Write an argumentative essay which says without photosynthesis there is no life

AysviL [449]

Explanation:

you could include the points such as,

--> photosynthesis produces O2 which is necessary for respiration.

-->photosynthesis reduces the amount of CO2 in the atmosphere as it uses it up in the reaction. this controls the atmospheric rate of CO2 and reduced the greenhouse effect.

--> plants are the primary producers in a food chain and so, photosynthesis plays a primary role in the stability of food chains as they're the primary source of glucose as all the higher consumption is based off the producer.

--> virtually seeing, all the energy within the biosphere is based off plants that depends on photosynthesis.

--> If photosynthesis ceased, there would soon be little food or other organic matter on Earth, most organisms would disappear, and Earth's atmosphere would eventually become nearly devoid of gaseous oxygen.

there could be more but this is all I could think of.

hope it helps. :)

Why are so many starch grains found in the cortex?

rosijanka [135]

There are many grains of starch in the cortex because it represents the reserve food material of plants.

This source of food material is consumed during plant metabolism, as food when plants are under stress, or as an energy source in seed germination and early seedling stages.

The cortex, in plants, is a vascular tissue responsible for the transport of food (processed sap) from the leaves to the rest of the plant .

Starch grains are the most common solid particles that plant cells develop within plastids.

Assimilation starch is a temporary product of photosynthesis and is formed in chloroplasts, while reserve starch is formed in amyloplasts, which are contained in parenchymal cells of the cortex, in vascular tissues of stems and roots, in the pith of stems, in fruits, leaves, fleshy cotyledons and in modified stems, such as tubers and rhizomes.

Starch is the main energy and carbon reserve in plants, supplying the energy and carbon skeletons necessary for the plant's metabolism during periods of darkness, when photosynthesis is inactive.

Therefore, we can conclude that starch grains (ergasstic substances) are found in abundance in the cortex because it represents a reserve of essential molecules for the functioning and maintenance of the cellular structure.

When the ball reaches maximum height, its kinetic energy is at a. nextreset?

Anton [14]

Please fix your question, and this belongs in science, not biology. When the ball hits it's maximum height, it's kinetic energy will change to zero, and it will be converted to potential energy.

State disadvantage of self pollination

Oxana [17]

Answer:

A very few pollen grain can pollinate the flower. Purity of the race is maintained. Self-pollination avoid wastage of pollen grains. Less chances of failure of pollination.

The retreat of the shallow seas of the Paleozoic left much of Virginia exposed during the Permian and Mesozoic. In central Virgi

Kisachek [45]

The given blank can be filled with dinosaur footprints.

In the Precambrian, the sedimentary rocks deposition took place in the Blue Ridge Province of Virginia, however, no fossils have been positively determined from these deposits. The Paleozoic rocks are well documented in Virginia. The occurrences of shallow area deposition were obstructed by subsequent periods of erosion and mountain-building incidents.

The withdrawal of the widespread shallow regions of the Paleozoic left much of the state exposed at the time of Mesozoic and Permian. In central Virginia, fossils of freshwater fish, dinosaur footprints, and insects are found in the rift basin deposits of the Triassic.
