what is the role of the cell wall in plant cells?

The cell wall in plant cells is responsible for cell protection, providing structural support, and giving shape to the cell.

Explanation:

The cell wall in plant cells is responsible for cell protection, providing structural support, and giving shape to the cell.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
