1 Plant Organs Roots & Stems
2 I. Roots A. F(x)s = grow underground 1. Absorb water & nutrients from soil 2. Anchor plant in the soil 3. Make hormones important for growth & development
3 I. Roots B. Structure 1. Root cap F(x) = protects apical meristem
4 I. Roots B. Structure 2. Root hairs F(x) = increase surface area for absorption
5 I. Roots B. Structure 3. Casparian Strip F(x) = *channel water & dissolved nutrients into vascular tissue *allow movement only into roots
6 beet carrot I. Roots C. Types of Roots 1. Taproots a. Large main root that can store food b. F(x) = absorption, anchoring E.g.
7 C. Types of Roots 2. Fibrous roots a. Numerous small roots b. Grow near surface c. F(x)= absorption, anchoring c. E.g. grass
8 C. Types of Roots 3. Prop or Adventitious roots a. Grow down to soil from stem, above ground b. F(x)s = support, absorption c. E.g. corn, banyon tree
9 C. Types of Roots 4. Aerial Roots a. Grow without soil, in air b. F(x) = absorb water from moist air c. E.g. orchids in tropical rainforest
10 A. F(x)s 1. Hold leaves up to sunlight 2. Transport water & nutrients from roots to leaves 3. Food storage in some plants
11 B. Stem Structures 1. Node place where one or more leaves are attached Note: At the point of attachment of each leaf, there is a lateral bud with an apical meristem capable of developing into a new shoot
12 B. Stem Structures 2. Internode part of stem between nodes
13 C. Specialized stems 1. Rhizome = horizontal underground stem 2. Tuber = Underground stem w/ buds Food storage E.g. potato, parsnip
14 C. Specialized stems 3. Bulb = large bud w/ layers Food storage Many edible E.g. onion, garlic
15 C. Specialized stems 4. Corm = Upright, thickened underground stem Food storage Not usually edible E.g. shamrock plant (Oxalis)
16 C. Specialized stems 5. Some plants almost all stem, no leaves E.g. cactus
17 D. Stem growth 1. Growth in Length only at tips of stems where new primary growth occurs via apical meristems 2. Growth in Circumference width via lateral meristems
18 E. Primary Growth in Stems 1. Vascular tissue arranged in vascular bundles 2. Dicots bundles in a ring around outside edge 3. Monocots bundles scattered throughout stem
19 Dicot stem CS Vascular bundles
20 E. Primary Growth in Stems 4. Pith center of the stem 5. Cortex ground tissue btwn. Vascular Bundles & epidermis Vascular bundle dicot monocot
21 F. Secondary Growth in Stems Which get wider year after year, monocots or dicots? DICOTS! **Most monocots have no secondary growth. 1. stem width in dicots due to cell in vascular cambium
22 2. Vascular Cambium arises in vascular bundle btwn. xylem & phloem 3. Cylinder formed by cambium, then secondary xylem inside, then secondary phloem on outside of cylinder
23 G. Woody Stems 1. Heartwood 2. Sapwood 3. Bark DRAW THIS!
24 G. Woody Stems 1. Heartwood Dark color Center of tree trunk Dead xylem, no longer transports water F(x) = support
25 G. Woody Stems 2. Sapwood Lighter in color Nearer to outside of tree trunk F(x) = transport (live xylem) Note: In a large diameter tree, heartwood gets wider, sapwood stays relatively same width
26 G. Woody Stems 3. Bark F(x) = protection Made of cork, cork cambium & phloem
27 H. Stem F(x)s 1. Phloem moves sugars a. Translocation sugars moved from source (photosynthesis in leaves) to sink (where they are stored) b. Products of Photosynthesis can move in? direction ANY
28 H. Stem F(x)s 1. Phloem moves sugars c. Pressure Flow Hypothesis i. Sugars PUMPED into sieve the source ii. Turgor = pressure increase due to water entering sieve tubes by osmosis
29
30 H. Stem F(x)s 2. Xylem moves water & nutrients a. Cohesion-Tension Theory combination of 3 processes: i. Transpiration ii. Cohesion iii. Adhesion
31 Transpiration In leaves, release of excess water to atmosphere Creates negative pressure in xylem Replacement water pulled from xylem Water enters roots to replace lost water
32 Cohesion Water molecules stick to each other & pull each other up narrow xylem tubes Water is a polar molecule, therefore Water molecules attract each other!
33 Adhesion Water molecules strongly attracted to xylem wall
34 b. Final words on water movement in plants i. Varies with time of day ii. Midday stomata open, rapid movement iii. Night stomata closed movement stops Exception: cacti stomata night Why? to minimize water loss
