Do protists have respiration?
Cellular respiration in the kingdom is primarily an aerobic process (with oxygen), but some protists, including those that live in mud below ponds or in animal digestive tracts, are anaerobes (without oxygen).
What organisms use cellular respiration?
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists.
What organisms dont perform cellular respiration?
All organisms contain one or more cells, and cells need usable energy to carry out their functions. Because of this, all organisms (except certain types of bacteria and yeasts) perform cellular respiration.
How do protists do respiration?
They require oxygen for the process of respiration. These types of protists are called obligate aerobes and the respiration occurs in aerobic respiration, while in some cases like parasitic protists they do not require oxygen thus respiration occurs through anaerobic respiration. These protists are called anaerobes.
How do protists obtain their energy?
They obtain energy from sunlight. Their cells provide food for many other organisms. These protists also pro- duce oxygen, which is beneficial to many other organisms. Both of these roles are similar to those played by plants.
How do protists reproduce?
Protists reproduce by a variety of mechanisms. Most undergo some form of asexual reproduction, such as binary fission, to produce two daughter cells. In protists, binary fission can be divided into transverse or longitudinal, depending on the axis of orientation; sometimes Paramecium exhibits this method.
Do plants use cellular respiration?
Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. 8. Plants have mitochondria and can perform cellular respiration.
Is cellular respiration needed by all organisms?
All living things use cellular respiration to turn organic molecules into energy. Cellular respiration is the chemical process of breaking down food molecules in order to create energy in the form of adenosine triphosphate (ATP).
Do protists use photosynthesis?
Protist cells Photosynthetic protists such as the various types of algae contain plastids. These organelles serve as the site of photosynthesis (the process of harvesting sunlight to produce nutrients in the form of carbohydrates). The plastids of some protists are similar to those of plants.
How do protists move and reproduce?
Motility. Some protists are not motile, but most protists are able to move about. Protists can move about in three ways: using pseudopods, flagella, or cilia, which are shown in Figure below. Many protists have flagella or cilia which they beat or whip about to move in their watery environment.
How do protists get their energy?
They obtain energy from sunlight. Their cells provide food for many other organisms. These protists also pro- duce oxygen, which is beneficial to many other organisms. Both of these roles are similar to those played by plants.
How do protists reproduce quizlet?
Most Protist reproduces asexually using binary fission, where a one Protist splits into 2 identical cells. Some Protist can reproduce by multiple fission where one Protist produces more than two other cells. Some Protist can reproduce sexually congregation where two cells are joined and trade genetic information.
Does cellular respiration occur in prokaryotes?
In Prokaryotes, cellular respiration mainly occurs within the cytoplasm of the cell. Similar to eukaryotes, cellular respiration in prokaryotes is carried out in three different stages: Glycolysis. Krebs cycle.
What type of cells perform cellular respiration?
Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on eukaryotic cells where the mitochondria are the site of most of the reactions.
What organisms perform cellular respiration and photosynthesis?
Plants carry out both photosynthesis and cellular respiration. They make their own food, and then break down those glucose molecules later, generating ATP to power their cellular processes.
How do protist cells reproduce?
Life Cycles Protists reproduce by a variety of mechanisms. Most undergo some form of asexual reproduction, such as binary fission, to produce two daughter cells. In protists, binary fission can be divided into transverse or longitudinal, depending on the axis of orientation; sometimes Paramecium exhibits this method.
What methods do protists use to reproduce?
Protists can reproduce asexually through binary fission, one nucleus divides; multiple fission, many nuclei divide; and budding. During both types of fission the organism replicates its nucleus and divides to form new organisms. Budding occurs when a new organism grows from the body of its parent.
How do protist reproduce?
Protists reproduce by a variety of mechanisms. Most undergo some form of asexual reproduction, such as binary fission, to produce two daughter cells. In protists, binary fission can be divided into transverse or longitudinal, depending on the axis of orientation; sometimes Paramecium exhibits this method.
What do all protists have in common quizlet?
What do all protists have in common? They have a nucleus and other complex organelles. They lack some characteristics that prevent them from being classified as plants,animals, or fungi.
Do all organisms go through cellular respiration?
All living cells must carry out cellular respiration. It can be aerobic respiration in the presence of oxygen or anaerobic respiration.
Do eukaryotes use cellular respiration?
Cellular respiration occurs in both eukaryotic and prokaryotic cells, with most reactions taking place in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes.
What organisms use cellular respiration and photosynthesis?
Plants carry out both photosynthesis and cellular respiration. They make their own food, and then break down those glucose molecules later, generating ATP to power their cellular processes.
What type of reproduction do protists use?
The typical mode of reproduction in most of the major protistan taxa is asexual binary fission.
How can protists reproduce How do they get their energy?
Most protists reproduce primarily through asexual mechanisms according to Simpson. This can include binary fission, where a parent cell splits into two identical cells or multiple fission, where the parent cell gives rise to multiple identical cells.
How do protists obtain energy?
Protists can be classified by their way of getting energy. Some protists capture sunlight and convert it to usable energy. Another group of protists gets its energy from eating other organisms. A third group gets energy by absorbing materials and nutrients from its environment.

In Prokaryotes, cellular respiration mainly occurs within the cytoplasm of the cell. Similar to eukaryotes, cellular respiration in prokaryotes is carried out in three different stages: Glycolysis. Krebs cycle.

Does cellular respiration occur in all organism types?
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals. Cellular respiration begins in the cytoplasm of cells. It is completed in mitochondria.
