What else can I help you with?
Is the sporophyte stage of a moss much larger than the gametophyte stage?
Ferns have a dominant sporophyte and a reduced gametophyte. As for moss, it depends on the type. If referring to mosses under the phylum Bryophyta (these are the nonvascular mosses) they have a dominant gametophyte. If referring to mosses under seedless vascular category, such as club mosses in the phylum Lycophyta, these plants have a dominant sporophyte and a reduced gametophyte.
What cell does the gametophyte generation 1n begin in each pine cone?
In the female pine cone, the gametophyte generation (1N) begins in the megasporangium. For males, it begins in the microsporangium.
List these in order from smallest to largest chromosome gene cell?
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
Why dont the sperm nuclei of the male gametophyte of flowering plants have flagella?
During pollination, the sperm of the male gametophyte are not flagellated because they generally do not move. They rely on the growth of a pollen tube to deliver them to the egg cell.
What is the surrounding membrane that consists of 8 nuclei called in the flowering female gametophyte?
it is a sporophyte
How many chromosomes does a jaguar have?
Jaguars have 38 chromosomes, which is the typical chromosome count for most cat species in the Felidae family.
What is the term for the haploid form of a plant?
Gametophyte
What is a Chromosome complement?
A chromosome complement refers to the total number and types of chromosomes present in an individual's cells. It is specific to each species and can vary among different organisms. This complement plays a crucial role in determining an individual's genetic makeup and characteristics.
How many different kind of sperm?
Two, sperm that has an X chromosome and sperm that has a Y chromosome, all things being normal all sperm have the same chromosome count.
2n number of chromosome in human?
Humans have a diploid count (2n) of 46 chromosomes. Knowing this, it is easy to figure out what the haploid count is by halfing 46. Therefore, the haploid number of chromosome (n) is 23 chromosomes.
Gametophyte and sporophyte?
Gametophyte-haploid Sporophyte-diploid
What is the dominant stage of liverworts?
The answer is gametophyte.
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
How is gametophyte of Marchantia sp differ from the gametophyte of Polytrichum sp?
hehehe
Can one get a chromosome count on dried blood?
It may be possible to extract genetic material from dried blood samples to obtain a chromosome count, but the quality and quantity of DNA may be compromised by the drying process. Specialized techniques and equipment are required for accurate chromosome analysis, and the results may be less reliable with dried blood compared to fresh samples.
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)
Do eggs have gametophyte or sporophyte?
Egg being a gamete develops inside gametophyte
