Which of the following statements regarding cell division is incorrect?
Mitosis produces genetically different daughter cells.
Meiosis is involved in sexual reproduction.
Cell division is essential for growth and repair in multicellular organisms.
Meiosis produces four daughter cells.
Which of the following is NOT a characteristic of meiosis?
Production of genetically identical daughter cells
Two rounds of division
Formation of haploid cells
Introduction of genetic variation
The Emerson enhancement effect and the Red drop phenomenon were crucial in uncovering the existence of:
Chemiosmosis
Two photosystems
Photophosphorylation
Cyclic photophosphorylation
Which experimental observations provided strong evidence for the presence of two distinct photosystems in photosynthesis?
Hill reaction
Blackman's law of limiting factors
Emerson effect and Red drop
Warburg effect
The sharp decline in photosynthetic quantum yield observed at wavelengths above 680 nm, known as the Red drop, suggests:
Chlorophyll a is not the only pigment involved in light absorption.
Photosynthesis ceases completely at wavelengths above 680 nm.
Chlorophyll a becomes inactive at wavelengths above 680 nm.
Far-red light is not utilized in photosynthesis.
If only chlorophyll a were present in plants, which phenomenon would be most prominently observed?
A pronounced Emerson enhancement effect
A pronounced Red drop effect
Increased photolysis of water
Increased photorespiration
In photosynthetic organisms, the Emerson enhancement effect is observed when:
Green light is used
Blue light is used
Red light is used alone
Red and far-red light are used simultaneously
Which of the following statements about reproduction is incorrect?
Sexual reproduction introduces genetic variation.
Asexual reproduction leads to genetically identical offspring.
Cell division is fundamental to both sexual and asexual reproduction.
Offspring produced via sexual reproduction are genetically identical to the parent(s).
Which process is NOT essential for sexual reproduction?
Meiosis
Gamete formation
Fertilization
Binary fission
During photorespiration, the oxygenation activity of the RuBisCo enzyme results in the production of:
One molecule of phosphoglycerate and one molecule of phosphoglycolate
Two molecules of phosphoglycolate
Two molecules of phosphoglycerate
One molecule of phosphoglyceraldehyde and one molecule of phosphoglycolate
