Final answer:
The seeds in trees like pines and firs form in cones, with the female cones being specifically involved in the seed production process. otpion a is answer
Step-by-step explanation:
In trees such as pines and firs, the seeds form in cones. The correct answer to the question is A) Cones. Pines and firs are types of coniferous trees that undergo sexual reproduction by producing seeds within these cones. Conifers have both male and female cones, with the female cones being responsible for the production of seeds.
These seeds can be winged for wind dispersal or adapted for dispersal by animals, such as birds. Cones are essential for the reproductive cycle of conifers, which includes spore production, megaspore germination, egg production, fertilization, and seed development.
The cones are complex structures that consist of an axis with scales subtended by bracts. The female cones, often called 'pine cones', are the most recognized and take multiple years to develop fully.
Coniferous trees are well adapted to cold and dry climates, featuring needle-shaped leaves with a waxy cuticle to limit water loss and aid in surviving harsh weather conditions. In summary, the reproductive organ of pine and fir trees where the seeds are formed is the cone. otpion a is answer
