Explanation

• Angiosperms are flowering plants.
• They first appeared in the Cretaceous period.
• This was about 145–66 million years ago.
• They diversified rapidly.
• Today they dominate plant life on Earth.

Explanation

• Naturally occurring auxin is primarily found in the form of Indole-3-acetic acid (IAA),
• It regulates plant growth.
• It promotes cell elongation.
• Auxins influence apical dominance.

Explanation

Flower is the reproductive structure.

It contains stamens and carpels.

Pollination occurs in flowers.

Fertilization leads to seed formation.

Angiosperms are flowering plants.

Explanation

• Epiphytes grow on other plants.
• They are not parasitic.
• They obtain nutrients from air and rain.
• Common in tropical forests.
• Orchids are common epiphytes.

Explanation

Sciophytes are plants that last or thrive best at low light intensity.

These plants have larger photosynthetic units than solar plants or heliophytes.

They are shade-loving trees and plants. 

Explanation

Carolus Linnaeus  was a Swedish botanist,

He is widely recognized as the "Father of Taxonomy".

In the 18th century, he published his seminal work, Systema Naturae, in which he introduced a formal, hierarchical system for classifying and naming living organisms.

Explanation

Both gymnosperms and angiosperms are seed-producing plants (seed plants).

• Gymnosperms → Seeds are naked (not enclosed in fruit).

• Angiosperms → Seeds are enclosed within fruit.

Thus, they are correlated based on the characteristic of seed production.
