NSBHS 20-21 Plant Structure/Function & Energy Review BIO 1

Front

What are root hairs?

Back

Root hairs are small hair-like structures that increase the surface area of a plant's root system, allowing for greater water and nutrient absorption.

Front

What is the function of stomata in leaves?

Back

Stomata are small openings on the leaf surface that allow gases, such as carbon dioxide and oxygen, to enter and exit the leaf.

Front

What tissue is responsible for protection and preventing water loss in plants?

Back

Dermal tissue plays the role of protection and prevention of water loss in plants.

Front

What is the function of male gametes in plants?

Back

Male gametes are produced by the anthers in flowers and are necessary for plant reproduction.

Front

What is the role of xylem in angiosperms?

Back

Xylem transports water and minerals from the roots to the rest of the plant.

Front

What is the role of phloem in angiosperms?

Back

Phloem transports glucose and other organic nutrients from the leaves to the rest of the plant.

Front

How do root hairs affect a plant's ability to absorb water?

Back

Root hairs increase the surface area of the root system, leading to an increase in the amount of water taken in by the plant.

Front

What is the upper epidermis of a leaf?

Back

The upper epidermis is the outer layer of cells on the top side of a leaf, providing protection and helping to reduce water loss.

Front

What is the function of guard cells?

Back

Guard cells surround stomata and regulate their opening and closing, controlling gas exchange and water loss.

Front

What is the significance of vascular tissue in plants?

Back

Vascular tissue, consisting of xylem and phloem, is essential for the transport of water, nutrients, and food throughout the plant.
