Solanaceae flowers are bisexual, actinomorphic, pentamerous, epipetalous and possess a superior ovary.
Photosynthesis In Higher Plants
Select the correct sequence of experiments that led to a gradual understanding of photosynthesis in green plants.
A Absorption spectra of chlorophyll a and b → production of glucose → release of oxygen → role of air B Role of air → release of oxygen → production of glucose → absorption spectra of chlorophyll a and b C Release of oxygen → production of glucose → absorption spectra of chlorophyll a and b → role of air D Production of glucose → role of air → release of oxygen → absorption spectra of chlorophyll a and b

The understanding of photosynthesis progressed from proving the role of air, to oxygen evolution, carbohydrate formation and finally pigment absorption studies.
Body Fluids And Circulation
The number of action potentials generated by sino-arterial node (SAN) in a healthy human is _______ per minute.
A 28 – 30 B 70 – 75 C 100 – 110 D 120 – 140

The sinoatrial (SA) node normally generates 70–75 action potentials per minute and acts as the natural pacemaker of the human heart.
Photosynthesis In Higher Plants
How many turns of Calvin cycle are required for the formation of three molecules of glucose?
A 6 B 3 C 1 D 18
Show explanation
Bookmark
Try again
Six turns of the Calvin cycle produce one glucose molecule. Therefore, three glucose molecules require 18 turns.
Body Fluids And Circulation
Which of the following statements is incorrect?
A Blood coagulates in response to an injury B Blood clot consists of fibrins C Fibrin is produced from fibrinogen D Fibrinogen is produced from fibrin
Show explanation
Bookmark
Try again
Fibrin is formed from fibrinogen during blood clotting, not the other way around.
