Andrei [34K]

Answer:The Cycad tree is the sporophyte.They have flagellated sperm.

Explanation:

During pollination, the contents of the megaspore divide to form many–celled gamateophyte called the endosperm and archegonium. There is a micropyle opening with a sticky fluid, which traps the wind-borne male gametophyte (microspores) which,at this time is made up of prothallus cell;an antheridial cell and a large tube cell. The trapped microspore is sucked into the archegonia chamber. Antherizoids are released, but only one penetrates each oospore and fuses with the female nucleus. The zygote is formed in the ovule and the later develops into seed.The diploid seed germinates into a new sporophyte plant and the life cycle begins again. Examples of cycad include Cycas circinalis ,Cycas celebrical and Cycas revoluta

Myrmecia pilosula was originally described as a single species, however, after closer examination, it was determined to consists
JulijaS [17]

Answer:

The correct answer is "34".

Explanation:

The ant Myrmecia pilosula is a special case of sexual reproduction, where the females produce gamete cells with half the chromosomes of the somatic cells and the males are haploids that transmit the whole number of chromosomes in their gametes. Therefore, the somatic cells of the hybrid female offspring that results from the cross of a female ant with 48 chromosomes and a male with 10 chromosomes would have 34 chromosomes. This result from half the number of chromosomes of the female (24) plus the total number of chromosomes of the male (10).
