|
|
The zone of soil surrounding a plant root where the biology and chemistry of the soil are influenced by the plant root
|
|
|
Area of the cortex and endodermis of root where microorganisms can occupy spaces between cells and makes use of nutrients by roots
|
|
|
Either A or B
|
|
|
None of the above
|
Detailed explanation-1: -The endorhizosphere includes portions of the cortex and endodermis in which microbes and cations can occupy the “free space” between cells (apoplastic space). The rhizoplane is the medial zone directly adjacent to the root including the root epidermis and mucilage.
Detailed explanation-2: -endorhizosphere-the region in the root which microbes fed by root derived compounds may colonize including root cortex, epidermis and root hairs (Kloepper et al. 1992a; Lynch 1982) exudates-compounds released into the soil/rhizosphere by plant roots (Walker et al. 2003)
Detailed explanation-3: -Rhizosphere also known as the microbe storehouse is the soil zone surrounding the plant roots where the biological and chemical features of the soil are influenced by the roots. The rhizosphere is coined more than hundred years ago by Hiltner in 1904.
Detailed explanation-4: -Figure 2-Saprobionts are soil bacteria and fungi that help to feed plants by decomposing dead material in the soil, such as compost. These microbes make the nutrients in the dead matter available for plants to absorb through their roots.
