Plant Stem Review

Front

What is the main function of the phloem in plants?

Back

The phloem carries dissolved sugars from the leaves to the growing regions of the plant.

Front

What are the functions of the plant stem?

Back

The plant stem serves as a site for nutrient transport, supports the plant, and can act as a food reserve.

Front

What part of the plant cell provides rigidity to the stem?

Back

The cell wall provides the rigid structure of a plant stem.

Front

What is the role of xylem in plants?

Back

Xylem transports water and minerals from the roots to the leaves.

Front

Define translocation in the context of plants.

Back

Translocation is the movement of nutrients and sugars through the plant, primarily via the phloem.

Front

What is the primary role of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into energy.

Front

How do stems contribute to photosynthesis?

Back

While stems do not primarily perform photosynthesis, they support leaves, which are the main sites of photosynthesis.

Front

What is the difference between primary and secondary growth in stems?

Back

Primary growth increases the length of the stem, while secondary growth increases its thickness.

Front

What is the significance of the cambium layer in plant stems?

Back

The cambium layer is responsible for the production of new xylem and phloem cells, contributing to secondary growth.

Front

What are the main components of a plant stem?

Back

The main components of a plant stem include the epidermis, cortex, vascular bundles (xylem and phloem), and pith.
