Question

What type of placentation can be seen in sweet pea?

Answer 1

Placentation:

1. Placentation is the arrangement of the placenta inside the ovary of a flower.
2. The placenta is responsible for connecting the ovules with the ovary's wall.
3. Types of placentation are: marginal placentation, parietal placentation, axial placentation, basal placentation and free central placentation.

Placentation in sweet pea:

1. Sweet pea shows marginal placentation.
2. In marginal placentation, a ridge is formed by the placenta along the ventral suture of the ovary.
3. The development of ovules takes place on the ridge.
4. Thus, two separate rows are formed.
