Tens of thousands of opponents have massed in Tahrir Square and outside Cairo's main presidential palace.
Four people died in violent incidents in provincial cities.
In Cairo, stones and petrol bombs were thrown at the headquarters of the ruling Muslim Brotherhood.
Protest leaders have called on demonstrators to stay on the streets until Mr Morsi resigns. They accuse the country's first Islamist president of failing to tackle economic and security problems since taking power a year ago.
A presidential spokesman urged the protesters to respect the democratic process while Morsi supporters massed in the Cairo suburb of Nasr City.
One clear achievement of the protesters has been to get so many people out on to the streets, BBC's Middle East editor Jeremy Bowen reports from Cairo. The question they face now is how to fashion a political strategy that can rival the organisation of the Muslim Brotherhood, he says.
Another big question, he adds, is what the army will do. The minister of defence has warned that the military may intervene if Egypt becomes ungovernable.
One man was killed and at least 24 injured in Beni Suef, 115km (71 miles) south of Cairo, security sources said. According to a report on the Ahram news website, Morsi supporters attacked an opposition rally and unidentified gunmen opened fire. The report could not be confirmed independently.
In the southern city of Assiut, three people died and several were injured when shots were fired at protesters, reportedly by attackers on a motorcycle.
According to the health ministry, 253 people were injured across the country during Sunday's protests.
In Cairo, unidentified persons attacked the Muslim Brotherhood headquarters, which had been fortified with sandbags earlier. Staff inside said they had not broken in, Reuters news agency reports.
