Questions: 50 | Attempts: 194 | Last updated: Oct 28, 2024

Sample Question
Photosynthesis has been occuring on this planet for approximately 3 billion years. In this time plants have evolved from small single celled bacteria in the ocean and diversified into many ecological niches. Some plants on earth such as giant sequoia manage to transport water 100s of meters into the air without the use of a pump. This is made possible by vascular tissue composed of small tubes that transport the water. They are able to do this because

Hydrogen bonds among water molecules give it cohesive properties

Water has adhesive properties

Water is polar

All of the above
