Meristem Tissues and Growth

Biology

Not quite remember

I easily remember

Meristematic tissue

Undifferentiated living tissues in plants that are responsible for plant growth.

Types of meristematic tissue

Apical meristem & lateral meristem

Location of the apical meristem tissue

At the tips of the shoots and roots

Lateral meristem tissues consist

Vascular cambium & cork cambium

Shoot apical meristem

Root apical meristem

Three zones of cell growth

Cell division zone, cell elongation zone & cell differentiation zone

Primary growth

Growth that occurs after germination and is experienced by all plants to increase stem and root length.

Secondary growth

Occurs mainly in eudicots and a small number of monocots (shrub) to increase the circumference or diameter of plant stem and root

Location of cambium vascular

Located between phloem and xylem tissues in vascular bundles
