BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337116 Which factor is not limited to normal conditions for photosynthesis?

1 Chlorophyll

2 Temperature

3 Air availability

4

C O_{2}

concentration

Explanation:

Chlorophyll is not counted as a limiting factor. It is present inside plants and hence, is not an external factor. Light, temperature, $C O_{2}$ (air availability) are major external limiting factors.

337117 Which of the following is the major limiting factor for photosynthesis?

1 Carbon dioxide

2 Water

3 Light

4 Temperature

BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337118 For photosynthesis, beyond 0.05% of $C O_{2}$ concentration in environment $C O_{2}$

1 Can be damaging over longer periods

2 Can be beneficial over longer period

3 Can be damaging instantly

4 Can be beneficial instantly

Explanation:

Beyond 0.05% of $C O_{2}$ concentration, $C O_{2}$ can become damaging over longer periods.

BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337174 As compared to plants in tropical regions, plants in ___ have a lesser temperature optimum for photosynthesis.

1 Desert

2 Thermal vents

3 Temperate regions

4 All of the above

BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337119 Statement A :
$C_{3}$ plants respond to higher $C O_{2}$ concentration leading to higher productivity has been used for some greenhouse crops such as tomatoes and bell pepper
Statement B :
The $C_{3}$ and $C_{4}$ plants respond equally to $C O_{2}$ concentrations

1 Statement-A is correct but Statement-B is incorrect

2 Statement-A is incorrect but Statement-B is correct

3 Both the statements are correct

4 Both the statements are incorrect

Explanation:

$C_{3}$ plants respond to higher $C O_{2}$ concentration by showing increased rates of photosynthesis leading to higher productivity has been used for some greenhouse crops such as tomatoes and bell pepper. They are allowed to grow in carbon dioxide enriched atmosphere that leads to higher yields.
