Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Most photosynthetic organisms are contained within which two kingdoms?
A
Plantae and Protista
B
Eubacteria and Fungi
C
Animalia and Fungi
D
Animalia and Plantae
Explanation: 

Detailed explanation-1: -Hence, the correct answer is ‘Plantae’.

Detailed explanation-2: -In terms of organisms, photosynthesis occurs in autotrophes that contain the green pigment chlorophyll. This would include the entire plant kingdom, “half” of the Protista (the algae), & “half” the Moneran Kingdom (the blue-green algae). On the multicellular level, photosynthesis occurs in the leaves of plants.

Detailed explanation-3: -Generally, protists are microscopic, unicellular organisms, though some (like seaweed) are large and multicellular. Some protists (such as algae) are photosynthetic and can make their own food, while others are heterotrophic and seek out food sources in their external environment.

Detailed explanation-4: -They live in various habitats including salt and freshwater aquatic environments, wet soil, or on moist rocks. Photosynthetic algae known as phytoplankton are found in both marine and freshwater environments. Most marine phytoplankton are composed of diatoms and dinoflagellates.

Detailed explanation-5: -Kingdom Plantae is comprised of all multicellular plants found on land and water. The members of this kingdom are eukaryotic and photosynthetic.
