3 basic organs: roots, stems, leaves → root system and shoot system

Report

Roots depend on photosynthates from the shoot system, and the shoot system depends on water/minerals from the roots

Root - anchors vascular plant to the soil, absorbs minerals/water, stores carbs

Primary root - originates in seed embryo, first to emerge in germination
Branches to form lateral roots

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

Report

Voltie Posted 5 years ago ( 2019/08/13 03:59:31 )

Lateral roots do absorption, while taproots provide support/storage

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

Report

Voltie Posted 5 years ago ( 2019/08/13 03:59:48 )

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

Holds topsoil in place, prevents soil erosion

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

Report

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

Report

Nodes (points of leaf attachment) alternate with internodes

Apical bud - growing shoot tip

Report

Voltie Posted 5 years ago ( 2019/08/13 04:05:09 )

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

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

Leaves - main photosynthetic organ, exchange gases, dissipate heat, fend off predators
