For a introduced species to be invasive species, there needs to be certain characteristics of the species.
<h3><u>Explanation</u>:</h3>
Invasive species are the species that belong to some other place and are introduced to a new place by means of any human interference. But many species are often transferred from one place to another. But not all of them remain there as an invasive species. This is because for being an invasive species, they need to have certain characteristics:
A. They need to have high rate of reproduction.
B. They need to have short dormancy periods.
C. They need to have high generic variability.
D. They need to be polyphagous and gregarious.
E. They need to have high dispersal rate and great adaptability.
F. They need to have phenotypic plasticity.

<em>sieve tube elements are the cells of phloem which allow transportation of photosynthates through phloem...
<u>
how sieve tube elements form sieve tubes:
</u>sieve tube elements are connected end to end and form a long chain which is called sieve tube,,,,
sieve tube elements are connected with the help of a side chain with the help of peptide bond...also one element has tapering end which easily overlaps with other end of next element to form sieve tube,,,,</em>
