vertical, underground structure that anchors the plant in the soil
it takes in nutrients and water
some roots can serve as a storage structure
describe the shoot portion of a plant
branches, leaves, and flower are found here as well as axillary and terminal buds which form new branches, leaves, or flower
what do leaves do?
capture sunlight to convert carbon dioxide and water into cellulose
what is the main difference between monocots and eudicots?

eudicots have two cotyledon
what are some examples of dicots/eudicots?
maples, roses, African violets, daisies, sunflowers, carrots, cacti, water lilies, and cabbage
veins in leafs in eudicots vs monocots
eudicots: netlike (like on a regular leaf)
monocots: parallel (like on grass)
flower parts in eudicots vs monocots
eudicots: usually in multiples of four or five
monocots: usually in multiples of three
arrangement of primary vascular bundles in stem in edicts vs. monocots
eudicots: in a ring
monocots: scattered
arrangement of primary vascular bundles in root in edicts vs. monocots
eudicots: in a central cylinder
monocots: in a ring
what kind of plant has a taproot?
eudicots
ex. carrots and turnips
what are vascular bundles?
localized collections of phloem and xylem, the cells responsible for transporting nutrients and water, respectively thought the plant
