Jaringan Pada Tumbuhan
Ayu Dwi Apriliana, S.Pd.
A. Jaringan Meristem
Yaitu jaringan yang bersifat non meristematik atau tidak aktif membelah, yang berasal dari jaringan meristem primer dan sekunder.
Berdasarkan fungsinya jaringan dewasa dibedakan menjadi 5 yaitu jaringan pelindung (Epidermis), jaringan dasar(Parenkim), jaringan penyokong, jaringan pengankut (Vaskuler) dan jaringan Sekretori.
Jaringan pelindung (Epidermis) jaringan yang tersusun dari lapisan sel yang menutupi permukaan organ tumbuhan , c/; Akar, Batang,Daun,buah dan Biji. Berfungsi melindungi bagian dalam tumbuhan dari segala pengaruh luar.
Sel epidermis dapat bermodifikasi menjadi alat-alat tumbuhan lain disebut derivat epidermis, yaitu stomata (Mulut daun), Trikoma (Rambut-rambut), Emergensia, dan Spina (Duri).
Jaringan Dasar (Parenkim) jaringan yang terbentuk dari sel-sel hidup yang terdapat disetiap bagian organ. Berfungsi sebagai penyimpanan makanan (buah & biji), sebagai tempat ftosintesis (daun), dan untukmenyimpan makanan dan air ( Akar )
Berdasarkan fungsinya terbagimenjadi 6 yaitu ; �Parenkim Asimilasi (Pembuata zat-zat makanan dengan cara fotosintesis) Parenkim Penimbun Parenkim air, Parenkim Udara, parenkim pengankut danparenkim penutup luka.
Jaringan Permanen (Jaringan Dewasa)
Jaringan Penyokong (Penguat). Jaringan yang menunjang bentuk tubuh tumbuhan. Berfungsi menegakkan batang dan menguatkan daun.�Berdasarkan bentuk dan sifatnya dibagi menjadi 2 yaitu jaringan Kolenkim danjaringan Sklerenkim.
Jaringan pengangkut (Vaskuler) �jaringan yang berfungsi mengangkut air dan garam-garam mineral, serta zat makanan hasil fotosintesis. Jaringan pengankut adalah xilem dan floem .
Jaringan Sekretori, �jaringan yang berfungsi sebagai tempat pengeluaran senyawa-senyawa dari dalam tumbuhan seperti air, mineral, lendir, getah, minyak dan lemak.
Berdasarkan bentuknya jaringan dasar dibagi menjadi 4 yaitu ; Parenkim Palisade, Parenkim bunga karang,Parenkim bintang, Parenkim Lipatan,

Organ Pada Tumbuhan
Perbedaan Anatomi Tumbuhan Monokotil dengan Dikotil
No | Organ | Monokotil | Dikotil |
1. | Akar | Memiliki parenkim,tidak memiliki kambium, xilem dan floem terletak berselang seling. | Tidak memiliki parenkim, memiliki kambium , xilem terletak dipusat akar dan floem terletak diluatr xilem |
2. | Batang | Batas antara korteks dan stele kurang jelas, antara xilem dan floem tidak ada kambium. | Batas antara korteks dan stele jelas, antara floem dan xilem terdapat kambium. |
3. | Daun | Tidak memiliki jaringan parenkim palisade, tetapi tersusun dari sel-sel parenkim yang struktur danukurannya seragam. | Memiliki jarigan palisade pada sisi atas dari bagian atas daun. |
Sifat Totipotensi dan Kultur Jaringan
.
Jenis kultur jaringan
Meristem culture ; yaitu teknik kultur jaringan menggunakan eksplan dari jaringan muda atau meristem
Pollen/Anther culture; menggunakan eksplan dari serbuk sari atau benang sari.
Protoplast culture; menggunakan eksplan dari protoplasma (Sel hidup yang telah dihilangkan seldindingnya)
Chloroplast culture; menggunakan eksplan kloroplas untuk tujuan perbaikan sifat tanaman dengan membuat varietes baru.
Somatic cross; Silangan Protoplasma, yang menyilangkan dua macam protoplasma menjadi satu,kemudian di budidayakan menjadi tanaman baru.
Sterilisasi, Segala kegiatan kultur jaringan harus dilakukan dengan steril.
Teknik Kultur Jaringan
Pembuatan Media ,media yang diguanakan adalah garammineral, vitamin, hormon, agar-agar dan gula.
Insiasi, Pengambilan eksplan dari bagian tanaman yang akan dikultur yaitu tunas.
Multiplikasi, Kegiatan memperbanyak calon tanaman dengan menanam eksplan pada mdia pot, tanah atau rak.
Pengakaran, Fase saat ekspan akan menunjukan adanya pertumbuhan akar.
