Students were shown some slides of cancerous cells. Teacher made a comment as if there would have been a control at one of its cell cycle phase, there wouldn’t have been a condition like this. Which phase the teacher was referring to?
Students prepared a slide of onion root tip. There were many cells seen under microscope. There was a cell seen under microscope. There was a cell with two groups of chromosomes at opposite ends of the cell. This cell is in which phase of mitosis?
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?
How does cytokinesis in plant cells differ from animal cells?
What is cell cycle?
How do your wounds heal?
Is the given figure correct? Why?
Sketch and label the phase of cell division in which synaptonemal complex is formed?
What is disjunction?
Why mitosis and meiosis – II are called as homotypic division?
Is the meiosis responsible for evolution? Justify your answer.
What happens during diakinesis?
Why meiosis is important?
Diagrammatically differentiate between cytokinesis in animal cell and plant cell.
What would have happened in absence of meiosis?
Elaborate the process of recombination.
With the help of suitable diagram, describe the cell cycle.
Write the significance of mitosis.
Students were observing a film on Paramoecium. It underwent a process of reproduction. Teacher said it is due to cell division. But students objected and said that there was no disappearance of nuclear membrane and no spindle formation, how can it be cell division? Can you clarify?
Some cells do not have gap phase in their cell cycle whereas some cells spend maximum part of their life in gap phase. Search for such cells. Some cells are said to be in $G0$ phase. What is this $G0$ phase?
