A vacuum cleaner helps collect waste that is left behind on the floor. Some vacuum cleaners even suction up liquids. The vacuum cleaner could represent which organelle in the cell?
Answer:
lysosome
Explanation:
It deals with food, and like a vacuum, stores things
A vacuum cleaner helps collect waste that is left behind on the floor. Some vacuum cleaners even suction up liquids. The vacuum cleaner could represent lysosomes.
What is lysosomes?Lysosomes are defined as membrane-enclosed organelles containing a variety of enzymes capable of degrading all sorts of biological polymers, including proteins, nucleic acids, carbohydrates, and lipids.
It can also be defined as sphere-shaped vesicles or sacs containing hydrolytic enzymes capable of breaking down nearly all types of biomolecules.
Lysosomes are hydrolytic enzyme-containing cell organelles. Hydrolytic enzymes can degrade undesirable cell components such as proteins, lipids, and carbohydrates, resulting in cell waste.
Vacuum cleaner is defined as a suction device used to remove dirt off floors, upholstery, drapes, and other surfaces It is usually powered by electricity.
Thus, a vacuum cleaner helps collect waste that is left behind on the floor. Some vacuum cleaners even suction up liquids. The vacuum cleaner could represent lysosomes.

Place the terms into the correct column that describes the reactions of photosynthesis.
Answer:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
Explanation:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
The light-dependent reactions involve both photosystems I and II along with the electron transport system. ATP is synthesized in this reaction, so ATP synthase is also included.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The light-dependent reaction of photosynthesis occurs in the thylakoid membrane. Sunlight and water are the reactants of this reaction. The products of this reaction are NADPH, ATP, and oxygen.
Light-independent reaction involves the Calvin cycle. It occurs in the stromal part of the chloroplast. The reactants of this reaction are carbon dioxide, ATP, and NADPH while the products are glucose, NADP+, and water.
Therefore, the difference between light-dependent reaction and light-independent reaction is well described above.
