Answer 2

Answer:

C - organs

Explanation:

In biology, an organ is a group of tissues that perform a specific function or group of functions. Plant organs can be divided into vegetative and reproductive. Plant vegetative organs are root, stem and leaf, while reproductive organs are flower, seed and fruit.

Vegetative organs are essential for maintaining a plant's life (they form vital functions such as photosynthesis), while reproductive organs are essential for reproduction. But if there is asexual vegetative reproduction, the vegetative organs are those that create the new generation of plants.
