Plant Science

Agriculture focusses on the topic Plant Science. Plant cells are immobile, encased during a fixed cell membrane . Unlike animal cells, migration and programmed necrobiosis play less role within the patterning of plant cells fates, nor can they move when their environment changes. If the availability of food is a smaller amount or if there's a predator, animals can move, fight or fly. But plants cannot. they need to adapt constantly to their environment and their development is very plastic. Development of the animal is usually embryonic. the form of the body is defined during embryogenesis and therefore the adult derive from the enlargement of the embryo. In contrast, in plants, most of the event takes place post-embryonically and never ceases. In fact, because plants can't shake their physical locations, they adapt and "escape" through development. When there's a scarcity of nutrients or energy, the plant develops its rootage to explore the bottom or its aerial system to urge some light. under fire from a pathogen or herbivore, the plant is in a position to synthesize signalling molecules to vary its development and defend itself.
