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.
The Region of Elongation. This region is merged with the upper (toward the soil surface), region of the root apical meristem. It is in this region that the cells become several times their original length, and somewhat wider.he radicle may thicken into a taproot with many branching roots, or it may develop into many adventitious roots. The direct opposite of a taproot system is a fibrous root system. This develops out of the many adventitious roots. In diameter, the roots in a fibrous system are very fine.
