You should know exactly how the structures of plant tissues and organs are directly related to their functions in physiological processes.

You are watching: If the xylem in a young tree is damaged, which process is first affected?

plant organs are minimal to roots, stems, leaves, flowers, fruit and also cones. Physiological processes are restricted to photosynthesis, to move respiration, transpiration, and also reproduction. Plant tissues are limited to meristematic, ground, dermal and vascular tissues. Plant frameworks are limited to cambium, guard cells, phloem, seed, stomata and also xylem.

Terrestrial plants have stomata top top the surface of your leaves. A solitary stomata is surrounded by two guard cells that readjust shape in an answer to environmental factors and also open or close the stoma. Which of the complying with best explains how the framework of the leaf is supplied in processes that occur in plants?

A. Water beginning the plant with the surface ar of the sheet for transpiration

B. Gases because that photosynthesis are exchanged through the surface of the leaf.

C. Power for cellular reproduction is absorbed through the surface of the leaf.

D. Carbon dioxide beginning the plant with the surface of the sheet for to move reproduction.
