Question

What is the major difference between
1) transpiration and guttation.
2) leptotene and zygotene

Answer 1

2) Leptotene and Zygotene both are the parts of Prophase-I in meiosis.

Leptotene :- In leptotene choromosomes are condensed and the appear like thread. Chrosomal end face towards nucleolus and centrioles duplicates and moves toward opposite pole of the cell.

Zygotone :- Two homologous chromosomes come in contact (one maternal and one paternal chromosome) and form a pair of chromosome called as 'Synpasis'.

Answer 2

Answer:

Leptotene-

- Condensation and coiling of

Chromatin fibres begins during

Leptotene and Chromosomes are

formed, which are visible under

the light microscope.

Bouquet formation( telomeres of

the chromosomes get polarized

towards the centrioles)
