Q1. Which kingdom consists primarily of single-celled organisms that lack a true nucleus and are known for their diverse metabolic capabilities?
a) Animalia
b) Plantae
c) Protista
d) Fungi
Show Answer
Correct Answer: c) Protista
Explanation: Protista is a diverse kingdom consisting of eukaryotic organisms that do not fit into the other kingdoms. They include protozoans, algae, and slime molds. Protists exhibit various metabolic modes, including photosynthesis, ingestion, and absorption.
Q2. Organisms in which kingdom are characterized by their ability to produce their own food through photosynthesis and are typically multicellular with cell walls composed of cellulose?
a) Protista
b) Plantae
c) Animalia
d) Fungi
Show Answer
Correct Answer: b) Plantae
Explanation: The kingdom Plantae consists of multicellular, photosynthetic organisms known as plants. They have specialized structures for photosynthesis, such as chloroplasts, and possess cell walls composed of cellulose. Plants play a crucial role in ecosystems by producing oxygen and serving as primary producers.
Q3. Which kingdom includes multicellular, eukaryotic organisms that obtain nutrients through absorption and are often found decomposing organic matter in their environment?
a) Protista
b) Plantae
c) Animalia
d) Fungi
Show Answer
Correct Answer: d) Fungi
Explanation: Fungi are heterotrophic organisms that obtain nutrients by secreting enzymes to break down organic matter, which they then absorb. They play essential roles in nutrient cycling and decomposition in ecosystems. Fungi include molds, yeasts, and mushrooms.
Q4. Organisms in which kingdom are characterized by their ability to ingest food and typically possess specialized sensory organs and nervous systems for locomotion and coordination?
a) Protista
b) Plantae
c) Animalia
d) Fungi
Show Answer
Correct Answer: c) Animalia
Explanation: The kingdom Animalia consists of multicellular, heterotrophic organisms capable of ingesting food. Animals exhibit diverse forms and lifestyles, ranging from microscopic worms to large mammals. They possess specialized sensory organs, nervous systems, and locomotor structures for feeding, movement, and response to stimuli.
Q5. Which kingdom includes organisms that are primarily unicellular, prokaryotic, and exhibit diverse metabolic capabilities, including photosynthesis, nitrogen fixation, and fermentation?
a) Protista
b) Plantae
c) Animalia
d) Monera
Show Answer
Correct Answer: d) Monera
Explanation: The kingdom Monera comprises unicellular organisms, including bacteria and cyanobacteria (blue-green algae). These organisms lack a true nucleus and organelles and exhibit various metabolic capabilities crucial for nutrient cycling and ecological processes.
Q6. In the Five Kingdom classification system, which kingdom encompasses organisms that possess a true nucleus and are primarily multicellular, heterotrophic, and motile?
a) Monera
b) Protista
c) Fungi
d) Animalia
Show Answer
Correct Answer: d) Animalia
Explanation: The kingdom Animalia consists of multicellular, eukaryotic organisms that possess true nuclei and are heterotrophic, meaning they obtain nutrients by ingesting food. Animals exhibit diverse forms and lifestyles, ranging from microscopic organisms to large vertebrates.
Q7. Which kingdom includes organisms that can be either unicellular or multicellular, possess a true nucleus, and exhibit diverse metabolic capabilities, including photosynthesis, ingestion, and absorption?
a) Animalia
b) Plantae
c) Protista
d) Fungi
Show Answer
Correct Answer: c) Protista
Explanation: Protista is a diverse kingdom comprising eukaryotic organisms that do not fit into the other kingdoms. Protists can be unicellular or multicellular and exhibit various metabolic modes, including photosynthesis, ingestion, and absorption.
Q8. Organisms in which kingdom are characterized by their ability to synthesize their own food through photosynthesis, possess chloroplasts, and often have cell walls made of cellulose?
a) Animalia
b) Plantae
c) Protista
d) Fungi
Show Answer
Correct Answer: b) Plantae
Explanation: The kingdom Plantae consists of multicellular, photosynthetic organisms known as plants. They possess chloroplasts, which contain chlorophyll for photosynthesis, and have cell walls made of cellulose. Plants are primary producers in most ecosystems.
Q9. Which kingdom includes organisms that obtain nutrients through absorption, possess cell walls made of chitin, and play crucial roles in nutrient recycling and decomposition in ecosystems?
a) Plantae
b) Animalia
c) Fungi
d) Protista
Show Answer
Correct Answer: c) Fungi
Explanation: Fungi are heterotrophic organisms that obtain nutrients through absorption. They possess cell walls made of chitin and play essential roles in decomposing organic matter, nutrient cycling, and symbiotic relationships in ecosystems.
Q10. In the Five Kingdom classification system, which kingdom encompasses organisms that are primarily unicellular, prokaryotic, and exhibit diverse metabolic capabilities such as nitrogen fixation and fermentation?
a) Animalia
b) Plantae
c) Fungi
d) Monera
Show Answer
Correct Answer: d) Monera
Explanation: The kingdom Monera includes unicellular, prokaryotic organisms such as bacteria and cyanobacteria (blue-green algae). These organisms exhibit diverse metabolic capabilities crucial for nutrient cycling, nitrogen fixation, and other ecological processes.
