Sladkaya [172]

Answers

1. True, trees shed their leaves during winter to survive the harsh winter.

2.  True, some trees have leaves that are pointed needles to survive the cold.

Explanation

Trees lose their leaves during winter , during this period, the ground freezes making the soil to be dry as in desert, hence to reduce loss of moisture through transpiration that occurs via the leaves, the trees shed all leaves until warmer springs start. For example deciduous trees in temperate forest shed leaves every winter.

Needle like leaves can survive ice and snow during cold. Insects will not be able to feed on such leaves because of their toughness. In addition to that, needle shaped leaves have lower wind resistance thus can not easily make a tree fall over during big storms.
