Answer:
Chloroplasts
Explanation:
Chloroplasts are found in cells of leaves and green parts of the stem. They contain green pigment called chlorophyll which makes photosynthetic cells to appear green. They are sites of photosynthesis. Chlorophyll traps light energy from the sun. The energy is used to drive the manufacture of sugars from carbon dioxide and water, a process called photosynthesis.
Answer: Option D
After load is the force the ventricles must overcome to eject blood into their respective arteries.
Explanation:
Afterload is the pressure or force the heart must overcome to release blood to the arteries during systole. It is proportional to the average arterial pressure. After load is also proportional to the mean systolic blood pressure measured in millimeters of mercury. It I'd a determinat of cardiac output and cardiac output is the product of stroke volume and heart rate.
Answer:
The correct answer will be option-C.
Explanation:
Photosynthesis is a complex process which converts light energy into chemical energy which is used to form the glucose molecule. Photosynthesis occurs in two stages: light-dependent and light-independent reaction.
The light-dependent reaction is the reaction which takes place in the sunlight and converts light energy to chemical energy in ATP and NADPH molecules.
The light-dependent begins when photosystem absorbs light energy which causes the excitation of the electrons provided by chlorophyll molecule. The excited electrons get accepted by electron acceptor molecule and a chain of electron flow begins called electron transport chain.
This creates a scarcity of electron in photosystem which causes hydrolysis of the water molecule as a result oxygen gas is released. The electron flow leads to the synthesis of ATP molecules through chemiosmosis.
Thus, Option-C is the correct answer.
