300
Tracheids and vessel elements are cells that make up this tissue.
What is vascular tissue.

Scientists studying a new species of plant have determined that when the plant is exposed to anymore than 10 hours of night it will NOT bloom. What type of plant could this be?
What is a long-day plant.
400
Symbiotic relationship between plants and this fungi increases nutrient/water absorption.
What is mycorrhizae
