Corymb and Umbel are of related type.
Explanation:
Corymb and Umbel are two different types of inflorescences found in flowering plants. Inflorescence refers to the arrangement of flowers on the stem or branches of a plant. Different types of inflorescences exhibit specific characteristics and structures.
1. Corymb:
- A corymb is a type of determinate inflorescence where the flowers are arranged in such a way that the lower flowers have longer stalks than the upper ones.
- The main axis of the corymb is elongated with the central flower opening first, followed by the lateral flowers.
- The flowers in a corymb are at the same level and form a flat-topped or slightly convex structure.
- Examples of plants with corymb inflorescence include hawthorn (Crataegus) and yarrow (Achillea).
2. Umbel:
- An umbel is a type of indeterminate inflorescence where the flowers are arranged in such a way that they arise from a common point and have stalks of equal length, giving the appearance of an umbrella-like structure.
- The flowers in an umbel are at different levels, radiating from a central point.
- The central flower opens first, and the lateral flowers open successively.
- Examples of plants with umbel inflorescence include carrot (Daucus carota) and parsley (Petroselinum crispum).
Related Type:
Corymb and umbel are considered related types of inflorescences because they share certain similarities in their structure and arrangement of flowers. Both inflorescences have the main axis elongated, with the central flower opening first, followed by the lateral flowers. However, the main difference lies in the arrangement of the lateral flowers. In a corymb, the flowers are at the same level and form a flat-topped structure, whereas in an umbel, the flowers are at different levels, radiating from a central point.
In conclusion, corymb and umbel are related types of inflorescences, but they differ in the arrangement of lateral flowers. Understanding these different types of inflorescences helps in plant identification and classification.
