Answer:
Sporophytes were branched before the evolution of vascular tissues
In early land plants the gametophytes were branched and complex like the sporophytes
Explanation:
The fossil record shows that early land plants appeared in the Ordovician Period, approximately 470 million years ago (Mya). These plants were non-vascular plants (e.g., mosses and liverworts) which can be recognized as fossilized spores. Thus, the first land plants could not transport nutrients like sugar, water, or minerals around the plant. Nowadays, it is believed that early land plants had gametophyte dominant life cycles (haploid life phase), while vascular tissues evolved as an adaptation to life on land, in the sporophyte (diploid life phase).

Answer:
Answer 4: Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red (therefore, blue and red are useful for photosynthesis, but green isn't).
<h2>
Correct Answer is (C)</h2>
Explanation:
(C) Use of reporter genes
- <em>Reporter gene</em> A quality that is utilized to<em> 'tag' </em>another quality or DNA succession of interest, for example, <em>an promoter</em>
- Expression of the correspondent is handily observed, and allows the function or whereabouts of the<em> 'target' sequence</em> to be tracked.It have a two type of reporter gene such as scorable reporter gene and selector gene
- Scorable reporter gene - The gene have expression of this result in quantifiable phenotype and easily detected through highly<em> sensitive enzymes assays </em>
- Selector gene- The gene expression<em> resistance to a toxin</em> and selection of tranformants from <em>non tranformants in growth media containing selective agents </em>
