Question

The giant Redwood tree (Sequoia sempervirens) is a/an …………..
(A) Angiosperm
(B) Free fern
(C) Pteridophyte
(D) Gymnosperm

Answer 1

Hint: The Sequoia sempervirens belong to the genus Sequoia under the family cupressaceae these are classified into coast redwood, coastal redwood and the California redwood. It has the longest lifespan and is the tallest in nature. Although they are tallest, they occupy the narrow space of land.

Complete Answer:
- The Sequoia sempervirens are the gymnosperms since they do not possess flowers. They are present mainly in the mountains where precipitation from the approaching dampness off the sea is more prominent.
- The tallest and most established trees are found in profound valleys and ravines, where all year streams can stream. The trees over the haze layer, above around 700m, are shorter and littler because of the drier, windier, and colder conditions.
- Moreover, they do not have flowers but they bloom Douglas fir, pine, and tanoak regularly swarm out redwoods over the leaves at these heights. Scarcely any redwoods develop near the sea, because of extraordinary salt splash, sand, and wind.
- Mixture of beach front haze represents an impressive aspect of the tree's water needs. Coast redwoods are impervious to bug assault, parasitic disease, and decay. This causes the convergences of terpenoids and tannic corrosive in the redwood leaves, roots, bark, and wood.
- Despite these synthetic guards, redwoods are as yet dependent upon bug invasions. Hence the giant redwood tree is a gymnosperm.

Thus the option (D) is correct.

Note: These plants reproduce sexually or asexually. They undergo the sexual method of reproduction by producing seeds and also they produce cones for the asexual reproduction. These asexual cones look like flowers when young and undergo maturation to form a new plant.
