All eukaryotic cells have a cytoskeleton, including plant cells, which have cell walls as well. What does the cytoskeleton in a plant cell do that the cell wall cannot? Question 16 options:

a. It acts as a framework inside the endoplasmic reticulum and keeps it from collapsing.

b. It provides energy and helps to move molecules throughout the cell.

c. It helps keep the organelles in place and directs their movement as needed.

d. It keeps the DNA safely enclosed in the nucleus and holds the nucleus together.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
