Select the correct statements.
- Absorption of water by seeds and dry wood are examples of facilitated diffusion
- The apoplast is the system of interconnected protoplasts
- seeds cannot germinate and establish without the presence of mycorrhizae
- The translocation in phloem is unidirectional, whereas in the xylem it is bidirectional
The correct answer is: seeds cannot germinate and establish without the presence of mycorrhizae
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, seeds cannot germinate and establish without the presence of mycorrhizae.
