe the process of protein synthesis under a microscope. Which organelle are they likely observing that plays a vital role in this essential process?

• Ribosome

• Mitochondria

• Golgi apparatus

• Lysosome

In a nursing class, students are learning about the different components of a cell. During a lab demonstration, the instructor points out the jelly-like substance that fills the cell and holds the organelles in place. What is this substance called?

• ribosome

• nucleus

• cell membrane

• cytoplasm

In a nursing class, the instructor discusses the role of cells in the human body and highlights the significance of energy production for various physiological processes. She asks the students to identify which part of the cell is primarily responsible for generating energy.

• Nucleus

• Ribosome

• Cell membrane

• Mitochondria

As a nursing student, you are learning about the importance of cell membranes in maintaining cellular health. You observe that the cell membrane selectively allows certain substances to enter while keeping others out. This behavior is essential for the cell's survival and function. What is the primary function of the cell membrane?

• To produce energy for the cell.

• To regulate the movement of substances in and out of the cell.

• To store genetic information.

• To provide structural support to the cell.

In a nursing class, students are learning about cell theory. They discuss how all living organisms, from the smallest bacteria to the largest mammals, share certain characteristics. What is true about all living organisms according to cell theory?

• All living organisms can survive without cells.

• All living organisms are composed of only one type of cell.

• All living organisms are composed of one or more cells.

• All living organisms are made of tissues and organs.
