What are 2 differences between unicellular and multicellular organisms?
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Which characteristics of all living organisms are related to gathering and using energy?
Answer. Answer: Several primary characteristics or functions are shared by all classes of living organisms: order, sensitivity or reaction to stimuli, reproduction, adaptation, growth and development, control, homeostasis, and energy processing.
What is the true for cyanobacteria?
Blue green algae (BGA) also known as cyanobacteria are photosynthetic prokaryotes. Many of them form symbiotic association with fungi and green plants. According to Bergey’s classification they are oxygenic phototrophic bacteria. Many members have the ability to fix the atmospheric nitrogen in the soil.
What is the difference between cyanobacteria and algae?
Both green algae and cyanobacteria are photosynthetic organisms that produce their own food by photosynthesis. The main difference between green algae and cyanobacteria is that green algae contain chloroplasts whereas cyanobacteria do not contain chloroplasts in their cells.
Is cyanobacteria oxygenic with nitrogenase?
Thus, the correct answer is option A. i.e., oxygenic with nitrogenase. Note: Cyanobacteria are microscopic and rich in chemical diversity and they use photosynthesis to make their own food in the presence of oxygen so they are oxygenic.
In which organisms enzymes are absent?
Without enzymes no biochemical reaction can take place in any living cell at biologically significant rate. Virus are non living, crystallizable entities. Hence, virus do not have any enzymes of their own but make use of enzyme machinery of the host for their replication.
What is enzyme km?
For practical purposes, Km is the concentration of substrate which permits the enzyme to achieve half Vmax. An enzyme with a high Km has a low affinity for its substrate, and requires a greater concentration of substrate to achieve Vmax.”
Where are enzymes present in plants?
In plants as well as animals, enzymes are present in all living cells.
What is the role of enzymes in plants?
Enzymes, in turn, catalyse important biochemical reactions for rhizobacteria and plants, stabilize the soil by degrading wastes and mediate nutrient recycling . The available enzymes inside soil could originate from plants, animals or microbes (bacteria or fungi).
What are the sources of enzymes?
All forms of life live by enzymes and also produce enzymes. As a result, enzymes can be obtained from three different sources: plants, animals, and microorganisms. Some commercial enzymes such as papain, bromelain (bromelin) ficin, and malt diastase are derived from plant sources.
What are the benefits of enzymes?
Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
