Front

Which plant organelle transforms light into glucose to use as food?

Back

Chloroplasts are the organelles in plant cells that convert light energy into chemical energy in the form of glucose through photosynthesis.

Front

What happens when you place an over ripe banana in a fruit bowl with other fruit?

Back

Ethylene gas released by the overripe banana accelerates the ripening process of other fruits in the bowl.

Front

In a cell, what receives, packages and distributes materials?

Back

The Golgi body (or Golgi apparatus) is responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

Front

Which plant hormone is a gas?

Back

Ethene (or ethylene) is a plant hormone that acts as a signaling molecule and is involved in the regulation of fruit ripening.

Front

What is the jelly-like substance inside a cell called?

Back

Cytoplasm is the gel-like fluid inside the cell membrane that contains organelles and is the site of many cellular processes.

Front

What is the primary function of mitochondria in plant cells?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration, providing energy for cellular activities.

Front

What role do vacuoles play in plant cells?

Back

Vacuoles are storage organelles that hold various substances, including nutrients, waste products, and help maintain turgor pressure in plant cells.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the function of auxins in plants?

Back

Auxins are plant hormones that regulate growth and development, influencing processes such as cell elongation, root formation, and fruit development.

Front

What is the significance of gibberellins in plant growth?

Back

Gibberellins are hormones that promote stem elongation, seed germination, and flowering, playing a crucial role in plant growth and development.
