Oct 31, 2023 · Land plants, which are called embryophytes, are classified into two major groups according to the absence or presence of vascular tissue. Plants that lack vascular tissue, which is formed of specialized cells for the transport of water and nutrients, are referred to as non-vascular plants or bryophytes.

Informally, land plants can be classified into the groups listed in Table below. Major divisions and types of modern land plants are organized in this table. Why do the first five types of plants require a moist habitat? The most basic division is between nonvascular plants and vascular plants.

Place and identify the clade land plants on a phylogenetic tree within the domain EukaryaDefine traits common to (nearly) all land plants taxa, and explain how these traits are adaptations to life on landDifferentiate between the four major land plant taxa using key adaptations specific to each groupExplain how specific adaptations allowed different land plant taxa to exploit increasingly dry environmentsWe have already spent quite a bit of time considering the evolutionary tree of life and the three domains of life, but we have focused mostly on domain-level evolutionary innovations that occurred in the Archaean and Proterozoic Eons. Now we will move into the Phanerozoic Eon (the current eon) and narrow in on one specific lineage of multicellular ...
The information below was adapted from OpenStax Biology 25.1 The ancestor of all land plants was an aquatic, green algal-like species with a cell wall composed of cellulose. Living in the water provides a number of advantages compared to life on land: 1. In water or near it, plants can absorb water from their surroundings with no need for any speci...
The information below was adapted from OpenStax Biology 25.1 Before we discuss evolution of plant lineages over geologic time, first let’s briefly review the relevant eras and periods of the Phanerozoic. The Phanerozoic is the Eon we are currently in, and it is divided into three Eras: the Paleozoic (oldest era), the Mesozoic (middle era) and Cenoz...
The green algae and land plants are grouped together into a subphylum called the Streptophyta, and thus are called Streptophytes. In a further division, land plants are classified into two major groups according to the absence or presence of vascular tissue, as detailed in Figure 25.6.
The evolutionary classification of land plants . Land plants evolved from a group of green algae, possibly as early as 500–600 million years ago. Their closest living relatives in the algal realm are a group of freshwater algae known as stoneworts or Charophyta.
Land plants are classified into two major groups according to the absence or presence of vascular tissue, as detailed in Figure 7. Plants that lack vascular tissue formed of specialized cells for the transport of water and nutrients are referred to as nonvascular plants .
In general, land plants are classified into two major groups according to the absence or presence of vascular tissue, that is xylem and phloem for transporting water, nutrients, and food around the plant (Fig 3).
