Q.Grow seed in the deep tray on soil medium and study different stages of germination. Prepare powerpoint presentation with the help of pictures/photographs of the same.

Sow a few large seeds (bean, gram or pea) 2-3 cm deep in moist soil in a deep tray, keep the tray warm and watered, and photograph the same seedlings every day for about two weeks; the pictures then become the slides of the presentation, one stage per slide.

Suggested plan.

1. Set up - fill a deep tray (at least 10 cm of soil) with moist garden soil, sow 8-10 soaked seeds 2-3 cm deep and 5 cm apart, and keep the tray in indirect light, watering lightly every day.
2. Record daily - photograph the tray and one gently lifted seedling each day at the same time; note the date, the day number and any measurement (radicle length, shoot height).
3. Stages to capture - the swollen (imbibed) seed; the radicle breaking the seed coat; the root system branching; the hook of the hypocotyl (bean) or epicotyl (pea) pushing through the soil; the cotyledons above the soil (bean) or the plumule alone (pea); the first foliage leaves opening; the shrivelling cotyledons.
4. Slides - title; materials and method; one slide per stage with the photograph, the day number and a caption naming the parts (seed coat, radicle, hypocotyl, epicotyl, cotyledons, plumule); a graph of shoot height against day; a closing slide relating the stages to the phases of growth in this chapter (cell division, elongation, maturation).

The same sequence is described for the bean in the NCERT/CBSE Class 11 chapter on plant growth, so the presentation also serves CBSE students.
