Question
Chapter 21, Problem 2WIO
Summary Introduction
To determine:
The reason for the observation of nutrient deprivation signs in root-bound plants.
Introduction:
Plants that have been placed in a pot for multiple years become root-bound. When a plant is grown naturally in the ground, it spread its roots throughout the soil, but in a pot, the roots start to twist and grow in a circle at the bottom of the pot.

- When farmers apply too much fertilizer to the ground, the solute concentration is higher in the soil than it is in the roots. Explain how this would affect plants. And place these structures in the order that water passes through them during transpiration: endodermis, root cortex, root hair, spongy mesophyll, stomata, and xylem. -Thank you!arrow_forwardEvery winter, the cohesion of water molecules in xylem is interrupted by ice formation. What do trees do in the spring that compensates for this problem?*arrow_forwardAndoy regularly visits his rice field each morning to see if the plants are growing healthy with profuse tillers. He likewise patiently sees if the irrigation is timely set for each paddy to have sufficient water to sustain the growth. As he continues going around places, he noticed some plants that exhibit drying up of tillers, particularly the sheaths, extending up to the leaves. These plants are situated on paddies near the source of irrigation water and scattered within each plot. He is quite alarmed by the condition thereby pulling out few affected plants and he thought of bringing it to Luis, an extension personnel in their municipality. Luckily Luis is around to help him diagnose such abnormality. He interviewed Andoy regarding the environmental conditions and recent cultural practice(s) applied to the plots such as fertilization, application of pesticides, among others. Luis feels that knowing these may help him trim down the possibilities whether the drying may be…arrow_forward
- How does acid rain lead to a reduction in the amount of plant nutrients available in soil? O Cation exchange leads to covalent bonding of nutrients on soil particles, making them unavailable to plants. O Nutrient cations (like K*, Ca++ etc) bind in place of protons released by soil particles, making the nutrients unavailable and the soil water more acidic. O Cations exchange places with anions during cation exchange, which confuses roots and turns LATS into HATS, after which the endodermis generates a caspian endothelium O During acid rain nutrients leach away after cation exchange takes placearrow_forwardWhich of the following processes enables a plant to extract nutrients from the soil? O Nutrient anions (sulfate, phosphate, nitrate, etc) are replaced by Cl on soil particles. Released nutrients become available in the soil water. Anions exchange places with cations during anion exchange, which confuses roots and turns HATS into LATS, after which the endodermis synthesizes a caspian endothelium O Cation exchange facilitates the breaking of covalent bonds between nutrients and soil particles O Protons replace nutrient cations on soil particlesarrow_forwardDescribe how water and minerals move in xylem.
