Dependent Variable

The variable that is measured or observed in response to changes in the independent variable.

Fixed/Controlled Variable

Variables that are kept constant throughout an experiment to ensure valid results.

Quantitative Data

Data that can be measured and expressed numerically, focusing on quantities.

Qualitative Data

Plant Cell

A eukaryotic cell that contains a cell wall, chloroplasts, and a large central vacuole.

Animal Cell

A eukaryotic cell lacking a cell wall and chloroplasts, and typically smaller than plant cells.

Differences between Plant and Animal Cells

Plant cells have a cell wall and chloroplasts; animal cells have lysosomes and centrioles.

Microscope

An instrument that magnifies small objects to view details not visible to the naked eye.

Flow Diagram of Biological Organization

A visual representation illustrating the hierarchical structure of life, from cells to ecosystems.

Mitosis

A process of cell division that results in two identical daughter cells, essential for growth and repair.

Meiosis

A type of cell division that reduces the chromosome number by half, producing haploid gametes.

Definition of Cancer

A group of diseases characterized by uncontrolled cell division and growth.

Types of Cancer

Different forms of cancer categorized by the cells they originate from, such as carcinoma, sarcoma, etc.

Treatment of Cancer

Methods used to treat cancer including surgery, chemotherapy, radiation therapy, and immunotherapy.

Functions of the Skeleton

The skeleton provides structure, protects organs, anchors muscles, and stores calcium.
