Answer:
A small GTP-binding protein called dynamin assembles as a ring around the neck of each deeply invaginated coated pit, pinch off the vesicle. After the budding is complete, the coat proteins are removed, and the naked vesicle can fuse with its target membrane.
Explanation:
Dynamin - may be a GTPase that takes part in an important role in clathrin-dependent endocytosis and other vesicular trafficking processes by acting like a couple of molecular scissors for newly setup vesicles originating from the cell wall.
Answer:
The correct answer is option - A. Gametophyte, C. spore, and D. sperm.
Explanation:
The egg cell of a plant is haploid in the cell which means it has only one set of chromosomes. The haploid cells arise from the meiosis cell division in parent sex cells. These parent cells are divided into four cells with half of the chromosome number in comparison to the parent cells.
The gametophyte, spore, and sperm all three are the product of the meiosis division and are haploid in number.
Thus, the correct answer is option - A, gametophyte, C. spore and D. sperm.
