Plant like Protist (algae)
and Advantages of Protista
Characteristic of Alga ● Sizes
- Microscopic (25μm), Ex: Navicula.
- Macroscopic (50m), Ex: Macrocystis.
Navicula Macrocystis
● Shape of body
a. Uniselluler
- Solitter (Ex: Chlorella don’t have flagel).
- Coloni (Ex: Gonium, Volvox, Hydrodictyon).
Chorella Volvox
b. Multiseluler
Ex: Spirogyra, Oedogonium, dan Ulva.
Spirogyra Ulva
● Body structure and function
- Has membrane nucleus (eucarotic)
- Cell have chloroplas (in cell contain pigment to
absorp light for photosyntesis
- Main pigment: clorophyll
add pigment: karoten (xantofil and fikobilin) and
fikobilin (fikosianin/fikoritrin)
- Has pirenoid, for reserve food place
● Habitat and the way life
- Fotoautotrof
useful as produsen for heterotrof organism, in
supplying food and oxigen
- Free life in damp habitat/water, ex: swamp, river,
soil, stone, or tree
● Reproductiona. Axesual (vegetatif)
- Division cell (only in uniseluler algae)- Fragmentation (in multiseluler algae
filamen/thallus shape)- Zoospora (uni and multiseluler)
b. Seksual (generatif)- Isogami- Oogami
Klasifikasi Alga
● Euglenoid (Euglenophyta)- Uniseluler, cell pakaged by pelikel (kind of protein)- Procariot- Has stigma contain fotoreseptor- Has two flagellum- Habitat: water- Food reseve: paramilon
- Reproduksi: axesual (biner division)
- Ex: Euglena.
Euglena
● Gold Algae (Chrysophyta)
- Uniseluler soliter and multiseluler
- Compose cell wall: hemiselulosa, silika, and
pektin
- Pigmen: karoten (santofil)
add pigmen : fukosantin, chlorophyl a and c.
- Reseve food: lipid and charbohidrate
- Habitat: water and sea
- Reproduksi: a. axesual (biner division, spora shape)
b. sexual ( joint two kids of gammet)
- Ex: Navicula, Synura, and Mischococcus.
Synura
● Ganggang api (Dinoflagellata / phyrrophyta)
- Uniseluler fotosintetik
- Dinding sel mengandung selulosa
- Pigmen: klorofil a dan c, santofil, dinosantin, dan fikobilin.
- Memiliki 2 flagellum
- Merupakan produsen utama fitoplankton laut
- Habitat: air laut
- Reproduction: asexual (biner division)
- Ex: Gonyaulax, Noctiluca scintillans.
Gonyaulax Noctiluca scintillans
● Green Algae (Chlorophyta)
- Uniseluler and multiseluler
- Cell wall compose from cellulose
- Pigmen: klorofil (klorofil a and b)
add pigment: karoten
- Reseve of food: amilum
- Habitat: water
- Reproduction: a. asexual (spora shape, fragmentation, and self division)
b. sexual (isogami, anisogami,
oogami)
- Ex: Volvox, Gonium, and Chlamydomonas.
Chlamydomonas
● Brown Algae (Phaeophyta)
- Multiseluler, like thread or thallus
- Pigment: karoten (fukosantin)
add pigment: chlorophyl a dan b, xantofil
- Cell wall contain pektin and algin
- Food of reseve: laminarin
- Habitat: sea
- Reproduksi: a. axesual (Fragmentation and zoospora)
b. sexual ( isogami, unisogami, and
oogami)
Ex: Sargassum, Macrocystis, Turbinaria.
Sargassum Turbinaria
● Red Algae (Rhodophyta)
- Pigmen: fikoeritrin
add pigment: chlorophyll a and d, karoten,
fikosianin
- Multiseluler
- Cell wall contain pektin and cellulose
- Reseve of food: florid flour
- Habitat: in deep sea
- Reproduksi: a. axesual (spora)
b. sexsual (oogami)
- Ex: Eucheuma spinosum.
