Document Summary
Bio 1010 stems absorb, eater and minerals) and above ground (plant leaves obtain. Root system - root/taproot: anchor plants, absorb and transport minerals and water, and store food. Root hairs (tiny tubular projections at the roots tips) greatly increase the surface area for absorption. Root hairs are extensions from the epidermal cell. Made up of stems, leaves, and adaptations for reproduction(in angiosperms = flowers). Leaves are the main photosynthetic organ, but not the only. Buds - buds are undeveloped stem, there are two types of buds, Terminal bud or apical bud( is at the tip(apex) of the plant, where the plant is growing in length, it contains developing leaves, and compact series of nodes and internodes). In many plants this bud produces hormones inhibiting the growth of the axillary bud, this is known as apical dominance. Axillary bud one in each space between the leaf and stem. However when they are not dormant branching occurs.
