Terms/Definitions

100

These flowers have either stamens or carpels

Imperfect flowers

200

The transfer of pollen grains from the anther to the carpel

Pollination

300

The generation that occupies the largest portion of the life cycle

dominant generation

400

a life cycle in which there is both a multicellular diploid and a multicellular haploid form

Alternation of generations

500

A process that requires two sperm to fuse with two other cells

Double fertilization

Flowers and parts (you will also label parts of a flower)

100

These are flowers with both stamens and carpels

Perfect Flowers

200

This part of a flower protects the sexual organs as they form

Sepal

300

This part of a flower forms and releases pollen grains

Anther

400

This part of a flower holds the embryo sac

Ovule

500

This part of a flower catches pollen grains

Stigma

Spreading seeds

100

Before germination, this part of a seed feeds the embryo by either being the food source or transferring food from the endosperm to the embryo.

Cotyledon

200

A plant produces this to allow for the dispersal of seeds away from the parent.

fruit

300

Three ways in which pollen is transferred from the stamens of one flower to the carpels of another may include:

wind, bees, beetles, birds, moths, butterflies

400

Which has more cells prior to fertilization, a pollen grain or an embryo sac?

An embryo sac has more cells

500

In an angiosperm, double fertilization produces these two things.

a diploid zygote and an endosperm

Plant diversity

100

 The most recognizable stage in mosses is this.

The gametophyte generation

200

Pteridophytes can be identified by this tissue.

Vascular tissue

300

A tree with seed cones and pollen cones belongs to this group of plants in the phylum coniferophyta.

Gymnosperms
