AI Thread Summary
In trees undergoing secondary growth, the increase in girth can lead to the splitting or shedding of various tissues, particularly the outer bark and certain layers of the cambium. The affected tissues include the periderm, which is the protective outer layer, and the phloem, responsible for nutrient transport. When these tissues are lost, the tree can replace them through continued growth of the cambium, which generates new layers of phloem and xylem. The discussion emphasizes the importance of understanding tree trunk structure, including the roles of different tissues, to address the question effectively. Participants encourage providing a preliminary answer to facilitate further assistance, suggesting a focus on the biological aspects of tree growth and tissue functions.

In a tree undergoing secondary growth, many of the tissues will split or even be shed, due to the increase in girth of the stem. Which tissues will be affected in this way? It they are lost, how will replacements be made?

Could anyone please help me with this question? Thank you.

You need to provide us with your attempt at an answer before we can help.
 
This appears to be a homework question. Quy Perhaps you may want to post this in the biology section for homework. (listed as Other Sciences under Homework) There are many qualified folks there, who will be pleased to assist you. As Dave mentioned, you also will need to make a reasonable attempt to try and answer your question before helpers will assist you.

Here is one way you might start. Describe what do you know about the structure of a living tree trunk. Can you name the different tissues and their function? Which of these tissues do you think may be affected (in your question)?

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
