Maharashtra Board Solutions for Chapter: Cell Division, Exercise 10: Exercise

While observing a slide, students 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 phases in the cell division. Which phase may be inferred by the teacher? 

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

With the help of suitable diagram, describe the cell cycle.

Distinguish between mitosis and meiosis and draw labelled diagrams.

Draw the diagram of metaphase and write explanation.

Is the given figure correct? Why?

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

Identify the following phases of mitosis and label the '$A$' and '$B$' given in diagrams.
