3. What plants need to survive: A. Sunlight—plants have adaptations to gather sunlight for photosynthesis B. Water and minerals—all cells require a constant supply of water. Minerals are absorbed along with water. C. Gas exchange—plants must exchange gases (oxygen and carbon dioxide) to perform photosynthesis D. Movement of water and nutrients— plants take up water and minerals with their roots, but make food in their leaves.

4. Plant Structures A. Leaves a) Used for photosynthesis b) Photosynthetic Equation: 6CO2 + 6H2O C6H12O6 + 6O2 c) Special structures Stomata—opening in leaf to allow gas exchange Cuticle—waxy covering to prevent water loss Guard cell—regulates opening of the stomata Cross Section of a Leaf Light Energy

B. Roots—are used for: a) Absorption of minerals and water b) Storage of starches c) Anchor to ground/soil d) 2 main types of roots: taproot—grow long and deep to reach water below the surface fibrous—branched root system that grows close to the surface

a) xylem—used to transport water UP b) phloem—used to transport food DOWN Exceptions- nonvascular plants Mosses- no transportation system, therefore, they are small and close to the ground C. Stems—are used for transportation (vascular plants)

5. Plant Responses—Tropisms A. Gravitropism—response to gravity Plants grow upwards out of the soil and the roots grow down B. Phototropism—response to light Plants grow towards a light source C. Thigmotropism—response to touch Plants that close up when touched Example: Climbing plants or vines that twist around any object they touch

D. Reproduction a) Flowers—contains the male and female sexual organs b) Cones—sexual c) Spores—asexual E. Seed—fertilized egg a) Fruit—mature ovary that contains one or more seeds

1. Adaptations—an inherited characteristic that increases an organism’s ability to survive and reproduce. A. How do adaptations occur? a) Mutations—sudden changes in the genetic code (DNA). b) KEY POINT: Beneficial mutations allow organisms the ability to adapt and therefore, survive and reproduce. Plant Adaptations for Survival and Reproduction

2. Adaptations for Survival A. Different environments: a) Desert plants—able to tolerate strong winds, daytime heat, and infrequent rainfall. Plants grow slowly Plants have a deep root system to gather water Plants have thick stems to store large amounts of water Plants have spines instead of large leaves to reduce water loss Example: Cactus b) Arctic Tundra Plants are low growing and small due to lack of nutrients

B. Carnivorous Plants—have specialized features for obtaining nutrition a) Pitcher Plant b) Venus Fly Trap

C. Defense Mechanisms a) Poisons—lethal when eaten b) Chemicals that act as insect hormones—disrupt normal growth and development c) Thorns/thistles—undesirable or hard to eat D. Leaf Adaptations—needle-like versus broad leaf

3. Adaptations for Reproduction A. Pollination—produces seeds by the transfer of pollen from male reproductive structure to female reproductive structure a) Carried out by animals (mainly insects and birds) that carry pollen from one flower to another Animals are attracted by bright colors, smell and nectar (food) b) Wind pollination—less efficient, relies on large numbers of spores
14

B. Seed Dispersal a) Animal Dispersal Fruits—provide nutrition for animals and helps plants spread seeds Burrs—get snagged on fur, carry seeds from one area to another b) Wind and Water Dispersal— lightweight seeds carried in the air or float on surface of water
