How is fungus and protists beneficial to us?
Fungus and protists help us in many ways. Fungus and protists are used in food to make it tasty. Example of a fungus used in food is yeast (makes your bread rise). Medicine for example Penicillin comes from a mold of Penicillium. They affect our ecosystems and are used for industrial purposes.
An amoeba consists of a single cell and has a nucleus what is an amoeba called?
An amoeba is a type of single-celled organism belonging to the phylum Amoebozoa. It is classified as a protist, specifically a unicellular eukaryote.
What do you call a protist that acts like an animal?
A protist that acts like an animal is called a protozoan. Protozoa are single-celled eukaryotic organisms that exhibit animal-like behaviors such as hunting, moving, and consuming prey.
What food products contain brown algae?
Brown algae, specifically species like kelp, are commonly used in Asian cuisines. They can be found in various food products such as sushi, seaweed salad, miso soup, and some types of noodles. Brown algae are also used to make various condiments like nori seasoning and dashi broth.
When does the planktonic algae population peak?
Planktonic algae populations typically peak in warmer months when sunlight and nutrients are abundant, promoting their growth. In temperate regions, this peak often occurs in the spring and summer.
Name the processes that are involved in the transport of materials in protists?
In protists, the processes involved in the transport of materials include diffusion, active transport, phagocytosis, and pinocytosis. Diffusion allows small molecules to passively move across the cell membrane, while active transport uses energy to move materials against a concentration gradient. Phagocytosis involves the engulfment of solid particles by the cell, while pinocytosis facilitates the uptake of fluids and dissolved molecules.
What is the normal speed of a Rattlesnake?
Rattlesnakes typically move at speeds of about 2-3 miles per hour. They are relatively slow-moving snakes, relying more on camouflage and ambush tactics to catch prey rather than pursuing it over long distances.
What products are made from a plantlike protists?
Plantlike protists, such as algae, are used to make various products such as food supplements like spirulina and chlorella, cosmetics, and biofuels. Algal blooms can also be used to help in wastewater treatment.
What are diatomic molecules list all of them?
Some examples of diatomic molecules include hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2). These molecules consist of two atoms of the same element bonded together.
What is the kingdom phylum class order family genus species of a Protists?
Protists belong to the kingdom Protista. As Protists is a diverse group, it can further be classified into various phyla, classes, orders, families, genera, and species depending on the specific organism in question.
Is plasmodium vivax a sporozoan?
Plasmodium vivax, the protist that causes Malaria, is a sprozoan, which is a type of protist that doesn't move on its own, is parasitic by penetrating then living inside of its host, and it can have more than one host at a time.
What are 2 ways protists can be classified?
1. By the way they get their nutrition
a. photoautotroph (do photosynthesis, have chloroplasts to produce their
own energy like plants)
b. heterotroph (either absorb nutrients like fungi or ingest nutrients like
animals)
c. mixotrophs (combine both ways to obtain nutrition)
2. The way they move
a. with cilia (ciliates)
b. with a flagella (flagellates)
c. by expanding and contracting their cytoplasm (look at a video of ameoba
moving)
What evidence exists to support the idea that poriferans evolved from protists?
One piece of evidence supporting the idea that poriferans evolved from protists is the similarity in genetic sequences between certain protists and sponges. Additionally, some protists share characteristics with poriferans, such as the presence of collar cells, which suggests a possible evolutionary relationship between the two groups. Studies of early fossil records also provide some evidence of a transitional form between protists and sponges.
What causes the dinoflagellates to glow?
Dinoflagellates glow through a phenomenon known as bioluminescence. This is triggered by movement or disturbances in the water, which activate a chemical reaction involving a light-emitting molecule called luciferin and an enzyme called luciferase within the dinoflagellates' cells. This reaction produces a blue-green light visible as a shimmering glow in the water.
How does osmosis and diffusion help an amoeba survive?
Osmosis and diffusion help an amoeba survive by allowing it to take in essential nutrients and water from its environment and release waste products. Through these processes, the amoeba is able to maintain the necessary balance of molecules and ions inside its cell to support its biological functions.
What is regulation in unicellular protists?
Regulation in unicellular protists refers to the ability of these organisms to maintain internal stability despite changes in their external environment. This may involve processes like osmoregulation to control water balance, thermoregulation to maintain proper temperature, or pH regulation to manage acidity levels. Regulation mechanisms enable unicellular protists to survive and function effectively in different environmental conditions.
What are the zoological importance of amoeba?
Amoebas play a crucial role in the ecosystem as they are important decomposers, breaking down organic matter and recycling nutrients. They are also a food source for many organisms, contributing to the food chain. Additionally, studying amoebas helps researchers understand cell biology and evolution.
Can a protist be seen with the naked eye?
yes.. i think there are a few because a saw a very quick one in science class today when a put a drop of water on my slide for the microscope.
How does a paramecium obtain nutrition?
A paramecium obtains nutrition through a process called phagocytosis, where it engulfs food particles along with water into its oral groove. The food particles are then enclosed in a food vacuole, where enzymes break them down for digestion. Waste materials are expelled through a structure called the anal pore.
Algae can be green, red, brown, or yellow depending on their pigments. Green algae, for example, contain chlorophyll for photosynthesis, while red algae contain phycoerythrin and phycocyanin pigments in addition to chlorophyll. Brown algae possess fucoxanthin pigments.
Are there ribosomes in protista?
Yes, protists contain ribosomes which are responsible for protein synthesis within the cell. Ribosomes are found in the cytoplasm of protist cells and play a crucial role in producing proteins necessary for cell function.
Sarcodines, such as amoebas, obtain food through phagocytosis. They use their pseudopods to surround and engulf food particles or other organisms. Once surrounded, the food is taken into a food vacuole for digestion.
What is a difference between desmids and diatoms?
Diatoms are stramenophila algae, their cell wall is composed of silica and their chloroplasts are yellowish-brown. Desmids are green algae, their cell wall is composed of cellulose and pectins (like plants), and their chloroplasts are green.
