Q. Select the correct statements.
A) Absorption of water by seeds and dry wood are examples of facilitated diffusion
B) The apoplast is the system of interconnected protoplasts
C) $Pinus$ seeds cannot germinate and establish without the presence of mycorrhizae
D) The translocation in phloem is unidirectional, whereas in the xylem it is bidirectional
Explanation
A mycorrhiza is a symbiotic association of a fungus with a roots system. The fungus provides minerals and water to the roots, in turn the roots provide sugar and N-containing compounds to the mycorrhizae. Some plants have the obligate association with mycorrhizae. For example, $Pinus$ seeds cannot germinate and establish without the presence of mycorrhizae.
