What are the five kingdoms proposed by R.H. Whittaker in his classification system?

Monera, Protista, Fungi, Plantae, and Animalia

Bacteria are classified into two main categories based on their cell structure: Gram-positive and ___ bacteria.

Gram-negative

True or False: Mycoplasma bacteria possess a cell wall.

False. Mycoplasma lack a cell wall, making them unique among bacteria.

What are the three methods of genetic material exchange in bacteria?

The three methods are transformation, conjugation, and transduction.

The group of unicellular eukaryotes that includes diatoms and desmids is known as ___.

Chrysophytes

True or False: Euglenoids possess a rigid cell wall.

False. Euglenoids lack a cell wall and have a flexible pellicle instead.

What is the primary characteristic of amoeboid protozoans, and how do they utilize this feature?

Amoeboid protozoans are characterized by the presence of pseudopodia, which they use for movement and capturing prey.

True or False: The flagellated protozoans primarily use cilia for movement and food intake.

False. Flagellated protozoans are characterized by the presence of flagella, not cilia, for movement.

Fungi are primarily ___ in their mode of nutrition.

Heterotrophic, obtaining nutrients through absorption

True or False: The main food reserve in fungi is starch.

False. The main food reserve in fungi is glycogen.

What is the significance of dikaryon cells in the life cycle of basidiomycetes and ascomycetes?

Dikaryon cells (n+n) have two nuclei per cell and result from plasmogamy not being immediately followed by karyogamy, allowing for complex life cycles and genetic diversity.

Kingdom Plantae is primarily characterized by the presence of ___ and ___ in their cellular structure.

Chlorophyll and rigid cell walls made of cellulose

True or False: All organisms in Kingdom Animalia are autotrophic.

False. All organisms in Kingdom Animalia are heterotrophic.

Organisms in the Kingdom Plantae can be classified into two main categories: ___ and ___.

Flowering plants and Non-Flowering plants
