The correct Answer is:
To solve the matching question, we will go through each item in Column A and find the corresponding item in Column B based on the definitions and characteristics of different types of inflorescences. ### Step-by-Step Solution: 1. **Raceme with sessile flowers**: - A raceme is an inflorescence where flowers are attached by short stalks (pedicels) along a central stem. However, in this case, the term "sessile" indicates that the flowers do not have stalks. The correct match is **(c) Spike**, as a spike has sessile flowers directly attached to the main axis. 2. **Spike with fleshy axis**: - A spike with a fleshy axis is known as a **(e) Spadix**. This type of inflorescence has minute flowers closely arranged on a fleshy axis, typical of plants like the banana. 3. **Equal flower stalks from the same point**: - This describes an inflorescence where all flowers arise from a common point with equal length stalks, which is characteristic of an **(b) Umbel**. An example is coriander. 4. **Flattened convex receptacle bearing stalkless flowers**: - This type of inflorescence is called a **(g) Capitulum**. In this structure, the receptacle is flattened and bears numerous sessile flowers, as seen in sunflowers. 5. **Spike with pendulous axis**: - A spike that hangs down is referred to as a **(a) Catkin**. This type of inflorescence typically has flowers that are borne on a drooping spike, common in plants like oak. 6. **Cup-shaped involucre with single female flower**: - This describes a **(d) Cyathium**. In this inflorescence, there is a cup-shaped structure made of bracts that contains a single female flower surrounded by several male flowers, as seen in poinsettia. 7. **Flower stalks of varying length on a shortened raceme axis**: - This type of inflorescence is known as a **(f) Corymb**. In a corymb, the flowers are borne on stalks of different lengths but all reach the same height, creating a flat-topped appearance. ### Final Matches: 1. Raceme with sessile flowers - (c) Spike 2. Spike with fleshy axis - (e) Spadix 3. Equal flower stalks from the same point - (b) Umbel 4. Flattened convex receptacle bearing stalkless flowers - (g) Capitulum 5. Spike with pendulous axis - (a) Catkin 6. Cup-shaped involucre with single female flower - (d) Cyathium 7. Flower stalks of varying length on a shortened raceme axis - (f) Corymb
