1.	Chromosome.18. Given below is a diagram representing a stage duringmitotic cell division in an animal cell:NUCLEARMEMBRANEDISAPPEARS(i) Identify the above stage. Give a reason to supportyour answer.(ii) Name the cell organelle that forms the 'aster'.(iii) Name the parts labelled 1, 2 and 3.(iv) Name the stage that follows this stage of mitosis.How can this stage be identified ?(v) Mention two points of difference between'mitosis' and 'meiosis' with regard to :(1) The number of daughter cells formed.(2) The chromosome number in the daughtercells.[ICSE 2003]40 DifferentiatPlease find
Answer» Answer: 1) the above stage is late prophase... the nuclear membrane disappears in the late prophase only.. 2) the cell organelles that form the aster is centrosome.. 4) the stage that FOLLOWS prophase is metaphase... it can be identified by its characteristic FEATURE of the formation of metaphase PLATE. 5) 1.in mitosis 2 daughter cells are formed and in meiosis 4 daughter cells are formed 2.the chromosome number in mitotic cells are same as the mother cell and in meiosis the no of chromosome are halfed in daughter cells as compared to mother cells

Answer»

Answer:

1) the above stage is late prophase... the nuclear membrane disappears in the late prophase only..

2) the cell organelles that form the aster is centrosome..

4) the stage that FOLLOWS prophase is metaphase... it can be identified by its characteristic FEATURE of the formation of metaphase PLATE.

1.in mitosis 2 daughter cells are formed and in meiosis 4 daughter cells are formed

2.the chromosome number in mitotic cells are same as the mother cell and

in meiosis the no of chromosome are halfed in daughter cells as compared to mother cells
