1. Binomial Nomenclature Rules

Key Concepts & Definitions

  • Rules of binomial nomenclature: A standardized system for naming species, established by LINNAEUS (1753), which states that each species is given a two-part Latin name, with the genus name first and the species name second.
  • Genus and species naming conventions: The genus name must start with a capital letter, while the species name begins with a lowercase letter; both names are written in Latin or Latinized form.
  • Italicizing or underlining scientific names: When handwritten, scientific names should be underlined separately; when typed, they should be italicized to distinguish them from common names, ensuring clarity and consistency in scientific communication.

2. Osmosis in Potato Cylinders

Key Concepts & Definitions

  • Osmosis process in plant cells: The movement of water molecules from a region of higher water potential to a region of lower water potential across a semi-permeable membrane, without the expenditure of energy, as observed in plant tissues like potato cells.

Binomial Nomenclature — rules?

Genus capitalized, species lowercase, italicized or underlined.

Osmosis — in potato cylinders?

Water moves across membranes, affected by sucrose concentration.

Photosynthesis site — in chloroplast?

Light-independent stage occurs in the stroma.

Leaf adaptations — for photosynthesis?

Large surface area, thin cuticle.

Bile — role?

Emulsifies fats for digestion.

HCl — role?

Activates enzymes, kills microbes.
