Plant Groups & Classes
This broad group of plants produces seeds that are unprotected by an ovary or fruit, often referred to as having "naked seeds."
A: What are gymnosperms?
These are plants that complete their entire life cycle—from germination to seed production—within a single growing season.
A: What are annuals?
This structure, also known as a seed leaf, is the first leaf or set of leaves to emerge from a germinating seed.
What is a cotyledon?
This is the specific number of cotyledons, or seed leaves, found in a monocot embryo.
What is one?
This major plant group relies on flowers to attract pollinators and fruits to disperse its seeds.
What are angiosperms?
This group consists of flowering plants that produce seeds enclosed within a protective fruit or ovary.
What are angiosperms?
These plants require two growing seasons to complete their life cycle, typically growing leaves the first year and flowering the second.
What are biennials?
While monocots have a fibrous root system, dicots typically develop this type of deep, central root system.
What is a taproot?
If you look at a leaf and see a network of branched or net-like veins, the plant belongs to this specific class.
What is a dicot (or dicotyledon)?
Pine trees, cycads, and ginkgoes belong to this group, which relies primarily on the wind for pollination.
What are gymnosperms?
This class of flowering plants is characterized by seeds containing a single cotyledon, parallel leaf veins, and floral parts in multiples of three.
A: What are monocots?
These plants live for three or more years, often blooming every year once they reach maturity.
What are perennials?
In gymnosperms, this structure is typically used instead of a flower to house reproductive organs and seeds.
What is a cone?
This class of flowering plants typically features floral parts, such as petals or stamens, arranged in multiples of three.
What are monocots?
In gymnosperms, reproductive structures are housed in these Woody or fleshy structures instead of flowers.
What are cones?
This class of flowering plants features seeds with two cotyledons, net-like leaf veins, and floral parts typically in multiples of four or five.
A: What are dicots?
Carrots, onions, and foxgloves are common examples of this specific life cycle type.
What are biennials?
This vascular tissue distribution is highly organized in a ring within a dicot stem, but scattered throughout a monocot stem.
What are vascular bundles?
Unlike dicots which have a primary taproot, monocots are characterized by this web-like type of root system.
What is a fibrous root system?
This structural layer of the ovary develops into a fruit in angiosperms, but is completely absent in gymnosperms.
What is the protective ovary wall (or carpel)?
This is the specific plant group to which conifers, cycads, and ginkgos belong.
A: What are gymnosperms?
Marigolds, watermelons, and corn are examples of this short-lived life cycle type.
What are annuals?
This underground structure allows many herbaceous perennials to survive harsh winters and regrow year after year.
What is a bulb (or rhizome/tuber)?
Inside the stem of a dicot, the vascular bundles (xylem and phloem) are arranged in this highly organized geometric pattern.
What is a ring?
Angiosperms uniquely undergo this complex fertilization process, where one sperm fertilizes the egg and another forms the endosperm nutrient tissue.
What is double fertilization?
