Sample Cell Organelles Worksheet Answers and Explanations
Below are examples of common questions found in worksheets and their detailed answers to aid your understanding.
Question 1: Label the Diagram of a Cell
Given a diagram, identify and label the following parts: nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosome, ribosome, cell membrane.
Answer:
- Nucleus: Usually the largest organelle, often centrally located; contains DNA.
- Mitochondria: Bean-shaped with internal folds called cristae; responsible for energy production.
- Endoplasmic Reticulum: Network of membranous tubules; rough ER has ribosomes attached, smooth ER does not.
- Golgi Apparatus: Stack of flattened membrane sacs; modifies and packages proteins.
- Lysosome: Small, spherical organelle containing digestive enzymes.
- Ribosomes: Tiny dots attached to rough ER or floating freely; sites of protein synthesis.
- Cell Membrane: Outer boundary of the cell; controls substance entry and exit.
Question 2: What is the Function of the Mitochondria?
Answer:
Mitochondria are known as the "powerhouses" of the cell because they generate most of the cell's supply of adenosine triphosphate (ATP), which provides energy for various cellular processes. They also play roles in apoptosis (programmed cell death) and metabolic regulation.
Question 3: Compare Plant and Animal Cells
- Plant Cells: Have chloroplasts, a cell wall, and a large central vacuole.
- Animal Cells: Lack chloroplasts and cell walls; have smaller vacuoles.
Answer:
Plant cells contain chloroplasts for photosynthesis and a rigid cell wall for support, while animal cells do not. Both contain nuclei, mitochondria, endoplasmic reticulum, and other common organelles.
Question 4: Describe the Role of the Endoplasmic Reticulum
Answer:
The endoplasmic reticulum (ER) functions in the synthesis and transport of proteins and lipids. The rough ER, studded with ribosomes, specializes in protein production, while the smooth ER is involved in lipid synthesis and detoxification.
Tips for Using Cell Organelles Worksheets Effectively

Frequently Asked Questions
What is the primary function of the nucleus in a cell?
The nucleus acts as the control center of the cell, containing genetic material (DNA) and regulating gene expression and cell activities.
How does the mitochondria contribute to cell energy production?
Mitochondria are known as the 'powerhouses' of the cell because they generate ATP through cellular respiration, providing energy for the cell's functions.
What role do ribosomes play in the cell?
Ribosomes are responsible for protein synthesis, translating genetic information into amino acid chains to build proteins.
Why is the endoplasmic reticulum important in a cell?
The endoplasmic reticulum (ER) assists in the synthesis, folding, and transport of proteins and lipids; the rough ER has ribosomes attached for protein production.
What is the function of lysosomes in a cell?
Lysosomes contain digestive enzymes that break down waste materials and cellular debris, helping to clean up the cell.
How do chloroplasts function in plant cells?
Chloroplasts carry out photosynthesis, converting sunlight, carbon dioxide, and water into glucose and oxygen, providing energy for the plant.
What is the role of the cell membrane?
The cell membrane controls what enters and exits the cell, providing a protective barrier and maintaining homeostasis.
What is the purpose of the Golgi apparatus?
The Golgi apparatus modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.
How do vacuoles function in plant and animal cells?
Vacuoles store nutrients, waste products, and other materials; in plant cells, a large central vacuole also maintains turgor pressure to support the structure.
