14777.	Question : Mitotic spindle is mainly composed of __ proteins.
Answer» tublin myosin actin actomyosin Solution :SPINDLE fibres are structures formed from mictrobubules in the CYTOPLASM during cell division. Microtubules are MADE up of tubulin protein.

Discussion

14778.	Question : Mitosis takes place regularly in somatic cells, whereas meiosis occurs only in germ cells.
Answer» ANSWER :1

Discussion

14779.	Question : Mitosis results in producing two cells which are similar to each other. What would be the consequence if each of the following irregularities occur during mitosis? (a) Nuclear membrane fails to disintegrate (b) Duplication of DNA does not occur (c) Centromeres do not divide (d) Cytokinesis does not occur
Answer» Solution :(a) If nuclear membrane does not integrate then spindle fibres reach till chromosomes and they can not move towards opposite pole. In some protozoans spindle fibres are made in nucleus only. It is called inter nuclear mitosis. (b) If DNA replication does not take place then cell can not go further. Then S-phases formation of chromosomes does not takeplace and can not enter into M-phase. (c) If centromere does not DIVIDE then one daughter cell from two gets complete set of chromosomes. Other cell LACKS it due to this trisomy can be SEEN. (d) If cytoplasmic division OCCURS then multinucleate state means coenocytes can be seen and syncytium can be formed eg.Rhizopus and Vaucheria.

Discussion

14780.	Question : Mitosis is charecterised by

Discussion

14781.	Question : Mitosis is necessary for growth, development and repair of the cell.
Answer» Solution : The beginning of life of living organism is done from UNICELLULAR zygote stage. New cells are added in the BODY of living organism DUE to CELL division. Growth is also seen in living organism. New cells are added by mitosis in the place of wounded cells or cells which are destroyed due to any reason. All these cells are like parent cell in STRUCTURE and genetic composition.

Discussion

14788.	Question : Why Mitochondira is called as 'the power house of a cell'?
Answer» Solution :Complete oxidation of a glucose molecule in aerobic respiration results in the net gain in 36 ATP molecules in planst. SINCE huge AMOUNT of energy is generated in mitochondria in the form of ATP molecules they are called 'Power house of the cell'. In the case of aerobic PROKARYOTES due to lack of mitochondria of glucose produces 38 ATP molecules.

Discussion

14789.	Question : Why are mitochondria called the powerhouse of the cell?
Answer» Solution :Protein, lipid and enzymes working on carbohydrates, RNA and DNA in small amount are also seen in MITOCHONDRIA. Mitochondria mainly does three functions: (i) Produces cellular ENERGY in the form of ATP and releases as PER needed. (II) Collect ATP energy and transform it and translocate it. (iii) Regulate active transport of each substances occurring in cell membrane. Mitochondria is considered as small biochemical factory generating ATP from food, ADP and oxygen. During chemical process, the molecules of glucose are combusted and 38 molecules of ATP are obtained The matrix of mitochondria contains necessary enzymes for crab.s cycle. Here ATP is synthesized. Therefore mitochondria is called powerhouse of the cell.

14796.	Question : Mitochondria are called powerhouses of the cell. Which of the following observations supports thisstatement ? (A) Mitochondria synthesis ATP (B) Mitochondria have a double membrane (C) The enzymes of the Krebs cycle and the cytochromes are found in mitochondria (D) Mitochondria are found in almost all plants and animal cells.
Answer» Mitochondria synthesis ATP Mitochondria have a doublemembrane The enzymesof the Krebs cycle and the cytochromes are found in mitochondria Mitochondriaare foundin ALMOST all plants and ANIMAL cells. Answer :A::C::D

Discussion

14797.	Question : Mitochondria are found in all .......cells.
Answer» SOLUTION :EUKARYOTIC

Discussion

14798.	Question : Mitochondria are aptly called 'power houses' of the cell.
Answer» Solution :MITOCHONDRIA are the SITES of aerobic respiration. They produce cellular ENERGY in the form of ATP, hencethey are CALLED .power houses. of the cell.

Discussion

14799.	Question : Mitochondria are also called as
Answer» Lipochondria Sarcoplasm Chondriosomes MICROBODIES ANSWER :C

Discussion

14800.	Question : Assertion: Mitochondrial DNA is similar to prokaryotic DNA. Reason: Mitochondria are thought to have evolved from the prokaryotes.
Answer» these organelles CONTAIN cristae or thylakoids these organelles contain electron transport chain the genetic CODE in these organelles is same as in all ORGANISMS the ribosomes in these organelles share propertieswith those of PROKARYOTES Solution : the ribosomes in these organelles share propertieswith those of prokaryotes
