was anyone gonna tell me that potatoes are stems or was I just supposed to read that in this textbook myself

★
Axillary bud - in angle between leaf and stem, can form lateral branch/thorn/flower

★
Apical bud - growing shoot tip

★
Nodes (points of leaf attachment) alternate with internodes

★
Stem - bears leaves and buds, elongates to maximize photosynthesis, elevates reproductive structures (to disperse pollen/fruit)

★
Root hairs (thin extensions of root epidermal cells) - increase SA for absorption

★
Holds topsoil in place, prevents soil erosion

★
Small roots arise from the stem (adventitious) → each forms lateral roots

★
Small plants → fibrous roots (thick mat of slender roots), primary root dies early

★
Lateral roots do absorption, while taproots provide support/storage

★
Tall, erect plants → taproot (1 main vertical root), develops from primary root
