What is the role of the nucleus in a cell?
The nucleus generates energy for the cell.
The nucleus synthesizes proteins for cellular functions.
The nucleus transports nutrients throughout the cell.
The nucleus controls cell activities and stores genetic information.
What type of cell lacks a nucleus?
Prokaryotic cells (e.g., bacteria)
Red blood cells (mature)
Fungal cells (e.g., yeast)
Eukaryotic cells (e.g., plants)
Name one type of eukaryotic cell.
Animal cell
Plant cell
Bacterial cell
Fungal cell
What is the function of ribosomes?
The function of ribosomes is to break down waste products.
The function of ribosomes is to synthesize proteins.
The function of ribosomes is to transport nutrients.
The function of ribosomes is to store genetic material.
What structure gives plant cells their shape?
Cell wall
Cell membrane
Chloroplast

How do prokaryotic cells reproduce?
Prokaryotic cells reproduce via spore formation.
Prokaryotic cells reproduce by budding.
Prokaryotic cells reproduce through mitosis.
Prokaryotic cells reproduce by binary fission.
What is the main difference between prokaryotic and eukaryotic cells?
Prokaryotic cells have membrane-bound organelles; eukaryotic cells do not.
Prokaryotic cells lack a nucleus; eukaryotic cells have a nucleus.
Eukaryotic cells are smaller than prokaryotic cells in size.
Prokaryotic cells contain multiple chromosomes; eukaryotic cells have a single chromosome.
What organelle is involved in protein synthesis?
Ribosome
Lysosome
Golgi apparatus
Mitochondria
What is the function of the cell wall in plant cells?
The cell wall aids in photosynthesis and nutrient absorption.
The cell wall provides structural support and protection to plant cells.
The cell wall stores energy and synthesizes proteins for the cell.
The cell wall regulates the movement of water and ions in cells.
Name a type of prokaryotic organism.
Archaea
Protozoa
Bacteria
Fungi
What is the role of lysosomes in a cell?
Lysosomes digest and recycle waste materials and cellular debris.
Lysosomes produce energy for the cell.
Lysosomes store genetic information.
Lysosomes transport proteins to the nucleus.
What type of cells are found in multicellular organisms?
Only plant cells are found in multicellular organisms.
All cells are identical in structure.
Various specialized cells such as muscle cells, nerve cells, epithelial cells, and connective tissue cells.
Only single-celled organisms exist.
What is the function of the endoplasmic reticulum?
The endoplasmic reticulum transports waste products.
The endoplasmic reticulum synthesizes proteins and lipids.
The endoplasmic reticulum stores genetic material.
The endoplasmic reticulum generates energy for the cell.
What is the purpose of the Golgi apparatus?
The Golgi apparatus generates energy for the cell.
The Golgi apparatus is responsible for DNA replication.
The Golgi apparatus transports waste materials out of the cell.
The purpose of the Golgi apparatus is to modify, sort, and package proteins and lipids for secretion or delivery to other organelles.
How do cells communicate with each other?
Cells exchange information through physical barriers.
Cells communicate with each other through direct contact, chemical signals, and electrical signals.
Cells rely solely on sound waves for communication.
Cells communicate using only visual signals.
