Ecology S1 Final Exam

Front

Which organelle is found in plant cells but NOT in animal cells?

Back

Chloroplast

Front

What type of solution was the yellow egg in if it was in a hypertonic solution?

Back

The yellow egg was in a hypertonic solution, meaning it had a higher concentration of solutes compared to the inside of the egg.

Front

What does Complete Dominance mean in genetics?

Back

Complete Dominance occurs when the dominant allele completely masks the effect of the recessive allele.

Front

What is ATP and how many phosphates does it have?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells and has 3 phosphates.

Front

What is osmosis?

Back

Osmosis is the movement of water through a selectively permeable membrane.

Front

Define hypotonic solution.

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, leading to water moving into the cell.

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, causing water to move out of the cell.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the difference between ADP and ATP?

Back

ADP (Adenosine Diphosphate) has 2 phosphates, while ATP has 3 phosphates, making ATP a higher energy molecule.

Front

What is the significance of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
