5. Write a short note on the adaptations in pine and fir.
Answers
Answer:
Pine cones protect the seeds during the harsh winter. The thin waxy needles reduce water loss. Their evergreen nature means that the needles can photosynthesise whenever there is sufficient sunlight. The dense forest creates warmth during the harsh winter. and Firs (Abies) are a genus of 48–56 species of evergreen coniferous trees in the family Pinaceae. They are found through much of North and Central America, Europe, Asia, and North Africa, occurring in mountains over most of the range. Firs are most closely related to the genus Cedrus (cedar). Douglas firs are not true firs, being of the genus Pseudotsuga.
The genus name is derived
Explanation:
PINE
•Coniferous trees have thick bark to protect against the cold. They are cone-shaped, with flexible branches which help them to cope with heavy snow fall.
•Pine cones protect the seeds during the harsh winter. The thin waxy needles reduce water loss.
•Their evergreen nature means that the needles can photosynthesise whenever there is sufficient sunlight.
•The dense forest creates warmth during the harsh winter.
FIR
•Fir trees, like most conifers, have adventitious roots, thick barks, and rapid life cycles to help them survive in extreme conditions and withstand forest fires.
•Fir trees are equipped with special root structures, called adventitious roots, which grow directly from their trunks to help keep them anchored on steep mountain slopes and resist strong pressure from blowing winds
•Fir trees also have thick bark that is nearly twice as thick as the bark of many other trees.
•This bark protects the trees from the extreme heat generated by forest fires and helps hold water in times of water scarcity.
• Firs also have rapid life cycles and produce seedlings early in life to help the species survive.
