Main topics covered in this lecture: 0:50 - What is phloem? 3:09 - What are the components of phloem? 4:15 - What are sieve elements? 4:22 - Sieve tube members 7:20 - Sieve cells 8:29 - Companion cells 9:49 - Phloem parenchyma 12:37 - Phloem fibres 13:50 - Protophloem and metaphloem
If you remove the bark the xylem is free and not protected and phloem is gone, so in this section, there will be no food transport, but is it possible for Xylem/Parenchyma to differentiate into a cambium to form new Phloem cells? like secondary meristem?
You are the first to give me an answer for this question. I am very happy about that. Actually the answer depends on the age of the tree. If the tree is really old, girdling at the base of the tree, will kill the tree. But if the plant is young and actively growing it will manage to regrow the bark. I myself tried it (just out of curiosity ;)) in some of my experimental plants. They were three-month old Populus sp. plants and I saw that the plants managed to regrow bark after a few weeks and grew normally thereafter. Keep it up the spirit of learning. I really appreciate it. Best regards, Shanty
The tree will continue living because the ring is just at the superficial layer of the stem and so food and water transport will not be affected Thanks for your nice lecturer 👍🙏
Thank you for your attempt to answer the question. If we remove the bark (phloem), conduction of food will be affected. If the tree is an old one as shown in the lecture, it will eventually die. On the other hand, if the tree is young, it will slowly regenerate new bark and may survive. Best regards, Shanty
My dear Sister brother This content is very useful fr my degree second semester.. Very easy to understanding.. The each and every point of this content ... Tq very much sis......
Your explanation was sooooooo good mam I also had a seminar on complex tissue and I had watched your thus video and had given this type seminar really mam so helpful this video thanku sooooooooo soooooooo much mam
Hi Hemanth, since the tree is old it will not survive for that long. But if it was a young tree it may produce new phloem cells and may survive. Thank you for attempting and I really appreciate that. Best regards, Shanty
Mam, l think...the tree will survive because..we have cut only the bark not the Vascular Cambium...and so, the Cambium will produce the Phloem quickly...to transport food....
When you remove the bark, the vascular cambium will also rupture because the cambial cells are thin walled. If you peel off a strip of bark around the entire diameter of a tree, as in the case of this old tree, the roots will starve and the tree will eventually die. Best regards, Shanty
That's a brilliant question but the reason is unclear. It could be that phloem parenchyma helps in food storage and in monocots this function is performed by water cavities. Best regards, Shanty
Very g0od lecture Ma'am.. Nd i think tree will survive because u r rem0ving periderm 0r bark nd that is dead nd it c0ncern ab0ut the pr0tecti0n n0t ab0ut f0od c0nducti0n nd f0od c0nducti0n remain c0ntinue .
Hi Shazia, thanks a lot for sharing your opinion. However, if we remove the bark (phloem), conduction of food will be affected. If the tree is an old one as shown in the lecture, it will eventually die. On the other hand, if the tree is young, it will slowly regenerate new bark and may survive. Best regards, Shanty
Dear Priyanka , the answer is plant roots will die first due to lack of food . Since phloem is removed through gridding so no conduct of food in root possible. As Xylem is still their , conduction of water will not stop . Leaf can perform photosynthesis . But in long run plant will die .
Thanks again mam............. Mam can u try to make vedio on Phellem Phellogen Phelloderm......So confusing topic secondary growth in dicot root stem next vedio plz....
Hi Pranav, I will surely upload that video but I am uploading according to the topics in the NCERT text, otherwise many students may not be able to follow it. Best regards, Shanty
hello mam. hope you are doing well.you are doing a great job . mam kindly tell me the answer of the question you asked at the end of the video . love your work and lectures .May God bless you a lot with lots of success ,health and prosperity ameen
Because girdling the tree removes its outer bark and disrupts the phloem, the sap, or food, produced by the leaves cannot reach other parts of the tree. The tree slowly dies due to lack of nutrients and moisture. It may take up to one year for the tree to die.
Wow! That's right. Also if the tree is young most probably it will regenerate new tissue and may grow normally. I really appreciate the way of answering..really amazing. Best regards, Shanty
Really! i also want to become one but everyone tells to become doctors except my parents(they understand me),mam you should also make vedio on how interesting it to be a botanist. thankyou for making me so happy today, hope one day i will be like you
Thank you for sharing your problem with me. In my case, after my higher secondary education, I was very sure that I had a strong passion towards Botany. Plants and nature never cease to amaze me :) So I made up my mind to choose the subject that I loved and I chose B.Sc. Botany and Plant Biotechnology. Always follow your passion and aim the stars in the sky ;). It is not important what you learn, but it is important how you learn it (enjoyed or not). It is not important what you do, but it is important how you do your job. I know that many students face similar problems from the societies. If I get time I will make some videos to raise awareness among people to treat all subjects and professions with equal respect. Best regards, Shanty
Thankyou so much mam for motivating me, i become really very depressed when people talk that there is no scope in other fields except medical (i personally respect doctors a lot). even they always compare you with your mask (means you cant be a scientist if you are average in studies) 😓. but once again thankyou for inspiring me ,i will definitely follow my heart😊😊😊, thankyou
Actually, there is no 'magic subject' with a lot of scope for a job. If you can excel in the field you choose, then success will follow you. So select a subject which you like the most and reach to the top. Wish you all success. Best regards, Shanty
The phloem fibres will be cut out this stops translocation the plan will survive but only till the reserves in the lower part of the trunk support formation and development of root eventually since no new glucose reach the roots the apical meristems in roots die and then good bye tree. But why take the risk and kill the tree I don’t understand humans .hehehehe
Main topics covered in this lecture:
0:50 - What is phloem?
3:09 - What are the components of phloem?
4:15 - What are sieve elements?
4:22 - Sieve tube members
7:20 - Sieve cells
8:29 - Companion cells
9:49 - Phloem parenchyma
12:37 - Phloem fibres
13:50 - Protophloem and metaphloem
Mam their will be no any effect in food transportation as phloem is present at inner part of the bark of the tree. Hence the tree will survive
You are born to be a Teacher.........Respect from Pakistan.................
Thanks a lot Yousaf. Best regards, Shanty
May god bless you
The lecture was made easy and simple to understand 🥰
You are helping many student across the world
THANK YOU MAAM 💐

Mam the rate of videos uploading are very slow and I don't think you would complete the course of biology class 11.
Yes the tree will survive because pholem transport food in bidirectional so tree can Survive I think please answer my comment as early
Hi Hemanth, since the tree is old it will not survive for that long. But if it was a young tree it may produce new phloem cells and may survive. Thank you for attempting and I really appreciate that. Best regards, Shanty

Answer is tree dies because it would not be able to make more new cells. as the tree is mature. Thanks ma'am for the video.
That's right Tanvi. The food transport in the tree will be disrupted and the tree will eventually die. Best regards, Shanty
Thank you madam ....Iam open school student...iam understand very easy now.....my aim become doctor...

Great job! Mam! But can you please clear my doubt about that why phloem parenchyma is absent in monocot??
That's a brilliant question but the reason is unclear. It could be that phloem parenchyma helps in food storage and in monocots this function is performed by water cavities. Best regards, Shanty
If the plant is a young plant then it will survive and if it is old plant then it may or may not survive
