Blooms of certain dinoflagellates are associated with all what except?
Blooms of certain dinoflagellates are associated with all of the following: red tides, harmful algal blooms (HABs), production of toxins, and increased water turbidity.
What animal-like characteristics do euglenoids have?
Unlike other algae, euglenoids have one animal-like characteristic that allows them to be heterotrophs under certain conditions. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ than wtf is it??? that's sort of the damn question -_-
Protist are what kind of organism?
Protists are eukaryotic organisms that are neither plants, animals, fungi, or bacterias. The 5 Super groups of Protists Include: Excavata, Chromalveolates, Rhizaria, Archaeplastida, and Unikonts. Excavata: Diplomonads, Parabalalids, Eugleozoans (Kinetoplastids and Euglenids) Chromalveolates: 1. Alveolates (Dinoflagellates, Apicomplexans, Ciliates) 2. Stramenophiles ( Golden Algae, Brown Algae, Diatoms, and Oomycetes) Rhizaria: Chlorarachniophytes, Forams, Radiolarians Archaeplastida: Red Algae, Green Algae (Cholorophytes, Charophyceans), Land Plants* Unikonts: Amoebazoans (Slime mold, Gymnamoebas, Entamoebas), and Opisthokonts ( Nucleariids, Fungi*, Choanoflagellates, Animals*) * Although these Eukaryotic groups are also kingdoms, they share similarities to certain groups of Protists. The protist kingdom is a very diverse and vast grouping that is sometimes difficult to characterize.
What are the visible structures that is present in protist cell which is not present in animal and plant cell?
Protists are a very diverse group and may contain a combination of these structures as well as those shared by plants, animals, and fungi.-Contractile vacuoles, like those found in protozoa, are structures that gather water and then squeeze it out of the cell to maintain the proper osmotic balance. Found in single-celled freshwater protists.-Cysts are protective coatings made by some protozoa when conditions are unfavorable (usually due to a lack of food or water).-If the protist has a protective/supportive structure (pellicle) it will often have specialized sections for food intake: cytostomes are openings in the covering that act as a mouth to allow food to enter and anal pores are sites for excretion of waste.-An Oral groove is an indentation in the cell structure that directs the floating food particles into the gullet. At the end of the gullet is the cytostome where food is packaged into food vacuoles.-Many protists have a macronucleus and micronucleus. The macronucleus is the larger nuclei and controls all the cell functions except reproduction (vegetative function). The micronucleus is the smaller nuclei and controls the cell's reproduction (generative function).-Glycosomes are membrane-enclosed organelles found in a few pathogenic species of protozoa. These organelles contain glycolytic enzymes (proteins that breakdown glucose). It is most recognizable in the human pathogenic trypanosomes (like those responsible for sleeping sickness).-An Eyespot apparatus (also called Stigma) is an organelle that can detect light, its intensity and its direction. It can be found in some motile species of green anlgae and other photosynthetic single-celled organisms (like euglenids). Using this organ the organism can respond by postitive phototaxis (swimming towards the light) or negative phototaxis (swimming away from the light).
What is an eyespot and what is it function?
An eyespot, often called a stigma (derived from Greek for "spot"), is a heavily-pigmented organelle located near the cell membrane that seems to function in light reception in certain single-celled organisms. (It may also refer to a region of light-sensitive cells in the epidermis of certain invertebrates like worms and starfish that performs the same function.) An example of single-celled organisms that have an eyespot are euglenids. These organisms have bright red eyespots, which structurally are pigment-filled shields near the flagellum. Because they are next to the locomotive organelle, stimulation of the eyespot with light also stimulates the flagellum, enabling the euglenid to move in response to light so as to find better light conditions for photosynthesis. Chlamydomonas are another green algae that have an eyespot, this one composed primarily of carotenoids and calcium ions. Considering that photosynthesis and eyespot functions are based on many of the same chemical principles, it's not surprising to find these two things together in many single-celled organisms. Whether eyespots are related to the development of higher-level eyes is currently an open question. A number of evolutionary scenarios suppose that once one gets light-sensitive cells, the further development of complex eyes is a fairly smooth transition.
Are euglenid chemoheterotroph?
Euglenids are primarily known as photosynthetic organisms due to their chloroplasts, allowing them to perform photosynthesis. However, they are also considered chemoheterotrophs because they can obtain nutrients by absorbing organic compounds from their environment, particularly when light is scarce. This dual ability enables them to thrive in various habitats, adapting to different nutritional conditions.

What are the plant-like protists?
A plant like protist is a Eukaryotic organism that lives in a wet or moist environment. It has a cell wall and contains a green pigment, chlorophyll. Chloropyll helps the plant like protist produce its own food through photosynthesis. Most plant like protists are autotrophs, but some are partly heterotrophs. They are known as algae. Examples of plant like protists are dinoflagellates, euglenoids, diatoms, red algae, brown algae, and green algae.
