Question

How does exchange of gases take place in plants?​

Answer 1

Answer:

In plants, the exchange of gases takes place through stomata. Each of the stomata is surrounded by two guard cells, and these cells contain chloroplasts. A respiratory opening is found under each stoma, and the process of opening and closing of stomata depends on the presence of sugar and starch in the guard cells.

Answer 2

$\large \sf \: here \: \: is \: \: your \: \: answer :$

As we know,

Plants intake carbon dioxide

and give us Oxygen

$\\ \large \sf \: leaves \: \: are \: \: the \: \: site \: \: of \: \: rispiration$

Explanation

Plant leaves have tine pores ,

• Under a micro scope

You will observe tiny pores covered with 2 bean like structures called as Gaurd Cells

Gaurd Cell swell up when water enters in and plant takes carbon dioxide from air .

• This water comes through roots from soil

In Other words

Detailed explanation

During the process of photosynthesis

• Plant absorbs water from roots

In the root , their are semi permeable membranes

• Water moves acroos these membranes by the process od osmosis

When water reaches the leaf due to osmosis Gaurd cells of tiny pores called as stomata swells

• This opens the pores and plant inhails carbon dioxide

Chlorophyll absorb sunlight and glucose + oxygen is formed .

• Oxygen is also released from tiny pores called stomata .

Stomata closes when water passes from gaurd cells and makes it to shrink
