This is a bit of a trick question! It depends on what you're asking about. Here are a few possibilities:

* Oxygen and Glucose: Plants produce oxygen as a byproduct of photosynthesis and glucose as a source of energy.

* Flowers and Fruit: Some plants produce flowers to attract pollinators, and then fruit to protect and disperse seeds.

* Leaves and Stems: These are basic parts of the plant that contribute to its growth and survival.
