What would a planet with no moon look like?

Consider a planet identical to Earth except that it has no moon.

1. How long is the complete day-night cycle on this planet? I've heard that having no moon would speed up the planet's rotation, resulting in a day-night cycle of 6 hours. Is this true?
2. If so, then what would the conditions be so that this planet could have a 24-hour day-night cycle without a moon? (For example, would having a larger mass make it rotate slower?)
3. What would the seasons look like on this planet? Would there be seasons at all? I've heard that having no moon means that there would be no changing seasons. Instead, certain areas of the planet would be locked in a single season, and that season would vary depending on the area.
4. Would the temperature of this planet be different compared to Earth because of its lack of a moon?
5. Are there any other notable things (besides the tides, the darker nights, and the lack of eclipses) that should be mentioned?
