Types of Heterotrophic Nutrition - Parasitic
Parasitic Plant - Cuscuta (Dodder) As can be seen in the diagram, Cuscuta lacks leaves and the roots are modified into specialised structures called haustoria . Haustoria penetrate the stem of the host and draws nutrition from the vascular system of the host directl..

The egestion takes place by exocytosis. There is no particular point from which the egestion takes place. As the amoeba moves forward, the undigested matter is shifted to the back and eliminated as food pellets through a temporary opening formed at any nearest point on the plasmalemma. ..

I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
