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...

Angiosperm A flowering plant which forms seeds inside a protective chamber called an ovary. annual a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. annulus an arc or a ring of specialized cells on the sporangium Anther the part of a stamen that contains the pollen. Antheridia Structures in plants that produce male gametes Antibiotics Drugs that block the growth and reproduction of bacteria

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...

Part A Angiosperms are most closely related to _____. - gymnosperms Correct: The branching pattern of the phylogenetic tree in the activity indicates that angiosperms are most closely related to gymnosperms. Part A During the Carboniferous period, forests consisting mainly of _____ produced vast quantities of organic matter, which was buried and later became coal. - ferns and other seedless plants Correct: These were the dominant plant types of the time. Part A In contrast to bryophytes...

Four major adaptations of evolution of plants correct answer: -evolution of vascular tissue -diversification of vascular plants about 400 MYA with spore production as a means of reproduction -origin of seed producing plants 360 MYA -evolution of flowering plants 130 MYA Plants are.. correct answer: -multicellular -eukaryotic -autotrophic -almost 300,000 species -evolved from green algae Bryophytes are correct answer: mosses, simplest plants, nonvascular; often include liverwort a...

BIOL 1P92 Final Exam Prep Questions Well Answered 100% Prokaryotes which plastids originated from - ANSWER Photosynthetic prokaryotic endosymbionts by non-photosynthetic eukaryotic hosts. Are protists monophyletic? - ANSWER Protists are not monophyletic, they are paraphyletic (includes single ancestor and some descendants). They contain organisms that are more closely related to members of other kingdoms than they are to other protists. Phytoplankton - ANSWER Microscopic photo...
