If the cells are from a bean plant, which process could the student observe ?, The formation of a cell plate between two new cells, The replication of centrioles, A pinching-in of the cell membrane to form two cells, The pairing of homologous chromosomes, I - The eukaryotic ribosome is 80S. what does this ‘S’ denote?, Supernatant coefficient, Segregation coefficient, Solidification coefficient, Sedimentation coefficient, A - How many microtubules does the flagella contain?, 6 + 5, 8 + 3 , 9 + 2, 7 + 4, B - Which of these structures are absent in eukaryotes?, Organised nucleus, Membrane bound organelles, Mesosome, Nuclear envelope, C - Which of the following is an advantage eukaryotes have over prokaryotes?, Increased compartmentalization allowing for specialization, Improved cell motility due to protein-based flagella, Streamlined transcription / translation process due to clear step-wise mechanism, Increased stability of genetic information due to double-stranded DNA, D - A student is examining an onion root tip cell under a microscope. Based on her observations, the student proposes that the onion root tip cell has completed interphase and is now in the first phase of mitosis., The cell’s DNA is dispersed within the nucleus as chromatin, Separated sister chromatids are being pulled towards opposite ends of the cell, Discrete chromosomes are scattered throughout the cell’s nucleus, The cell’s chromosomes are aligned across the metaphase plate, E - In eukaryotic cells, ribosomes are, 50S + 40S, 80S, 60S + 30S, 70S, F - Which of the following cellular structures is not seen in both prokaryotes and eukaryotes?, cell wall, DNA , mitochondria, ribosomes, G - A group of researchers in a laboratory have found what they believe to be an unknown organism. They notice that this organism lacks a nuclear membrane and mitochondria. Using this information, which of the following structures would this organism most likely possess?, endoplasmic reticulum, ribosomes, cilia, lysosome, I - Which of the following is not an example of a eukaryotic cell?, parenchyma cell, E.coli cell, human epithelial cell, myocyte, A - Compartmentalization of DNA within the cell occurs in which of the following cell types?, archaeal, bacterial, eukaryotic, prokaryotic, B - Which of the following groups include single-celled eukaryotes?, plantae, protista, bacteria, archaea, C - Which of the following cell cycle descriptions is CORRECT?, chromosomes are replicated during G1 phase, the order of stages of cell cycle is G1 followed by S followed by G0 and M phase., the s phase consists of prophase, metaphase, anaphase and telopase, interphase is when the cell spends most of its time performing its cell function, D - What would happen if the G2 phase didn’t function properly?, no cellular proteins made, DNA would not be replicated, the spindle fibre would not form, the chromosomes will not align at the equator, E - Organelles are membrane-bound structures found only within the cells of eukaryotes. These structure provide different functions within the cell. Which of the following is not considered an organelle? , chloroplast, peroxisome, ribosome, nucleus, F - During what process do eukaryotic cells become haploid?, nondisjunction, s phase, meiosis 1, meiosis 2, G - , 6, 1, 2, 4, I - , 1, 2, 3, 4, A - Which description of mitosis is incorrect?, centrioles migrate to opposite sides of the cell during prophase, in synthesis phase, the chromosomes replicate, metaphase is the stage in which pairs of chromatids line up on the equatorial plate., n anaphase, the chromosomes arrive at the opposite poles of the cell..
