Which statement describes the role of phloem within a plant? a) it transports food to all the parts of the plant both upwards and downwards. b) it transports water to all the parts of the plant only in the upward direction. c) it transports food to all the parts of the plant only in the downward direction. d) it transports water to all the parts of the plant both in the upward and downward direction.

It transports food to all the parts of the plant both upwards and downwards is the correct answer.

Explanation:

Phloem is tissue present in plants that transport the food prepare in the leaves to other parts of the plant.

Phloem has various types of specialized cells such as parenchyma cells, sieve elements, sclerenchyma, and companion cells.

Phloem transfers the food from source(leaves)to sink(to the other parts of the plant's cells), and in the spring process get reversed as the food stored in the sink move towards the developing buds through the phloem that's the reason phloem transports food to all the parts of the plant both upwards and downwards and movement of food is bidirectional.

chordata is the answer

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
