You will need the alleged father (your ex-husband) to test along with your sisterâs older son in order to determine paternity through a DNA paternity test. If you would like to determine siblingship, you can take a sibling test (testing your daughter and your sisterâs older son).
The Advantages of the Fibrous Root & Taproot Systems. Fibrous roots branch from the plant's base, and taproots go straight down. Unseen and buried beneath the soil, plant roots perform functions that are necessary to a plant's life. The roots collect water and nutrients for the plant and secure it to the soil. Two basic types of root systems exist. One type is the taproot, which grows vertically and has lateral branches. The other type has fibrous, branching roots that make a network close to the soil surface. Some plants have either a taproot or fibrous roots, and other plants combine the two systems.
Taproot system. The two basic types of root systems are the primary root systems and the adventitious root system. The primary root systems is formed of roots and their branches that arise from the primary root. The primary root is the first-formed, main root, That originates from the radicle of a seed embryo (the portion of the embryo below the cotyledons). Two primary root system types: Taproot system-Single primary root dominates over branch roots (usually found in Gymnosperms and most Dicotyledons). Fibrous root system A network of fine roots with no central dominant root.
