Answer:

Ovule is absent in Gymnosperms.

Explanation:

ovule is usually not found in Gymnosperms. Conifers, cycads, gingko, and other plants that produce seeds are included in the group of plants known as gymnosperms. Gymnosperms are frequently referred to as "bare seed plants" because they lack an ovary wall, leaving their ovules exposed or unprotected.

Plants known as gymnosperms have seeds but no blooms. These vascular land plants bear naked seeds and are land plants. The ovary does not surround the ovules. Consequently, gymnosperms don't have blooms.

Gymnosperms are part of the Plantae kingdom and the Embryophyta subkingdom. They appeared to have started during the Paleozoic era, or around 390 million years ago, according to the fossil evidence.

In contrast to angiosperms, gymnosperms are plants that the ovules are not encased within the ovary wall. It continues to be exposed both before and after fertilisation as well as before becoming a seed. Gymnosperm stems can have branches or be unbranched. The rate of water loss in these plants is slowed down by their thick cuticle, needle-like leaves, and recessed stomata.
