MCQs-Biology-Plant cell Welcome to your MCQs-Biology-Plant cell. All the best, show your best! Which of the following cells are oxygen producer? Pollen None of the above Green plant cells Roots None Why DNA is a genetic material Because it encodes proteins It can be inherited across the generations It functions in cell physiology It is a long molecule None Primary cell walls are synthesised during the active cell growth False True 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 Chemically active to link to the external cellular matrix It keeps on growing in the cells with ceased growth It is extensible and sustain cell enlargement None Identify the correct sequence of DNA packaging? A. Wrapping of DNA around histones to form nucleosomesB. Formation of chromatin fibrC. Coiling BCA ABC CAB CBA None Nuclear membrane Encloses all the plant cell genome Is a double membrane structure Encloses a nuclear genome I & III None Signal recognition particle is required for protein degradation Nuclear transcription stability of mRNA Direction of the ribosome complex to rough endoplasmic reticulum None Choose one of following for semiautonomous organelles All of the above They contain their own genome They are partly dependent on nuclear genome Some of them can produce their own food None Bryophytes cannot form larger plant architecture because of Absence of extra cellular matrix Absence of lignin Absence of Cellulose Presence of Cellulose inhibitory compounds None How the genetic information of the DNA can be used for biological function? By translation the message from mRNA to protein All of the above By replicating the DNA I & II By transcribing the message to mRNA None Which of the following is a function of root All of the above Absorption of water Absorption of minerals Anchorage None Endoplasmic reticulum is present in Alongside the plasma membrane Mitochondrion Vacuole Outside nucleus None Which of the following cellular component is rich in lignin content? Vacuole Primary cell wall Secondary cell wall Cell membrane None What is internode Length of the stem between two nodes Length between shoot tip and stem base Distance of first branch from the soil All of the above, None Huge plant structures can be attributed to which of the following biomolecule? Modified sugars Carbohydrates Lignin Amines None Time's up
