Questions and Answers

Why do tomatoes have slightly different shapes at different points on a stem?

  • Genetic mutations cause each tomato to grow differently,
  • The tomato plant prioritizes nutrient delivery based on ripeness.
  • They receive varying amounts of sunlight depending on their position.
  • The cells divide and enlarge differently at different parts of a stem. (correct)

Some cells also interpret the quality of light.

Sunbeam Intensifier

Area where sunbeam is intercepted at right angles to increase the intensity of light.

Condensing lenses

Structures used to make the sunbeams of cells easier to see. They perpendicular to the cells.

Study Notes

  • Some deeper ocean creatures use bioluminescence, which is light created by a chemical reaction inside a living organism, to attract prey in the dark depths of the ocean.
  • Bioluminescence is used to make the silhouette of an animal harder to see.
  • Some animals also use bioluminescence to communicate.
  • Examples: flashlight fish and angler fish use bioluminescence.
  • Angler fish and flashlight fish are luminous bacteria living within their bodies.
