Compare the characteristics of sperm and ova and complete the given table suitably. Characteristics Sperm Ovum Size Motility Morphology

The completed table showing the comparison between the sperm cell and the ovum is as follows: Characteristics Sperm Ovum Size The sperm is the smallest cell present in the body of human males. The ovum is the largest cell present in the body of a human female. It is very large compared to the sperm cell. Motility The sperm cell is motile, as it has a tail for propulsion. The sperm cell gets energy for movement from the mitochondria present in the middle piece. The ovum is a round non-motile cell. Morphology The sperm cell has three parts- the head, middle piece, and tail. The head contains the nucleus. The ovum is a round cell with a centrally placed nucleus. These are protective layers outside the cell membrane.

Complete the given table suitably. Part Function Endometrium Uterus Placenta Umbilical cord Amnion

The completed table showing the different parts of the female reproductive tract and their respective functions is as follows: Part Function Endometrium This layer of the uterus helps in the implantation of the embryo. Uterus This part helps in the complete development of the foetus attached to the endometrium wall. Part Function Placenta It provides the foetus with oxygen and nourishment and also helps in waste removal. Umbilical cord It carries the blood of the developing foetus back and forth to the placenta. It delivers nutrients and oxygen to the baby and removes the baby's waste products. Amnion The amniotic fluids inside the amnion prevent dehydration of the foetus and protect it from external shock.
