Spontaneous generation that sometimes refers to "abiogenesis" is an idea that life comes from non-living things/components. Whereas biogenesis is a contemporary concept that life can only arise from another living thing.

Cell division, a baby of mice born from adult males and females, etc. are some examples of biogenesis. In contrast, there is no example of spontaneous generation. It remains a theoretical concept.

The plant kingdom is divided into 2 groups vascular and nonvascular. describe each subclass. include key words such as vascular

BaLLatris [955]

<h2>Vascular and Nonvascular Plants </h2>

Explanation:

Kingdom Plantae on the basis of vasculature is divided into two groups-vascular and non-vascular plants .

<u>Vascular plants </u>or tracheophytes have a proper tissue-level organization and true shoot and root structures like leaves, stem, flowers, root etc
The tissue system or vasculature of vascular plants compromises of vascular tissues like tubular vessels – xylem and phloem

The xylem transports nutrients to various parts of the body from the leaves.
Phloem conducts water and other nutrients from the roots to various parts of the plant .

These are flowering plants that include the phanerogams – angiosperms and gymnosperms and bears flowers and fruits like the cedars, pine, clubmosses, lilies, sunflower etc.
Dicots are with tubular vasculature.

Non-vascular plants or bryophytes with an absence of proper tissue-level organization and true shoot or root systems
<u>Nonvascular plants</u> are small. Their transport mechanism is poor due to lack of vascular tissues
These plants are lack proper shoot or root system.
It includes mosses, hornworts etc.
Monocots are plants with scattered tube-like vessels .
