The absence of a fruit covering the seed is a characteristic feature of gymnosperms, a group of seed-producing plants.

Answer : 3. "cryptogams"
Explanation :
The plants that never produce flowers are called "cryptogams." Cryptogams include plants such as ferns, mosses, liverworts, and algae. Unlike flowering plants (angiosperms), which reproduce through seeds enclosed within flowers, cryptogams reproduce through spores and do not produce true flowers. Cryptogams are considered more primitive in evolutionary terms compared to angiosperms, which are the most dominant group of plants on Earth today.

Answer : 2. "epithelial tissue"
Explanation :
Epithelial tissue plays a crucial role in wound healing. When the skin is wounded, epithelial cells at the edges of the wound multiply and migrate to cover the wound, forming a protective layer. This process is essential for the initial sealing of the wound and is one of the early stages in the overall wound healing process. Epithelial tissue helps in closing the wound and restoring the skin's integrity.
