Question

Multicellular autotrophs are included in the kingdom ____________.

• A. Fungi
• B. Protista
• C. Plantae
• D. Animalia

Answer 1

The correct option is C

Plantae

The correct option is C.

Explanation of the correct option :

1. All multicellular eukaryotic organisms are classified as members of the kingdom Plantae.
2. They are autotrophs because they use solar energy to produce their food.
3. Plants have cellulose as a cell wall material.
4. They may multiply by dividing their cells. Starch and lipids are plants' reserve food.

Explanation of the incorrect options:

Option A:

The general characteristics of Kingdom Fungi are as follows:

1. Fungi are multicellular, non-green plants. They lack chlorophyll.
2. They are heterotrophs in nature because they cannot produce their food.
3. They show the parasitic or saprophytic mode of nutrition.
4. Fungi can be single-celled, multicellular, or filamentous.
5. Fungi are classified into three groups based on their shape: thread-like fungi (such as bread mould), club fungi (such as mushrooms), and sac fungi (yeast).

Option B:

The general characteristics of Kingdom Protista are as follows:

1. Unicellular eukaryotic organisms (with a well-defined nucleus) such as unicellular algae, protozoans, and unicellular fungi fall into this category.
2. Appendages, such as hair-like cilia (e.g., Paramecium) or whip-like flagellum(e.g., Euglena), are used by some of these organisms.
3. They can be autotrophic (e.g., unicellular algae, diatoms) or heterotrophic (e.g., protozoans).
4. Examples are Chlorella, Chlamydomonas, diatoms, and protozoans.

Option D:

The general characteristics of Kingdom Animalia are as follows:

1. Kingdom Animalia includes all animals.
2. The animal kingdom is the most widespread of the five kingdoms.
3. Animals are eukaryotes, which are multicellular organisms.
4. They do not possess chlorophyll or a cell wall, as do plants.
5. They exhibit a heterotrophic mode of nutrition.

Final Answer: Multicellular autotrophs are included in the kingdom Plantae.
