Protists

Some protists that use spores to reproduce include slime molds, water molds, and various types of algae. Spores are typically formed as a means of survival under unfavorable conditions, allowing these protists to spread and germinate when conditions become more suitable.

All protists have a nucleus and are eukaryotic. They can be unicellular or multicellular, and they exhibit diverse modes of nutrition such as autotrophic, heterotrophic, or mixotrophic. Additionally, protists possess various organelles like mitochondria, plastids, and flagella.

Categories of protists based on how they obtain food do not necessarily reflect their evolutionary relationships. For example, some protists can switch between different methods of obtaining food depending on their environment. Additionally, the same method of obtaining food can be found in distantly related protist groups.

Blepharisma is a type of ciliated protozoan that is harmless to humans. It is commonly found in aquatic environments like ponds and streams, where it feeds on bacteria and other microorganisms. Blepharisma does not pose any known health risks to people.

Fungi can be larger than protists because fungi are multicellular organisms, while some protists are single-celled organisms. Fungi can form complex structures like mushrooms and molds, which can be larger than individual protist cells.

Spyrogyra is classified as a genus of green algae in the family Zygnemataceae. It is a filamentous algae that is commonly found in freshwater habitats.

Euglenophytes have unique characteristics such as a flexible pellicle for shape-changing, chloroplasts with three membranes, and the ability to be both autotrophic and heterotrophic. They also have a single emergent flagellum for movement and a distinct feeding groove for nutrient uptake, setting them apart from other protists.

A euglena has a flagellum for movement, which amoeba and paramecium do not have.

Phagocytosis is the process by which a bloblike amoeba surrounds a particle of food, creating a food vacuole that then merges with lysosomes for digestion.

Yes, oceans have algae. Algae are simple plants that can be found in various forms and colors in ocean waters. They are important for marine ecosystems as they form the base of the food chain and produce a significant amount of the Earth's oxygen through photosynthesis.

Phytophthora was responsible for the Irish Potato Famine

Spirulina and chlorella are two types of algae that are considered beneficial for health. They are packed with nutrients, vitamins, and antioxidants, and have been shown to support immune function, detoxification, and overall well-being. It is important to source these algae from reputable brands to ensure their purity and quality.

Fungi are the group of organisms that are all absorptive in their nutrition. They break down organic matter externally and absorb the nutrients. This is in contrast to plants that perform photosynthesis and animals that ingest food.

Halogens are group VII in the periodic table, which is F2, Cl2, Br2, I2. they exist as diatomic molecules. why? let's take F as the example. F have seven electrons in its outer shell (2 on top, 2 on the right side, 2 on the left side, and 1 on the bottom). the electron that is located at the bottom of the shell is unpaired. so, two F atoms shared their unpaired electron with each other to form a single covalent bond. this goes for Cl, Br, and I too.

No, a paramecium is not a phytoplankton. Paramecium is a single-celled organism classified as a protist, while phytoplankton are a diverse group of microscopic photosynthetic organisms that include algae and cyanobacteria. Phytoplankton play a crucial role in marine ecosystems by serving as the base of the food chain through photosynthesis.

Plantlike protists, such as algae, play a crucial role in aquatic ecosystems by serving as the base of the food chain. They are primary producers that convert sunlight into energy through photosynthesis, providing food and oxygen for a wide variety of aquatic organisms. Their diverse forms and functions contribute significantly to the overall biodiversity of aquatic ecosystems.

Brown algae are primarily autotrophic, meaning they can perform photosynthesis to produce their own food using sunlight, water, and carbon dioxide. However, they can also be partially heterotrophic, meaning they can absorb nutrients from their environment to supplement their energy needs.

Some mollusks, like certain species of snails and clams, may feed on algae. Others, like some species of bivalves, may filter feed on plankton by drawing water into their bodies and trapping plankton to feed on. It ultimately depends on the specific species of mollusk.

Yes, Plasmodium does affect mosquitoes. It infects and multiplies within the mosquito's gut before moving to its salivary glands, where it can be transmitted to humans when the mosquito bites.

Advantages: Protists play important roles in ecosystems as primary producers, consumers, and decomposers. They are also used in research to study evolution and genetics.

Disadvantages: Some protists are pathogenic and can cause diseases in humans, animals, and plants. They can also disrupt ecosystems when they become invasive species.

Yes, paramecium is a unicellular organism. It is a type of protozoa that falls under the group of single-celled eukaryotes and is commonly found in freshwater environments.

Algae fall under the Kingdom Protista. They are a diverse group of photosynthetic organisms that can be found in various habitats, including freshwater and marine environments.

Most are harmless. A few can become parasites.

amoeba's the single cell organism's are not harmful to humans. Matter of fact you most likely have Millions of amoeba and other single cell organisms living around and inside you at all times. And by the way you spelled amoeba wrong.

No, paramecium are not autotrophs. They are heterotrophic organisms, meaning they obtain their nutrients by ingesting organic matter such as bacteria and algae. Autotrophs, on the other hand, are organisms that can produce their own food through processes like photosynthesis.
