Answer 1

The correct option is D A-$2$, B-$1$, C-$3$, D-$4$

The arborescent lycopods dominated many coal-swamp plant communities of the Middle Pennsylvanian. A relatively small number of important species occurred in coal swamps, each with distinctive ecological requirements reflected in their reproductive biology. The major genera in the late Middle Pennsylvanian age Herrin Coal of the Illinois Basin were Lepidophloios, Lepidodendron sensu.

The flower with the world’s largest bloom is the Rafflesia arnoldii. This rare flower is found in the rainforests of Indonesia. It can grow to be 3 feet across and weigh up to 15 pounds, It is a parasitic plant, with no visible leaves, roots, or stem. It attaches itself to a host plant to obtain water and nutrients.When in bloom, the Rafflesia emits a repulsive odor, similar to that of rotting meat. This odor attracts insects that pollinate the plant.

Ovules of Cycas are largest in the plant kingdom and oval in shape. The mature ovule of Cycas circinalis may reach upto 6 cm long and 4 cm in diameter and the sperms are visible with naked eyes.

The tallest trees in the world are redwoods (Sequoia sempervirens), which tower above the ground in California. These trees can easily reach heights of 300 feet (91 meters).

Hence, the correct answer is (D)
