Centrioles are found only in the male gametes of specific plant groups, not in all plants.
According to the provided reference, centrioles are not typically found in higher plants like conifers (Pinophyta) or flowering plants (angiosperms). Instead, they are specifically present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo.
Here's a breakdown:
-
Plants without Centrioles:
- Conifers (Pinophyta)
- Flowering plants (Angiosperms)
-
Plants with Centrioles (only in male gametes):
- Charophytes
- Bryophytes
- Seedless Vascular Plants
- Cycads
- Ginkgo
Therefore, centrioles in plants are restricted to specific groups and even then, only found in the male gametes.
