MCQs-Biology-Plant cell Welcome to your MCQs-Biology-Plant cell. All the best, show your best! How the genetic information of the DNA can be used for biological function? All of the above By translation the message from mRNA to protein By replicating the DNA I & II By transcribing the message to mRNA None Primary cell walls are synthesised during the active cell growth True False None Why DNA is a genetic material It can be inherited across the generations It functions in cell physiology Because it encodes proteins It is a long molecule None Huge plant structures can be attributed to which of the following biomolecule? Lignin Modified sugars Carbohydrates Amines None Perinuclear space in plant cell is All of the above A space between the membranes of the nuclear envelop A space between the nuclear membrane and cellular membrane Cytoplasm None Nucleus is a site of Storage of genetic material All of the above. DNA replication Transcription None Which of the following is a function of root Anchorage Absorption of minerals All of the above Absorption of water None Which of following is NOT true for secondary plant cell wall as compared to primary cell wall? Secondary cell walls are indicator of actively growing cells Secondary cell walls are stronger Secondary cell walls are thicker None of the above None Identify the correct sequence of DNA packaging? A. Wrapping of DNA around histones to form nucleosomesB. Formation of chromatin fibrC. Coiling CAB BCA ABC CBA None Leaves of the stem are attached at the region Internode Branch point Lesion Node None Which of the following cells are oxygen producer? Pollen Green plant cells Roots None of the above None Which of the following property of primary plant cell walls does NOT account for its function? It is strong enough to bear a turgor pressure It is extensible and sustain cell enlargement It keeps on growing in the cells with ceased growth Chemically active to link to the external cellular matrix None Condensed chromatin is observed during Mitosis Meiosis DNA repair I & II Replication None Two cells in plant tissue are cemented together by Peptidoglycan Middle lamella Cellular membrane Primary cell wall None Signal recognition sequence directs the ribosome complex to Rough endoplasmic reticulum Smooth endoplasmic reticulum Nucleus Cytoplasm None Time's up
