The smalI rounded knob like fragment in a chromosome lying beyond the secondary constriction is Centromere Kinetochore Satellite Telomere 2. Membrane bound minute vesicles with enzymatic matrix present in both plant and animal cells Microbodies Microsomes Ribosomes Plastids 3. The cell organelle which facilitates locomotion in certain eukaryotic animal cell is Cilia Flagella Centrosome Centriole 4. The cell organelle which helps in oxidative phosphorylation is Chloroplast Mitochondria Ribosome ER 5. Energy transducing cell organelles in a cell are Chloroplast Mitochondria Ribosome 1 and 2 6. 90 percent of the volume of the mature plant cell is occupied by Cytoplasm Nucleus Vacuole Cell membrane 7. Nucleus as a cell organelle was first described by Robert Hooke Robertson Rausburg Robert Brown 8. Na+ and K + pumping across the membrane is a/an Passive transport Active transport Diffusion None of these 9. Identity the incorrect statement among the following Nissil granules are associated with protein synthesis Autolysis of cell is promoted by perinuclear dense bodies Golgi complex is involved in secretion of cell wall materials Golgi complex is also called dictyosome in invertebrates only 10. Regarding the functions of S.E.R, the untrue statement of the following is Detoxification of foreign substances of cell Intra-cellular transportation of materials Provide precursors to dictyosome Synthesis of Glycoproteins & Glycolipids 11. Organelles which are synthesised at one place and move away and show their activity at a different, place in the cell are Lysosomes Endoplasmic reticulum Mitochondria Ribosomes 12. Choose the incorrect statement Primary cell wall is formed between middle lamellum and plasma membrane. Middle lamellum is formed between primary walls of adjacent cells. Cell wall is not always three layered. Secondary cell wall is formed between primary cell wall and plasma membrane. 13. Identify the mis-match of the following Palade granules – cell organelle with non-genetical nucleic acid Power house of a cell-cell organelle with both genetic & non-genetic nucleic acids. Nucleolus – Cell organelle with genetic & non-genetic nucleic acids. Chromosome – Cell constituent with genetic nucleid acids. 14. Cell theory as proposed by Schleiden & Schawann does not explain. Cell is the structural unit of all organisms. All cells arise from pre-existing cells. Cell is the functional unit of all living organisms. All living organisms are composed of cells and products of cells. 15. Choose the incorrect statement: Ribosome is the non-membrane bound cell organelle found in all types of living cells. Centrioles are the only non-membrane bound cell organelles present in animal cells. Non-membrane bound cell organelles are found in animal cells only are centrioles All the above 16. “The term ‘thylakoid”” refers to “ A stack of coins Any membrane of the chloroplast Stororma which contains flattened sacs Flattened membranous sacs 17. “With reference to ribosomes, “”S”” is an indirect measures of” Size and shape Structure and function Density and size Protein synthesizing efficiency 18. Molecules that move through the nuclear pores are DNA and RNA RNA and proteins Chromatin and ribosomes Pigments Loading … Related posts: Cell The Unit of Life Test No-3 Cell The Unit of Life Test No-4 Cell The Unit of Life Test No-5 Cell The Unit of Life Test No-12 Cell The Unit of Life Test No-13 Powered by YARPP.
