Safety precautions, list factors in the experiment, hypothesis and theory behind the experiment
Answer:
Chromosomes that carry the same genes.
Explanation:
The concept of homologous chromosomes can be simply explained as two chromosomes that are carrying the same genes but not necessarily the same alleles. For example one of them may have the dominant curly hair gene and the other may have the recessive curly hair gene etc.
Diploid cells and haploid cells possess 2n and n number of chromosomes respectively. Even though haploid cells have half the number of chromosomes as diploid cells, they still contain homologous chromosomes as diploid cells.
Germs and reproductive cells such as eggs and sperm can be given as an example to haploid cells. All other cells in our bodies and also some viruses can be given as examples to diploid cells.
I hope this answer helps.
Answer: it grows a tube to travel down to the ovary
Explanation:
As a result of pollination, pollen grain lands on the sigma of the pistil or carpel. On the stigma pollen grain begins to germinate and grows a long pollen tube. The pollen tube grows longer and makes its way from the stigma, down the style and reaches to the ovary. Pollen tube carries two male gametes or sex cells. One male gamete fertilize the egg cell to produce zygote and the gamete fuses with polar nuclei to form primary endosperm cell.
