Explanation

Soil salinity is measured using a conductivity meter, which assesses the electrical conductivity of the soil.

Explanation

Explanation

Divergent evolution occurs when two or more species evolve from a common ancestor and adapt to different ecological niches, leading to increased differences between them over time.

Explanation

During phase 1 of this cycle, the CO2 molecule is incorporated into one of two 3-phosphoglycerate molecules (3-PGA).

This process requires the enzyme RuBisCO and both ATP and NADPH.

Once 3-PGA is formed, one of two molecules formed continues into the reduction phase (phase 2).

Explanation

Pteridophytes are the first terrestrial plants to possess vascular tissue.

A pteridophyte is a vascular plant (with xylem and phloem) that reproduces by means of spores.

Because pteridophytes produce neither flowers nor seeds,

They are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden.

Explanation

Wind-pollinated flowers have a large, feathery stigma in order to trap the airborne pollen grains.

Examples of plants that participate in wind pollination are wheat, rice, corn, and barley.

Explanation

Plants in the Solanaceae family have an obligately superior ovary.

In the Solanaceae family, the ovary is oblique in position due to the tilting of posterior carpels to the right and anterior carpels to the left at an angle of 45 degrees.

The ovary is superior, bilocular with many ovules on swollen axile placentation.

Explanation

Explanation

 Sweet peas are annual climbing plants with fragrant, butterfly-shaped flowers. 

They are part of the genus Lathyrus within the Fabaceae family. 

The name Lathyrus is derived from the Greek word for "pea," and odoratus means "scented". 

They are cultivated for their beautiful and fragrant flowers.

Explanation

During the day, plants perform photosynthesis, absorbing carbon dioxide and releasing oxygen.

At night, in the absence of sunlight, they undergo respiration, where they take in oxygen and release carbon dioxide.
