The answer to this question

- Spores occur underneath the leaves - PTERIDOPHYTES

- cones contain the seeds - GYMNOSPERMS

- absorbs nutrients through diffusion and osmosis - BRYOPHYTES

- ovary encases the seeds - ANGIOSPERMS

Explanation:

Plants are a very diverse group of living organisms. Each plant group has its own unique characteristics that distinguishes it from other groups. Bryophytes and pteridophytes are considered as lower plants because of their primitive features while gymnosperms and angiosperms are considered as higher plants because of their advanced features. The prominent characteristics of each plant group according to this question is as follows:

- PTERIDOPHYTES produce spores underneath their leaves.

- BRYOPHYTES absorbs nutrients through diffusion and osmosis since they lack true roots, stems and vascular tissues.

- GYMNOSPERMS bear their naked seeds on structures called cones or strobili.

- ANGIOSPERMS encases their seeds in ovaries of their flowers, which later develops into fruits.
