3 Domains

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the main difference between gram-positive and gram-negative bacteria?

Back

Gram-positive bacteria have a thick peptidoglycan layer in their cell wall, which retains the crystal violet stain used in the Gram staining procedure, making them appear purple. Gram-negative bacteria have a thinner peptidoglycan layer and an outer membrane, which does not retain the stain, making them appear red.

Front

Which domain do bacteria belong to?

Back

Bacteria belong to the domain Bacteria, which is distinct from the domains Archaea and Eukarya.

Front

What is a defining feature of the Excavata group?

Back

Members of the Excavata group are characterized by their feeding groove, which is a unique structure used for feeding.

Front

What is pseudopodia?

Back

Pseudopodia are temporary projections of eukaryotic cells, used for movement and feeding, commonly found in organisms like amoebas.

Front

What are the three domains of life?

Back

The three domains of life are Bacteria, Archaea, and Eukarya.

Front

What is primary endosymbiosis?

Back

Primary endosymbiosis is the process by which a eukaryotic cell engulfs a prokaryotic cell, leading to the formation of organelles like chloroplasts and mitochondria.

Front

What is secondary endosymbiosis?

Back

Secondary endosymbiosis occurs when a eukaryotic cell engulfs another eukaryotic cell that has already undergone primary endosymbiosis.

Front

What is the role of flagella in protists?

Back

Flagella are whip-like structures that enable protists to move through their environment, aiding in locomotion.

Front

What are Rhizarians known for?

Back

Rhizarians are known for their ability to move by pseudopodia and often have intricate shell structures.
