Question

In plants, the gaseous exchange take place ina) Stomatab) Rootsc) Stemsd) Lenticlesa)aand bb)aand dc)band dd)band cCorrect answer is option 'B'. Can you explain this answer?

Answer

Yes we all know stomata main work is to exchange gases by opening and closing itself and lenticles are modification for exchange of gas

Answer

Gaseous exchange in plants occurs through specialized structures called stomata and lenticels.

Stomata:
- Stomata are tiny pores present on the surface of leaves and stems.
- They are surrounded by two specialized cells called guard cells that regulate their opening and closing.
- During photosynthesis, stomata open to allow the entry of carbon dioxide (CO2) and the release of oxygen (O2) produced during the process.
- During respiration, stomata open to allow the entry of oxygen and the release of carbon dioxide produced during the process.

Lenticels:
- Lenticels are small, porous structures present on the surface of woody stems and roots.
- They are responsible for the exchange of gases between the internal tissues and the external environment.
- Lenticels differ from stomata in that they lack guard cells and are non-regulated.
- They are more prominent in woody plants, where the exchange of gases in the bark is necessary for the survival of the plant.

Therefore, the correct option is (b) a and d, as gaseous exchange in plants occurs through both stomata and lenticels.

Answer

Stomata are present on leaves to help in photosynthesis and respiration. Gaseous exchanges play a very important role delivering sterling results to the users .
lenticels are small pores that are found o stems. they also help in the exchange of useful gases throughout the lifecycle of the plants.

Answer

Stomata and lenticles

Answer

Stomata and lenticles r the chief respiratory organ in plants

Answer

Êxçhãnge of gases in róøt of a plant takes place by the process of diffusion. During diffusion, oxygen diffuses into the root hairs and passes into the root cells, from where the carbon dioxide moves out into the soil.

Answer

Bcoz Lenticles have numerous pores which carry out gaseous exchange in plants especially in tap root system plants.

Answer

A and d

Answer

D

Answer

Stomata is similar to a pore found in the epidermis of the leaves , stem and other organs that are used to control gas exchange .They allow gas exchange of CO2, water vapour and O2 to move rapidly in and out of the leaves .
A lenticels is a spongy area present in the Woody surface of stems.

Answer

Because the exchange of gases takes place through pores and these pores are stomata(present on leaf) and lenctiles(present on the bark of the stem) but exchange of oxygen and CO2 also takes place through root.

Answer

Its stomata and lenticle(b)

Answer

The answer  is wrong because in lenticles gaseous  exchange  does not  occur rather  there is removal of water in lenticles and in special roots such as pnematophores respiration occurs  so  there is gaseous     exchange  so the correct  answer  should be A and B

Answer

Stomata
