Gymno vs. Angio
These plants are often called "naked seeds" because they don't produce flowers or fruits.
gymnosperms
A monocot gets its name because its embryo has only one of these "seed leaves."
cotyledon
These plants complete their entire life cycle—from seed to flower to death—in just one growing season.
Annuals
These are the two main "tubes" in vascular plants used to transport water and food.
Xylem and Phloem
This group represents the vast majority of all living plant species and reproduces using flowers.
Angiosperms
If you see a flower with petals in multiples of 4 or 5, it likely belongs to this class.
Dicot
These "hardy" plants live for many years, often blooming every spring or summer.
Perennials
Unlike gymnosperms and angiosperms, mosses and liverworts lack vascular tissue and are called this.
Non-vascular plants
This specific structure in an angiosperm develops into a fruit after fertilization
ovary
Monocots typically have this type of leaf vein pattern, commonly seen in grasses.
parallel
This type of plant takes two years to complete its cycle, usually growing leaves the first year and flowers the second.
Biennials
This group of vascular plants doesn't use seeds at all, relying on spores instead (think ferns).
Seedless vascular plants
While angiosperms use flowers, most gymnosperms use these woody structures to house their seeds.
cones or strobili
In a Dicot stem, the vascular bundles (xylem and phloem) are arranged in this geometric shape.
rings
Carrots and foxgloves are common examples of this 2-year life cycle group
Biennials
This waxy coating on leaves helps plants retain water and is a key adaptation for living on land.
cuticle
This is the primary method of pollination for most gymnosperms, unlike many angiosperms that rely on insects.
Wind
This type of root system, featuring one deep main root, is a hallmark of Dicots
taproots
This term describes the "resting" state a seed enters to survive unfavorable conditions before germinating.
dormancy
This process, alternating between a multicellular haploid stage and a multicellular diploid stage, defines the plant life cycle
