Evolution of Land Plants. Land plants evolved from green algae. The green algae called charophyceans are the closest relatives of land plants. Comparisons of both nuclear and chloroplast genes. Point to charophyceans as the closest living relatives of land plants. Topic 1.2.. Pg. 54-56. Kingdom Plantae. Land plants – some terrestrial, some aquatic..

Dementia is a serious brain disease that affects memory, ability to make decisions, daily functioning, as well as mood and behavior. Vascular dementia is a type of dementia caused by a stroke. Alzheimer’s is the most common form of dementia and vascular dementia is the second most common for people age 65 and older. .
