Changing the orientation of their leaves in different directions (parallel or perpendicular) allows plants to reduce damage from intense light. Leaves also wilt in response to stress, because it changes the angle at which the sun hits the leaf. Leaf rolling also minimizes how much of the leaf area is exposed to the sun. [2]
Wound healing in Quercus robur. Two branches, cut at different times, have regrown branch collars , but the wood inside has become wet and is being rotted by fungi. Plants respond to injury by signalling that damage has occurred, [ 11 ] by secreting materials to seal off the damaged area, [ 12 ] by producing antimicrobials to limit the spread ...

[8] It can also host the phytoplasma bacterium which causes stunting in Napier grass ( Pennisetum purpureum ), and its infection has been dubbed Hyparrhenia grass white leaf disease.
The orangutan chewed the plant's leaves to produce a liquid that Rakus repeatedly smeared on the wound and then applied the chewed-up plant material directly to the injury, much like a wound ...
Leaf scars are formed naturally, often at the end of the growing season for deciduous plants when a layer of cells called the abscissa layer forms between the petiole and stem. The abscission layer acts as a point of cleavage and the leaf breaks off leaving a cleanly shaped wound that is quickly healed over with protective cork.
The antibacterial effect of Mikania and its efficacy in wound healing has been reported. In Assam (NE India), Kabi tribes use the leaf juice of Mikania as an antidote for insect bite and scorpion sting. The leaves are also used for treating stomachache. Use of juice of Mikania as a curative agent for itches is reported from Malaysia.
Dry leaves, along with dry grass, dead plants, wood chips, shredded paper, and sawdust are examples of carbon to place in the compost. Oxygen or green material includes grass clippings, produce ...
[3] [4] It is also called agueweed, feverwort, or sweating-plant. In herbal medicine , the plant is a diaphoretic , or an agent to cause sweating.
