Mention the function of the following:
1.Pollen grain
2.Pollen tube
3.Ovary
4.Ovule
Answers
Ans 1...Pollen Grain.
Pollen grains carry male reproductive cells (gametes) in a plant and are haploid microgametophytes. Their main function is in the transferring of the male gametes to their female counterparts (ovules – female reproductive cells) in the embryo sac. It thereby facilitates sexual reproduction to occur in the plant.
Ans 2...Pollen Tube.
The pollen tube (PT) is a unique and specialized structure in plants. Its sole purpose is to deliver sperm cells to the female gametophyte for double fertilization. Essentially, it is a thread–like structure spanning from the pollen shell toward the tip.
Ans 3...Ovary.
The ovaries are small, oval-shaped glands that are located on either side of the uterus. The ovaries produce eggs and hormones. Fallopian tubes: These are narrow tubes that are attached to the upper part of the uterus and serve as pathways for the ova (egg cells) to travel from the ovaries to the uterus.
Ans 4...Ovule.
The ovule is part of the makeup of the female reproductive organ in seed plants. It's the place where female reproductive cells are made and contained, and it is what eventually develops into a seed after fertilization, only for the seed to then ripen and produce a complete adult plant.
