5. Match each cell part to its function by recording the letter of the correct Part of Cell.

Semi-permeable membrane made of phospholipids that acts as a barrier between inside and outside of the cell.

CytoplasmThe fluid, cytoskeleton, and organelles inside a cell.

NucleusContains DNA and control's the cell's activity.

Nuclear EnvelopeDouble membrane that surrounds the nucleus and has pores to allow some molecules (like RNA) out of the nucleus.

NucleolusDark, dense area inside nucleus that makes rRNA.

MitochondriaMakes ATP (chemical energy). Folds inside are called cristae. They have their own DNA.

RibosomesMade of rRNA and proteins. This is where proteins are made.

Rough Endoplasmic Reticulum (RER)Protein highway of sorts (transports proteins mad

Explanation:

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
