Front

What is the function of stomata in plants?

Back

Stomata are porous openings in the bottom of the leaf that allow for gaseous exchange, enabling the plant to take in carbon dioxide and release oxygen.

Front

What does anaerobic mean in the context of cellular respiration?

Back

Anaerobic refers to the production of ATP without the presence of oxygen.

Front

What are epidermal cells?

Back

Epidermal cells are the outermost layer of cells in a plant that provide protection from outside elements.

Front

Define heterotrophs.

Back

Heterotrophs are organisms that cannot make their own food and must obtain energy by consuming other organisms.

Front

What process do plants use to make glucose?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose.

Front

What is the role of palisade mesophyll in a leaf?

Back

Palisade mesophyll cells are responsible for photosynthesis, as they contain many chloroplasts and are located just below the epidermis.

Front

Explain the term 'cellular respiration'.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs can produce their own food through processes like photosynthesis, while heterotrophs must consume other organisms for energy.

Front

What is the function of the waxy cuticle on a leaf?

Back

The waxy cuticle helps to reduce water loss from the leaf surface and provides a barrier against pathogens.

Front

What is the significance of spongy mesophyll in leaves?

Back

Spongy mesophyll contains air spaces that facilitate gas exchange and help in the diffusion of carbon dioxide and oxygen.
