INTRUCTIONAL DESIGN

School Class Subject Material Time Allocation

: Junior High School : VIII (Eight) : SAINS BIOLOGY : 1 x 40 minutes (1 time of meeting)

Competence Standard 2. To understand the system in the plant life. Basic Competence 2.3 To identify kinds of plant motion. Indicator 1. To describe kinds of plant motion 2. To explain the distinguish of nasty motion, tropism motion and taxis motion. A. Learning Purpose The student can: 1. To explain the mechanism of plant motion. 2. To mention the stimulate that influence plant motion. 3. To explain the distinguish of hygroscopes motion and esionom motion. 4. To explain the meaning of nasty motion, tropism motion and taxis motion. 5. To mention the distinguish of nasty motion, tropism motion and taxis motion. B. Learning Materials Plant Motion Motion is one of the respond shape of organism toward the stimulate. The stimulate can see from external or from internal the body self. In reality the plant can do the motion although some of them not conspicuous. For example the plant can conspicuous the motion like, putrid malu (Mimosa pudica) which like grow in the road. When, the leaf we touch so the leaf that presence will direct to close. That is name irritability, where the plant can receive and respond the stimulate. Each organism can move although very slowly because one characteristics of organism is move. The plant motion can caused by the presence of stimulating/stimulus which come from external. The motion distance can approach or too can remove the stimulus. Kinds of Plant Motion : 1. Hygroscopes motion Is the motion that caused by the influence growth of water capacity. Example : - break of the castor fruit (Ricinus communis) - opened the annulus in sporangium (spore box) in Pteridophyta plants - opened and closed the sporangium in moss plant by peristom

2. Ethionom motion Is the plant motion which caused by the external stimulate. Based on the characteristic of ethionom motion can distinguished become : a. Trophy or tropism is the body part motion of plant to the stimulate distance (positive trophy) and remove the stimulate (negative trophy), include : - Phototrophy (heliotrophy) : is the stem motion to the sun direction. - Geotrophy : is the root grow motion to the center of world (gravity). - Hidrotrophy : is the body grow to the water direction. - Tigmotrophy (haptotrophy) : is the part plant of bend motion as the offending result. Example : to twist the tip of stem and sucker of Cucurbitaceae. - Chemotrophy : is the motion because the chemical stimulate. Example : the roots to the food matter or remove the toxic. b. Taxis Is the move of place by the plant (has one cell) or the plant part can approach or remove the direction come of stimulate, include: - Phototaxis : the stimulate is shine example : The chloroplast move to the cell side which get to the sun shine. Euglena viridis always move to the place which touched of the shine Moss spore of Pilobolus will move to the place which touched of the shine - Chemotaxis : the stimulate is chemical matter example : Aerob bacteria always grouping in the place which has many oxygen Spermatozoid move to the egg cell in the moss fertilization. The stimulating is sugar matter or protein. c. Nasty Is the body part motion of plant as the respond to the stimulating from the external. Nasty motion caused by the turgid pressure exchange in the tissue, include : - Seismonasty : is the result of offending motion Example : closed motion of putri malu (Mimosa pudica) leaf, when touched. - Nictinasty : is the sleep motion as the dark stimulating. Example : closed motion the compound leaf in petai cina in the night time. - Photonasty : the stimulate is shine Example : like varicose pukul empat (Mirabilis jalapa) flower in the afternoon - Thermonasty : varicose motion of tulip flower because the temperature stimulating - Complex nasty 3. Endonom or autonom motion This motion is the plant motion that not caused by the external stimulating. May be the motion was happened by the stimulate from the self of the plant. Example : cytoplasm cell motion of Hydrilla and onion. C. Learning Method

1 . Model 2. Method

: - Direct Instruction (DI) - Cooperative Learning : - Group discussion

D. The Steps of Activity THE FIRST MEETING a. Introduction Activity Motivation and Apperception: - What happened if we touch the leaf of putrid malu plant? Knowledge Preterm: - What the meaning of hygroscopes motion? - What the meaning of nasty motion? b. Basic Activity Teacher leading the student in the group formation. Student (leaded by teacher) discussing some kinds of plant motion. Student (leaded by teacher) discussing the mechanism of plant motion. Student in the each group discussing about the meaning of irritability Vice from each group asked to mention the stimulating which influence the plant motion. Student discussing with the group about the distinguish of hygroscopes motion and esionom motion. Vice from each group asked to mention the example of hygroscopes motion and esionom motion. Student presentation the group discussion result with classical. Teacher responding the group discussion result of student and giving the true information. Student (leaded by teacher) observing some kinds of plant for knowing the motion which done, result from the stimulating which gave. Student in the each group discussing about the meaning of nasty motion, tropism motion, and taxis motion. Vice from each group asked to mention the example of nasty motion, tropism motion, and taxis motion. Student presentation the group discussion result with classical. Teacher responding the group discussion result of student and giving the true information. c. Last Activity Teacher giving appreciation to the group with the good job. Student (leaded by teacher) discussing for make the bounds. Teacher giving homework like task exercise. E. Study Source a. The book of Biology Sains Jl.2 (Esis) page 191-200. b. Chart

F. Evaluation of Study Result a. Evaluation Technique : - Written test b. Instrument Form: - Multiple Choice test - Essay test c. Instrumen Example: - Multiple Choice test Grow the root to the below is .... motion a. geotrophy c. nasty b. phototrophy d. trophy - Essay Test Make table distinguish between tropism motion and nasty tropism, then give the examples. . th Makassar, March 2010 Known, Headmaster Teacher Subject Material

RENCANA PELAKSANAAN PEMBELAJARAN ( RPP )

Sekolah Kelas Mata Pelajaran Alokasi Waktu

: SMP : VIII (Delapan) : IPA BIOLOGI : 1 x 45 menit (1 x pertemuan)

Standar Kompetensi 2. Memahami sistem dalam kehidupan tumbuhan. Kompetensi Dasar 2.3 Mengidentifikasi macam-macam gerak pada tumbuhan. Indikator 1. Mendeskripsikan macam-macam gerak pada tumbuhan. 2. Menjelaskan perbedaan gerak nasty, gerak tropisme dan gerak taksis. A. Tujuan Pembelajaran Peserta didik dapat: 6. Menjelaskan mekanisme gerak pada tumbuhan. 7. Menyebutkan rangsangan yang mempengaruhi terjadinya gerak pada tumbuhan. 8. Menjelaskan perbedaan gerak higroskopis dan gerak esionom. 9. Menjelaskan pengertian gerak nasti, gerak tropisme, dan gerak taksis. 10. Menyebutkan contoh gerak nasti, gerak tropisme, dan gerak taksis. B. Materi Pembelajaran Gerak pada Tumbuhan Gerak merupakan salah satu bentuk tanggapan organisme terhadap ransang. Ransang dapat dating dari luar (eksternal) atau dari dalam (internal) tubuhnya sendiri. Sebenarnya tumbuhan itu dapat melakukan gerakan-gerakan walaupun kebanyakan tidak terlalu terlihat mencolok. Contoh tumbuhan yang paling terlihat gerakannya yaitu seperti putri malu yang suka tumbuh liar di pinggir jalan. Ketika daunnya kita sentuh maka daun yang ada akan spontan menutup. Itulah yang namanya iritabilitas (irritability), di mana tumbuhan dapat menerima dan menanggapi rangsangan. Setiap makhluk hidup bisa bergerak walaupun sangat lamban karena salah satu ciri makhluk hidup adalah bergerak. Pergerakan tumbuhan dapat disebabkan oleh adanya rangsangan / stimulus yang berasal dari luar. Arah gerakan bisa mendekati atau juga bisa menjauhi rangsangan. Macam / Jenis Gerak Pada Tumbuhan : Menurut penyebabnya gerak pada tumbuhan dibedakan menjadi :

1. Gerak higroskopis Adalah gerak yang disebabkan oleh pengaruh pertumbuhan kadar air. Contoh : - pecahnya buah polongan (petai cina, jarak) - membukanya anulus pada sporangium (kotak spora) pada tumbuhan paku-pakuan - membuka dan menutupnya sporangium pada tumbuhan lumut oleh peristom 2. Gerak ethionom Adalah gerak tumbuhan yang disebabkan oleh rangsangan dari luar. Berdasarkan sifatnya gerak ethionom dibedakan menjadi : a. Tropi atau tropisme Adalah gerak bagian tubuh tumbuhan ke arah rangsang (tropi positif) dan menjauhi rangsang (tropi negatif), meliputi : - Fototropi (heliotropi) : adalah gerak batang ke arah cahaya. - Geotropi : adalah gerak tumbuh akar ke pusat bumi. - Hidrotropi : adalah gerak tubuh tumbuhan ke arah air. - Tigmotropi (haptotropi) : adalah gerak membelok bagian tanaman sebagai akibat persinggungan . contoh : membelitnya ujung batang dan sulur Cucurbitaceae. - Kemotropi : adalah gerak karena rangsang kimia contoh : akar menuju zat makanan atau menjauhi zat racun b. Taksis (gerak pindah tempat) Adalah gerak pindah tempat oleh tumbuhan (besel satu) atau bagian tumbuhan menuju atau menjauhi arah datangnya rangsang, meliputi : - Fototaksis : rangsangannya cahaya contoh : Kloroplas bergerak ke sisi sel yang mendapatkan cahaya matahari. Euglena viridis selalu bergerak menuju tempat yang terkena cahaya. Spora jamur Pilobolus akan bergerak menuju tempat yang terkena cahaya. - Kemotaksis : rangsangannya adalah zat kimia contoh : Bacteri aerob selalu berkumpul pada tempat yang banyak
