Biology Semester 1 Review

Front

Which part of the Cell Cycle takes the longest?

Back

Interphase is the longest phase of the Cell Cycle, where the cell grows and prepares for division.

Front

Describe the plasma membrane.

Back

The plasma membrane is a phospholipid bilayer with protein channels embedded, allowing selective transport of substances.

Front

What is the flow of genetic information in a cell?

Back

The flow of genetic information is DNA -> RNA -> Protein.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, including processes like osmosis and diffusion.

Front

What is osmosis?

Back

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

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move substances across the membrane.

Front

What is endocytosis?

Back

Endocytosis is an active transport process where cells engulf substances to bring them into the cell.

Front

What are biomolecules?

Back

Biomolecules are organic molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the function of DNA?

Back

DNA stores and transmits genetic information that guides the development and functioning of living organisms.
