What are the characteristics of Ulothrix?
Ulothrix, genus of filamentous green algae (family Ulotrichaceae) found in marine and fresh waters. Each cell contains a distinct nucleus, a central vacuole, and a large thin chloroplast with at least one pyrenoid. The specialized cell for attachment is called the holdfast, and the filaments are typically unbranched.

What is the difference between Ulothrix and spirogyra?
Spirogyra, Ulothrix and Volvox are examples of green algae. They contain chlorophyll and are mostly found in fresh water. … But the difference between these three is that Spirogyra and Ulothrix, are filamentous in shape whereas Volvox forms spherical colonies of up to 50,000 cells.
What kind of organism is Ulothrix?
On the other hand, Ulothrix is a genus of filamentous green algae, generally found in fresh water and marine and abundantly available in some lakes and rivers of Turkey.
Does Ulothrix have chlorophyll?
Complete answer: Ulothrix is a green alga belonging to the phylum of Chlorophyta. Ulothrix belongs to the family Ulotrichaceae. The green colour of the algae is due to the presence of a green colour pigment called chlorophyll. … The body structure of the Ulothrix is unbranched and consists of uniseriate filaments.
Is Ulothrix a Thallophyta?
Thallophyta- Thallophyta are divided into three classes: (i) Chlorophyceae – They are green algae e.g. Ulothrix, cladophora, volvox, spirogyra etc. (iii) Rhodophyceae – commonly called red algae, e.g. Gracilaria, Gelidium and Porphyra etc. (iv) Algae is used as food.
What is the life cycle of Ulothrix?
Hence, the Life cycle in Chlamydomonas, Ulothrix, Spirogyra is haplontic. Note: Starting with a diploid zygote or spore and finishing with a fully mature alga plant, all algae go through a haploid life cycle of growth. Algae are divided into three classes: Chlorophyceae, Phaeophyceae, and Rhodophyceae.
Is Eudorina a colonial?
Eudorina colonies typically consist of 16, 32 or 64 cells, each of which is similar to Chlamydomonas reinhardtii. … Colonies are spherical and motile, with motility derived from the flagellated individual cells. Eudorina is facultatively sexual, meaning colonies can reproduce either sexually or asexually.

Where are Pyrenoids located?
Pyrenoids are located in the chloroplast.
What is discoid chloroplast?
In higher plants, the chloroplast is disc shaped or discoid. The chloroplast contains stroma which is the protein rich, aqueous, alkaline fluid within the inner membrane and outside the thylakoid space. Hence, the correct option is A. Discoid.
Is Ulothrix a colony?
Ulothrix is categorized as a genus of non-branching filamentous green algae, normally found in fresh and marine water. They attach to the surfaces by a modified holdfast cell and its reproduction is normally vegetative. … It makes spherical colonies having up to 50,000 cells.

What is the function of Pyrenoid in Chlamydomonas?
The pyrenoid is a microcompartment within the chloroplasts of algae and hornworts. Its known function is to promote photosynthetic CO2 fixation by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco).
Is Chlamydomonas unicellular or multicellular?
Chlamydomonas reinhardtii, a unicellular, photosynthetic green alga in the Chlamydomonadaceae, has never had a multicellular ancestor yet is closely related to the volvocine algae, which express multicellularity in colonies of up to 50,000 cells [4].
Is Ulothrix a producer?
Ulothrix is a type of green algae. Algae is a producer and so ulothrix is also a producer.
Is Ulothrix brown algae?
Ulothrix – They are green, filamentous algae, mostly found in freshwater with low salinity areas like; ponds, lakes etc. … Ectocarpus – They belong to the group of brown algae and mostly found in the colder wetlands. They are commonly found in marine water bodies.
Is Ulothrix a protist?
Algae, Cyanobacteria, and Protists
Ulothrix zonata and Hydrurus foetidus are the common attached filamentous algae.
Is Ulothrix flagellated or non flagellated?
Ulothrix is a fresh water, filamentous green algae, found in rather cold flowing water. Sexual reproduction in Ulothrix is isogamous type i.e., it takes place between two morphological similar motile, flagellated male and female gametes which come from different filaments.
Is Ulothrix flagellated algae?
They are green algae that have two flagella, found in stagnant water, in freshwater, seawater, and on moist soil and even in the snow. a) Ulothrix is filamentous green algae with a cosmopolitan distribution in fresh and marine water. … They don’t have any flagella.
What are Pyrenoids made of?
The pyrenoid, a dense structure inside or beside chloroplasts of certain algae, consists largely of ribulose biphosphate carboxylase, one of the enzymes necessary in photosynthesis for carbon fixation and thus sugar formation. Starch, a storage form of glucose, is often found around pyrenoids.
