Sieve Analysis and Grading Curves

Sieve Analysis and Grading Curves

Sieve analysis is a method used to determine the particle size distribution of aggregate materials. This process involves the following steps:

Diversity of Protists IV

Diversity of Protists IV

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Problem of sieve-tube slime.

Science (New York, N.Y.)

|April 19, 1968

Summary

A living, filamentous reticulum within sieve tubes may block pores in old sieve plates. This structure persists throughout the plant

Area of Science:

Plant Biology
Plant Physiology
Cell Biology

Background:

Sieve tubes are the primary conduits for long-distance transport of photoassimilates in plants.
The structural integrity and function of sieve tubes are crucial for plant survival and development.
Previous understanding of sieve tube contents and their role in maintaining function was incomplete.

Purpose of the Study:

To propose the existence of a stationary, living, filamentous reticulum within functioning sieve tubes.
To elucidate the role of this reticulum in sieve plate maintenance and pore blockage.
To describe the characteristics and behavior of the filamentous reticulum and associated slime.

Main Methods:

Microscopic observation of sieve tube elements.

Analysis of filament diameter and structure (striations).

Investigation of slime binding and hydrolysis within sieve tubes across different species.

Main Results:

A stationary, living, filamentous reticulum (100-150 angstroms in diameter, often striated) is proposed to exist in sieve tubes.
Filament swelling is suggested as a mechanism to block pores in aged sieve plates after slime loss.
Slime association with filaments varies: loosely bound in Cucurbita, hydrolyzed and metabolized in other species.

Conclusions:

The filamentous reticulum is a persistent, integral component of functioning sieve tubes.
This reticulum plays a vital role in the structural maintenance and functional regulation of sieve plates.
Understanding this structure provides new insights into phloem transport and sieve tube longevity.
