39.2 Plant hormones 131095 SunHa Lee cytokinins - 2) apical dominance Apical dominance: ability of the apical bud to suppress the development of axillary buds Direct inhibition hypothesis: auxin & cytokinins act antagonistically in regulating axillary bud growth - auxin: sent from apical bud, directly inhibits axillary growth - cytokinins: sent from roots, signals axillary growth Ratio of auxin and cytokinins is important 2) apical dominance Apical bud removed: no inhibition of axillary buds, more lateral branches Auxin added: lateral bud growth repressed Overload of cytokinins: more lateral branches, bushier 3) anti-aging effects Slow aging - inhibit protein breakdown - stimulate RNA and protein synthesis - mobilize nutrients from nearby tissues

Biology 225: Chapter 35 Q: What are the two systems of a plant and what are they responsible for? A: The Root System (roots) is responsible for absorbing water and minerals from the ground whereas the shoot system (the stems and leaves) is responsible for obtaining light and carbon dioxide from above the ground. Both systems cannot live without the other; the roots require sugar produced by photosynthesis which comes from the shoot system and the shoots require the water and minerals absorbed by the root system for survival. Q: What is the difference between an Angiosperm and a Gymnosperm? A: Vascular Plants with Seeds Gymnosperms Angiosperms

Xylem

Vascular Tissue and Transport VASCULAR TISSUE & TRANSPORT Plants rely on specialized tissue, called vascular tissue, to transport water, nutrients, and the products of photosynthesis around the plant. The two types of vascular tissue are: xylem (zy-lum) phloem Water Transport Xylem - Transports water from the roots up to the rest of the plant in one way flow. Tracheids - Hollow cell in xylem with thick cell walls that resist turgor pressure Water Transport Water rises through the thin tubes by a process called capillary action (cohesion of water molecules and adhesion to solid surface). The thinner the tube, the higher the water will rise.

Plant

Classification Multicellular Eukaryote Have cell walls made of cellulose Carry out photosynthesis AND respiration Most are autotrophs A few are parasites (live on living organisms) or saprobes (live on dead organisms) Store energy as starch (carbohydrates) Sunlight Water Minerals Gas Exchange (CO2 in: O2 and some CO2 out) Transport of water and nutrients throughout the plant body Remember Photosynthesis: 6H2O + 6CO2 ? C6H12O6 + 6O2 (water + carbon dioxide + sunlight ? glucose + oxygen) Plants life cycles have two alternating phases known as alternation of generations: A diploid (2N) phase known as the sporophyte (spore producing plant). A haploid (N) phase known as the gametophyte (gamete producing plant)

Chris Schink Biology Vocab Chapter 29 Parenchyma- In higher plants, the fundamental tissue that is composed of thin walled living cells that function in photosynthesis and storage. Collenchyma- A group of elongated, thick walled plant cells that support the growth of leaves and stems. Sclerenchyma- A type of plant tissue composed of cells that have thickened secondary walls that function in plant support. Epidermis- The outer layer of cells of a plant or animal. Cuticle- A waxy or fatty watertight layer on the external wall of epidermal cells. Tracheid- A thick-walled cylindrical cell with tapered ends that is found in xylem and that provides support and conducts water and nutrients. Pit- In plants, the thin, porous areas of a tracheid cell wall.

3/14/13 8:53 AM Three main structures: Roots Tap root lateral roots arises from pericycle outer most layer in vascular cylinder generally penetrate deeply ground water not close to the surface eudicots Fibrous roots don?t penetrate deeply shallow soil or a lot of rain fall monocots Root hairs increases surface area most of the absorption occurs here Stems Nodes point at which leaves are attached Internodes the sections between the nodes Auxiliary bud structure that forms a lateral root (branch) growing auxiliary bud means lateral shoot Apical bud (terminal) inhibits growth apical dominance inhibits the auxiliary buds if sunlight is more intense on one side, the auxiliary buds break dormancy Stems with additional functions such as food storage or asexual reproductions
