Biology

Brilliant_brown [7]3 years ago

Louis Pasteur’s experiments has taken a leap on cell biology. He was able to contribute to the concept of cell theory which suggests that cells came from pre-existing cells, cells are the fundamental unit of life and that all life have cells.

Highlighting on pre-existing cells, early before the experiments of Pasteur, there was the theory of spontaneous generation. This theory claims that organisms came from nonliving objects which is now, truly misleading and wrong.

contrast the chromosome number in gametes and zygotes in sexual reproduction into your answer in the space provided
Mandarinka [93]

Answer:

Chromosome number in gametes- haploid (n)

Chromosome number in zygote- diploid (2n)

Explanation:

Sexually-reproducing organisms make use of gametes to reproduce. The gametes are produced via the process of meiosis, which is a cell division that results in daughter cells (gametes) that have their chromosomal number reduced by half. A diploid (2n) organism i.e. possess two set of chromosomes undergoes meiosis to produce haploid (n) gametes i.e. contains one set of chromosomes. The male parent produces haploid sperm while the female parent produces haploid egg.

During reproduction, these haploid gametes (sperm and egg) combine in a process called FERTILIZATION to produce a diploid ZYGOTE. The diploid zygote then divides and grows into the full organism. Hence, since a zygote is formed by the fusion of two haploid gametes (sperm and egg), it contains a diploid chromosome number i.e. sperm (n) + egg (n) = zygote (2n)
