Achromoplast stores while a leucoplast stores A. starch; pigments B. chlorophyll; starch C. pigments; chlorophyll D. pigments; starch​

Answers

Answer:

D. pigments; starch.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.

A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.

On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.

Hence, a chromoplast stores pigments while a leucoplast stores starch.

Answers

Answer:

direct surface temperature measurements. changes in rainfall and weather patterns. an increase in the frequency of extreme weather events.

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth's climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks.

Strongest Evidence:

Scientists say the accumulation of heat in the oceans is the strongest evidence of how fast Earth is warming due to heat-trapping gases released by the burning of fossil fuels.
