Periderm is composed of cork cambium, secondary cortex and cork.

Here the xylem is towards the inner side surrounded by the phloem. This is the characteristic of dicot stems.

Support is provided by the dead tissue called sclerenchyma.

Many layered protective epidermis is found in banyan leaf.

This occurs in the leaves of submerged plants where stomata are not needed.

An annual formation of wood in plants, consisting of two concentric layers, one of springwood and one of summerwood, resulting in annual ring formation helped by intercalary cambium.

A thin hair-like outgrowth of an epidermal cell of a plant root that absorbs water and minerals from the soil is called root hair. They arise from epiblema, which is the outer protective covering of the roots.

Trapa is a rooted, floating plant that invades shallow to deep, fresh water habitats in the northeastern United States.

This is the main characteristic of stems where the metaxylem is towards the periphery and protoxylem is in the centre.

A leaf gap is a space in the stem of a plant through which the leaf grows. It is found in the nodes.

A hydathode is a type of secretory tissue in leaves, usually found in angiosperms, that secretes water through pores in the epidermis or margin of leaves, typically at the tip of a marginal tooth or serration.

Epidermal cells do not contain chloroplast but guard cells contain chloroplast and thus, help in photosynthesis.

This layer contains barrel-shaped cells with the special thickenings in them in the form of casparian strips. Cells without this strips are called as passage cells.

Lateral roots arise from it. Pericycle is present beneath the endodermis.

It is the main character of monocot root.
