What is color of Paramecium?

Paramecium is typically colorless or translucent because it lacks pigmentation. Its color can appear slightly gray or greenish due to the food vacuoles containing algae or other microorganisms that it consumes.

Is Golgi appartus present in paramecium?

A paramecium is a single-celled organism, with its own set of organelles. It lacks most of the organelles most cells in humans and other multicellular creatures, including the golgi body.

How do protists move?

Ways that protists move:

  • flagella
  • cilium
  • pseudopod

Some protists don't move at all.

It uses its flagella. Some like the ameoba don't have a flagella but can move around with their body

How do diatoms shape help them survive?

Desiccated crystals or fibrils stick to surfaces when they are hydrated and when they contract they move the diatom along Centric diatoms ( marine) have radial symmetry in valve view and lack rapines and pseudoraphes . The outline of centric diatoms is usually circular, oval, or elliptical.

Octet rule for diatomic elements?

In diatomic elements, such as hydrogen (H2) or oxygen (O2), each atom follows the octet rule by sharing electrons to achieve a stable electron configuration. This results in a full outer shell of electrons with a total of 8 electrons, satisfying the octet rule. The sharing of electrons allows the diatomic molecule to be stable.

What is the methods of locomotion of Closterium?

1Closterium move in a somersaulting motion by secreting mucilage(2Mucilage is a thick gluey substance produced by most plants and some microorganisms) from alternating ends of the cell. 2http://en.wikipedia.org/wiki/Mucilage 1http://silicasecchidisk.conncoll.edu/LucidKeys/Carolina_Key/html/Closterium_Main.html

What do protist eat?

Protists can have a diverse range of feeding strategies, including photosynthesis (autotrophic), consuming organic material (heterotrophic), or a combination of both (mixotrophic). Some protists can engulf food particles through phagocytosis, while others can absorb nutrients from their surroundings.

Why do i see accidents and Dead bodies?

It could be due to experiencing trauma, stress, or anxiety, which can lead to intrusive thoughts. It's important to take care of your mental health and seek support from a therapist or counselor to address these distressing experiences. Practicing mindfulness and relaxation techniques may also help manage these thoughts.

What do protista eat?

Protists have diverse feeding habits. Some protists are autotrophic, meaning they can produce their own food through photosynthesis. Others are heterotrophic, meaning they obtain nutrients by consuming other organisms or organic matter. Some protists are mixotrophic, combining both autotrophic and heterotrophic feeding strategies.

What kingdom does a paramecium belong in?

Paramecium belongs to the protista kingdom, due to the fact that it is a protist...

Where does a diatom live?

Diatoms are a type of algae that can be found in various aquatic environments, including oceans, lakes, rivers, and even in damp soil. They are typically found in environments with high levels of nutrients and sunlight, as they rely on photosynthesis for energy.

What are some characteristics of elements?

The five elements have been selected and numbered by the Chinese. The characteristics why they have been chosen for example it's because they are the basic things in nature. Every element has it's own characteristics. As to texture, molecular hardness, weight, and physical characteristics.

How do amoebas grow?

Amoeba is a protozoan animal that is unicellular microscopic and found in fresh and marine water. It is also a endoparasite. In amoeba only asexual reproduction takes place and is of three types. 1 Binary fission: takes place in favourable conditions( when enough food and adequate temprature is avialable) just like mitosis completed in half an hour. During binarry fission amoeba stops feeding pseudopodia contract, but not dissapear. Contractile vacoule goes to one daughter cell and in second new c.v. is formed. Cytoplasm content of daugher amoeba just after division is near about equal to parent amoeba. 2 By sporulation: not found in amoeba proteus but found in other species of amoeb. Takes place in unfavourable conditions. The cell form 500-600 chromatin granules which undergo sporulation in favourable conditions and 250-300 spores are relased which become amoeba. 3 By encystment:takes place under unfavourable conditions, about 500-600 amoeba are formed. RESPIRATION: amoeba is aerobic. Respiration system is absent. Respiration takes place by diffusion through general body surface. NUTRITION: It is holozoic, ingest food by phagocytosis Digestion is intracellular, takes place in food vacoule. Digestive enzyme released from lysosome. Trypsin and amylase are also found. EXCERETION: amoeba is ammonotelic but dicarbonyl urea crystals are also found. Exceretion takes place through general body surface.

Is malaria harmful?

Yes, malaria is a serious and sometimes life-threatening disease caused by a parasite that is transmitted to humans through the bites of infected mosquitoes. It can lead to symptoms such as high fever, chills, and flu-like illness, and can be fatal if not treated promptly.

Do daphnia like light?

Daphnia are phototactic, meaning they are attracted to light. However, prolonged exposure to bright lights can stress them and disrupt their natural behaviors. It's important to provide them with a light-dark cycle that mimics their natural environment for optimal health and wellbeing.

How do amoebas react to heat and cold?

I know that if it gets too cold or too hot the amoeba will try to make away from it. If they do not move fast enough they will die because it is too cold or hot.

I'm only in grade 8 so my answer is not that sophisticated.

Which unit of measurement is most practical for measuring an amoeba?

Micrometers (µm) are the most practical unit of measurement for measuring an amoeba, as they are typically between 10-50 µm in size. This unit allows for precise and accurate measurements of these small organisms.

How do Amoeba react to danger?

Animals like plankton feeders (mussels and water fleas) eat amoeba. secrete certain chemicals and ward off their enemies. They also use their pseudopods to avoid predators. eg. a type of amoeba releases microcysts and macrocysts to defend itself.

How do you deal with excess stock?

== == From my understanding, excess stock can have several issues. First of all it wastes valuable space which can be used more efficiently running other things. Secondly, excess stock can mean that the company may suffer from wastage, as the stock can depreciate, or if the stock is a food product, it can expire. It would be best to ensure that stock is kept to a sustainable level for any organisation. If there are excess, it can be sold for extra cash. Holding excess stock is a waste, and if sold can contribute to cash if needed. What is important is to have a correct level of stock in a company. Maybe one should practice some Just In Time Systems.

Will algae harm my skin?

Algae in cosmetics is generally safe for skin and can offer various benefits, such as hydration and antioxidant protection. However, some individuals may be sensitive or allergic to certain types of algae, so it's always recommended to do a patch test first before using algae-based skincare products.

Are rhizopoda sarcodina animal-like or plant-like?

Rhizopoda Sarcodina are animal-like organisms. They are part of the protist kingdom and exhibit characteristics such as heterotrophic nutrition and typically motile.

What is the function of the cellular nucleus?

It controls the cells by giving it instruction.

Answer

The nucleus is the spherical or ovoid compartment of a cell, which contain the chromosomes and associated molecules that control the characteristics for growth of cellular reproduction. Chromsomes are made of DNA, and contain genes which hold the organisms genetic code. The code is transmitted by RNA to the cytoplasm of the cell where enzymes are made.

Where do protists live?

Protists can be found in various environments such as freshwater, saltwater, soil, and inside other organisms as parasites. They are diverse and can adapt to different habitats, ranging from oceans to lakes, and even in the digestive systems of animals.

Why do algae and fungi shift to the sexual mode of reproduction before the onset of unfavorable conditions?

due to unfavourable conditions they may not be able to go through asexual reproduction,so to providi resistance againsts these conditions they under go sexual reproduction.here there comes diversity and variationswhere genes become strong and can live,survive through these conditions
