Question 3

vascular tissue of roots

Answer 3

Xylem
Tracheids: These are long, tapering cells with thick walls and small pits.
Vessel Elements: Vessel elements are shorter, wider cells with perforated end walls.
Parenchyma and Fibers: store food or perform metabolic functions, while fibers provide structural support to the xylem.
Phloem
Sieve Tube Elements: These are the main conducting cells of the phloem. They are elongated cells with perforated end walls called sieve plates.
Companion Cells: Each sieve tube element is associated with a companion cell, which provides metabolic support and energy to maintain the transport processes in the phloem.
Parenchyma Cells: may also contain parenchyma cells that store sugars and perform various metabolic functions.

Answer 5

Honestly look it up

Question 6

mycorrhizae

Answer 6

increased nutrient absorption, enhanced tolerance to environmental stress (such as drought and disease), improved root development, and overall healthier growth.

Question 7

root nodules

Answer 7

enables fix to atmospheric nitrogen. It reduces the plant’s reliance on external sources of nitrogen, such as synthetic fertilizers or nitrogen-rich organic matter. (Nitrogen fixiation)
