SOVA2 [1]3 years ago

<span>Homologous chromosomes have to attach together to the same spindle fiber during prophase 1. Then, some of them may go through crossing over, which switches fragments of them. Then, each pair of homologous will migrate to equatorial plane during metaphase 1. So, in the metaphase plate you will have pairs of homologous, both of them duplicated, but the 4 chromatides may be different due to crossing over (it depends on where the enzymes have cut and pasted in that process).</span>

Explain how structure of cell wall in xylem tissue enables it to be strong and flexible?
Drupady [299]
The walls of xylem cells are lignified (strengthened with a substance called lignin ). This allows the xylem to withstand pressure changes as water moves through the plant.

The cell membrane is flexible because of the presence of oil like substances called phospholipids, which gives it a fluid nature. While as the cell walls are rigid because of the presence of the thick layers of the substances like cellulose in plants, chitin in fungi and peptidoglycon in bacteria.
