What is the role of xylem in plants?

Back

Xylem is responsible for transporting water and minerals from the roots to the shoot system of the plant.

Front

What is the function of phloem in plants?

Back

Phloem transports carbohydrates, primarily glucose, from the leaves to other parts of the plant, including fungi in symbiotic relationships.

Front

How do plants and fungi benefit from their symbiotic relationship?

Back

Plants provide carbohydrates to fungi, while fungi supply minerals and water to plants, enhancing growth and survival for both.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

Why do plants grow toward sunlight?

Back

Plants grow toward sunlight to maximize photosynthesis, which is essential for their energy production and growth.

Front

What is the genetic code?

Back

The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA) is translated into proteins.

Front

What carries the instructions for individual traits in DNA?

Back

The nucleotide sequences within DNA strands carry the instructions for individual traits.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

What does the codon AUG represent?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for the amino acid Methionine.

Front

What is the significance of the stop codon in protein synthesis?

Back

The stop codon signals the termination of protein synthesis, indicating that the polypeptide chain is complete.
