Hint: The Kingdom Plantae consists of all the plants ranging from terrestrial to aquatic habitats. These are specialized and differentiated organisms that use sunlight to obtain energy. They make up the largest of the biodiversity. They are the primary sources of energy for other organisms.
Complete answer: Plantae kingdom represents all of the plant species found on the Earth. Plants are highly adaptive, specialized, and differentiated organisms. These are multicellular organisms. This means that they are made up of groups of cells each specialized to perform its own specific task. All of the plants have major organs called stems, roots, and leaves. The stem makes the cylindrical part and the roots are underground structures deep in the soil. The leaves are the photosynthetic centers of a plant.
The plants are eukaryotic organisms because the plant cells have a defined nucleus inside their cells. A typical plant cell consists of an outer protective covering called a cell wall. After the cell wall is the semi-permeable membrane called the plasma membrane. The plasma membrane encloses the cytoplasm and the cytoplasm contains the organelles. The plant cell consists of specialized organelles called the chloroplast. These are the houses of the photosynthetic pigment called chlorophyll. The plants utilize the sun’s light energy absorbed by chlorophyll to make their food. As plants are able to make their food on their own they are called autotrophic. So, plants are multicellular, eukaryotic, and autotrophic organisms.
Thus, option C is the correct answer.
Note: Plants are very adaptable creatures. They inhabit the hot deserts and cold water of the oceans. They undergo various modifications to adapt to their surroundings. For example, desert plants develop spines that are modified leaves. Also, they swell their stems to store water.
