Whiteboard picture ( 03rd October 2020 ) CUBE CHATSHAALA, We saw a series of photos of Mung seeds(Green Gram seeds) from soaking them in water till the germination ( study initiate by Mothers and Grandmother, CUBE Nature Mechanics group) we also discussed about the work that @917261910367 did on Mung seeds …@Nidhi please share your work in detail and what all improvement do you want to do in your next set up…
Three diagrams were drawn on the Whiteboard in order to understand what’s a SEED. Right side: Front view of seed… left side: egg cell in ovule which is fertilized by male reproductive cell. Mid: Chicken egg … @magpie @Mandar @Lydia @saswathy679 @drishtantmkawale and others can we have a story of these three diagrams…
Aaah this was interesting… After seeing photo’s of Mung seed(from first day of soaking green gram seeds in tap water till 6 days of their germination)…Many questions being asked like What’s s seed??. What’s is an Embryo of plant??.. Let’s fill the gaps that we discovered in yesterday’s discussion

Summary of discussion by Arunima
Mung bean (Vigna radiate) is a popular growing legume and is widely consumed in form of mung bean sprouts in Asian cuisine, and the growth cycle of mung bean is short, which enables us to conduct more repetitive experiments.

Recent studies have revealed that audible sound stimulation has a great potential to improve plant growth and the quality of products.

Similarly, if a sound wave is moving through a plant or plant seeds, then particles of plant or plant seeds will be displaced both rightward and leftward as the energy of the sound wave passes through them. The motion of the particles is parallel to the direction of the energy transport. We assume there are biological effects of audible sound field on plant growth and seed germination because of sound energy transport and the degree of the effect is dependent on sound frequency and sound intensity.


germination period of mung bean was reduced after audible sound treatments. Results are similar to those music effects on the germination of okra and zucchini seed reported by Creath and Schwartz. The mechanisms are still unknown till now, but there is a hypothesis that the sound treatment of mung bean seeds in aqueous media can result in an advanced hydration process, which might be an explanation for the reduction in the germination period of mung bean

Biological Effect of Audible Sound Control on Mung Bean (Vigna radiate) Sprout
Audible sound (20–20000 Hz) widely exists in natural world. However, the interaction between

Questions raised by Mandar @Mandar
What is seed? How confusing it is?

Is the whole seed is embryo?
Or A part of seed is embryo?

What is cotyledons and role of it?

When we try to connect with how seed is developed from fertilization of ovary and forming embryo there were many gaps in discussing
what is endosperm, double fertilization, embryo, how seed is formed after fertilization?
