You are the best teacher.A teacher is not good because he has high degree enough knowledge but a teacher is good on the basis that how much a student learn . Thanks sir a lot. If you are agree than like👌👌

Vipin Just to ease the concept : At 20:18 onwards you are talking about the early and late wood, and their density. But it would be more easy to understand if you add little physics. Density = Mass/Volume. In spring and summer the rate of plants grow increases. In such condition the demand for photosynthesis also increases, as you already know that photolysis of water is essential so huge quantity of water is transported which is favoured by transpiration. So transport huge quantity of water the volume of the vessels and tracheids also increases, but they are thin (low in mass). Therefore by the formula of Density = Mass /Volume; if denominator increases than numerator the value goes down. And therefore the xylem formed during spring has low density. Things happens opposite during autum as the leaf sheds and rate of transpiration goes down, water transportation also goes down. Therefore there is no need for xylem with higher volume but need xylem to bare the weight and support the growing tree, so mass of xylem is higher creating a high density wood. Hope this will help. 😊
You are doing such an amazing job by helping students all over India, these videos are so much better than going to institutes like AAKASH in Tamil Nadu.(The north Branches of Aakash are good, I hear) But state board students of TAMIL NADU jinke syllabus,NCERT ke aas pass bhi nahi hai, you are a BOON to them :) Thank You Vipin Sir! Actually I SALUTE you!!! ~ AN EVER GREATFUL STUDENT from Chennai!
