Alexxandr [17]

Answer:

All living things are made up of one or more cells.

Explanation:

The cell theory is a universal theory proposed by three scientists viz: Theodor Schwann, Mathias Scleiden, and Rudolf Virchow in the year 1838. These three scientists contributed to the cell theory and proposed the following:

1) All living things are composed of one or more cells

2) Cell is the basic and fundamental unit of life

3) New cells arise from pre-existing cells.

However, at an earlier date specifically 1665, an English scientist named Robert Hooke has discovered and coined the term "cells" in his published book by observing a piece of cork under a microscope. This Hooke's discovery of cells from a once living cork best supports the part of the cell theory that states that: All living things are made up of one or more cells.

In C3 plants the conservation of water promotes_______.a. photorespiration. b. a shift to C4.c. photosynthesis.d. the opening of
ankoles [38]

Answer:

A) photorespiration.

Explanation:

Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.

The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate. The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.

The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.

Thus, Option-A is correct.
