This plant region contains rapidly dividing cells and thereby permits continuous growth.
What is apical meristem?
100
Someone might want to place a towel over this group of plant’s “indecent” seeds.
What is a gymnosperm?
100

What is a gametophore?
200
A single embryonic leaf is only one of the features of this group of seed plants.
What is a monocot?
200
Specialized sporophyte cells undergo this process when forming haploid spores.
What is meiosis?
200
Mitt Romney might be tempted to take a sip of tea made from plants in this gymnosperm genus.
What is Ephedra?
200
This derived trait of seed plants may have parts with names that change over time, but she’s all girl.
What is an ovule?
300
The green algae in this group are the closest living relatives of land plants.
What are the Charophytes?
300
This group of vascular land plants includes some of the largest and longest-lived organisms on earth.
What is the Coniferophyta?
300
The day after running a marathon, you might feel like the name for this cluster of sporangia!
What is sorus?
300
This plant species is the source of atropine, a drug that blocks muscarinc ACh receptors.
