Protists

The kingdom Protista includes a diverse range of organisms, primarily categorized into three main groups: protozoa (animal-like protists), algae (plant-like protists), and slime molds (fungus-like protists). Protozoa include organisms such as amoebas and paramecia, while algae encompass various types like green algae, brown algae, and diatoms. Slime molds and water molds represent the fungus-like protists. This kingdom is characterized by its vast diversity, with members ranging from unicellular to multicellular forms.

Pseudopods are temporary, foot-like extensions of a protist's cell membrane that facilitate movement and feeding. They allow protists to crawl along surfaces by extending and retracting, enabling them to navigate their environments. Additionally, pseudopods can engulf food particles through a process called phagocytosis, allowing protists to capture and consume nutrients from their surroundings. This versatility makes pseudopods essential for the survival and adaptability of many protists.

No, they do not. Because they have such a thin Cell Membrane, all the nutrients they need can be absorbed through diffusion or active transport.

An organism that eats protists or animals is called a predator.

The most common 'S' algae used in single protein supplements is Spirulina. This blue-green algae is renowned for its high protein content, containing all essential amino acids, and is also rich in vitamins, minerals, and antioxidants. Spirulina is often marketed for its potential health benefits, including boosting energy and supporting immune function. Its cultivation is sustainable, making it a popular choice for plant-based protein sources.

Diatoms and dinoflagellates are classified within the protist kingdom rather than the plant kingdom because they exhibit distinct characteristics that set them apart from true plants. While they are photosynthetic and share some similarities with plants, they lack certain features typical of plants, such as true roots, stems, and leaves. Additionally, their cellular structures, life cycles, and modes of reproduction differ significantly from those of plants, further justifying their classification within the protists.

Structures for movement, such as cilia, flagella, and pseudopodia, enable protists to navigate their environments effectively, which is crucial for survival. These structures help them find food by allowing them to move toward nutrients or away from harmful conditions. Additionally, movement aids in escaping predators and facilitates reproduction by enabling the protists to reach suitable mating partners. Overall, these adaptations enhance their ability to thrive in diverse habitats.

Protists often experience a peak production day due to optimal environmental conditions, such as increased nutrient availability, favorable temperatures, and sufficient light for photosynthesis. After this peak, factors like nutrient depletion, changes in temperature, grazing by predators, or unfavorable light conditions can lead to a decline in their populations. Additionally, competition among species for resources may also contribute to this decline. Ultimately, these dynamics reflect the balance of ecological interactions in their environment.

Pseudopodia move when an amoeba cell has to move or has to intake food particles from its surroundings.

The pseudopodia move in a very slow and planned manner.

One of the pseudopodia go along the left of the food particle and the other one goes left.

they meet after the object and then slowly swallow it.

its is very slow but effective way of taking in food.

no

No

No, it is not. Protists are eukaryotic organisms.

The two main jobs of an Amoeba are feeding and reproducing. They feed by engulfing food particles through a process called phagocytosis, and they reproduce asexually by simple cell division called binary fission.

i know some types of plankton eat diatoms and so do sponges,jellyfish and crabs and ther is still many more things that eat diatoms

Your question is not very clear. Microbes can be killed by radiation and heat. It depends on the amount of each and the duration. Viruses are not considered to be microbes but are infectious particles. They can also be inactivated by heat and radiation, especially UV light, but not by cold.

The paramecium has a stiffer cell membrane than the amoeba.

assuming all other systems normal...check for blend door functionality....a haynes type manual will help locate etc...but a local library should have professional shop manuals available in the REFERENCE section for free...make copies of the appropriate sections...read up and good luck :) Blend door (fresh air intake to cabin) not closing.

They have

Cell membranes, contractile vacuoles, cytoplasm, nucleus, Food vacuoles, and pseudopods.

They also have ribosomes, mitochondria, vesicles, endoplasmic reticulum, Golgi apparatus, cytoskeleton, lysosomes, and centrioles, but you can't really see them.

The cell is like the border, because it doesn't have cell walls. The contractile vacuoles collects water and throw it out of the cell. The cytoplasm is the body. The food vacuoles happen when the pseudopods fuse around food. The food is broken down in the food vacuole. The psuedopods are used to move and feed. They are created when the cytoplasm moves around and the rest follows.

Amoebas engulf their food by surrounding it with their cell membrane to form a food vacuole. Then, they release digestive enzymes into the vacuole to break down the food into nutrients that can be absorbed by the amoeba's cell. Once the nutrients are absorbed, the remaining waste is expelled from the cell.

An amoeba feeds by engulfing food particles through a process called phagocytosis. It surrounds the food particle with its cell membrane to form a food vacuole, which then fuses with lysosomes to digest the food. The nutrients are then absorbed into the cytoplasm for energy and growth.
