Plant Systems Flashcard

Front

What is the cotyledon?

Back

The cotyledon is the part of a seed that provides nutrients to the developing plant embryo and is often the first leaf to appear during germination.

Front

What are xylem and phloem?

Back

Xylem and phloem are types of vascular tissue in plants. Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports food (sugars) produced by photosynthesis.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use carbon dioxide and water, in the presence of sunlight, to produce glucose (food) and oxygen.

Front

What does it mean for a seed to be dormant?

Back

Dormancy in seeds refers to a state of inactivity or rest, where the seed is alive but not actively growing until conditions are favorable for germination.

Front

What is the main function of leaves in plants?

Back

The main function of leaves is to provide a site for photosynthesis, where plants convert sunlight into chemical energy.

Front

What role does transpiration play in plants?

Back

Transpiration is the process by which water vapor is released from plant leaves into the atmosphere, helping to regulate temperature and facilitate nutrient transport.

Front

What is the function of roots in plants?

Back

Roots anchor the plant in the soil, absorb water and minerals, and store food.

Front

What is the significance of vascular tissue in plants?

Back

Vascular tissue is crucial for the transport of water, nutrients, and food throughout the plant, allowing it to grow and thrive.

Front

What is the difference between monocots and dicots?

Back

Monocots have one cotyledon, parallel leaf veins, and flower parts in multiples of three, while dicots have two cotyledons, net-like leaf veins, and flower parts in multiples of four or five.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that captures sunlight, enabling the process of photosynthesis to occur.
