Think About It
100

I am the haploid generation that produces gametes. 

Gametophyte

100

Is a spore haploid or diploid?

Haploid

100

Which flower structure produces pollen?

Stamen

100

What is the male gametophyte of seed plants?

Pollen

100

A plant spreads horizontally and produces new upright shoots. What type of reproduction is occurring?

Vegetative reproduction

200

I am the diploid generation that produces haploid spores through meiosis. 

Sporophytes

200

Which process produces haploid spores in the sporophyte?

Meiosis

200

Which flower structure protects the ovules?

Carpel

200

What structure carries the male gametes to the egg after pollination?

Pollen tube

200

A plant produces seeds without fertilization. What process occurred? 

 Apomixis

300

I am a tough covering that protects spores from environmental stresses like drying and UV radiation. 

Sporopollenen

300

Which generation is dominant in bryophytes?

 Gametophyte

300

Put these flower whorls in order from outside → inside: carpels, petals, sepals, stamens.

Sepals → Petals → Stamens → Carpels

300

Name one advantage seeds have over spores.

 More stored resources OR dormancy

300

A plant produces flowers with nectar, bright petals, and a strong scent. What function are these traits most likely serving?

 Attracting animal pollinators

400

I allow plants to produce seeds without fertilization, resulting in offspring genetically identical to the parent.

Apomixis

400

 Both mosses and ferns have swimming sperm. What environmental resource is therefore important for their reproduction?

Water

400

What flower structure develops into the fruit?

Ovary

400

Why was the evolution of pollen important for reproduction on land?

It allows male gametes to reach the female reproductive structures without requiring a wet land surface.

400

A plant's pollen cannot successfully fertilize its own ovules. What reproductive mechanism does this describe?

Self-incompatibility

500

am a structure containing the female gametophyte, and after fertilization I develop into a seed. Who am I?

Ovule

500

A diploid plant produces a haploid cell by meiosis. Does that cell immediately need to fuse with another cell to continue the life cycle? Explain.

No. It is a spore and can undergo mitosis to form a multicellular gametophyte.

500

Angiosperms undergo a process that produces both a diploid zygote and triploid endosperm. Name the process.

Double fertilization

500

A seed lands in an environment that is temporarily too dry for growth. What seed adaptation allows it to delay development until conditions improve?

Dormancy

500

A self-incompatible plant is isolated from all genetically different members of its species. It can still perform apomixis. Can it reproduce, and would the offspring be genetically different from the parent?

Yes. It can reproduce through apomixis, and the offspring would be genetically identical to the parent.
