Click on the flashcard to see the answer

What is the function of the plant cell wall?

The plant cell wall provides structural support and protection to the cell while also facilitating communication between cells.

What are the three primary types of plant tissues?

The three primary types of plant tissues are dermal, vascular, and ground tissues.

Describe the role of xylem in plants.

Xylem is responsible for the transport of water and dissolved minerals from the roots to the rest of the plant.

What is the function of phloem in plants?

Phloem transports sugars and other organic nutrients from the leaves to other parts of the plant.

What role do stomata play in plant leaves?

Stomata are small openings on leaves that facilitate gas exchange between the plant and the atmosphere.

How does the cuticle assist plant leaves?

The cuticle provides a protective, waxy layer on leaves to minimize water loss and provide a barrier against pathogens.

What is the primary function of parenchyma cells?

Parenchyma cells are involved in photosynthesis, storage, and tissue repair and regeneration.

What are trichomes, and what function do they serve?

Trichomes are hair-like structures on plant surfaces that protect against herbivores, reduce water loss, and regulate temperature.

Explain the significance of the cell membrane in plant cell functions.

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

What are sclerenchyma cells and their function?

Sclerenchyma cells provide structural support with their thick, lignified walls.

What role does the chloroplast have in plant cells?

Chloroplasts conduct photosynthesis, converting light energy into chemical energy stored as glucose.

How does the vacuole contribute to the plant cell's function?

Vacuoles maintain cell turgor pressure, store nutrients and waste, and degrade materials within the cell.

Differentiate between primary and secondary growth in plants.

PRIMARY growth increases length, focusing on roots and shoots, while SECONDARY growth increases girth, involving cambium activity.

Describe the function of collenchyma cells in plants.

Collenchyma cells provide flexible support to actively growing plant parts without inhibiting growth.

What is the primary distinction between monocot and dicot stems?

Monocot stems have scattered vascular bundles, while dicot stems have vascular bundles arranged in a ring.
