Cultivated sunflowers only have one central bloom and then set seed. They do not rebloom. However wild varieties will send up buds for sometimes 20 or more additional flowers. Deadheading isn't necessary to achieve this because they usually bloom around the same time. Also if left alone they will reseed themselves generously and you will have plenty of volunteer sunflowers next year.

If by "open up" you mean "bloom", then yes.
They will not re bloom. They will bloom in a vase of water if cut before blooming.
Plants can flower regardless of whether they are perennial or annual, so no, blooming does not automatically make a sunflower a perennial.
A sunflower faces the sun during the day because it needs sunlight for photosynthesis. * During the day a young sunflower's flower head faces the sun to receive the sunlight it needs for photosynthesis . Heliotropism is the term for a plant's ability to follow the sun. That ability allows a sunflower to move with the sun as it arcs across the sky from east to west ; the sunflower's bloom always faces the sun . The neck of the sunflower's stem, just below the bloom, points the bloom in the direction of the sun . In early morning, plant cells on the western side of the stem begin to grow and elongate, causing the sunflower bloom to tilt toward the sun. As the sun moves across the sky, the cells on the stem's side that is opposite the sun elongate, keeping the flower head facing the sun .

The "big breasted babe" sunflower will only bloom once you find all the "tickly bees" on the map. Once found, they need to be escorted back to the sunflower. The bees aren't hard to find, just keep exploring the map.
Sunflowers will bloom naturally when they are ready. It can take several weeks from the initial formation of the head to develop fully and bloom.
