The process must occur before the gametophyte generation is Sporophyte. A sporophyte is the diploid generation of a plant or alga that has a double set of chromosomes. [ All land plants, and some algae, have life cycles in which a multicellular haploid gametophyte generation alternates with a multicellular diploid generation. In the Gymnosperms and flowering plants (Angiosperms), the sporophyte generation is the most prominent phase, comprising the familiar green plant with its roots, stem, leaves and cones or flowers. In the flowering plants, the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.

Why is the nucleus so important to a living cell?

Shalnov [3]

The nucleus is important to a living cell because it serves the function of information storage, retrieval and duplication of genetic information. It is a double membrane‐bound organelle that harbours the genetic material in the form of chromatin.

During dna replication, a thymine base is removed from the dna. what type of mutation is this? apex

polet [3.4K]

I believe this is an example of frameshift mutation.
Frame shift mutation is a type of mutation that is caused by addition or deletion of a base pair or base pairs in the DNA of a gene resulting in the translation of the genetic code in an unnatural reading frame from the position the position of the mutation to the end of the gene.

Ksivusya [100]

Answer:

Explanation:

A carp (a kind of fish) has 104 and a rattlesnake fern has 184. Most likely neither of these is as complicated as we are (especially the fern).

These kinds of differences are out there because the number of chromosomes doesn’t have anything to do with how complicated or “advanced” a living thing is. What matters is what is on them.

Your fewer chromosomes have the set of instructions for making you and a potato’s chromosomes have the set of instructions for making a potato plant. It doesn’t matter how many pieces those instructions are cut up into.

Think about it like comparing the instructions for building a car to the instructions for building a bicycle.

Let’s say the car’s instructions are in one big book but the bicycle’s instructions are spread over five books. Making a bicycle isn’t more complicated than a car just because it is in five books instead of one. Same thing with your chromosomes and a potato’s chromosomes.

It also doesn’t always have to do with how many “pages” or even sets of instructions are in something’s chromosomes.
