What is Shodoshopchaar and Panchopchar pooja in Hinduism?

In Hindu ritual, some one must have heared about Shodoshopachar puja and Panchopchar pooja. Here, pooja means worship to God. In Hindu, worship rituals Shodoshopchar means worship with 16 offers to God with complete feeling and Panchopchar means only five offering worship. Basically, Shoodoshopchar pooja is specially done on some occasional worship. Panchopchar pooja is done on daily basis. In Panchopchar pooja, 5 things are offered generally, those are Gandh (Fragrance), Dhoop (Fragrance with Smoke or Inccense stick), Deep (Fire lamp with Cow ghee), Pushp (Flower), Naivaidya (Food like fruit or sweets). In Hindu temples, on daily basis God and Godess are being worshiped with panchopchar poojan. But in special occassion or tithis special Shodospchar puja is performed. All these activities are also called as Karmakand. Performing these activities by offering without feelings in mind will not be 100℅ fruitful unless creating feeling in mind.
Also there is a Pooja called Manas Pooja, in which God or Goddesses are not actually offered any physical material but only the worshiper imagine about offering  and create feelings in mind. Such a imagination worship means Manas Pooja   brings 100℅ fruitfulness for devotees.
