Gymnosperms are a smaller and older group, consisting of plants that produce "bare seeds" that is, seeds that are not protected by a fruit. Recall that diploid means having two sets of chromosomes (one from each parent), whereas haploid means having one set of chromosomes. Angiosperms are plants that bear flowers and fruits. Gnetophytes (approximately 70 extant species) Gnetophytes represent an anatomically and genetically difficult group to classify. With around 300,000 species, they represent approximately 80 percent of all the known green plants now living.

Question Papers. The basal characteristics show they had flattened laminar stamens with large filaments. The anther consists of sac-like structures called microsporangia that produce pollen. The diploid plantcalled sporophyteproduces haploid spores through meiosis. Their color and fragrance serve to attract insects and other animal pollinators. Aggregate fruits are those derived from a single flower that has two or more separate carpels, each forming a tiny fruitlet. These fruitlets are grouped together in one receptacle. What are two similarities and two differences between gymnosperms and angiosperms? This website uses cookies to improve your experience. Solve. 1.

Gnetum is the only gymnosperm genus with climbing vines. The embryo is instead created by a diploid cell within the ovule, and the ovules develop into seeds. As with gymnosperms, angiosperms are heterosporous. The style is the long, stalk-like part of the carpel that raises the stigma above the ovary and other parts of the flower. Double fertilization is unique to angiosperms; it does not occur in other plants. They are found inhabiting various areas like water (hydrophytes), xeric conditions (xerophytes), moist soils (mesophytes), saline soil (halophytes) and even on other plants (epiphytes). Sepals typically resemble leaves more than other parts of the flower. The pollen grains are carried to the stigma of the ovary by various pollen agencies and thereon, it starts its development.

Angiosperms (or flowering plants) are vascular plants whose seeds are enclosed in ovaries. Fruits, grains, vegetables, trees, shrubs, grasses and flowers are angiosperms. The fruit of angiosperms provides extra nutrition and protection for the seeds. The root system of angiosperms is also very complex. Currently, Dr. Dowd is a dean of students at a mid-sized university. The seed bearing plants are broadly divided into a single class known as Spermatophyta, which is further sub-divided into angiosperms and gymnosperms. Which tissue is responsible for growth in angiosperms? In many cases, roots form an association with algae (coralloid of cycads) and fungi (mycorrhizal roots of conifers).
