After reading the paragraph below, answer the questions that follow.
The redwood groves in Northern California are one of America's greatest natural resources. Redwoods can live more than 2,000 years and grow taller than 350 feet. When tourism became popular in the late 1800s, large tunnels were cut through the center of several of these giant trees to allow wagons to pass through (and to attract tourists to the location). Even today, visitors wait in line to be photographed driving their cars through a tunnel. When the groves were converted into national parks, the tunneling was discontinued, but several tunneled trees are still alive.
What is the correct sequence of tissues a car would pass as it drives through the tree tunnel (starting from the outer surface of the tree and passing through the central core)?
◦ bark, wood rays, growth rings, lateral meristems, primary phloem, secondary phloem
◦ cork, cork cambium, secondary phloem, vascular cambium, sapwood, heartwood
◦ heartwood, wood rays, cork cambium, secondary xylem, secondary phloem, vascular cambium
◦ epidermis, cortex, primary phloem, primary xylem, heartwood, sapwood
