Organization of the plant body Vascular Plants A. Vascular plants include plant organisms such as ferns, pine trees and flowering plants B. Vascular plants are plants having specialized tissues C. common mechanism for development and similar internal structure D. the vascular plant body II. Plant cells and tissues Meristems B. Tissues 1. Ground tissue system 2. Vascular tissue system 3. Dermal tissue system C. Within each tissue system there are either simple or complex tissue 1. Simple tissues 2. Complex tissues a. The vascular system b. the xylem c. Phloem d. The dermal tissue system e. Secretory tissues Terms Albuminous cells Companion cells Cork cambium (phellogen) Cork cells (phellem) Cortex Dermal tissue system Epidermis Fibers Ground meristem Guard cells Mersitem Mesophyll Parenchyma Periderm Phelloderm Pith Pits Primary meristem Primary phloem Primary xylem Procambium Protoderm Root Apical Meristem Root system Sclereids Sclerenchyma Secondary meristem Secondary phloem Secondary xylem Shoot system Sieve cells Sieve plate Sieve tubes and members Stomates Tracheids Trichomes Chapter 4 Lesson Objective/Homework 1. What is the role of meristematic cells and how do they differ from other cells? 2. Describe the characteristics of parenchyma, collenchyma and sclerenchyma cells. 3. How do simple and complex tissues differ? 4. How does the dermal tissue protect the plant? What is the basic structure of the dermal tissue system? 5. What are the 2 complex tissues that form the vascular system, and how do they differ structurally? What is the purpose of each one? 6. What are the purposes of the ground tissue system? 7. Compare and contrast vessel elements and tracheids. 8. How do water conducting cells differ from those that transport food? 9. Compare and contrast sieve tube members and sieve cells. 10. Describe the following meristems: root and shoot apical meristems; primary meristems (protoderm, ground meristem, procambium); and secondary meristems: (vascular cambium, cork cambium). Diagram where they would be in a tree. 11. Show in a diagram how SAM and RAM give rise to the 3 primary meristems, and how 3 primary meristems give rise to the primary tissue systems \P  BChVh5hm]hhDhP;>*hhDhhD>*hIhhDh9C h9CCJ.]O P  b T j & F zgdhD zgdI zgdhD$a$gd9Cgd9C  9 N U j t {   + 7 zgd5 zgdI7 A N a r WE=B zgd5gd5 zgd5BC2P/ =!v"#v$% Dp^ 2 0@P`p2( 0@P`p 0@P`p 0@P`p 0@P`p 0@P`p 0@P`p8XV~_HmH nH sH tH @`@ 5NormalOJQJ_HmH sH tH DA D Default Paragraph FontRiR  Table Normal4 l4a (k (No List PK![Content_Types].xmlj0Eжr(΢Iw},-j4 wP-t#bΙ{UTU^hd}㨫)*1P' ^W0)T9<l#$yi};~@(Hu* Dנz/0ǰ $ X3aZ,D0j~3߶b~i>3\`?/[G\!-Rk.sԻ..a濭?PK!֧6 _rels/.relsj0 }Q%v/C/}(h"O = C?hv=Ʌ%[xp{۵_Pѣ<1H0ORBdJE4b$q_6LR7`0̞O,En7Lib/SeеPK!kytheme/theme/themeManager.xml M @}w7c(EbˮCAǠҟ7՛K Y, e.|,H,lxɴIsQ}#Ր ֵ+!,^$j=GW)E+& 8PK!Ptheme/theme/theme1.xmlYOo6w toc'vuر-MniP@I}úama[إ4:lЯGRX^6؊>$ !)O^rC$y@/yH*񄴽)޵߻UDb`}"qۋJחX^)I`nEp)liV[]1M<OP6r=zgbIguSebORD۫qu gZo~ٺlAplxpT0+[}`jzAV2Fi@qv֬5\|ʜ̭NleXdsjcs7f W+Ն7`g ȘJj|h(KD- dXiJ؇(x$( :;˹!
