Q

ovule

A

immature seeds

38
Q

receptacle

A

holds flower

39
Q

Pollen tube

A

How sperm travels to ovary and is built by pollen (many in one flower pistil because a new one is made with each pollen grain that lands on stigma & it drills a pollen tube all the way from the stigma, down the style, to the ovary for fertilization)
