Concept Map of Plants growth and development



 Cytokinins are a group of hormones that promote cell division in plant roots and shoots and the growth of buds. These hormones have been found in all complex plants as well as mosses, fungi, and bacteria. There are about 200 different natural and synthetic cytokinins known to botanists today.


Function:
Cytokinins increase cell division by stimulating the production of proteins needed for mitosis. Mitosis is non-sexual cell division that occurs in all living things producing additional cells for body growth.
In your body, mitosis is occurring every day, replacing dead and damaged cells and allowing for growth. If you skin your knee, it's mitosis that grows back the cells you lost.
Having an apical dominance in the bud, the auxin was produced. The auxin was produced in the distal part of the shoot region. The auxin moves from distal to proximal end. The auxin was transported through chemiosmosis. While having the chemiosmosis, the hydrogen ion is increasing in every plant cell. Since the hydrogen ion is increasing, the acidity of the cell wall will increase which results in cellular elongation. The cellular elongation happen because the integrity of cellulose is weaken.


I'll give you the plantpsy version. Two plants (bulls) were planted at the top of the hill looking down at a pasture of fine looking flora, the young determinate bull said to the cultured indeterminant bull and said “I am gonna vine down there and pollinate one of them fine flora”, The indeterminant bull said “vine on little one, I am gonna root down and pollinate them all.
A determinant plant has a set growth. And once it is differentiated, rarely goes back, but it continues down the set path to its death as it has been determined. And indeterminant plant is forward growing and doesn't stop until something stops it such as lack of water or food.
When NPK are put through a plant obviously the feeding veins(xylem and phloem) are at work pulling it through the system. Growth hormones are strong in phosphorus (P) which helps the roots reproduce because of the sunlight causing the photosynthesis
The fastest-growing food plant is watermeal (Wolffia globosa or Wolffia arrhiza). Each individual speck is less than a millimeter long; it has no leaves, stems, or roots. They float on the surface of calm ponds. Individual watermeal are small, but they reproduce by splitting in half, like bacteria. Each plant splits into two plants about every four days, and then four days later those plants split again, so the amount of watermeal you have doubles every four days.
The most poisonous plant in the world is probably going to be the Cerbera odollam. This species of tree belongs to the same family as Oleander, and is also quite toxic to humans. The seeds of the Cerbera odollam contain a toxin called cerberin, a potent compound capable of disrupting calcium ion channels in heart muscle, which can lead to an irregular heart beat that is often fatal if the toxin is ingested in high enough quantities. The plant has been referred to by some as the perfect murder weapon.
