Protozoa

The paramecium contains a vacuole called a contractile vauole. By contracting rhythmically, this specialized vacuole pumps excess water out of the cell. the control of water content within the cell is just one example of an important process known as homeostasis. Homeostasis is the maintenance of a controlled internal environment.

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.

No, protozoa is not a domain of life. Protozoa are a diverse group of single-celled eukaryotic organisms that belong to the domain Eukarya, along with plants, animals, and fungi. The three domains of life are Bacteria, Archaea, and Eukarya.

The vector for Plasmodium, the parasite that causes malaria, is the female Anopheles mosquito. These mosquitoes can transmit the parasite to humans through their bites during blood meals.

Amoebas use pseudopods, which are temporary bulges of their cell membrane, to move around. By extending and retracting these pseudopods, amoebas are able to crawl and engulf food particles.

A tooth amoeba is a one-celled organism that lives in the mouth or dental plaque, but it is not a common or recognized term in biology. It may refer to a hypothetical microorganism used in educational settings to represent the importance of dental hygiene and plaque formation on teeth.

Contractile vacuoles in paramecium are responsible for regulating water content within the cell by collecting excess water and expelling it from the cell via pulsations. The radiating canals help in the collection of excess water from various parts of the cell and channel it towards the contractile vacuole for expulsion, helping in osmoregulation to maintain cell volume and prevent bursting.

Yes, Euglena is a genus of single-celled flagellate eukaryotes, while euglenoids refer to members of the phylum Euglenophyta to which Euglena belongs. So, in a way, Euglena is a type of euglenoid.

Paramecium are not known to cause illness in humans. They are single-celled organisms commonly found in freshwater environments and are part of the planktonic community. While there are parasitic organisms related to Paramecium that can cause illness, Paramecium itself is not pathogenic to humans.

No, protozoans are a type of animal-like protists. Protozoans are consumers that can live in water, soil, or other organisms. While these organisms do not resemble animals, they are called animal-like because they are consumers and they share some characteristics with animals. Other types of protists are plantlike and fungus-like protists.

The amoeboid cells are haploid. In the sexual phase of the life cycle, two amoeboid cells fuse to form a zygote. New amoeboid cells are produced by meiosis.

Volvox colonies were first recorded by Dutch microscopist Antonie van Leeuwenhoek in 1700 and are widely studied as a genetic model of morphogenesis (how organisms develop specialized cells and tissues). Volvox also exhibit differentiation between somatic (non-sex cells) and reproductive cells, a phenomenon considered by some biologists to be significant in tracing the evolution of higher animals from microorganisms.

Trichomoniasis is not typically passed from mother to child during childbirth. However, in rare cases, it is possible for a pregnant woman to pass the infection to her baby during delivery, resulting in a condition called neonatal trichomoniasis.

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.

Photosynthesis is essential for Euglena's survival because it is the process by which Euglena produces food (glucose) using sunlight, water, and carbon dioxide. This food provides the energy needed for Euglena to carry out its life processes and functions. Without photosynthesis, Euglena would not be able to sustain itself and would eventually die.

Protozoans that cannot move are called sessile protozoans. These organisms are typically attached to a substrate and rely on external factors, such as water currents, to bring food to them.

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.

Water typically moves into protozoa by osmosis, as they are usually in a hypotonic environment. This helps maintain their internal water balance and prevents dehydration.

Volvox and paramecium are both types of microscopic organisms found in freshwater environments. They are both single-celled organisms that belong to the kingdom Protista and exhibit characteristics of eukaryotic cells. Both organisms are also capable of self-propulsion and feeding on organic matter.

The two types of amoeba-like protozoa that don't look like typical amoebas are radiolarians and foraminiferans. Radiolarians have intricate silica shells that give them a distinctive appearance, while foraminiferans have calcium carbonate shells with pores through which they extend pseudopods.

Plasmodium vivax is a protozoan parasite that causes malaria. Its life cycle involves both human and mosquito hosts. Trypanosoma gambiense is a protozoan parasite that causes African sleeping sickness. Its life cycle involves both human and tsetse fly hosts.

Chlamydomonas and euglena both have chloroplasts for photosynthesis to produce energy from sunlight. They both have flagella for movement, allowing them to swim and navigate their environments to find nutrients and light for photosynthesis.

Dinobryon is a colonial ciliate that reproduces asexually by binary fission, where the parent cell divides into two daughter cells. Over time, continuous asexual reproduction can lead to reduced genetic diversity within the population, making the species more susceptible to environmental changes and diseases. This lack of genetic variation can hinder the species' ability to adapt and evolve, ultimately affecting its long-term survival.

In an amoeba cell, lysosomes help in breaking down waste materials, old organelles, and engulfed food particles through a process called phagocytosis. They contain digestive enzymes that aid in the breakdown of these materials to be recycled or eliminated from the cell.

They make hollering and whooshing sounds, you just have to listen very closely.
