About This Video ........................
In This Video Lecture You Will Learn Basic Concept Of Method of plant nutrition
Saprophytic Nutrition
called saprophytic nutrition and derives its nutrients from host plants. They produce extracellular
are taken up by the plant roots and then built into new amino acids and proteins, thus helping in
Feeding on dead and decaying matter such as dead leaves in the soil or rotting tree trunks is
enzymes, which digest the decaying matter and then absorb the soluble products back into their cells. Some bacteria break down the proteins of dead plants and animals and release nitrates which nitrogen cycle.
Parasitic Nutrition
Feeding by living in or on other organism (host) belonging to diferent species is called parasitic
host. Puccinia is a parasitic fungus that destroys the wheat plant. Dodder (Cuscuta)is a lealess
nourishment from higher plant the parasite penetrates its suckers in the conducting tissue of the
nutrition. Parasites attach themselves to living things or their host, for nourishment. For obtaining plant that lives as a twining parasite.
About This Channel.....................
I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources.
One-stop destination for all biology lectures.
_ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial
_ The videos are categories under various heading to make the students life simplified
