Detailed explanation-1: -All green algae (Chlorophyta) and plants share a common evolutionary ancestor. They both contain the photosynthetic pigments chlorophyll a and chlorophyll b. The two lineages diverged between 630 million and 510 million years ago.
Detailed explanation-2: -The green alga lineage (eukaryotes containing primary green plastids) originated as much as 1500 million years ago (mya; Yoon et al., 2004), and the divergence of land plants occurred perhaps 700 mya (Heckman et al., 2001) or more likely 425–490 mya (Sanderson, 2003).
Detailed explanation-3: -The characteristic features of algae include autotrophic chlorophyll-bearing thalloid plant body, lacks sterile tissue around its reproductive structures, and zygote development is by mitosis or meiosis but not via embryo formation.
Detailed explanation-4: -Green Algae (Chlorophyta) They have a nucleus and and two membranes around their chloroplasts. Green algae are similar to plants because they share similar chloroplast structure, photosynthetic pigments, and metobolic storage products (e.g. starch).
