Welcome to your AQA AS Biology 3 1. A major structural difference between an eukaryotic cell and a prokaryotic cell. Presence of cell vacuole in eukaryotic cells. Presence of one or more flagella in many prokaryotic cells. Presence of a nucleous in eukaryotic cells. Presence of smaller ribosomes in prokaryotic cells.2. Which is not a basic concept of cell theory? Cells are the units of structure (building blocks) of all animals and plants. Cells originate only from pre-existing cells by cell division. Some cells maintain homeostasis. Cells are the smallest unit of function in all animals and plants.3. Choose the correct order of cell arrangement in complex multicellular organisms. Organs, cells, systems, tissues Tissues, organs, cells, systems Cells, tissues, systems, organs Cells, tissues, organs, system4. The site of ribosome formation. Nucleolus Vacuole Cytoplasm Endoplasmic reticulum5. Prokaryotic cells have a single ___________ instead of a nucleus. Flagellum Capsule Circular DNA molecule Cell membrane6. Which of the following is a major difference between plant and animal cells? Plant cells have a cell wall. Most plant cells do not contain cilia. Plastids are absent in animal cells. Centrioles are present in all animal cells.7. Components of cytoskeleton. Microtubules only Microtubules and vescicles Microtubules and microfilaments Microfilaments and ions8. How is rough ER different from smooth ER? Present only in plant cells. Presence of cisternae. Presence of double membranes. Presence of ribosomes9. Which organelle is referred as the 'Powerhouse of the cell'? Ribosomes Mitochondria Nucleus Cytoplasm10. In complex multicellular organisms, eukaryotic cells become _________ for specific functions. Turgid Smaller Specialised Bigger11. What are the organelles assisting in cell locomotion? Cilia and lysosomes Cilia and flagella Flagella and plasmids Cilia only12. Which of the following is not correctly paired? Smooth endoplasmic reticulum-processing, packaging, secretion Rough endoplasmic reticulum-protein synthesis Chloroplast-photosynthesis Nucleus-cellular reproduction13. Select the correct statement with regard to chloroplasts. Chloroplasts have a system of three membranes. Chloroplast is a single membrane bound organelle. The thylakoid system is a collection of membranous sacks called stroma. The outer membrane of the chloroplast is permeable to larger proteins.14. Network of tiny tubes within the cytoplasm. Plasmids Cytoskeleton Cytosol Vacuole15. Component of plant cell wall. Cellulose Lignin Hemicellulose Pectin16. What is the function of cell wall in a plant cell? It strengthens the cell. It keeps the cell turgid. It aids in photosynthesis. Transpiration.17. The site of chromosomes. Cell wall Cytoplasm Nucleus Ribosomes18. Function of ribosomes. Exchange of gaseous materials. Protein synthesis Controls the activities of the cell. Most chemical processes take place here.19. Which of the following is found in plant cells but not in bacteria? Ribosomes RNA Mitochondria Cell membrane20. The site of chlorophyll. Outer membrane of the chloroplast Inner membrane of the chloroplast Thylakoids Stroma of the chloroplast21. Select the incorrect statement regarding haemoglobin. Each polypeptide chain of haemoglobin contains a haem group. Haemoglobin does not contain a prosthetic group. Haem group is responsible for the color of haemoglobin. Each haem group contains an iron atom.22. Which is not a function of golgi bodies? Intracellular digestion Determining which proteins are to be transported outside the cell. Packaging macromolecules for delivery to other organelles. Sorting and processing proteins.23. Many prokaryotic cells do not have __________________. Microtubules One or more flagella A capsule surrounding the cell One or more plasmids24. Select the incorrect sentence out of the following. Flagella is present in all plant cells. Golgi bodies are present in both animal and plant cells. A large central vacuole is present in plant cells. Cell membrane is present in both animal and plant cells.25. Cristae are structures found in the __________. RNA Actin fiber Golgi bodies MitochondriaTime is Up!
