Total questions: 10
Worksheet time: 5mins
What is the basic unit of life?
Organism
Organ
Tissue
Cell
Describe the structure of the cell membrane.
The cell membrane consists solely of cholesterol molecules.
The cell membrane is a rigid structure made of cellulose.
The cell membrane is a single layer of phospholipids without proteins.
The cell membrane is a phospholipid bilayer with embedded proteins, creating a semi-permeable barrier.
What organelle is known as the powerhouse of the cell?
Chloroplast
Nucleus
Ribosome
Mitochondria
Explain the function of ribosomes in a cell.
Ribosomes help in the transport of nutrients across the cell membrane.
Ribosomes act as the cell's energy production center.
Ribosomes are responsible for DNA replication.
Ribosomes function as the site of protein synthesis in a cell.
What is the role of the nucleus in a cell?
The nucleus controls cell activities and contains genetic material.
The nucleus is responsible for protein synthesis.
The nucleus produces energy for the cell.
The nucleus helps in the digestion of nutrients.
Define the term 'cytoskeleton' and its function.
The cytoskeleton is a type of organelle that produces energy for the cell.
The cytoskeleton is a fluid that fills the cell and provides nutrients.
The cytoskeleton is a structural network in cells that supports shape, movement, and transport.
The cytoskeleton is a membrane that protects the cell from external damage.
What are the differences between prokaryotic and eukaryotic cells?
Prokaryotic cells contain membrane-bound organelles; eukaryotic cells do not.
Eukaryotic cells are smaller than prokaryotic cells.
Prokaryotic cells have a nucleus; eukaryotic cells do not.
Prokaryotic cells lack a nucleus and organelles; eukaryotic cells have a nucleus and organelles.
Name the process by which cells divide.
DNA Replication
Protein Synthesis
Mitosis and Meiosis
Cellular Respiration
What is the function of lysosomes?
To synthesize proteins for cellular functions
The function of lysosomes is to digest and break down waste materials and cellular debris.
To produce energy for the cell
To store genetic information
Describe the role of mitochondria in cellular respiration.
Mitochondria store genetic information for the cell.
Mitochondria are involved in protein synthesis.
Mitochondria are responsible for photosynthesis in plants.
Mitochondria convert nutrients into ATP through cellular respiration.
