In groundnut, seeds are_______.
A. Geocarpic
B. Amphicarpic.
C. Photocarpic
D. Epicarpic.
Solution
Seeds are embryonic plants that are enclosed by the protective outer covering. This formation involves the process of reproduction. As we have already learnt in our junior classes, seeds are classified into different categories based on fruits and plants. Here, it can be found based on the seed morphology.
Complete answer:
Apios americana(groundnut) is a perennial vine which bears large edible tubers and edible beans. This can grow 1-6 m long. It can also be called as American groundnut, hodoimo, Indian potato.
The following are the classification, name, kingdom, family for the groundnut. They are as follows:
| HIGHER CLASSIFICATION | Apios |
|---|---|
| SCIENTIFIC NAME | Apios americana |
| KINGDOM | Plant |
| FAMILY | Fabaceae |
| ORDER | Fabales |
| BIOLOGICAL RANK | Species |
Here, we are going to see the geocarpic, amphicarpic, epicarpic seeds.
GEOCARPIC SEEDS:
It is an extremely rare means of plant production in which they produce diaspores within the soil.
It means producing or ripening the fruit beneath the surface.
This has evolved as an effective means of environment.
AMPHICARPIC SEEDS(AMPHI- both of the kinds and CARPIC- fruits):
It means producing both kinds of fruit either to form or ripening.
It is a reproductive strategy that occurs with 13 plant families.
It is expressed mostly in species with an annual lifecycle.
EPICARPIC SEEDS (EPI- on/upon and CARPIC- fruit)
The outermost layer for pericarp as a rind or peel of certain fruits.
It forms the tough outer skin of fruit.
It is sometimes called an exocarp.
From the above definitions, it is clear that the correct answer is Option A.
ADDITIONAL INFORMATION:
Geocarpic seed is most frequent in tropical or semi desert areas.
These plants bend their stems so that it can be embedded in the soil.
It is also linked with solifluction soils.
These are more prevalent in the high altitudes of east Africa.
Note:
Geocarpy is an extremely rare means of plant that produces diaspores in the soil. This may occur in proto geography or from hysteroscopy. This has evolved as an effective means of environment for plant offspring.
