Rajac Language School Science Practical Models Flashcards

A set of vocabulary flashcards covering cell division, lever mechanics, floral sex classification, types of inflorescence, and the fertilization process based on Grade 8 science practical models.

Mitosis

A type of cell division where a $2n$ cell divides into two identical $2n$ cells.

Meiosis

A type of cell division process characterized in the provided practical models as Figure (2).

Levers that save effort

Levers where the effort arm is longer than the load arm and the mechanical advantage is greater than $1$.

Levers that do not save effort

Levers where the effort arm is shorter than the load arm and the mechanical advantage is less than $1$.

Male flower

The sex of a flower represented by figure 1 in the practical model.

Female flower

The sex of a flower represented by figure 2 in the practical model.

Bisexual flower

The sex of a flower represented by figure 3 in the practical model.

Simple raceme inflorescence

A type of inflorescence found in plants such as the Snapdragon plant and stock plant.

Simple corymb inflorescence

A type of inflorescence found in plants such as the Cherry plant and Iberis plant.

Simple umbellate inflorescence

A type of inflorescence found in plants such as the Garlic plant and onion plant.

Sperm
