Question

Gynoecium is made up of
a. Stigma
b. Style
c. Ovary
d. All of these

Answer 1

Hint: the female part of a flower, consisting of one or more carpels is known as gynoecium.
Gynoecium is the female reproductive organ of a plant. It holds an ovary, which is transformed into fruit after fertilization. The ovules within the ovary are modified into seeds.
If carpels are free the gynoecium is known as apocarpous
If carpels are united the gynoecium is known as syncarpous.
Gynoecium consists of a female reproductive unit known as carpels.
Gynoecium is made up of three parts namely stigma, style, ovary.

Complete answer:

> STIGMA: - the stigma is very important to the process of reproduction in flowering plants. It provides a receptacle for pollen to land on and be rehydrated before entering the style to travel to the ovary. Without stigmas, flowering plants would not exist. So, this option is correct

> STYLE: - The style is a hollow tube in some plants such as lilies, or has transmitting tissue through which the pollen tubes grow. So, this option is also correct.

> OVARY: - The ovary, is the enlarged basal portion which contains placentas, ridges of tissue bearing one or more ovules. So, this option is also correct

> ALL OF THESE: - As above stated all the options are correct. So, they all are correct
Our correct option is d that is all of these as three of the parts are present in gynoecium.

Note: Gynoecium is the female reproductive part of the flower and is made up of one or more carpels. A carpel consists of three parts namely stigma, style, ovary. Each ovary bears one or more ovules attached to a flattened, cushion like placenta.
The arrangement of ovules within the ovary is known as placentation.
