Question 7(Multiple Choice Worth 2 points) (06.02 HC)

Euglena and several other protists that use their cilia or flagella to move around and gather food are classified along with the plant-like protists. What is the most logical conclusion that can be drawn from this grouping?

They are parasitic on plants and use the plant chloroplasts to photosynthesize.
They must also be able to gather energy through photosynthesis.
Their ancestors were plants that lost their multicellular characteristics.
There must be a point in their life cycle when they produce leaves.

They must also be able to gather energy through photosynthesis.

Explanation:

Some algae are considered protists and have photosynthetic pigments in the body, such as certain species of Chlorela, Chlorogonium, Euglena and Navicula are able to grow normally in the dark or in a carbon-deficient environment provided they are supplied with substances. high energy and easily metabolizable chemicals such as fatty acids, acetates, carbohydrates, etc.

For this reason, we can say that Euglena and several other protists, as well as plants, must also be able to collect energy through photosynthesis.

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."
