Which processes occur in a plant embryo before it pushes out of the soil? check all that apply.
a. it uses food from the seed.
b. its leaves open.
c. it produces its own food.
d. its roots grow downward.
e. its stem grows upward.

A, C and D

Explanation:

A plant embryo must have some strength before it pushes out of the soil.

It will first feed from the nutrients the seed has. Then it will start to grow up its roots downward in order to have the way to absorve energy from the soil. Once it is acquiring this energy from the soil, it will start growing the stem upward, opening up the space to push out of the soil.

After it has pushed out of the soil, the opening of the leaves and production of its own energy in the photosynthesis will take place.

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
