Are egg cells, located in the ovary, female or male reproductive cells?

female

20

What is the stalklike structure that connects the ovary to the tip of the pistil?

style

21

What is the tip of the pistil called?

The stigma

22

What does a complete flower contain?

sepals, petals, stamens, and pistils

23

What does an incomplete flower lack?

28

What is any plant on which both staminate and pistillate flowers are produced in the same plant?

monoecious

29

What is any plant that produce staminate and pistillate flowers but the two types of flowers are on separate plants?

34

What is the ovary called when it is fully ripened?

A fruit

35

What is the transfer of pollen from the anther to the stigma portion of a pistil called?

pollination

36

what type of pollination occurs within the same flower?

self-pollintion

37

What type of pollination occurs when the pollen from an anther of one plant is transferred to a stigma of a flower on another plant?

cross-pollination

38

What is a sweet-tasting, watery liquid produced by plants?

nectar.

39

What is the process called in which a sperm cell brought by a pollen grain fuses with the egg cell within the ovule?

What are the sperm and egg cells referred to as?

gametes (reproductive cells).

41

What type of reproduction occurs when a sperm and egg unite?
