Are diploid cells formed when a sperm fertilizes an egg? How does fertilization occur in flowering plants? Are gametes sex cells or zygotes? What happens in human fertilization? What begins with a haploid cell? What is the difference between a blastocyst and an embryo?
What is meiotic drive? How spindle fibers are formed in plants? Which offspring of a single-celled eukaryote would inherit a mutation acquired by the parent cell? Why do prokaryotes need to have genetic variation? How do genetic clones provide evidence that differences between cells are the resul...
roses, fuchsias and daisies; the group also contains allgrasses, and most well-knowntrees(apart from those that produce cones). Birch, beech, ash and willow trees, for example, are all flowering plants, as is the Johnson grass in the photo below. ...
Well, cell cycle has two ways about it. First is Mitosis and the second is Meiosis. Mitosis is what gets us from a zygote to a full-grown adult while meiosis makes gametes or sex cell, i.e. sperm and egg. Recommended Video for you: Play How Do Plants Reproduce? Cell Cycle: Interpha...
3.Formation of the Endosperm in a Fertilized Ovule: - During fertilization in flowering plants, two key events occur: - One male gamete (sperm cell) fuses with the egg cell to form thezygote(diploid). - The second male gamete fuses with the two polar nuclei located in the central cell ...
The transfer of pollen from the anther to the stigma of a flower is called pollination. During fertilization, the male and female germ cells of the pollen unite to form azygote. A zygote then transforms into an embryo, which eventually becomes a seed. The seed then germinates into a new ...
The primary root meristem is formed during embryogenesis and supports the first growth of the seedling into the soil. However, the continuous growth of the above-ground plant parts imposes the establishment of an elaborate root system in order to mine for additional water and nutrients. This can...
How haploid gametes (sperm and egg cells) combine to form adiploid zygotewith two sets of chromosomes. Are gametes haploid or diploid in plants? Unlike animals(see Chapter 2), plants havemulticellular haploid and multicellular diploid stagesin their life cycle. Gametes develop in the multicellular...
Step-by-Step Solution:1. Definition of Zygote Intra-Fallopian Transfer (ZIFT): - ZIFT is a reproductive technology where a zygote or an early embryo is transferred into the fallopian tube of a female. This t
by a change in the way divisions are controlled. The triggers and mechanisms of mitotic cell division have been studied in detail in Arabidopsis and other flowering plants (Gutierrez2016), and it will be interesting to see how these differ between land plant embryos and algal zygotes. However...
