Chapter 28, Problem 2TYK
Summary Introduction
Introduction:
The plants are multicellular organisms that fall under Eukaryota group of organisms. The early plants used to live underwater and during the course of evolution, they adopted a terrestrial life. The plants are the ultimate source of nutrition to all living organisms because they are able to perform photosynthesis and produce oxygen as a byproduct. The released oxygen is the main driving force for most of the organisms, including humans.

Biologist hypothesize that the first land plants had a low, sprawling growth habitat. Which of the following is part of the logic behind that theory? A. The low sprawling growth gave them greater surface area exposed to light for photosynthesis. B. This was prior to plants’ development of adaptations to defend themselves from predators, so by growing low they were out of sight of most predators. C. The wind speed was much greater at that time that it is now, and pushed the plants over. D. To obtain water, they had to keep their tissues in direct contact with moist soil. 2.
