Algae 1
I.    Standar Kompetensi    :  2. Memahami prinsip-prinsip pengelompokan makhluk hidup.
II.    Kompetensi Dasar     : 2.3 Menyajikan ciri-ciri umum filum dalam Kingdom Protista, dan
                          perannya bagi kehidupan.
III.    Indikator             : Mengidentifikasi ciri-ciri Algae
IV.    Tujuan            :
•    Mendeskripsikan ciri-ciri Algae.
•    Memberi contoh peranan Protista bagi kehidupan.
        Pendahuluan
Alga adalah penghuni perairan ( laut dan air tawar ) serta tempat tempat yang cukup basah. Karena memiliki klorofil, alga itu autotrof. Banyak alga bersel tunggal merupakan fitoplankton. Di samping itu terdapat alga yang multiseluler. Struktur  tubuhnya berbeda dengan tumbuhan yang lain, ia tidak berakar, berbatang dan berdaun sejati. Perbedaan lainnya ialah disamping berklorofil seringkali memiliki pigmen lainnya. Melalui kegiatan ini kita akan memahami alga mikroskopis dan alga makroskopis.
V.    Alat/Bahan/Sumber :
       Alat dan bahan :
1.    Botol untuk mengumpulkan akar
2.    Kaca objek
3.    Mikroskop
4.    Kaca penutup
5.    Pipet
6.    Awetan alga
7.    Kaca pembesar
VI.    Rincian Kegiatan :
1.    Ambillah air yang berwarna hijau dari kubangan, sawah, kolam atau tempat lain dan kikislah batu batu tembok yang berwarna hijau dan masukkan ke dalam botol
2.    Berilah label pada tiap tiap botol
3.    Amatilah macam macam air tersebut dibawah mikroskop
4.    Bila sulit menemukan alga bersel satu lewatkan air itu di atas kertas saring, pindahkan benda benda yang tertinggal diatas kerta saring itu keatas kaca objek, periksalah dengan mikroskop.
5.    Amati alga yang didapatkan mula mula dengan lup, kemudian dibawah mikroskop
6.    Gambarlah bentuk  macam macam bentuk alga yang kamu temukan kemudian bandingkan dengan gambar gambar yang terdapat dalam buku paket Biologi kelas X.

NO.    Gambar /             Nama Alga    Warna    Habitat    Keterangan

       







VII.    Pertanyaan :
1.    Berdasarkan hasil pengamatan dari kegiatan nomor 6 ? Bandingkan dengan hasil pengamatan alga pada kegiatan nomor 7 !
2.    Jenis air mana yang banyak alganya?
3.    Apa yang menyebabkan alga berwarna? Ada berapa macam warna alga?
4.    Apa peranan alga dalam ekosistem kolam ?
5.    Apa yang terjadi bila tidak ada alga di dalam laut ?
6.    Tuliskan jenis-jenis alga yang bermanfaat bagi kehidupan manusia da lingkungan sekitar !
