Plant Structure and Function Concepts

The video provides an overview of plant structure and function, focusing on roots, stems, and leaves. It explains the roles of different root systems, the types of stems, and the process of photosynthesis in leaves. The video concludes with a discussion on plant tropisms, including phototropism, gravitropism, thigmotropism, and hydrotropism.

What is the primary function of roots in plants?

• To attract pollinators

• To perform photosynthesis

• To anchor the plant and absorb water and nutrients

• To produce flowers

Which type of root system is characterized by a single main root?

• Fibrous root system

• Taproot system

• Adventitious root system

• Aerial root system

What is the role of the root cap?

• To perform photosynthesis

• To store nutrients

• To protect the root tip as it grows through the soil

• To absorb sunlight

What is the main purpose of a plant's stem?

• To absorb water

• To support the leaves and transport nutrients

• To produce seeds

• To attract insects

Which type of stem is typically green and flexible?

• Subterranean stem

• Woody stem

• Herbaceous stem

• Aerial stem

Where does photosynthesis primarily occur in a plant?

• In the roots

• In the flowers

• In the leaves

• In the stem

What is the function of stomata in leaves?

• To store nutrients

• To absorb water

• To allow gas exchange

• To produce seeds

What is phototropism?

• A plant's response to touch

• A plant's growth towards light

• A plant's response to gravity

• A plant's growth towards water

How does gravitropism affect plant growth?

• Plants grow towards water

• Plants grow away from the pull of gravity

• Plants grow towards light

• Plants grow towards touch

Which type of tropism involves a plant's response to water?

• Phototropism

• Gravitropism

• Thigmotropism

• Hydrotropism
