Biology Semester 1

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are biological catalysts that speed up chemical reactions in the body without being consumed in the process.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

Define heterotrophs.

Back

Heterotrophs are organisms that cannot produce their own food and must obtain nutrients and energy by feeding on other organisms.

Front

Who was Robert Hooke?

Back

Robert Hooke was a scientist who is credited with being the first person to see and identify cells using a microscope.

Front

What organelles are unique to plant cells?

Back

Chloroplasts and cell walls are organelles found in plant cells but not in animal cells.

Front

What is the function of chloroplasts?

Back

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

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food (e.g., plants), while heterotrophs must consume other organisms for energy.

Front

What is the cell theory?

Back

The cell theory states that all living organisms are composed of cells, and cells are the basic unit of life.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

What are ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA.
