What is meristematic tissue and where is it found in plants?

Reveal answer ↓

What it is

Meristem is a plant's growth tissue - young cells that keep dividing at tips and edges.

Answer

Meristematic tissue is made of small, thin-walled cells that keep dividing to help the plant grow. It is found at the growing regions - apical meristem at the tips of roots and shoots (which increases length) and lateral meristem or cambium (which increases thickness). Because its cells divide actively, they have dense cytoplasm and no large vacuoles.

  • •Dividing cells responsible for growth
  • •Apical meristem at root/shoot tips (length)
  • •Lateral meristem/cambium (thickness)
  • •Dense cytoplasm, actively dividing

Why learn this

It's why plants grow taller and thicker all their lives, and how grafting and pruning work.

💡 Memory trick

Apical meristem at the tips (length); lateral meristem sideways (girth).

What are xylem and phloem? State the function of each.

Reveal answer ↓

What it is

Xylem and phloem are the transport tissues of plants - xylem carries water, phloem carries food.

Answer

Xylem and phloem are the two conducting (vascular) tissues in plants. Xylem carries water and dissolved minerals upward from the roots to the leaves. Phloem transports the food (sugar) made in the leaves during photosynthesis to all other parts of the plant. Together they form the plant's transport system.

  • •Xylem: carries water and minerals up from the roots
  • •Phloem: carries food from leaves to the whole plant
  • •Both are conducting (vascular) tissues

Why learn this

They are the plant's plumbing - how water rises from the roots and food reaches every part.

💡 Memory trick

Xylem = water UP from roots; Phloem = Food (from leaves) to the whole plant.
