Food made in leaves through photosynthesis is transported to other plant parts by phloem tissue. The sieve tubes carry dissolved sugars and nutrients from leaves to roots, stems and fruits. Companion cells assist sieve tubes by regulating sugar loading and unloading. This transport system distributes food throughout the plant for growth, storage, respiration and other metabolic activities.

Desert plants benefit from a thick cuticle because it reduces water loss by transpiration and protects them from dry conditions. Aquatic plants live surrounded by water and need easy exchange of gases and substances with their environment. A thick cuticle would block these exchanges, reduce flexibilRead more
Desert plants benefit from a thick cuticle because it reduces water loss by transpiration and protects them from dry conditions. Aquatic plants live surrounded by water and need easy exchange of gases and substances with their environment. A thick cuticle would block these exchanges, reduce flexibility and interfere with normal absorption, making it disadvantageous for underwater plants.

Xylem vessels and tracheids are dead, hollow cells that form continuous tubes for water transport. Living cells in leaves lose water through transpiration from stomata, creating a suction force called transpiration pull. This pull draws water upward through xylem against gravity. Thus, dead xylem ceRead more

There is a direct relationship between the diameter of a teak tree and the number of annual rings formed. As the tree grows older, more annual rings are added and the stem diameter increases gradually. These rings are produced by lateral meristematic activity. Therefore, counting annual rings helpsRead more
There is a direct relationship between the diameter of a teak tree and the number of annual rings formed. As the tree grows older, more annual rings are added and the stem diameter increases gradually. These rings are produced by lateral meristematic activity. Therefore, counting annual rings helps estimate both the age and growth pattern of the tree.

If stomata were absent, plants would face serious problems in gaseous exchange and transpiration. Carbon dioxide could not enter properly for photosynthesis and oxygen release would decrease. Transpiration pull responsible for upward water movement would also reduce. Plants would overheat, transportRead more
If stomata were absent, plants would face serious problems in gaseous exchange and transpiration. Carbon dioxide could not enter properly for photosynthesis and oxygen release would decrease. Transpiration pull responsible for upward water movement would also reduce. Plants would overheat, transport less water and minerals and fail to perform important life processes efficiently for healthy growth.
