Plant Quiz Review Sheet502539031877000Non-Vascular Plants - lack vascular tissues. Do not have true roots, stems or leaves. Non-vascular plants rely on the processes of osmosis and diffusion to get needed materials.Grow in moist environmentsLow to the groundExamples: mosses, liverworts47148752934200Vascular Plants - use vascular tissues. Vascular plants have xylem and phloem. These tube like structures are used to transport water, minerals, and sugar to different areas of the plant.Examples: all other plants – ferns, conifers (cone-bearing plants), flowering plants.Two kinds of Vascular Tissue: Xylem - transports water and minerals from the roots to the leavesPhloem - transports sugar molecules from the leaves to the stem/rootsPlants usually have a waxy, protective layer called a cuticle that holds in moisture. Gas exchange can occur through small openings in the leaves called stomata. right3302000There are three types of Vascular PlantsVascular seedless - Have stems, but no seeds. Reproduce with spores as seen on the backs of ferns. Examples: ferns, horsetails, club mossesright63500Gymnosperms - Usually produce seeds in cones.Rely on wind and water to transport pollen from male cone to female cone. Examples: conifers (pine trees), gingkoes, palms514350019621500Angiosperms - produce seeds and flowers. Most successful group of plants because insects (bees) carry their pollen from flower to flower.Seeds are enclosed in a fruit that can be carried from place to place.Includes most plants that we see.Examples: grasses, flowers, fruit-bearing treesPlant Processes: Tropism - a change in the growth of a plant in response to a stimuli. Plant growth in response to light is called phototropism. Plant growth in response to gravity is called gravitropism. Photosynthesis – takes place in the chloroplast using sunlight energy captured by the green pigment called chlorophyll. Reactants: carbon dioxide, water, sunlight. Products: glucose and oxygen. Cellular Respiration: Glucose and oxygen are broken down in the mitochondria to release stored energy in the form of ATP. Water and carbon dioxide are waste products. 546671530607000291401526670000Classify These Plants: (Very small) Non-vascularGymnospermVascular seedless ................
