Fertilization in pollen grains is the process by which a pollen grain attaches itself to the stigma of a female flower, releasing its male gamete (sperm cell) which then travels down the female flower’s style to the ovary and fertilizes the egg. This process is critical to the reproductive cycle of flowering plants and is …
What is the change that happens to the pollen rain after fertilization ? After fertilization, the pollen rain changes from free-floating pollen grains to pollinia, which are masses of pollen grains held together by a protein-based adhesive. Pollinia are more efficient at transferring pollen to the stigma of the target flower. fertilization,pollen rain

Hydra-budding is a form of asexual reproduction used by certain species of Hydra. It occurs when an individual hydra produces buds that eventually break off and become new, independent individuals. These buds are typically formed at the ends of the body and contain all the necessary components to form a new organism. This process allows …
Fungus spores are the reproductive cells of fungi, which are microscopic and spread easily through the air. Spore formation is a way for fungi to reproduce and spread to new areas. Fungal spores are formed through a variety of processes, including fragmentation, budding, and sexual reproduction. Spore formation is triggered by environmental factors such as …
Bacteria binary fission is a type of asexual reproduction that involves a single parent organism splitting into two daughter cells. During binary fission, the bacterium’s single circular chromosome is replicated, and the two copies are attached to different parts of the cell membrane. The cell then elongates and eventually splits into two daughter cells, each …
