D, visible light is necessary to drive chemical reactions involving the pigments called chlorophylls
Pelargondin is a phytochemical (chemical from plants), belonging to the category of anthocyanidin, and is responsible for orange pigmentation. It can be found in red germaniums (Geraniaceae), spathes of Philodendron (Araceae), plums, pomegranates, and berries such as ripe raspberries and strawberries, and even blackberries, blueberries, and cranberries.
The chemical structure of pelargondin is shown in the figure below.
Answer:
Pinocytosis can be recognized when the CELL IS ENGULFING EXTRACELLULAR FLUID
Explanation:
Pinocytosis is the process whereby the cell takes in macromolecules such as bacteria and antigens in form of fluid from the extracellular fluid.
The macromolecules in the form of droplets of fluid bind to the outer surface of the cell
The cell membrane enviginates around the droplets of fluid and are engulfed by the cell.
They form vacuoles with the macromolecules and are transported into the inner of the cell.
The formed structure is called ENDOSOMES which lysozomes combine with and form secondary endosomes containing enzymes to break down the macromolecules.
Pinocytosis is also called CELL DRINKING.
