Question

Ovule is attached to the placenta by a stalk named as
A. Funicle
B. Petiole
C. Pedicel
D. Placenta

Answer 1

In plants, placenta is an organ that is formed for physiological exchanges between the fetus and mother.

Complete Answer:
- Ovule is the part of the female reproductive system in seed plants. It is the place where female reproductive cells are made.
- The ovule develops into the seed after fertilization. Ovules are present in the ovary .
- The ovule is made up of nucellus (nutritive tissue), integuments (tough outer protective layer) and the female gametophyte (part of the ovule that contain gamete producing organ).
1. Funicle - Funicle is the stalk that attaches an ovule with that of placenta in the ovary of flowering plants. Funicle attached to the ovule in the region is called a hilum. So, hilum is the junction between the ovule and funicle.
2. Petiole – In plants, petiole is a slender structure that attaches the leaves of plant with that of stem or branch of plant. Petiole makes the leaves to twist or move.
3. Pedicel – Pedicel is the structure that connects a single flower to its inflorescence. In the absence of the pedicel, the flower is called a sessile.
4. Placenta – It is an organ that is formed by the fusion of maternal and fetal tissue. It provides the attachment between the ovary and ovules in plants.

Hence, option A is the right answer for this question.

Note: In mammals placenta is an organ that is formed on the inner side of the uterus of a female during fertilization. Placenta provides the exchange of gases, food between the mother and fetus. Places get shedded off after the birth of the baby.
