What Is Soil Structure? Soil structure is the overall arrangement of soil particles into clusters or aggregates of various sizes and shapes. Aggregates that occur naturally in the soil are referred to as peds, while clumps of soil caused by tillage are referred to as clods. In other words, Soil structure is determined by how … Read more
The Bilateral (and Coelomate) phyla can be divided into two groups, variously called the Schizocoela and Enterocoela, or the Protostomia and Deuterostomia. These are distinguished by embryonic cleavage patterns, the fate of the blastopore and coelom formation. The Deuterostomes are a relatively small (in terms of species and abundance) group that includes vertebrates, echinoderms, and a few assorted … Read more
Structure of Leaf Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf. Some leaves are attached to the plant stem by a petiole. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. Leaves also have … Read more
What Are R-selected Species? R-selected species also referred to as r-strategists are species whose populations are governed by their biotic potential (maximum reproductive capacity, r). The production of numerous small offspring followed by exponential population growth is the defining characteristic of r-selected species. They require short gestation periods, mature quickly (and thus require little or no parental care), and possess short life spans. Unlike K-selected species, … Read more
What Is A Cladogram? A Cladogram is a type of diagram that shows hypothetical relationship between groups of organisms, including their common ancestors. The term “cladogram” comes from the Greek words clados, which means “branch,” and gramma, which means “character.” The diagram resembles the branches of a tree that extend outward from a trunk. However, the shape … Read more
The Bunsen burner has a controllable air supply and a constant gas jet, therefore when the air supply is reduced; a highly visible, yellow/orange ‘safe flame’ is produced. For heating work, the air inlet is opened and the burner produces a much hotter blue flame. Therefore, the two flames produced by a Bunsen burner can … Read more
What Are Ruminant Animals? Ruminants also referred to as ‘’polygastrics’’ are herbivores with a complex (four-part stomach) which allow them to chew food more than once. Parts of their stomach structure include, Rumen, Reticulum, Omasum and abomasums. The rumen and the reticulum are connected and work in concert and are therefore sometimes referred to as … Read more
What Does Stomata Mean? Stomate also referred to as Stoma, plural stomata or stomas , are any of the microscopic openings or pores in the epidermis of leaves and young stems. The Stomata are generally more numerous on the underside of leaves. They provide for the exchange of gases between the outside air and the … Read more
What Is Springwood? In the spring season, cambium is very active and produces a large number of xylem elements having vessels with wider cavities. It produces a large number of xylem elements. This xylem contains bigger and several pores which are regularly xylem vessels with wider opening and lumens. The lumens are having fewer fibers … Read more
