Explanation

Hatch and Slack Pathway In C4 Plants.

To fix carbon dioxide, this pathway is the alternate to the C3 cycle.

The first formed stable compound – oxaloacetic acid is a 4 carbon compound,hence the name C4 cycle.

This pathway is a common sight in several grasses, maize, sugarcane, amaranthus, sorghum.

Explanation

Natural resistance refers to an organism's inherent ability to resist diseases or pests due to genetic factors.

Explanation

Gibberellins are plant hormones that promote cell elongation, especially in internodal regions.

Explanation

During phase 1 of this cycle, the CO2 molecule is incorporated into one of two 3-phosphoglycerate molecules (3-PGA).

This process requires the enzyme RuBisCO and both ATP and NADPH.

Once 3-PGA is formed, one of two molecules formed continues into the reduction phase (phase 2).

Explanation

 Imbibation is the absorption of water by materials, leading to swelling, such as in door wood during the rainy season.

Explanation

Tyloses are outgrowths from xylem parenchyma cells

They grow into the lumen of tracheary cells through pits, balloon out, and occlude the cell interior.

Tyloses are typically associated with the process of defense against pathogens

They are commonly found in the xylem of certain trees and plants.
