Scientists believe green algae to be the ancestors of land plants. The classification division separating algae from the kingdom Plantae began with fossil evidence. To be successful land plants require certain modifications. This early Devonian land plant had both vascular tissue and, as seen here,

The question is incomplete as it does not have the options which are:

A) roots. B) spores. C) seed pods. D) chlorophyll.

A) roots

Explanation:

The vascular plants are evolved from the Bryophytes which are evolved from the algae.

The algae are non-vascular plants and Bryophytes too. The vascular plants developed the vascular tissue to transport the absorbed water and nutrients from the terrestrial surface.

The plants living during the Devonian period possessed the vascular tissue to transport the nutrients but to absorb the nutrients and water, they also possessed the roots.

Thus, Option-A is the correct answer.

hi, natural selection of the peppered moth during the industrial revolution in 19th-century england is an example of an outlier in the study of evolution. during this time, pollution from factories filled the forests, coating trees in a layer of soot—turning white trees black

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
