SECTION C: SHORT ANSWER QUESTIONS

Prokaryotic cells lack a nucleus and membrane-bound organelles (e.g., Bacteria). Eukaryotic cells have a true nucleus and organelles (e.g., Amoeba, human cells).
Autotrophic nutrition is making one's own food, usually via photosynthesis (e.g., plants). Heterotrophic nutrition is obtaining food by consuming other organisms (e.g., animals).
Kingdom Monera: Unicellular prokaryotes, cell walls of peptidoglycan, diverse metabolism.
Kingdom Protista: Unicellular eukaryotes, diverse forms, includes autotrophs and heterotrophs.
Kingdom Fungi: Multicellular eukaryotes (except yeast), chitin cell walls, heterotrophic (saprophytic/parasitic).
Kingdom Plantae: Multicellular eukaryotes, cellulose cell walls, autotrophic (photosynthesis).
Kingdom Animalia: Multicellular eukaryotes, no cell walls, heterotrophic, motile.
Fungi cell walls are made of chitin. Plantae cell walls are made of cellulose.
Thallophyta (algae) have simple, undifferentiated bodies. Bryophyta (mosses) have simple stems and leaves but no true roots.
Pteridophyta (ferns) are non-flowering, seedless vascular plants. Spermatophyta are seed-bearing vascular plants.
Chordates have a notochord at some stage of life. Non-chordates lack a notochord.
Porifera (sponges) have a cellular level of organization and are asymmetrical. Coelenterata (jellyfish) have tissue-level organization and radial symmetry.
Platyhelminthes (flatworms) are acoelomate and have a flattened body. Nematoda (roundworms) are pseudocoelomate and have a cylindrical body.
Annelida (earthworms) have a segmented body. Arthropoda (insects) have jointed appendages and an exoskeleton.
Mollusca (snails) have a soft body, often with a hard shell. Echinodermata (starfish) have a spiny skin and a water vascular system.
Pisces (fish) are aquatic, gill-breathing vertebrates. Amphibia (frogs) live on land and in water, and have lungs in the adult stage.
Reptilia (lizards) are cold-blooded, have scales, and lay eggs on land. Aves (birds) are warm-blooded, have feathers, and can fly.
Aves (birds) have feathers and lay eggs. Mammalia (humans) have hair/fur and give birth to live young.
Saprophytic nutrition is obtaining nutrients from dead and decaying organic matter. Examples include mushrooms and bread mold.
Binary fission is a form of asexual reproduction where a parent cell divides into two identical daughter cells. It is common in bacteria.
Pseudopodia in Amoeba are used for locomotion (crawling) and for engulfing food particles (phagocytosis).
Contractile vacuoles are organelles in many protists that pump excess water out of the cell to maintain osmotic balance.
Cilia and flagella are whip-like appendages used for locomotion in many protists and some animal cells.
Spore formation in fungi is a common method of asexual reproduction where specialized cells (spores) are produced and dispersed to grow into new individuals.
Alternation of generations in plants is a life cycle that alternates between a multicellular diploid (sporophyte) stage and a multicellular haploid (gametophyte) stage.
Mycorrhizal associations are symbiotic relationships between fungi and plant roots. The fungus helps the plant absorb nutrients, and the plant provides the fungus with carbohydrates.
Lichens are composite organisms arising from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.
Chemosynthesis is the process by which some organisms, such as certain bacteria, use energy derived from reactions involving inorganic chemicals to produce food.
Bioluminescence is the production and emission of light by a living organism. It is seen in some fungi, bacteria, and marine animals like jellyfish.
The endosymbiotic theory proposes that eukaryotic organelles like mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by another cell.
Archaebacteria are a group of microorganisms considered to be an ancient form of life that can live in extreme environments like hot springs and salt lakes.
Plasmids are small, circular, double-stranded DNA molecules that are distinct from a cell's chromosomal DNA. They are common in bacteria and can carry genes for antibiotic resistance.
Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis.
Food vacuoles are organelles found in protists that contain and digest food particles engulfed by the cell.
Conjugation is a process of genetic transfer in bacteria where one bacterium transfers genetic material to another through direct contact.
Polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative phenotypes, in the population of a species. It is seen in cnidarians (e.g., polyp and medusa forms).
Regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts. It is highly developed in lower animals like starfish and flatworms.

SECTION D: BROAD ANSWER QUESTIONS

The Five Kingdom Classification, proposed by R.H. Whittaker, divides all living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. The basis for this classification includes cell structure (prokaryotic vs. eukaryotic), body organization (unicellular vs. multicellular), and mode of nutrition (autotrophic vs. heterotrophic).
- Monera: Unicellular prokaryotes.
- Protista: Unicellular eukaryotes.
- Fungi: Multicellular, heterotrophic eukaryotes with chitin cell walls.
- Plantae: Multicellular, autotrophic eukaryotes with cellulose cell walls.
- Animalia: Multicellular, heterotrophic eukaryotes with no cell walls.
Kingdom Monera consists of unicellular prokaryotic organisms like bacteria and cyanobacteria. They lack a true nucleus and membrane-bound organelles. Their cell wall is made of peptidoglycan. Nutrition is diverse, including autotrophic (photosynthesis, chemosynthesis) and heterotrophic (saprophytic, parasitic) modes. Reproduction is primarily asexual, through binary fission. They are ecologically important as decomposers, nitrogen-fixers, and pathogens.
Kingdom Protista includes unicellular eukaryotic organisms like Amoeba and Paramecium. They exhibit a wide diversity of forms and life cycles. Their nutrition can be autotrophic (e.g., algae), heterotrophic (e.g., protozoans), or both. Reproduction can be asexual (binary fission) or sexual. Protists are evolutionarily significant as they are believed to be the ancestors of multicellular eukaryotes.
Kingdom Fungi comprises multicellular (except for yeast) eukaryotic organisms like mushrooms and molds. They have cell walls made of chitin and are heterotrophic, obtaining nutrients by absorption (saprophytic or parasitic). They reproduce through spores, both sexually and asexually. Fungi are economically important as a source of food (mushrooms), antibiotics (penicillin), and in fermentation (yeast). Ecologically, they are crucial as decomposers.
Kingdom Plantae includes multicellular, eukaryotic, and autotrophic organisms. Their cell walls are made of cellulose, and they contain chloroplasts for photosynthesis. The kingdom is divided into Thallophyta (algae), Bryophyta (mosses), Pteridophyta (ferns), and Spermatophyta (seed plants). This shows an evolutionary trend from simple, aquatic forms to complex, terrestrial forms with vascular tissues and seeds. Plants are the primary producers in most ecosystems.
Kingdom Animalia consists of multicellular, eukaryotic, and heterotrophic organisms that lack cell walls. They are classified into numerous phyla, from simple sponges (Porifera) to complex chordates (Chordata). Key evolutionary trends include the development of tissues, organs, bilateral symmetry, a coelom, and a nervous system. The diversity of forms is vast, ranging from insects to mammals.
Comparison of the Five Kingdoms:
- Cellular Organization: Monera are prokaryotic; the other four are eukaryotic.
- Body Organization: Monera and Protista are unicellular; Fungi, Plantae, and Animalia are multicellular.
- Nutrition: Plantae are autotrophic. Fungi and Animalia are heterotrophic. Monera and Protista include both autotrophs and heterotrophs.
- Reproduction: Asexual reproduction is common in all kingdoms. Sexual reproduction is present in all except some Monera.
- Ecological Roles: Plantae are producers. Fungi are decomposers. Animalia are consumers. Monera and Protista have diverse roles.
The evolutionary sequence is generally considered to be from Monera -> Protista -> Fungi, Plantae, and Animalia. Key milestones include the evolution of the eukaryotic cell (endosymbiosis), multicellularity, and specialized tissues and organs. This progression led to the vast diversity of life we see today.
Economic Importance:
- Monera: Beneficial (nitrogen fixation, gut bacteria), harmful (diseases).
- Protista: Beneficial (plankton as food source), harmful (malaria, red tides).

- Animalia: Beneficial (food, labor, pollination), harmful (pests, disease vectors).
Ecological Roles:
- Producers: Plantae, some Protista, and some Monera form the base of food chains.
- Consumers: Animalia and some Protista.
