Are all Archaeplastida multicellular?
Red algae typically exist as multicellular protists that lack flagella; however, they can also exist as unicellular organisms. Green algae are the most abundant group of algae and can be further classified as chlorophytes and charophytes.May 27, 2022
Are Archaeplastida unicellular or multicellular?
Red algae typically exist as multicellular protists that lack flagella; however, they can also exist as unicellular organisms.May 27, 2022
Are Archaeplastida unicellular?
The Archaeplastida vary widely in the degree of their cell organization, from isolated cells to filaments to colonies to multi-celled organisms. The earliest were unicellular, and many groups remain so today.
Are Archaeplastida prokaryotes?
The Archaeplastida are the product of an ancient evolutionary partnership of a single-celled eukaryotic protist with a prokaryotic oxygen-producing photosynthetic bacterium (Delwiche, 1999).
Is red algae a eukaryote or prokaryote?
Red algae are a group of eukaryotic algae which may be unicellular, filamentous, or membranaceous.
What feature do all Archaeplastida have in common?
One of the fundamental and distinctive features of the members of Archaeplastida is the presence of the chloroplasts. They also lack centrioles and have mitochondria. They also have a cell wall and cellulose. The food produced from photosynthesis is stored in the form of starch.Jul 23, 2021
What is the Synapomorphy of all Archaeplastida?
Archaeplastida: Includes Rhodophyta (red algae) and Viridiplantae (green algae and plants). Potential synapomorphies: Chlorophyll a. Presence of cellulose cell walls.
Are Archaeplastida eukaryotic or prokaryotic?
The Archaeplastida (or kingdom Plantae sensu lato "in a broad sense"; pronounced /ɑːrkɪ'plastɪdə/) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes.
What are the 5 supergroups of eukaryotes?
Nearly all of eukaryotic diversity has been classified into 6 suprakingdom-level groups (supergroups) based on molecular and morphological/cell-biological evidence; these are Opisthokonta, Amoebozoa, Archaeplastida, Rhizaria, Chromalveolata, and Excavata.
What was the first eukaryotic supergroup?
Here we demonstrate, by phylogenomic analyses of a 159-protein data set, that G. vulgaris is a member of Rhizaria and is thus the first member of this eukaryote supergroup known to be capable of aggregative multicellularity.Jun 19, 2012
Is eukarya a supergroup?
Currently, the domain Eukarya is divided into six supergroups. Within each supergroup are multiple kingdoms. Dotted lines indicate suggested evolutionary relationships that remain under debate.
