Botany practical

Acanthophora spicifera - Rhodophyta

Thallus: Brittle, spiny

Branches: Cylindical, irregularly radical

Branchlets:Uniformly abundant short with spur like spines

Hypnea musciformis - Rhodophyta

Thallus: bushy, tangled, wiry, thin

Branching: Irregular, sparse

Branchlets: Numerous slightly up curled ends

Parenchymatous cell packing

Gracilaria Blodgettii - Rhodophyta

Thallus: Tough cartilaginous

Branching: cylindrical, alternate and disproportional

Branchlets: cylindrical arched inward constricted at the base ends are round and round and tapered

cells are parenchymatous and irregular

long slender taper, favors branching to one side, pinching at base when branching

Hypnea cervicornis - Rhodophyta

wiry pointed straight branchlets thin irregular branching fork like ends

Gracilaria tikvahiae - Rhodophyta

Thallus: highly variable, delicate sparse clumps branched tightly

branching cylindrical arched outward apex tapered and pointed

irregular parenchymatous cells

Solieria filiformis - Rhodophyta

a smooth, mucousy and cartilaginous alga with cylindrical branches that are very flexible and branch dichotomously

Has diffused filamentous cell packing with thick cells walls

Dictyota cervicornis - Phaeophyta

Flat, branching in to two groups

cells like corn on the cob, rectangular

thallus: bushing and branching dichotomously asymmetrical

branches: wide twisted or spirla apex is pointed

Ulva fasciata - Chlorophyta

Thin sheetlike

Blades two cells thick

no stalk

cells are irregularly arranged

Ulva lactuca - Chlorophyta

thin sheet like

cells are square and regularly arranged

Enteromorpha intestinalis - Chlorophyta

thallus: flacid gergarious cylindrical or flattened tubes in clusters or tufts

Blades: hollow, tubular, tapering towards base

cells: rounded rectangular not in linear rows unordered through out

Caulerpa prolifer - Chlorophyta

Frond: Thin delicate to thick undivided oval to elongated dark green

stalk short and slender

Cladophora liniformis - Chlorophyta

green seaweed that forms unattached masses of simple or sparsely and irregularly branched light to dark (bluish) green filaments up to 9 cm long. The branches are separated at the base by an oblique dividing wall. It is common in sheltered brackish environments but its seasonality is poorly known.
