3) C. Stomata, as I explained in my previous answer.

4) B. Nonvascular, low-hanging plants living in moist environs don't have to fight gravity nearly as much as tall ones do. So they needn't highly developed vessels to transport to their tips

5) B. Gravity, see above. The higher trees/plants grew, the further their apical structures were from ground water sources, so the lignin-supported, strong vascular tissue (phloem) allows the transport of water against gravity, using a capillary method (benefiting from the adhesive effect of water molecules).

The multicellular organism that can produce their food by using the sunlight and transforming them into a chemical reaction is called plants.

3. The correct answer is:

Option C. Stomata.

  • They are the diminutive openings and closing present on the leaves.

  • They regulate the actions of the gas and water vapours.

  • The interchange of gases like oxygen, carbon dioxide and water vapour takes place through the stomata.

4. The correct answer is:

Option B. Non-vascular.

  • Non vascular plants are called bryophytes and are mainly confined to wet areas.

  • They lack the vascular arrangement that is they do not have tissues for shipping of the water and nutrients.

  • Therefore, they live close to the soil surface and thrive in moist areas to maintain the water needed.

5. The correct answer is:

Option B. Gravity.

  • Lignin is the central supporting and adaptive characteristic of the plants.

  • They support the plant in structural organisation and enables them to grow tall.

  • It lines the water transport system and provides mechanical assistance to the plant tissues to rise against gravity.
