Question 1

haustoria

Answer 1

structures that attach parasite plant to host plant, have strong physiological /metabolic connection, may invade vascular tissue of host

Question 2

holoparasite

Answer 2

gets ALL of carbon from host,

non photosynthetic (white coloring)
all obligate parasites

Question 3

endoparasite plants

Answer 3
