Floral Member Arrangement & Thalamus — NEET Biology
📚 Practice ConceptDescribe the arrangement of floral members in relation to their insertion on thalamus.
Which of the above statements concerning floral symmetry and related characteristics are NOT correct? S1: Actinomorphic flowers, such as those of mustard, datura, and chilli (Solanaceae members), can be divided into two equal radial halves by any radial plane passing through the centre. S2: Zygomorphic flowers, found in pea, gulmohur, bean, and Cassia, can be divided into two similar halves only in one particular vertical plane. S3: Asymmetric flowers, exemplified by Canna, cannot be divided into two similar halves by any vertical plane passing through the centre. S4: Flowers are described as trimerous, tetramerous, or pentamerous based on whether their floral appendages are in multiples of 2, 3, or 4 respectively. S5: In Solanaceae, the flowers are typically zygomorphic, despite having five petals and five stamens.
