[2] [3] Plant intelligence has been defined as "any type of intentional and flexible behavior that is beneficial and enables the organism to achieve its goal". [4] Plant neurobiology is a subfield of plant intelligence research that claims plants possess abilities associated with cognition including anticipation, decision making, learning and ...
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
Palisade cell, or palisade mesophyll cell are plant cells located inside the mesophyll of most green leaves. They are vertically elongated and are stacked side by side, in contrast to the irregular and loosely arranged spongy mesophyll cells beneath them. Palisade cells are responsible for carrying out the majority of the photosynthesis in a ...
This proposed mechanism is a form of plant memory storage. Another potential mechanism involves electrical signals and calcium. When Ca2+ floods the cytoplasm it allows the plant to store a memory, the duration and amplitude of this Ca2+ wave is determined by the type of stimulus that was perceived and how the plant will store the memory.

Leaves contain a variety of types of sclereids. In the mesophyll , two distinct sclereid structures are found. Sclereids in a diffuse pattern are dispersed throughout the leaf tissue, and sclereids in a terminal pattern are concentrated about the tips of leaf veins .
They found that when xenon penetrated the blood-brain barrier, it altered the behavior of microglia — immune cells that change during the progression of Alzheimer’s disease.

These leaves are narrow because the width of the blade is limited by the distance water can efficiently diffuse cell-to-cell from the central vascular strand to the margin of the leaf. [3] Despite their name, microphylls are not always small: those of Isoëtes can reach 25 centimetres in length, and the extinct Lepidodendron bore microphylls up ...
