Description of Flowering Plants / Floral Formula
-
Given below are two statements:
Statement I: In a floral formula % stands for zygomorphic nature of the flower, and $\bar{G}$ stands for inferior ovary.
Statement II: In a floral formula $\oplus$ stands for actinomorphic nature of the flower and $\underline{G}$ stands for superior ovary.
In the light of the above statements, choose the most appropriate answer from the options given below:In Statement I of the original paper, the symbol given was circle-plus for zygomorphic and G-bar for inferior ovary, rendering Statement I incorrect while Statement II is correct.
In floral formulas: $\oplus$ denotes actinomorphic symmetry, % denotes zygomorphic symmetry, $\underline{G}$ denotes a superior ovary (hypogynous flower), and $\bar{G}$ denotes an inferior ovary (epigynous flower). Statement I inverted the symmetry notation and is incorrect, while Statement II is correct.
Structure of Monocotyledonous Seed
-
In the seeds of cereals, the outer covering of endosperm separates the embryo by a protein-rich layer called:
The proteinaceous layer separating the embryo from the endosperm in cereals is the aleurone layer.
In monocot cereal seeds (such as maize), the outer covering of the endosperm separates the embryo by a special proteinaceous layer termed the aleurone layer.
Flower Symmetry
-
Which of the following is an example of a zygomorphic flower?
Pea has a zygomorphic (bilaterally symmetrical) flower.
Zygomorphic flowers can be divided into two equal halves in only one vertical plane (bilateral symmetry), e.g., pea, bean, Gulmohar, Cassia. Datura, chilli, and mustard have actinomorphic (radial symmetry) flowers.
