Cells: A Fundamental Unit of Life

What is the basic structural and functional unit of all living organisms?

• cell

• tissue

• molecule

• atom

Name the outermost covering of plant cells.

• Cell membrane

• Chloroplast

• Nucleus

• Cell wall

Which organelle is known as the powerhouse of the cell?

• Ribosomes

• Mitochondria

• Endoplasmic Reticulum

• Golgi Apparatus

What is the process by which a cell divides into two daughter cells?

• Fermentation

• Photosynthesis

• Mitosis or Meiosis

• Respiration

Differentiate between plant cells and animal cells.

• Plant cells have a nucleus, while animal cells do not.

• Animal cells have a cell wall, while plant cells do not.

• Plant cells have flagella, while animal cells do not.

• Plant cells have a cell wall and chloroplasts, while animal cells do not. Animal cells have centrioles, while plant cells do not.

Who proposed the cell theory?

• Isaac Newton and Galileo Galilei

• Matthias Schleiden and Theodor Schwann

• Charles Darwin and Alfred Russel Wallace

• Marie Curie and Albert Einstein

What are the three main parts of a cell?

• ribosome, lysosome, peroxisome

• cell membrane, cytoplasm, and nucleus

• cell wall, mitochondria, vacuole

• chloroplast, endoplasmic reticulum, Golgi apparatus

Explain the function of the nucleus in a cell.

• It is responsible for breaking down waste materials in the cell.

• It is the control center of the cell, storing the cell's DNA and coordinating cell activities.

• It is the powerhouse of the cell, producing energy for the cell.

• It is the site of protein synthesis in the cell.

What is the role of chloroplasts in plant cells?

• Chloroplasts are responsible for photosynthesis.

• Chloroplasts store water in plant cells.

• Chloroplasts are responsible for producing flowers in plant cells.

• Chloroplasts regulate the temperature of plant cells.

Describe the process of cell division in detail.

• Cell division is the process by which a parent cell divides into two or more daughter cells.

• Cell division is the process of a cell turning into a completely different type of cell.

• Cell division is the process of combining two parent cells into one daughter cell.

• Cell division is the process of a cell staying the same size and shape.
