Cypsela is dry,indehiscent,single seeded fruit develops from an unilocular,single ovulate inferior ovary of bicarpellary,syncarpous,gynoecium possessing basal placentation. The fruit wall developes from pericarp and thalamus and is thin and remains attached to the seed at one point,eg,Helianthus. Caryopsis are dry,indehiscent,small,single seeded fruit develop from unilocular,single ovuled,superior ovary of multicarpellary gynoecium. If differs from typical achens as their pericarp is completely fused with the seed coat or tests,eg,Poaceae. Cremocarp are bilocualr and two seeded schizocarpic fruits (small,dry) developed from inferior ovary of bicarpellary,syncarpous gynoecium possessing persistant stylopodium,eg,Apiaceae. Berry is a flesly,indehiscent,few to multiseeded fruit derived from multicarpellary syncarpous gynoecium. The fleshy pericarp of berry consists of epicarp,mesocarp and endocarp.

Explanation:
Cypsela:
- Cypsela is a type of dry, indehiscent fruit that is formed from a bicarpellary syncarpous inferior ovary.
- It is a single-seeded fruit that does not split open upon maturity.
Characteristics of Cypsela:
- Cypsela is a type of fruit found in the Asteraceae family, which includes plants like sunflowers and daisies.
- It is often mistaken for a seed due to its small size and hard outer covering.
- The cypsela is derived from the ovary of the flower and contains a single seed inside.
Formation of Cypsela:
- Cypsela is formed from a bicarpellary syncarpous inferior ovary, which means it originates from an ovary with two fused carpels that are located below the attachment of the other flower parts.
- After fertilization, the ovary develops into a cypsela with a hard outer covering.
Examples of Plants with Cypsela Fruit:
- Some common examples of plants that produce cypselas include dandelions, marigolds, and thistles.
- These plants belong to the Asteraceae family and are characterized by their composite flower heads.
Importance of Cypsela Fruit:
- Cypsela fruits play a role in seed dispersal for plants in the Asteraceae family.
- The hard outer covering protects the seed and aids in its dispersal by wind, water, or animals.
In conclusion, cypsela is a unique type of dry, indehiscent fruit that is formed from a bicarpellary syncarpous inferior ovary and plays an important role in the life cycle of plants in the Asteraceae family.
