The image is a diagram of the life cycle of a terrestrial orchid. It is a black and white illustration that shows the different stages of the plant's life cycle.

The diagram is divided into three sections. The first section shows the plant with its leaves, stems, and roots. The second section shows a plant stem with a flower bud at the top. The third section shows two leaves, one on each side of the stem and the other on the other side. The plant stem is connected to a parent tuberoid, which is a type of tuberous plant. The mother tuberoid is responsible for the growth and development of the tuberoid. The tuberoid has a long, thin stem that extends from the top to the bottom of the image, and the mother tuberoids are responsible for releasing the tuberoids into the soil. The diagram also shows how the plant works, with each branch representing a different stage of growth. The background of the diagram is white, and there is text at the bottom that explains the purpose of each stage.
