Front

What is the function of guard cells in a leaf?

Back

Guard cells control the opening and closing of the stoma, regulating gas exchange and water loss.

Front

What distinguishes protists from bacteria?

Back

Protists are eukaryotes with complex cells, while bacteria are prokaryotes with simpler cells.

Front

What is the primary role of leaves in plants?

Back

Leaves provide a place for photosynthesis to occur, converting sunlight into energy.

Front

What is xylem's role in a plant?

Back

Xylem transports water and minerals from the roots to the leaves.

Front

How can an experiment's validity be improved?

By carrying out multiple trials and increasing the number of samples for each condition.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide and water.

Front

What are the two main types of cells in living organisms?

Back

Eukaryotic cells (with a nucleus) and prokaryotic cells (without a nucleus).

Front

What is the cuticle in plants?

Back

The cuticle is a waxy layer that covers the leaves and stems, helping to prevent water loss.

Front

What is the role of the epidermis in a leaf?

Back

The epidermis protects the leaf and helps regulate gas exchange.

Front

What is the difference between autotrophs and heterotrophs?

Back

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