Which of the following is a correct statement about sugar movement in phloem?

sugar transport does not require energy.
sugar is translocated from sinks to sources.
movement can occur both upward and downward in the plant.
diffusion can account for the observed rates of transport.
only xylem cells can perform sugar movement

The correct answer is: Movement can occur both upward and downward in the plant.

Phloem is a plant tissue (in vascular plants) that transports the organic compounds made during photosynthesis in the form of sap-water based solution rich in sugars. Phloem is composed of living cells  generally called sieve elements. Transport of sap is multidirectional: sometimes sugars made in photosynthesis are transported to non-photosynthetic parts of the plant, such as the roots but sometimes roots are sugar sources so the sap needs to be transported upward for the plant’s growth.

1.the evidene of the reaction

2.yes

3.yes

yes its like the dead sea which is full of salt which makes you stay afloat

so yes an egg will float in salt
