Evidence supporting a charophyte ancestry for plants includes similarities in cell wall composition, chloroplast structure, reproductive features like the formation of a phragmoplast during cell division, and genetic studies that have identified shared gene sequences. Fossil evidence of charophyte-like algae dating back to the Ordovician period further supports this hypothesis. These shared characteristics suggest a close evolutionary relationship between charophytes and land plants.
What else can I help you with?
What are three types of evidence that support the relationship between algae and plants?
Both algae and plants contain chlorophyll, a green pigment that allows them to photosynthesize. They both possess cell walls made of cellulose, a structural component unique to photosynthetic organisms. Algae and plants share similar reproductive structures, such as spores or seeds, which indicate a common ancestry.
What observable traits might green algae and plants share that support the molecular evidence that these two groups are closely related?
Green algae and plants share several observable traits that support their close relationship, including the presence of chlorophyll a and b, which gives them their green color and enables photosynthesis. Additionally, both groups possess similar structures for storing energy, such as starch, and have cell walls made of cellulose. They also exhibit similar reproductive strategies, including the formation of multicellular structures and the use of flagellated sperm. These shared characteristics align with molecular evidence indicating their common ancestry.
Scientists think that plants evolved directly from what kingdom?
Scientists believe that plants evolved directly from a freshwater green algae called charophyte. There are two different types of charophytes, coleochaetales and charales, which strongly resemble earliest land plants.
True or false wegener knew that continental drift explained fossils of tropical plants?
True. Alfred Wegener, the scientist who proposed the theory of continental drift, used the distribution of fossils of tropical plants across continents as evidence to support his idea that the continents were once connected. This was one of the key pieces of evidence Wegener used to support his theory.
What do epiphytic and parastic plants grow on?
Epiphytic plants grow on other plants for support and parasitic plants grow on host plants for support and food both.
Which of these might be used to determine common ancestry of two different species of plants?
fossil evidence :)
The most recent common ancestor of all land plants was probably similar to modern-day members of which group?
Charophyte.

What evidence is there of Pangaea from climate?
The fossil of animals are evidence that support the theory of continental drift.

What did Alfred Wegener use for evidence?
Alfred Wegener used several pieces of evidence to support his theory of continental drift, including the fit of continents like South America and Africa, similar rock formations and mountain ranges across continents, and the distribution of plants and animals. He also looked at evidence from fossils and ancient climate data to support his hypothesis.
What do epiphytic and parastic plants grow on?
Epiphytic plants grow on other plants for support and parasitic plants grow on host plants for support and food both.
What has roots?
All plants, bushes, and trees have roots.In sociology and psychology, "roots" refers to your family and ancestry.
When did vascular plants most likely evolve What is the evidence for the time scale?
Vascular plants most likely evolved around 400-450 million years ago during the Ordovician period. Fossil evidence, including early vascular plant fossils such as Cooksonia, suggests that these plants emerged during this period. Additionally, molecular clock studies also support this time frame for the evolution of vascular plants.
Does chlorophyll pressure help support plants?
Yes, Chlorophyll pressure does help support plants.
