Worksheet on Diversity, Hierarchy and Classification of Kingdom Plantae

Solved Questions on Diversity, Hierarchy, and Classification of Kingdom Plantae

1. A scientist is studying an organism (shown in the picture) with the following characteristics: unicellular structure, eukaryotic cells, autotrophic nutrition, chloroplast and the presence of flagella for movement. Identify the organism and the kingdom it most likely belongs to.

a) Cyanobacteria: Monera
b) Euglena: Protista
c)Lichen: Fungi
d) Sea Lettice: Plantae

Answer: b) The organism in the picture with the given characteristics (unicellular structure, eukaryotic cells, autotrophic nutrition, chloroplast, and the presence of flagella for movement) is most likely Euglena which belongs to the kingdom Protista.

2. Classify the following plants into Gymnosperms and Angiosperms:

a) Gymnosperms: I, III; Angiosperms: II, IV, V
b) Gymnosperms: II, V; Angiosperms: I, III, IV
c) Gymnosperms: I, III, V; Angiosperms: II, IV
d) Gymnosperms: III; Angiosperms: I, II, IV, V

Answer: c) Gymnosperms: I, III, V; Angiosperms: II, IV
Gymnosperms: Pine tree, Cycad, Spruce tree
Angiosperms: II, IV: Maple tree, Sunflower

3. An expedition to a remote rainforest uncovers a new species of orchid with distinct floral characteristics. The scientists on the expedition are excited to document their discovery, including giving the orchid a scientific name. How does binomial nomenclature help them accurately classify and communicate about the orchid's features?

a) It allows them to choose a name based on the orchid's location in the rainforest.
b) It provides a standardised system for naming the orchid, ensuring clarity among scientists.
c) It enables them to assign a name that reflects the orchid's market value.
d) It eliminates the need to use scientific names in research publications.

Answer: b) Binomial nomenclature provides a systematic and consistent approach to naming organisms. By assigning a unique scientific name using the binomial format (genus species), scientists ensure that there is a standardised way to refer to the newly discovered orchid. This helps prevent confusion caused by common names that may vary between languages or regions.

4. On a field trip, students collected samples of various organisms from a pond ecosystem. They found algae, mosses, and ferns among the collected samples. What is the classification of these organisms based on your knowledge of plant diversity?

a) All are angiosperms
b) All are gymnosperms
c) Algae are pteridophytes, mosses are angiosperms, and ferns are bryophytes
d) Algae are thallophytes, mosses are pteridophytes, and ferns are pteridophytes

Answer: d) Algae are thallophytes, mosses are pteridophytes, and ferns are pteridophytes

5. Complete the following flowchart by accurately identifying A, B, C and D.

a) A: Prokaryotes, B: Unicellular, C: Animalia, D: Fungi
b) A: Bacteria, B: Unicellular, C: Alage, D: Fungi
c) A: Prokaryotes, B: Bacteria, C: Fungi, D: Monera
d) A: Prokaryotes, B: Monera, C: Protista, D: Monera

Answer: a) A: Prokaryotes, B: Unicellular, C: Animalia, D: Fungi

FAQs

1. What are the types of plant kingdom?

Plants in the Kingdom Plantae are divided into many major groupings based on their traits and evolutionary histories. These groupings include bryophytes (mosses and liverworts), ferns and their associates (ferns, horsetails, and club mosses), gymnosperms (conifers and cycads), and angiosperms (flowering plants).

2. What Are the Characteristics of Bryophytes?

Bryophytes, such as mosses and liverworts, are non-vascular plants that lack real roots, stalks, and leaves. They reproduce by spores and often develop in damp conditions, contributing significantly to soil formation and ecological succession.

3. What Are Gymnosperms and How Are They Adapted to Their Environments?

Gymnosperms are plants that produce seeds, such as conifers, cycads, and ginkgoes. They feature seeds that are not encapsulated within fruits and leaves that resemble needles or scales. Gymnosperms are adaptable to a wide range of habitats, including temperate woods, deserts, and alpine areas.

4. What Are Some Examples of Economically Important Plants in Kingdom Plantae?

Many plants in the Kingdom Plantae are economically significant and utilized for food, medicine, fibre, lumber, fuel, and ornamentation. Examples include grain crops (wheat, rice, maize), medicinal herbs (ginseng, echinacea), timber trees (oak, pine), and decorative flowers (roses, orchids).

5. What are some examples of plant kingdom?

Here are some examples of plants from different groups within the plant kingdom

1. Bryophytes:

   1. Mosses (e.g., Sphagnum moss, Polytrichum moss)
   2. Liverworts (e.g., Marchantia, Riccia)
   3. Hornworts (e.g., Anthoceros)

2. Pteridophytes:

   1. Ferns (e.g., Boston fern, Maidenhair fern)
   2. Horsetails (e.g., Equisetum)
   3. Club mosses (e.g., Lycopodium, Selaginella)

3. Gymnosperms:

   1. Conifers (e.g., Pine trees, Spruce trees, Fir trees)
   2. Cycads (e.g., Cycas)
   3. Ginkgoes (e.g., Ginkgo biloba)
   4. Gnetophytes (e.g., Ephedra, Welwitschia)

4. Angiosperms:

   1. Grasses (e.g., Wheat, Rice, Maize)
   2. Shrubs (e.g., Rose bushes, Azaleas)
