1. Which feature is unique to non-flowering coniferous plants?

  1. They reproduce by producing spores
  2. They produce flowers with net-veined leaves
  3. They produce seeds inside cones instead of flowers
  4. They lack a vascular transport system
Show answer

Answer: C

Conifers are non-flowering vascular plants that bear seeds inside specialized structures called cones.

2. Which plant group reproduces by producing spores and lacks a vascular system?

  1. Ferns
  2. Mosses
  3. Conifers
  4. Dicotyledons
Show answer

Answer: B

Mosses are non-vascular plants that reproduce via spores. Ferns also use spores but possess a vascular transport system.

3. How does human deforestation directly affect biodiversity?

  1. It increases the overall number of endemic species
  2. It causes habitat destruction, leading to species endangerment
  3. It promotes balanced food chains across ecosystems
  4. It expands natural in-situ conservation areas
Show answer

Answer: B

Deforestation destroys natural ecosystems, causing loss of food and shelter for wildlife and reducing global biodiversity.

4. Which group of animals contains ONLY invertebrates without legs?

  1. Ant, Grasshopper, Butterfly
  2. Spider, Scorpion, Tick
  3. Planaria, Earthworm, Tapeworm
  4. Crab, Prawn, Centipede
Show answer

Answer: C

Planaria, earthworms, and tapeworms are all invertebrates without legs.

5. To which invertebrate group does an earthworm belong?

  1. Invertebrate without legs and with a non-segmented body
  2. Invertebrate with 3 pairs of jointed legs
  3. Invertebrate without legs and with a segmented body
  4. Invertebrate with 4 pairs of jointed legs
Show answer

Answer: C

Earthworms and leeches are legless invertebrates with segmented bodies.

6. Which of the following defines poikilothermic organisms?

  1. Organisms that generate internal body heat through metabolism
  2. Organisms whose body temperature fluctuates with their surroundings
  3. Organisms that maintain a strictly constant internal temperature
  4. Organisms capable of living only in aquatic ecosystems
Show answer

Answer: B

Poikilothermic animals (cold-blooded) cannot regulate their internal body temperature, so it changes based on the surrounding environment.

7. What is an endemic species?

  1. A species introduced from another country
  2. A species that is completely extinct in the wild
  3. A species found naturally only in a specific geographic area
  4. A species that can survive in all global climates
Show answer

Answer: C

Endemic species are native and restricted to a particular geographical region (e.g., the Proboscis Monkey in Borneo).

8. A balsam plant possesses a taproot system and leaves with network venation. How is it classified?

  1. Monocotyledonous plant
  2. Non-vascular spore plant
  3. Dicotyledonous plant
  4. Gymnosperm conifer
Show answer

Answer: C

Dicotyledonous plants feature taproots and netted (network) leaf venation.

9. Which method represents an example of in-situ conservation?

  1. Setting up seed banks for endangered crops
  2. Establishing a national park to protect natural habitats
  3. Breeding animals inside a city zoo
  4. Cultivating wild flowers in a botanical garden
Show answer

Answer: B

In-situ conservation protects species within their natural habitat (e.g., national parks, forest reserves).

10. A student finds an invertebrate with 4 pairs of jointed legs. Which category does this animal belong to?

  1. Insects
  2. Crustaceans
  3. Arachnids
  4. Myriapods
Show answer

Answer: C

Arachnids (such as spiders and scorpions) possess exactly 4 pairs of jointed legs (8 legs).
