<span>Carbon enters the atmosphere as carbon dioxide from respiration (breathing) and combustion (burning). This then reacts in the atmosphere in the carbon dioxide cycle, increasing global warming as gases get trapped by the ozone layer. Autotrophs use energy from the sun and inhale CO2 to release oxygen through photosynthesis. Heterotrophs respire and are consumers of plant life, through cellular respiration, waste products are created, organism decay, dead organisms and their waste products then transform into fossils and fossil fuels used for energy resources and feed into the ocean uptake. The entire cycle creates a greenhouse effect on the planet and carbon and nitrogen gases become trapped in the atmosphere.

Animal, Plant and Root Respiration + Auto and Factory Emissions
=> CO2 cycle + sunlight => photosynthesis
=> organism decay, dead organisms + waste products
=> fossils and fossil fuels + ocean uptake
Answer:
Gymnosperms and lower vascular plants have sieve cells as their sieve elements, while sieve tubes are characteristic of flowering plants angiosperms. In gymnosperms, typical companion cells are lacking in the phloem. In gymnosperms, generally the xylem contains only tracheids. Vessels are absent.

Answer:
Grana and stroma
Explanation:
Photosynthesis is the process by which plants make their organic food. This process occurs in the chloroplast of the cell. Grana and stroma are the two parts that are involved in photosynthesis.
Grana are stacks of thylakoid which increase the surface area for light absorption. It is the place where light-dependent reaction occurs. Stroma is the fluid that surrounds grana. It contains the enzyme which is required in photosynthesis. It is the place where light independent reaction occurs.
Stroma is the place where synthesis of organic material from carbon dioxide and water occurs. Therefore the correct answer is grana and stroma.
