Exam 16: Reproduction, Growth and Development of Flowering Plants

In Arabidopsis, the formation of floral whorls is controlled by

Flowers are composed of four whorls of transformed 'floral leaves' around the tip of the flower stalk. The female reproductive organs are found in the

The testa of a plant is

In epigeal germination of flowering plants the

In plants, totipotent callus cells

In the life cycle of a flowering plant, meiosis occurs in cells within the

With respect to mature pollen grains, which of the following statements is INCORRECT?

Plant cells are unlike animal cells in that

Asexual reproduction in flowering plants

In flowering plants, self-pollination has many advantages, including

Relative to their size, pollen tube cells are extremely large. How do such very large cells keep the necessary organelles and nutrients concentrated at the growing tip?

In the female reproductive structures of flowering plants, which of the following structures is contained within all the others?

A mature pollen grain is typically released in a desiccated state. As such, which of the following must a receptive stigma provide in order for a pollen tube to fertilise an ovary, and why?

In the reproductive pathway leading to the formation of the seed, which of the following is last to form?

Which of the following is NOT a developmental change that occurs in flowers post-fertilisation?

The plant Arabidopsis is widely used to understand plant function. There are many reasons for its successful use EXCEPT

A pistil cross-pollinated with same species pollen from a plant known to be S₁S₂ at the self-incompatible locus S produces offspring that are S₁S₂ or S₂S₃. The genotype of the female parent is most likely to be

In typical flowering plants, the female gametophyte

The life cycles of typical plants differ from the life cycles of typical animals because
