Consider the following assertions in relation to photosynthesis: 1. O...
The correct answer is option 'B': 2 Only.
Explanation:
1. Only oxygen is formed from the process of photosynthesis.
This assertion is incorrect. Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. During photosynthesis, oxygen is indeed released as a byproduct, but glucose is the main product. Oxygen is produced when water molecules are split during the light-dependent reactions of photosynthesis. Carbon dioxide from the atmosphere is also used during the light-independent reactions to produce glucose. Therefore, it is not accurate to say that only oxygen is formed from the process of photosynthesis.
2. In addition to the leaves, the other green parts of plants also carry out photosynthesis.
This assertion is correct. While leaves are the primary photosynthetic organs of plants, other green parts of plants such as stems and branches can also carry out photosynthesis to a certain extent. This process is known as stem photosynthesis. In some plants, the stems contain chlorophyll and can produce glucose through photosynthesis. However, the rate of photosynthesis in stems is generally lower compared to leaves. Leaves have specialized structures called stomata that allow for gas exchange and facilitate photosynthesis more efficiently. Nevertheless, it is true that the other green parts of plants can contribute to the process of photosynthesis.
In conclusion, only assertion 2 is correct. While photosynthesis does produce oxygen as a byproduct, it is not the only product. Additionally, in addition to leaves, the other green parts of plants can also carry out photosynthesis to some extent.
