What is phloem?

Back

Phloem is a type of vascular tissue in plants responsible for the transport of nutrients and food produced by photosynthesis from the leaves to other parts of the plant.

What is a bud scale scar?

Back

A bud scale scar is a ring-like scar on a stem that marks the location where a terminal bud was attached, indicating the start of the year's growth.

Front

What is a leaf scar?

Back

A leaf scar is a mark left on a stem after a leaf has fallen off, indicating where the leaf was attached.

Front

What is a terminal bud?

Back

A terminal bud is the bud located at the tip of a twig, responsible for the growth in length of the stem.

Front

What is a vascular bundle?

Back

A vascular bundle is a part of the transport system in vascular plants, consisting of xylem and phloem tissues that transport water, nutrients, and food.

Front

What is xylem?

Back

Xylem is a type of vascular tissue in plants that transports water and dissolved minerals from the roots to the rest of the plant.

Front

What is the function of the cortex in a stem?

What is the role of the epidermis in a plant stem?

Back

The epidermis is the outermost layer of cells in a plant stem that protects the plant and helps reduce water loss.

Front

What is the significance of the cambium layer?

Back

The cambium layer is a layer of actively dividing cells between the xylem and phloem that contributes to the growth in diameter of the stem.
