Front

What is a chromosome packaged with?

Back

DNA

Front

What component in photosynthesis is not recycled and must be constantly available?

Back

Energy

Front

Why is spring water better than distilled water for amebae?

Back

Spring water is isotonic.

Front

What is the structure indicated by the arrow in the image?

Back

Central vacuole

Front

What is the process of programmed cell death called?

Back

Apoptosis

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to convert carbon dioxide and water into glucose and oxygen.

Front

What is the difference between hypotonic, hypertonic, and isotonic solutions?

Back

Hypotonic solutions have a lower concentration of solutes compared to the cell, causing it to swell; hypertonic solutions have a higher concentration, causing it to shrink; isotonic solutions have equal concentrations, maintaining cell size.

Front

What is the function of the cell wall?

Back

The cell wall provides structural support and protection to the cell, and helps maintain its shape.

Front

What is apoptosis and why is it important?

Back

Apoptosis is programmed cell death that helps eliminate damaged or unnecessary cells, maintaining healthy tissue.
