Question

Important terrestrial adaptations that evolved exclusively in seed plants include all of the following characteristics except:

• A. Pollination by wind or animal instead of swimming sperm
• B. Transport of water through vascular tissue
• C. Retention of the gametophytic plant within the sporophyte
• D. Protection and nourishment of the embryo within the seed

Answer 1

The correct option is B Transport of water through vascular tissue

Vascular tissues are conducting tissues that help in the transport of food and water in all seed bearing and seedless vascular plants. It is therefore not a characteristic exclusive only for plants showing terrestrial adaptation. Seeds and pollen grain carried by wind, water, or a pollinator, a gametophytic plant body retained within the sporophyte and a protective coat for seeds with storage tissues to provide nourishment are evolutionary adaptations of all land plants.

So, the correct option is 'transport of water through vascular tissue'.
