HORTICULTURE

Detailed explanation-1: -Algal ancestors of land plants. The land plants arose from the green algae, and, together, land plants and green algae are sometimes called “Viridiplantae” (from the Latin viridis = green).

Detailed explanation-2: -The ancestor of all land plants was an aquatic, green algal-like species. Living in the water provides a number of advantages compared to life on land: In water or near it, plants can absorb water from their surroundings with no need for any special absorbing organ or tissue to prevent desiccation (drying out).

Detailed explanation-3: -The first land plants probably evolved from shallow freshwater charophyte algae much like Chara almost 500 million years ago.
