Time

There are two more things that plants need to live and grow which may seem pretty obvious to us. One of those things is time. Plants live, grow, flower, and die in different time frames. Annuals are plants that complete their life cycles in one growing season. Biennials need two growing seasons to complete their life cycles. A perennial is a plant that lives for three of more years. It may grow new stems if it is herbaceous, or it may just live for many years (trees.)

Room to Grow

And last but not least, plants must also have room to grow both above and below ground so they can carry out the process of making food for themselves. If plants do not have enough room to grow, they begin to compete with each other for resources like nutrients and water. The stronger plants will take the nutrients and the other plants will wither and die.

Unscramble the words below to find four things plants need that we learned about in this mission. Make sure to write these four things in the table in your Agronaut Log (Entry 17.)
