Ответ:

пыльца ➪ спермии

Объяснение:

Каждая мужская шишка состоит из оси, на которой находятся чешуйки.

На нижней стороне каждой чешуйке располагаются по 2 пыльцевых мешочка, в которых созревает пыльца и в них чуть позднее образуются мужские половые клетки — спермии.

cvladim85: спасибо большое:)

superlimb0: обращайся ♡
