Plants are primarily divided into two main classes: vascular and non-vascular plants. Vascular plants, which include ferns, conifers, and flowering plants, have specialized tissues for transporting water and nutrients. Non-vascular plants, such as mosses and liverworts, lack these tissues and typically rely on diffusion for the movement of substances. This classification helps in understanding their structure, function, and ecological roles.
False. Unlike the cornea, which is avascular (lacking blood vessels), the lens of the eye is also avascular. Both structures rely on the surrounding fluids and tissues for nourishment, but they do not contain blood vessels. The lens is transparent and its avascular nature is essential for its optical clarity.
No, hornworts do not have cones for their reproductive structures. Instead, they reproduce using small, elongated sporangia that are typically found on stalks. These sporangia release spores for reproduction, distinguishing hornworts from other plant groups that utilize cones. Hornworts are non-vascular plants and belong to the division Anthocerotophyta.
Roots can be identified from their internal structure through the following ways: Root Cap: The presence of a root cap at the tip, which protects the growing root as it penetrates the soil, is a key identifying feature. Vascular Tissue Arrangement: Roots typically exhibit a distinct arrangement of vascular tissues, with xylem and phloem organized in a central cylinder, unlike stems where they are arranged in a ring. Cortex and Endodermis: The presence of a cortex surrounding the vascular tissue and an endodermis, which regulates water and nutrient uptake, is characteristic of roots. Storage Structures: Many roots contain specialized storage tissues, such as parenchyma cells that store starch or other nutrients, which can help differentiate them from stems.

vascular
vascular tissue gives plants structures and sends the water and minerals to the top.
Roots, seeds and true xylem and phloem elements are absent in non-vascular plants.
They are vascular because they have tube-like structures in them that carry nutrients through the plant. NON-vascular plants have no tube-like structures so they must be close to the ground. NON-vascular plants do not have roots, but instead have rhizoids. Edited answer: Because bamboo are tall terestrial plants belong to angiosperms

Prothallus
vascular plants have tube-like structures that carry the water from the roots to the leaves.
