Students prepared a slide of onion root tip.There were many cells seen under microscope. There was a cell with two groups of chromosomes moving towards opposite ends of the cell. This cell is in which phase of mitosis?

All chromosomes are arranged parallel to equatorial plane of cell in ____ phase of mitosis.

Fill in the blanks and explain the statements. All chromosomes are arranged parallel to equatorial plane of cell in -- -- -- phase of mitosis.

If an onion has 16 chromosomes in its leaf cell, how many chromosomes will be there in its root cell and pollen grains.

While"observing a slide,student observed many cells with nuclei. But some of the nuclei were bigger as compared to others but their nuclear membrane was not so clear. Teacher inferred it as one of the phase in the cell division. Which phase may be inferred by teacher?

Choose the correct alternate and write its alphabet against the sub question number: All chromosomes are arranged parallel to equatorial plane of cell in .............. phase of mitosis

In eukaryotes, the process of division of a somatic parent cell into two daughter cells is known as mitosis. During the M or mitosis phase of a cell cycle, the chromosomes present in the nucleus are separated into two identical sets, which eventually form two daughter nuclei. This is followed by cytokinesis. Onion root tips are most commonly used to observe the different stages of mitosis in the laboratory. Each onion cell contains a total of eight chromosomes. DNA specific stains are used to visualise these chromosomes in different phases of mitosis. Name the stain that can be used to observe the different phases of mitosis.

In mitosis, a cell having 2n chromosomes, would form daughter cells having how many chromosomes ?

Name the stage of cell cycle at which one of the folloiwng events occur : Chromosomes are moved to spindle equator.

A potentiometer wire is 100 cm long hand a constant potential difference is maintained across it. Two cells are connected in series first to support one another and then in opposite direction. The balance points are obatined at 50 cm and 10 cm from the positive end of the wire in the two cases. The ratio of emfs is:

How many mitotic divisions occur in a cell of the root tip to form 256 cells
