Biology Midterm Review (Check-in 1 - S25)

Front

What is the function of phloem tissue in plants?

Back

Phloem tissue is responsible for transporting food (sugars) from the leaves to the stems and roots.

Front

What is the function of xylem tissue in plants?

Back

Xylem tissue is responsible for transporting water and minerals from the roots to the stems and leaves.

Front

How does DNA activation affect cell differentiation in plants?

Back

DNA activation leads to the expression of specific genes, such as activating the gene for transporting water in xylem cells and deactivating it in phloem cells.

Front

What is a DNA fingerprint?

Back

A DNA fingerprint is a unique pattern of DNA sequences that can be used to identify individuals and determine genetic relationships.

Front

What is the main purpose of genetically engineering bacteria to produce human insulin?

Back

The main purpose is to help treat diseases in people, particularly diabetes.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to a potato strip placed in distilled water?

Back

Water molecules move into the potato's cells, causing the strip to increase in length.

Front

What happens to a potato strip placed in salted water?

Back

Water molecules move out of the potato's cells, causing the strip to decrease in length.

Front

What is the main purpose of meiosis?

Back

The main purpose of meiosis is to create genetic diversity and produce haploid gametes for sexual reproduction.

Front

What is genetic diversity?

Back

Genetic diversity refers to the variety of genes within a species, which contributes to the adaptability and survival of the species.
