Yes, because the food will cook best in a preheated oven.
Microwave ovens do not need to preheat, it is not good to run them without food inside. This can damage the oven.
To preheat means to bring up to the required temperature before using, so for an oven, turn it on and allow time for it to come up to the required temperature before putting in the food. Most ovens have an indicator light on the front panel that will switch off when the oven has reached the set temperature.
You would preheat the oven for an eggless chocolate cake in the same way you would preheat the oven for any other type of cake: turn the oven on, set the thermostat to the required temperature, then wait for the oven to reach that temperature.

Preheat in oven terms means that you turn the oven on and without putting anything in it let the oven get to the temp you need for the item you are baking
Preheat your oven before putting the food in it. Be patient and cook at lower temperatures. High heat can dry out the outside of your food long before the inside is cooked to the the desired doneness. Covering the food also helps slow the outside browning if you need to cook it in a hurry and at higher temperatures.
You should always preheat equipment such as ovens and fryers so that they are cooking at the correct temperature when the food is placed in it. This will ensure proper even cooking of the food. If you are using an electric stove, you may want to preheat your pans because it takes so long for electric heating elements to come to temperature, compared to gas burners. If your recipe says to cooks at medium for 15 minutes, you won't be at "medium" on an electric stove for several of those 15 minutes unless you preheat.
