Plant Adaptations and Structures

What is the primary function of roots in plants?

• Supporting the leaves, producing flowers, conducting photosynthesis

• Anchoring the plant, absorbing water and nutrients, and storing food.

How do taproots differ from fibrous roots?

• Taproots are shallow, while fibrous roots are deep

• Taproots have a main central root, while fibrous roots consist of many small roots.

• Taproots are thin, while fibrous roots are thick

• Taproots are only found in monocots, while fibrous roots are only found in dicots

Name one adaptation of leaves to reduce water loss.

• Increased stomata density

• Reduced chlorophyll production

• Thickening of the leaf surface

• Waxy cuticle

What is the main function of stems in plants?

• Absorb sunlight and produce energy

• Provide structural support, transport water and nutrients, and store food.

• Attract pollinators for reproduction

• Anchor the plant in the soil

Explain the process of transpiration in plants.

• The main mechanism of transpiration in plants is through the absorption of water from the air through their roots.

• Transpiration in plants occurs through the process of photosynthesis, where water is released as a byproduct.

• Plants lose water vapor through their flowers, creating a positive pressure that draws water down from the leaves.

• Plants lose water vapor through stomata in their leaves, creating a negative pressure that draws water up from the roots through xylem vessels.

What is the purpose of flowers in plants?

• Reproduction

• Photosynthesis

• Regulating temperature

• Protection from predators

Describe the structure of a typical flower.

• Anthers, filaments, ovary, and style.

• Calyx, corolla, and receptacle.

• Sepals, petals, stamens, and pistil.

• Leaves, roots, stem, and branches.

What is the role of chlorophyll in photosynthesis?

• Store excess water for the plant

• Absorb light energy and convert it into chemical energy

• Regulate the temperature of the plant

• Reflect light energy back into the environment

What is the role of stomata in photosynthesis?

• Stomata convert carbon dioxide into glucose during photosynthesis.

• Stomata allow for gas exchange and regulate water loss during photosynthesis.

• Stomata absorb sunlight during photosynthesis.

• Stomata release oxygen during photosynthesis.

What are the functions of the xylem and phloem in plants?

• Xylem and phloem are not involved in nutrient transport.

• Xylem and phloem both transport water and minerals.

• Xylem transports sugars, phloem transports water and minerals.

• Xylem transports water and minerals, phloem transports sugars.
