Question

which of the following accurately describes the correct order of events in the process of transpiration within a plant?
a) water enters the roots, passes through the leaves, and leaks through the stem pores.
b) water is absorbed through the leaves, is transported through the stem, and nourishes the roots.
c) water is absorbed through the leaves, nourishes the roots, and leaks through the stem pores.
d) water enters the roots, gets transported through the stem, and evaporates through the leaves.

which of the following describes a phenomenon that occurs when you observe plants that wilt?
a) the roots begin to rot, causing them to no longer uptake water.
b) the stomata close, cutting off transpiration and gas exchange.
c) the plant begins absorbing oxygen and releasing carbon dioxide into the atmosphere.

Explanation:

First Question (Transpiration Order):

In transpiration, water is first absorbed by roots from the soil. Then, it moves up (transported) through the stem via xylem. Finally, it evaporates from the leaves (through stomata) into the atmosphere. Option A is wrong as water doesn't "leak" through stem pores. Options B and C are wrong because water is absorbed by roots, not leaves.

Second Question (Wilting Plants):

When plants wilt (due to water deficit), stomata close to reduce water loss (transpiration). This also stops gas exchange (like CO₂ intake for photosynthesis). Option A: Root rot is a different issue, not direct cause of wilting observation. Option C: Plants mainly do respiration (absorb O₂, release CO₂) at night, but wilting's main response is stomatal closure, not this general gas exchange shift.

Answer:

D) Water enters the roots, gets transported through the stem, and evaporates through the leaves.
