The chloroplast and chromoplast considered the living components of plant cell because of their respective functions. The chloroplast is used for photosynthesis while the chromoplasts are responsible for the distinctive pigment in plants.
Whereas the crystals, starch grains and aleuronic grains consider non-living components because they do not carry such functions. The starch granules store some of the food made during photosynthesis.
Answer:
D. They allow the plant to synthesize glucose under hot conditions.
Explanation:
C4 and CAM photosynthesis strategies allow for plants to produce glucose in hot and dry conditions.
Plants such as cacti, which live in hot conditions, have the advantage from their C4 and CAM systems.
In contrast to C3 photosynthesis, C4 and CAM systems allow plants to get more CO2 from the air and help them conserve water.
This then allows them to efficiently create glucose with the CO2.
So, the correct answer is D.
The covalent bonds between the oxygen and the hydrogen atoms result from a sharing of the electrons. This is what holds the water molecules themselves together. The hydrogen bond is the chemical bond between the water molecules that holds the mass of molecules together.
Answer:
Closed system.
Explanation:
Robot is an closed system because there is no transfer of mass but transfer of energy occurs from robot to its surrounding. According to the definition of closed system, closed system is a type of system in which there is only transfer of energy occurs while in open system both mass and energy can be transferred from the system to their surrounding. So no mass transferred from the robot only energy in the form of mechanical energy is transferred.
Answer:
The correct answer is - True.
Explanation:
Degradative pathways are the pathways that provide energy for the anabolic reactions, these are catabolic reaction. An activator protein is a protein that enhance the transcription by binding to DNA.
A transcriptional activator are bind to the enhancers or promoter proximal elements. These are the the DNA binding proteins that regulates the transcription of the DNA molecule.
Thus, the correct answer is - true.
