Who Am I?
I am the haploid generation that produces gametes.
Gametophyte
Is a spore haploid or diploid?
Haploid
Which flower structure produces pollen?
Stamen
What is the male gametophyte of seed plants?
Pollen
A plant spreads horizontally and produces new upright shoots. What type of reproduction is occurring?
Vegetative reproduction
I am the diploid generation that produces haploid spores through meiosis.
Sporophytes
Which process produces haploid spores in the sporophyte?
Meiosis
Which flower structure protects the ovules?
Carpel
What structure carries the male gametes to the egg after pollination?
Pollen tube
A plant produces seeds without fertilization. What process occurred?
Apomixis
I am a tough covering that protects spores from environmental stresses like drying and UV radiation.
Sporopollenen
Which generation is dominant in bryophytes?
Gametophyte
Put these flower whorls in order from outside → inside: carpels, petals, sepals, stamens.
Sepals → Petals → Stamens → Carpels
Name one advantage seeds have over spores.
More stored resources OR dormancy
A plant produces flowers with nectar, bright petals, and a strong scent. What function are these traits most likely serving?
Attracting animal pollinators
I allow plants to produce seeds without fertilization, resulting in offspring genetically identical to the parent.
Apomixis
Both mosses and ferns have swimming sperm. What environmental resource is therefore important for their reproduction?
Water
What flower structure develops into the fruit?
Ovary
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.
A plant's pollen cannot successfully fertilize its own ovules. What reproductive mechanism does this describe?
Self-incompatibility
am a structure containing the female gametophyte, and after fertilization I develop into a seed. Who am I?
Ovule
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.
Angiosperms undergo a process that produces both a diploid zygote and triploid endosperm. Name the process.
Double fertilization
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
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.
