What organisms are in the Ochrophyta phylum?
A wide array of freshwater planktonic and benthic algae, including numerous cyanobacteria and ochrophytes (Ochrophyta: some diatoms, chrysophytes, synurophytes, and tribophytes), but also cryptophytes (Cryptomonas rostratiformis Skuja), dinoflagellates (Peridinium sp., Gymnodinium sp.), and chlorophytes (e.g..

Do diatoms belong to chlorophyta?
Diatoms: unicellular organisms of the kingdom protista, characterized by a silica shell of often intricate and beautiful sculpturing. Most diatoms exist singly, although some join to form colonies. Chlorophyta: division of the kingdom of protista consisting of the photosyntetic organism commonly known as green algae.
Where is Ochrophyta found?
The Ochrophyta are found in virtually all biotopes: waters marine, freshwater or wetland environments. Some are associated with Eumycota to form lichens. Many species have retained the ability to phagocyte prey and nourish by mixotrophy; others can live by osmotrophy.
Is brown algae a protist?
The Classification of Algae Table below lists some of the larger groups of algae. Green algae include many single-celled, motile organisms. Others are non-motile, and some (called seaweeds) are truly multicellular….Classification of Plant-like Protists.
| Phylum or Division | Heterokontophyta |
|---|---|
| Class | Phaeophyceae |
| Common Name | Brown algae |
| Body Form | Multicellular |
Is a dinoflagellate a phytoplankton?
The two main classes of phytoplankton are dinoflagellates and diatoms. Dinoflagellates use a whip-like tail, or flagella, to move through the water and their bodies are covered with complex shells. When too many nutrients are available, phytoplankton may grow out of control and form harmful algal blooms (HABs).
What is Chlorophyta in biology?
Originally, Chlorophyta referred to a division within the Plantae kingdom comprising all green algae species. Green algae enclose chlorophyll that converts sunlight to starch to be stored as a food reserve within their cells. Most species have rigid cell walls made of cellulose, saccharides, and proteins.
What is the classification of Ochrophyta?
Ochrophyta seaweed are divided into 20 classes (Guiry and Guiry, 2014). In the Phaeophyceae class, over 1800 species of brown algae are found (Guiry and Guiry, 2014). The Dictyotales, Ectocarpales, Fucales, and Laminariales are orders that include the most species.
Does Chlorophyta reproduce sexually or asexually?
Most Phylum Chlorophyta reproduces both sexually and asexually, like many other non-vascular plants. In asexual reproduction, there are spores and zoospores which develop directly into new plants. However, in sexual reproduction, pairs of sex cells, or gametes, fuse to produce a new plant.
Are stramenopilans heterotrophic or photoautotrophic?
Some stramenopilans are heterotrophic (e.g., the oomycetes), whereas others are photoautotrophic (e.g., the phaeophytes). Figure 3.
