Practical 10 - Scientific drawing of cells from prepred slides of developing anthers to show stages of meiosis Flashcards
What did we see this transaction of during this practical?
Lilium anther
Which section of lilium anther did we see under the microscope during this practical?
Transection
Draw and label a lilium ather’s transection at 10x magnification
(Check notes)
Where would we see meiosis occurring in the anther?
Pollen sac
What occurs in the pollen sac of the anther?
Meiosis
What magnification can we see meiosis occurring in the pollen sac of the anther?
40x
Why can we see meiosis occurring in the pollen sacs of the anther?
This is where pollen is produced
Where is pollen produced in the anther?
Pollen sac
How many pollen producing chambers does each anther of a flower contain?
4
What’s there a large number of (produced by mitosis) in the pollen sacs?
Diploid pollen mother cells
What does each pollen mother cell do in the pollen sac?
Divides by meiosis to give 4 haploid cells
What do the 4 haploid cells of anther do?
Separate from each other to become pollen grains
What separate form each other to form pollen grains?
Haploid cells produced by meiosis
When does the production of pollen grains take place in flower development?
In the early stage of flower development, usually when the flower is in the bud stage
What occurs in the bud stage of a flower?
Production of pollen grains
