Pio Review h. 21-25 May 07, 2011 Third and Ten, Part hapters 21-25 1 Lets see what we know so far...viruses are considered nonliving because F G they do not locomote they cannot reproduce independently their nucleic acid does not code for protein they are noncellular oth b and d are correct oth b and c are correct ll are correct 2 prophage occurs during the development of a lysogenic virus a provirus a lytic virus an enveloped virus 3 Which is not true of procaryotes? They are living cells. lack a nucleus. all are parasitic. are both archaea and bacteria. evolved early in the history of life. TH N!
Pio Review h. 21-25 May 07, 2011 How eucaryotic cells could have formed from procaryotic cells...nosymioti HYPOTHSIS 4 Red algae is: 5 rown algae is: phylum hlorophyta phylum Rhodophyta phylum Rhizopoda phylum Phaeophyta phylum iliophora phylum hlorophyta phylum Rhodophyta phylum Rhizopoda phylum Phaeophyta phylum iliophora 6 Green algae is: phylum hlorophyta phylum Rhodophyta phylum Rhizopoda phylum Phaeophyta phylum iliophora 7 Which is a false statement? Only heterotrophic and not photosynthetic protists are flagellated. mong protozoans, sporozoans are symbiotic. mong protists, the haploid cycle is common. iliates exchange genetic material during conjugation. Slime molds have an amoeboid stage.
Pio Review h. 21-25 May 07, 2011 8 ll are correct about brown algae except that they range in size from small to large. are a type of seaweed. live on land. are photosynthetic. are usually multicellular. Need textbook to see clearly, p. 401 9 uring sexual reproduction, the zygospore fungi produce an ascus a basidium a sporangium a conidiophore an independent film 10 n organism that OMPOSS remains is most likely to use which mode of nutrition? (MP) parasitic saprotrophic ingestion chemosynthesis 11 The taxonomy of fungi is based on sexual reproductive structures shape of the sporocarp mode of nutrition type of cell wall level or organization
Pio Review h. 21-25 May 07, 2011 12 Which statement is incorrect? Some fungi are parasitic, especially on plants, and others are mutualistic with plant roots and algae. The cell walls of fungi contain chitin. Following nuclear fusion, zygotic meiosis occurs during the production of spores. Lichens are an association between a fungus and a bacterium or alga. Step 2: Vascular tissues evolved for the purpose of transporting water This is the first step in evolution, and the characteristic that separates plants from the algae... Step 3: Seeds evolved to contain the embryo and stored organic nutrients within a protective coat. 13 Put the following in the correct order of evolution... 4th VNT: evolution of the flower...reproductive structure that attracts pollinators and gave rise to fruits that contain the seeds. seed, fruit, vascular tissue, protected embryo vascular tissue, protected embryo, seeds, fruit protected embryo, vascular tissue, fruit, seeds protected embryo, vascular tissue, seeds, fruits
Pio Review h. 21-25 May 07, 2011 14 Spores develop into the sporophyte. True False 15 Gametophytes form haploid gametes. True False s plants moved onto land the gametopytes become more reduced... SIS TH VOLUTION OF TH IG FOUR: protected embryo, vascular tissue, seeds and fruit...plants needed other adaptations to survive on land... RYOPHYTS MOIST HITTS LK TRU ROOTS, STMS & LVS SMLL Leaves needed to develop a protective waxy cuticle to prevent dessication and openings in those leaves to allow for gas exchange, stomata!

Pio Review h. 21-25 May 07, 2011 18 Which of these pairs is mismatched? anther--produces microspores carpels--produces pollen ovule--becomes seed ovary--becomes fruit flower--reproductive structure 19 SHOOTS R GNRLLY FOUN OV GROUN N ROOTS LOW GROUN. True False 20 Which of these is an incorrect contrast between monocots (stated first) and eudicots (stated second)? 1 cotyledon - 2 cotyledons leaf veins parallel - net veined vascular bundles in rings - vascular bundles scattered flower parts in 3's - flower parts in 4's and 5's ll of these are correct contrasts. 21 Which of these cells in a plant is apt to be nonliving? 22 Which of these types of cells is most likely to divide? parenchyma parenchyma collenchyma meristem sclerenchyma epidermis apical meristem xylem ll of these are correct. sclerenchyma
