To determine:
To compare the uterus of an insect with the ovary of flowering of a flowering plant on the basis of similarity and differences as refer to figure 30.7 “The development of a eudicot plant embryo”, in the textbook.
Introduction:
The sexual reproduction in flowering plants is occurring by the meeting and fertilization of male and female gametes. Pollens are male gametes whereas the flower represents the female part of plant that contain carpel and below carpel ovary is present.
In sects sexual reproduction takes place by the fertilization in the uterus of female by the merger of sperm and egg. Egg is produced by the ovary of the female insects and sperm is produced by the sex cell of the male insects.
