Protists

Lysosome contain digestive enzymes for almost all type of organic material. If their covering membrane breaks as it happens during injury to cell, the digestive enzymes will spill over cell content and digest the same. As lysosomes are organelles which on bursting can kill cells possessing them ,they are called suicide sacs.

Examples of roundworm parasites include Ascaris lumbricoides, which can cause intestinal infections in humans, and hookworms like Ancylostoma duodenale and Necator americanus, which infect the intestines and may cause anemia. Trichinella spiralis is another roundworm parasite that can be ingested by consuming undercooked meat, leading to trichinosis.

Amoeba obtains its nutrition in a heterotrophic mode. Both the anabolic and catabolic functions are carried out in the same cell. Amoeba feeds on plankton and diatoms present in water. It can form arm- like structures called pseudopodia, extending from any part of its body as it is shapeless. When it senses food in its surroundings it extends its pseudopodia in that direction and moves towards it. then it engulfs the food with its pseudopodia. When the food enters its body the amoeba forms a food vacuole around it which contains certain enzymes to digest the food. When the food is digested the unwanted waste is released through its body surface.

Proteins are made in cells at structures called ribosomes. Ribosomes can be found in the cytoplasm of the cell or attached to the endoplasmic reticulum. These organelles are responsible for translating the instructions carried by messenger RNA (mRNA) into protein molecules.

Organelle 11 likely plays a critical role in the specific function of the cell, such as energy production, protein synthesis, or waste management. Without organelle 11 functioning properly, the cell may not be able to carry out its normal activities and maintain its overall health and functionality.

The ileum refers to the last part of the small intestine, and is composed of many cells.

A wolf is made up of eukaryotic cells. Eukaryotic cells have a nucleus and other membrane-bound organelles, which are characteristics found in the cells of multicellular organisms like wolves.

The telephone country code for the United Arab Emirates is +971, and mobile numbers in the UAE begin with +971 5. (You must drop the trunk prefix 0 from the UAE domestic telephone number to put it into international format.)

To dial a mobile number in the UAE using a phone card, follow the instructions on the card, or follow the voice prompts to enter an international telephone number. You may need to use an international access prefix to enter the number. The most commonly used prefix is 00, but North America (USA, Canada, etc.) uses 011. The prefix you need to use for the calling card may depend on where the calling card provider is based, and may be different from the prefix you would use if you were dialing the call directly from your location.

Yes, excitable cells like neurons are more permeable to sodium ions than potassium ions. This selective permeability is due to the presence of more sodium channels compared to potassium channels in the cell membrane, allowing sodium to flow into the cell more readily during an action potential.

Cnidarians (Phylum Cnidaria; stinging animals, including sea anemones) use their stinging cells (properly called cnidocytes, Latin for "stinging chamber") in order to capture prey. The cnidocytes are basically a cellular-sized harpoon. When prey bumps into the cnidocyte, a trigger mechanism is activated and the harpoon rushes out. Some species add poisons for good measure. The tentacles are then able to draw food to the mouth, where it is digested and the waste expelled through the mouth (yes, they use their mouth as an anus).

The four components of blood are red blood cells (cells), white blood cells (cells), platelets (cell fragments), and plasma (liquid). Plasma is the liquid component of blood that carries the cells and platelets throughout the body.

The song "Tainted Love" by Soft Cell was released in 1981. It became a hit and is still popular today.

Paramecium reproduces asexually through binary fission, where the cell divides into two identical daughter cells. They can also undergo conjugation, a form of sexual reproduction, where genetic material is exchanged between two individual cells.

Stentor are Protists from the phylum Ciliophora.

Measles is a viral infection caused by the measles virus, which primarily infects and replicates in immune cells such as T lymphocytes and macrophages in the respiratory system.

Akinetes in Spirogyra serve as dormant cells that are formed during unfavorable conditions like extreme temperatures or nutrient scarcity. These akinetes can remain dormant until conditions improve, allowing Spirogyra to survive and reproduce when conditions are more favorable.

A contractile vacuole helps amoebae and paramecium regulate the water content within their cells by periodically expelling excess water to prevent them from bursting due to osmotic pressure. Without a contractile vacuole, these organisms would be vulnerable to cellular damage from fluctuations in hydration levels and could potentially die from osmotic stress.

The four different branches evolved at different times, but have the same characteristics.

Protists that are plantlike include algae, such as diatoms, green algae, red algae, and brown algae. These protists perform photosynthesis to obtain energy, and they can contain chlorophyll or other pigments that give them a green, red, or brown coloration.

Spirogyra is a type of green algae, which is plant-like. It is a filamentous organism that performs photosynthesis, like plants. It differs from animals and fungi in its cellular structure and mode of nutrition.

Ensure the pregnant algae eater has a well-balanced diet with plenty of vegetables and algae wafers. Provide hiding spots in the aquarium to reduce stress during pregnancy. Monitor water quality closely and be prepared to separate the female if she displays signs of distress or aggression.

Some protists can respond to stimuli such as light, temperature, chemicals, touch, and gravity. These responses may help them navigate their environments, find sources of food, avoid predators, or reproduce effectively.

Protists can grow in a variety of habitats such as freshwater, marine environments, soil, and even inside other organisms as parasites. They are commonly found in water bodies, including ponds, lakes, and oceans, where they play important roles in the ecosystem.

Plasmodium, which cause malaria and live in the digestive tract of mosquitoes until it is transferred to humans. Trypanosomes live in harsh dry areas and cause African Sleeping Sickness and they also have a parasitic relationship with tsetse fly. Trichonympha agilis lives in the digestive tract of termites and they help break down the wood matter and convert it into energy for the termite.

Heterogeneous grouping refers to a diverse mixture of different types of unicellular colonial and multicellular eukaryotes, such as slime molds, brown algae, and diatoms. These groups share the characteristic of being eukaryotic but differ in their cellular structures, organization, and modes of reproduction.
