Certainly not. There are tons of unicellular organisms like amoeba and other protozoa that are quite nicely alive, but don't have any form of sexual reproduction, so don't come from an egg.

False. Look at amoeba, they just split. Look at plants such as orchids, tubers ensure they propagate. Look at plants that produce rhizomes, a little bit of the root will produce a seed bearing plant. Worms have been able to produce sexually reproductive worms after being cut in half by re-growing the other half of the body.

Depends what you mean. Normally one sex cell is larger because it contains a food source, and one is small and mobile. the large one is normally designated "egg", the small one "sperm". Of course, a lot of bacteria are simply a divided cell, and you can grow plants from cuttings.
