Once the zygote starts to grow, the ovary begins developing into a fruit and the ovules begin to form seeds. The outside wall of the ovary and pistil becomes the skin of the fruit, or in some cases like the apple and pear, there develops a fleshy and edible material outside the ovary...
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 ...
In flowering plants, how do the sperm cells develop? How can asexual reproduction in plants produce genetically identical offspring when meiosis occurs? Describe the process of fertilization in humans. What process occurs to form ...
What transport mechanism is used by the foveolar cell and why? Name some of the specialized tissues. What happens during differentiation to form a specialized cell? What are the basic functions of plant cell walls? How spindle fibers are formed in plants?
Step-by-Step Solution:1. Definition of Triple Fusion: - Triple fusion is a process in flowering plants where one male gamete nucleus fuses with two polar nuclei. This results in the fusion of three nuclei,
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...
A sperm cell is transported from the pollen grain into the embryo sac via the pollen tube. The egg is fertilized by the sperm cell. The resultingzygotedevelops into a plant embryo. A second sperm cell fuses with other nuclei present in the embryo sac to createendosperm. ...
The process repeats, creating rosettes or spheres containing as many as 50 cells in the lab. If this all sounds familiar, there’s a reason for it — animal embryos develop from zygotes in much the same way, and spherical choanoflagellate colonies look uncannily like early-stage animal ...
Zygotes of M. alaskensis were de-jellied by repeatedly passing them through a hand-pulled mouth pipet cut to slightly larger than the egg diameter. To prevent de-jellied eggs from sticking to plastic, Petri-dishes were coated with 1% BSA in FSW before adding eggs. For injection, de-jellied...
