2024 Biology Semester 1 Exam Review

Front

What are spindle fibers?

Back

Spindle fibers are structures that form during cell division (mitosis and meiosis) to help separate chromosomes.

Front

What is a deletion mutation?

Back

A deletion mutation is a type of genetic mutation where one or more nucleotides are removed from a DNA sequence.

Front

Which organelle is responsible for photosynthesis in plant cells?

Back

Chloroplasts are the organelles in plant cells that conduct photosynthesis.

Front

What happens to sister chromatids during cell division?

Back

Sister chromatids are pulled apart during mitosis and meiosis.

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in cells.

Front

What is the role of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the endoplasmic reticulum?

Back

The endoplasmic reticulum is an organelle that synthesizes proteins (rough ER) and lipids (smooth ER) and transports them within the cell.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.
