Front

What are lipids?

Back

Lipids are organic molecules that are insoluble in water and include fats, oils, and waxes. They serve as energy storage, structural components of cell membranes, and signaling molecules.

What is the function of a selectively permeable membrane?

Back

A selectively permeable membrane regulates what enters and leaves the cell, allowing certain substances to pass while blocking others.

Front

How many daughter cells are produced in mitosis?

Back

Mitosis produces 2 daughter cells that are genetically identical to the parent cell.

Front

What is endocytosis?

Back

Endocytosis is a type of molecular transport where cells engulf external substances, bringing them into the cell.

Front

What abiotic factor limits plant growth at high altitudes?

Back

The temperature of the area limits the altitude at which plants can grow, as extreme cold can inhibit growth.

Front

What are the four main types of organic molecules?

Back

The four main types of organic molecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the primary function of carbohydrates?

Back

Carbohydrates serve as a primary source of energy for living organisms and are also involved in structural functions.

Front

What is the role of proteins in the cell?

Back

Proteins perform a variety of functions including catalyzing biochemical reactions (enzymes), providing structural support, and facilitating communication between cells.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.
