Do stomata close when there is a lack of water in soil or a lack of carbon dioxide in the atmosphere?

Biology
1 answer:
Arte-miy333 [17]3 years ago
5 0

<em>When water is abundant:</em>

-Temporal regulation of stomata is used:

Open during the day

Closed at night

- At night, there is no photosynthesis, so no demand for CO2 inside the leaf.

- Sunny day = demand for CO2 in leaf is high = stomata wide open.

- As there is plenty of water, plant trades water loss for photosynthesis products.

-  If the leaf's CO2 concentration is low, the stomata will stay open to continue fueling photosynthesis.

- High temperatures will also signal stomata to close.

- When limited water is available in the soil, plants try to prevent water loss.

Answer:

They have  helical thickening of lignin in their walls to prevent collapse

Explanation:

the primary function of Xylem and its conducting vessels tracheids is to provide  support and tranport  water and  minerals  in plants.

Xylem vessels  have layers of dead materials in the walls called LIGNIN.   Lignin is a polymer; a  very strong, hard materials that stop water passage  through it,because it contains dead cells,

Therefore  the presence of  deposit of these strong  impermeable, ligified  walls  in its  walls  prevent its collapse during mass flow of water of transpiration pull.

A daughter cell that matures to the inside of the vascular cambium becomes ______, and a daughter cell that matures to the outsi
melomori [17]

A daughter cell that matures to the inside of the vascular cambium becomes<u> secondary xylem</u> and a daughter cell that matures to the outside of the vascular cambium becomes <u>secondary phloem.</u>

<u />

  • The cambium divides its cells to create secondary xylem and phloem. As secondary phloem and xylem tissue builds up, the stem becomes thicker and develops wood and bark.
  • The kind of xylem produced by secondary growth is known as secondary xylem. In contrast, during primary growth, the primary xylem develops.
  • As a result, lateral growth, as opposed to vertical growth, is connected with the secondary xylem, as opposed to the primary xylem.
  • The procambium, which is found between the xylem axis and the phloem pole, develops into the cambium in the root.
  • A pattern resembling the arrangement of secondary stem is produced when xylem forms in the core and phloem on the perimeter of secondary development.
