Carbohydrates and Leaf Structure

Front

What are carbohydrates?

Back

Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They are a primary source of energy for living organisms.

Front

What are the main types of carbohydrates?

Back

The main types of carbohydrates are monosaccharides (simple sugars), disaccharides (two sugar units), and polysaccharides (long chains of sugar units).

Front

What is the function of stomata in leaves?

Back

Stomata are small openings on the underside of leaves that allow for the exchange of gases, such as oxygen and carbon dioxide, between the plant and the environment.

Front

How do polysaccharides differ from monosaccharides and disaccharides in terms of energy storage?

Back

Polysaccharides are made up of long chains of sugar molecules, allowing them to store more energy compared to monosaccharides and disaccharides, which are shorter and less complex.

Front

What is the role of the palisade mesophyll in a leaf?

Back

The palisade mesophyll is a layer of tightly packed cells in the leaf that contains chloroplasts and is primarily responsible for photosynthesis.

Front

What is the spongy mesophyll and its function?

Back

The spongy mesophyll is a layer of loosely arranged cells in the leaf that contains air spaces, facilitating gas exchange and allowing for the diffusion of gases.

Front

What is the difference between autotrophs and photoautotrophs?

Back

Autotrophs produce their own food, while photoautotrophs specifically use light energy to produce food through photosynthesis.

Front

What is the significance of chloroplasts in leaf cells?

Back

Chloroplasts are organelles that contain chlorophyll and are responsible for capturing light energy to convert carbon dioxide and water into glucose during photosynthesis.

Front

How do xylem and phloem function in plants?

Back

Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports sugars and nutrients produced during photosynthesis.

Front

What is the process of 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.
