Answer 2

Here the given sentences are A) I, II are true

Explanation:

The sentences given above both are true.

• The plants breakdown the unwanted substances at a much lower rate as distinguished to animals because the metabolism of plants is comparatively very much slower than the metabolism of animals.
• The waste products of a plant are CO2, water vapor, and oxygen. While carbon dioxide and water-gas are unwanted products of respiration, oxygen is an unwanted material of photosynthesis. These unwanted products are removed through stomata in layers and lenticels in stems and are released to the air.
• Gaseous garbage is excreted through stomata and lenticels.
