charophytes - (aquatic) green algae land plants evolved from 3 key traits land plants share with charophytes - 1. rings of cellulose-synthesizing proteins embedded in plasma membrane 2. formation of a phragmoplast (helps form cell wall) 3. structure of flagellated sperm (not all will have this) adaptations enabling plants' move to land: why? - 1. CO2 2. sunlight 3. soil- nutrients 4. fewer predators/pathogens (never been seen before) adaptations enabling plants' move to land: problems...

Land Plants Complex multicellular organism that range in size from minute to MASSIVE. Adaptations of this type of plant include anatomical, physiological, and reproductive features. Waxy Cuticle Covers aerial portions of a plant, protects against water loss. Resides ON TOP of the epidermis. Stomata Used for gas exchanged, required for photosynthesis. Guard Cells surround this and can open or close it depending on environmental/chemical interactions. Antheridia Gametangia that produce SPER...

Biology 104: Plant Exam questions with correct answers What are the characteristics of a plant? -Correct Answer-A multicellular, eukaryotic, autotrophic organism with a cell wall (cellulose), performs photosynthesis, store starch, non mobile, alternation of generations, reproductive protection tissue From what organism did plants evolve? -Correct Answer-Charophytes (green algae) What are the adaptations of plants to life on land? -Correct Answer-the need for a constant supply of water (ro...

Flowers - The reproductive structure in plants Double Fertilization - One sperm unites with an egg, forming a diploid zygote, and the other unites with polar nuclei, forming a triploid endosperm nucleus. Eudicotyledones (Eudicots) - -Two cotyledons -Flowering parts in four of fives or multiples of four or five -Pollen grain with three pores -woody or herbaceous -usually net venation -vascular bundles in a ring -taproot system Alteration of generations - The alteration of two or more di...

What are the key characteristics of plants? Answer> - Composed of one or more eukaryote cell(s) - Cell wall composed of cellulose - Chlorophyll in chloroplast How do plants acquire energy? Answer> By autotrophy (photosynthesis) How do plants acquire nutrients? Answer> Absorbed from the environment (Nitrogen and Phosphorus) How do plants produce ATP? Answer> Aerobic cellular respiration What plant is an exception? Why? Answer> Ghost plants - Lacks chlorophyll, and is pa...

List four groups of land plants, and able to mark their traits on a phylogeny. - ANSWER 1. nonvascular (mosses) : diverged from green algae 2. seedless vascular (ferns) : adaptive radiations in Devonian & Carboniferous 3. seed plants : recent adaptive radiation, dominate planet! -gymnofers (pine cones) : conifers -angiosperms : flowering plants (DOMINANT) Explain why branching in plants is important. - ANSWER -more reproductive potential, more flowers on a branched tree -more photosynt...
