Biology Midterm Review

Front

What do both prokaryotes and eukaryotes contain?

Back

Ribosomes are present in both prokaryotic and eukaryotic cells, essential for protein synthesis.

Front

What are the main elements found in organic compounds?

Back

Organic compounds primarily contain oxygen, carbon, and hydrogen atoms.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to move substances like glucose across the cell membrane.

Front

What genotype is represented by X^BY in a Punnett square?

Back

X^BY represents a male with a dominant trait in a genetic cross.

Front

What happens to a cell placed in a hypertonic solution?

Back

The cell shrinks in size due to the loss of water as it moves out of the cell.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA.

Front

Define osmosis.

Back

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

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What is a Punnett square used for?

Back

A Punnett square is a tool used in genetics to predict the genotypes of offspring from parental crosses.

Front

What is the role of the cell wall?

Back

The cell wall provides structural support and protection to plant cells, fungi, and some bacteria.
