Anatomy and Functions of Flowering Plants' Reproductive Systems Quiz

Double fertilization is a characteristic feature of flowering plants where two sperm cells fertilize two cells in the ovule, leading to the formation of the embryo and endosperm. This process is unique to flowering plants and sets them apart from other plant groups.

Male gametophytes of flowering plants are referred to as pollen grains because they contain the male gametes that are necessary for fertilization.

A stamen is the male reproductive part of a flower, consisting of an anther (produces pollen) and a filament (supports the anther). The incorrect options provided do not accurately describe the components of the stamen.

Pollination involves the transfer of pollen grain to the stigma of a flower for fertilization to occur. The pollen needs to reach the stigma in order for successful pollination to take place.

Ovules are found within structure B, which is the ovary of a plant. The ovary is the female reproductive organ where ovules are housed and fertilization occurs.

In flowering plants, the integument of the ovule develops into a seed coat, which protects the developing embryo within the seed. It is not correct to say that the integument develops into a pollen grain, petal, or stigma as these parts have different functions in the reproductive process of plants.

A carpel is the female reproductive organ of a flower and is composed of stigma, style, and ovary. The stigma is the receptive surface for pollen, the style is the slender stalk that connects the stigma to the ovary, and the ovary contains the ovules which develop into seeds.

In flowering plants, one megaspore gives rise to eight haploid nuclei through the process of mitosis in the female gametophyte generation.

Endosperm is a tissue inside the seed that provides nutrients to the developing embryo through the cotyledons.

The correct answer is 'embryo' because a diploid cell develops into an embryo through the process of fertilization and subsequent cell division to form a new organism. The incorrect answers are 'sperm cell', 'muscle cell', and 'red blood cell' as these do not accurately represent the development of a diploid cell into an embryo.

Fruits evolved primarily as structures specialized to disperse seeds in order to ensure the plant's offspring are spread to new areas for better chances of survival.

Golden rice is pale yellow in color due to its high beta-carotene content, which gives it its characteristic hue. Beta-carotene is a precursor to vitamin A, which is important for vision, immune function, and overall health.

Vitamin A deficiency can lead to a condition called 'night blindness' which can progress to complete blindness if not treated. Other symptoms of vitamin A deficiency may include fatigue, muscle weakness, and headaches.

Beta-carotene is a pigment found in plants that the body can convert into Vitamin A, making it a precursor of this essential nutrient.

The transfer of antibiotic-resistant genes from genetically engineered bacteria to disease-causing bacteria is a complex process with certain barriers in place that make it unlikely. Genetically engineered bacteria are typically modified in such a way that reduces the possibility of gene transfer to disease-causing bacteria.
