Question

by which process does gaseous exchange takes place during external respiration in plants and which part of the leaves carry it out and how? ​

Answer 1

Answer:

The leaves of plants have tiny pores on their surface which are called stomata. The exchange of gases in the leaves during respiration takes place through stomata.

This happens as follows: Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process of diffusion. This oxygen is used in respiration in cells of the leaf. The carbon dioxide produced during diffuses out from the leaf into the air through same stomata.

The photosynthesis reaction makes glucose and the respiration reaction break it down. In photosynthesis, the energy which goes into the reaction is light energy.

Answer 2

Respiration in plants

Explanation:

• During respiration, little amount of gas exchanges happens inside the various pieces of the plants. In this manner, each part deals with its own vitality necessities.  
• Roots, stems, and leaves of plants trade gases for respiration independently. As we as a whole know, leaves have small pores called stomata, which is utilized for the trading of gases. The oxygen, taken in through stomata is utilized by cells in the leaves to separate glucose into carbon dioxide and water.  
• Leaves include minor pores referred to as stomata. The trading of gases happens by means of stomata through the procedure of dispersion. Every stoma is constrained by Guard Cells. The opening and shutting of the stoma help in the trading of gases between the air and the inside of leaves
• The leaves of plants have modest pores on their surface which are called stomata. The trading of gases in the leaves during breath happens through stomata.  
• This occurs as follows: Oxygen from the air goes into a leaf through stomata and arrives at all the cells by the procedure of dispersion. This oxygen is utilized in breath in cells of the leaf. The carbon dioxide delivered during diffuses out from the leaf into the air through same stomata.  
• The photosynthesis response makes glucose and the breath response separate it. In photosynthesis, the vitality which goes into the response is light vitality. In breath, the vitality which turns out is substance vitality.
