Plant cells are miniature factories that make thousands of chemical compounds for themselves and the whole world. True False

True

Explanation:

Plants are a diverse group of the organism which are characterised by their green colour because of the photosynthetic pigments called chlorophyll. The plants are one of the important factors which have maintained the evolution of the animal species including humans.

The heterotrophic organism which cannot make organic and inorganic compounds on their own for survival obtain them from plants.

The chemical composition of the plants shows that they make a variety of chemicals which prove useful to humans like oil, coumarin, capsaicin, gums, rubber, gums, the starch in the form of potato, and many others. These natural products extracted from the plants are very useful to humans.

Thus, true is the correct answer.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
