What are the key characteristics of haploid eukaryotes and how do they differ from diploid eukaryotes?
Haploid eukaryotes have one set of chromosomes, while diploid eukaryotes have two sets. This means haploid cells have half the genetic material of diploid cells. Haploid eukaryotes are typically found in reproductive cells, like sperm and eggs, while diploid eukaryotes are found in most other cells of the body.

Chromosome number that results from meiosis is called?
Meiosis reduces the number of chromosome sets from two (diploid), to one (haploid). In mitosis the daughter cells are genetically identical to the parent cell, but meiosis produces cells that differ genetically from the parent cell as well as each other. In the final stage of meiosis II there end up being 4n daughter cells. So remember mitosis is diploid and meiosis is haploid.
In what ways do eukaryotes and prokaryotes differ from each other?
Eukaryotes have a nucleus and other membrane-bound organelles, while prokaryotes do not. Eukaryotes are typically larger and more complex than prokaryotes.
Does sexual life cycles differ with respect to the relative timing of meiosis and fertilization?
Yes, sexual life cycles can differ based on the relative timing of meiosis and fertilization. In some organisms, such as animals, meiosis and fertilization occur separately and alternately, resulting in a diploid-dominant life cycle. In contrast, in some algae and fungi, meiosis and fertilization can occur in close succession, leading to a haploid-dominant life cycle.
In what way are mature sperm and egg cell different from all other types of body cells?
Gametogenesis is the production of gametesGametogenesis differ between females and malesSperm become streamlined and motileSperm primarily contribute DAN to an embryoEggs contribute DNA, cytoplasm, and organelles to an embryoDuring meiosis, the egg gets most of the contents; the other cells form polar bodies
How does the daughter cells produced from meiosis differ from those produced by mitosis?
What I remember from school was that meiosis split into 4 cells and that mitosis split into two cells and I think that meiosis happened when cells were trying to repair something and mitosis was for reproduction. (Remember miTosis=Two)
How do haploid cells differ from diploid cells?
Haploid cells only have half the necessary amount of DNA (sex cells). Diploid cells have a full set of DNA (body cells).
How does the chromosome number in a diploid cell differ from the chromosome number in a haploid cell?
A diploid cell contains two sets of chromosomes, one from each parent, while a haploid cell contains only one set of chromosomes. In humans, a diploid cell has 46 chromosomes (23 pairs), whereas a haploid cell has 23 chromosomes.
Why is pollen a diploid?
Not sure what level you're asking this on; pollen is not really haploid (it has several cells). Anyway, here goes: In normal sexual reproduction, half of each parents' DNA combines to form a new genetic code. A haploid cell has half the number of chromosomes contained in a diploid (normal) cell. This means that the offspring are a mixture of the characteristics of the parent organisms, creating variety within the population. If pollen was not haploid, it could not provide genetic material capable of binding to the ovum's genes. Pollen actually contains 3 haploid cells; so a pollen grain is not a single cell. When it meets the stamen of another plant, one cell forms a tube going down to the ova, acting as a sort of navigation system, while 2 of the cells follow. It was at this point that this mornings genetics lecture ended, so to find out what happens next, I'll have to wait until next Monday. Hope some of that was useful :)

How are protists and plants similar and how they differ?
They are Eukaryotes
How are daughter cell differ from the parent cell?
The parent cell will be diploid and contain paired chromosomes. The haploid cell will contain only one copy of each chromosome. In humans for example there are 23 pairs of chromosomes. In a somatic cell, which is diploid, the 23 pairs are present. In a gamete (sperm or egg cell), which is haploid there are only 23 chromosomes - unpaired. This is so that when the sperm and egg meet at fertilisation there are 46 chromosomes - 23 pairs - the correct number for the organism.
How do the cells of the bacteria differ from those of eukaryotes?
Bacteria are prokaryotes.
Why are eukaryote and prokaryote cells differ?
Eukaryotes have a nucleus. Prokaryotes do not have a nucleus.
What are the cells called that have a nucleus and organelles?
There are two basic types of cells, prokaryotes and eukaryotes. Eukaryotes differ from prokaryotes in a few ways, but the biggest difference is that eukaryotes have a nucleus and prokaryotes don't.
In what ways do eukaryotes and prokaryotes differ from each other?
Eukaryotes have a nucleus and other membrane-bound organelles, while prokaryotes do not. Eukaryotes are typically larger and more complex than prokaryotes.
How many chromosomes does fungi have?
There are over 200,000 species of fungus, including moulds, mushrooms, yeasts and lichens. They have different chromosome numbers, the number may even vary with the same species as well as the type of reproduction they are under going (vegetative or sexual)
How does the location of the electon transport chain differ in eukaryotes and prokaryotes?
In eukaryotes it is located in the organelle called the mitochondria. In prokaryotes it is located in the cellular membrane.
