A seed with one embryonic seed leaf belongs to this class of angiosperms.
What is a monocot?
These plants complete their entire life cycle in one year or one growing season.
What are annuals?
This process uses sunlight to convert energy into food for the plant.
What is photosynthesis?
Cotton and linen are examples of plant products used to meet this basic human need.
What is clothing?
Pines, firs, spruces, redwoods, and ginkgoes belong to this plant group.
What are gymnosperms?
A seed with two embryonic seed leaves belongs to this class of angiosperms.

What is respiration?

What are netted veins?
These plants produce for more than two years or growing seasons.

Monocots usually have flower parts in multiples of this number, while dicots usually have flower parts in multiples of four or five.
What is three?
Perennials with soft stems that are killed by frost are classified as this type.
What are herbaceous perennials?
These pore-like openings on leaves allow gas exchange.
What are stomata?
