can anybody here give me some idea about errera's law ?it's related to anatomy of angiosperm.?

Question

anatomy of angiosperm

Answer 1

Why Trees Defy Errera's Law


Science is very careful in naming laws as tributes for their discoverers, and those recognitions are expected to be permanent ones since the physical sciences and mathematics believe their laws will be absolute and unyielding.
Conjectures and hypotheses need not apply.

The laws of biological science have softer textures, however, since the creatures they cover are the embodiment of self-selected dynamics and change.

A hundred million year's previous use of some operational method for a life form may further advance or simply disappear tomorrow, and new workable accommodations of chemistry and physics will be the core of the next evolution. Life too, has its laws, but they have the inescapable caveat that nature may change them anytime she desires.

IMPORTANT FOR YOU--

Errera's law (1888) holds that the divisional plane of a cell will take place along the smallest surface area. This is explained as an economy of time, material and energy that all cells follow. It is not Errera's conjecture or Errera's theorem; we find it in the literature as a law.

In Growth Patterns in Vascular Plants and The Vascular Cambium, on the cambium of trees, both Iqbal and Larson as respective authors, state that cambial cells "violate" or" do not conform to Errera's law." Neither text, however, asks the question, "Why?"

To answer that question, the author steps from an illustration in a children¹s science book, through cambial anatomy and cytobiology, including an examination of Aeschynomene hispida as an example of periclinal and anticlinal divisions that occur exclusively along the maximum plane or surface area.

The explanation is both fascinating and provocative: Cambial cells ignore Errera's law to operate under other laws that better serve the broader biological designs of the cambium rather than a singular issue of cellular efficiency.

I grew up in a very small town and High School was were all the activity was except for getting drunk and making out. I even did some of that at school. LOL It's hard to believe I survived High School and I was an "A" Student. School is were Girls were and were I played Football so I had a blast. It didn't hurt that by the time I started High school my Dad had quit drinking (He was one of the worst alcoholics I have ever seen) . Mom was still a pain but Dad and I became best friends, So I guess my view of my High school years is a little biased. The School Dances were big events in a small town that had one movie theater with just one screen, no fast food restaurants and no malls. We didn't get Rock Concerts coming within 150 miles so I didn't see my first Live Concert until I went away to college unless you count local bands playing at the Dances.
