D. Seed dispersal

Answer 1

Coniferous plants like cacti and pine trees have thin, needle-like leaves for water storage and defense against herbivores.

Step-by-step explanation:

Coniferous plants like cacti and pine trees have thin, needle-like leaves for water storage and defense against herbivores. These leaves have a reduced surface area, sunken stomata, and a thick cuticle to minimize water loss. For example, cacti have leaves that are reduced to spines, which help conserve water in arid environments.
