Plant cell and growth words

Some of the most useful plant vocabulary describes what happens inside a cell or seed before a plant is visible above ground. Chlorophyll is the pigment that lets leaves capture sunlight, and photosynthesis is the process that turns that light into food. Germinate describes a seed's first stage of growth, when a root and shoot break through the seed coat and begin to develop.

Frequently asked questions

An annual completes its life cycle in one growing season and then dies, while a perennial regrows from its roots year after year.

What does deciduous mean?
