Quiz_Angiosperm

Explanation:”Vascular cryptogams” refers to Pteridophytes, which are vascular plants that reproduce via spores rather than seeds, including ferns and their relatives.

Explanation:Carl Linnaeus is known as the ‘Father of Taxonomy’ for developing the binomial nomenclature system and for his work in classifying and naming organisms systematically.

Explanation:Bryophytes are considered the most primitive group of embryophytes, as they represent the earliest land plants with simple structures and life cycles.

Explanation:Capsella bursa-pastoris, a flowering plant, exhibits a diplontic life cycle where the diploid sporophyte is the dominant phase, and the haploid gametophyte is reduced to the gametes.

Explanation:Endemic species are those that are highly restricted in their distribution, often found in a specific geographic area and nowhere else. This limited range makes them particularly vulnerable to environmental changes and habitat loss.

Explanation:Cycas, a genus of gymnosperms, does not produce fruits. Fruits are a characteristic feature of angiosperms, which include dicots and monocots.

Explanation:Ferns are sometimes referred to as the “snakes of the plant kingdom” due to their creeping and spreading growth habit, resembling the movement of snakes.

Explanation:Double fertilization in angiosperms involves one sperm nucleus fusing with the egg cell to form a zygote, and the other sperm nucleus fusing with two polar nuclei to form the triploid endosperm. This unique process is essential for the development of both the embryo and the endosperm.

Explanation:In tracheophytes (vascular plants), meiosis is always sporogenic, meaning it occurs during the formation of spores, which then develop into the gametophyte generation.

Explanation:Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid gametes (sperm and egg cells). This process is essential for sexual reproduction and genetic diversity.
