do pines have sclerenchyma ?
Asked by elmencorp | 26th Jul, 2017, 06:36: PM
The Pine tree does have sclerenchyma tissue. The leaves of Pine tree are adapted to tolerate cold conditions in which liquid water may be scarce. For this, the leaves of Pine tree consist of a pair of tough needles enclosed about their bases by a common sheath. Beneath the epidermis of pine needles are one or more layers of strengthening fibrous sclerenchyma cells forming a hypodermis. These strengthen the needle and prevent it from collapsing when dehydrated or frost-damaged. The epidermis also tends to be lignified, strengthening and waterproofing it.
