Do protoctista have cell walls?
Some protoctista have cell walls made of various materials, like cellulose or silica, while others do not have cell walls. The presence or absence of cell walls in protoctista can vary depending on the specific species.
Why multicellular algae were previously placed in plants but now in protoctist?
why multicellular algae wre previously in plant but now in protoctista
Why is kingdom protoctista difficult to classify what is the basis of their grouping in kingdom protoctista give example of each of its group?
Kingdom Protoctista is difficult to classify because it consists of diverse organisms with unique characteristics that don't fit neatly into other kingdoms. They are grouped based on mostly on their mode of nutrition, locomotion, and reproduction. For example, Protozoa: Unicellular organisms that primarily obtain nutrients through phagocytosis, such as Amoeba. Algae: Photosynthetic protists that can be unicellular or multicellular, like Chlamydomonas. Slime molds: Protists that exhibit characteristics of both fungi and amoebas, such as Physarum polycephalum.
Why marine protoctista have no contractile vacoule?
Marine protoctista typically lack contractile vacuoles because they inhabit environments where the osmotic pressure is balanced, such as seawater. In these conditions, the intake of water through osmosis is minimal, reducing the need for a structure to expel excess water. Instead, these organisms have adapted to regulate their internal environment through other cellular mechanisms. Consequently, the absence of a contractile vacuole is an evolutionary response to their saline habitat.
What are some examples of a phenol?
Some examples of phenols include phenol itself (hydroxybenzene), cresol, guaiacol, and catechol. These compounds contain a hydroxyl group attached to a benzene ring.
Do protoctista have cell walls?
Some protoctista have cell walls made of various materials, like cellulose or silica, while others do not have cell walls. The presence or absence of cell walls in protoctista can vary depending on the specific species.
What do protoctista have in common with prokaryotes?
Protoctista and prokaryotes both lack a true nucleus and membrane-bound organelles. They are both unicellular organisms, although some protoctista may be multicellular. Additionally, they can both be found in various environments and play important roles in ecosystems.
Is protoctista a living thing?
Yes
Does a protoctista cell have a nucleus?
yes
How is microorganism of Monera kingdom different from Protoctista kingdom?
Protoctista are eukaryotic, meaning they have a true nucleus. Monera are prokaryotic, meaning they have no nucleus.
Common name of kingdom protista?
The kingdom Protista (also known as Protoctista) includes organisms such as Protozoa, Algae and Fungus.
What type of habitat does protoctista live in?
water/liqiud
What is protoctista?
Protoctista is an outdated biological kingdom that encompassed a wide variety of eukaryotic organisms that did not fit into the plant, animal, or fungi kingdoms. It is no longer considered a valid taxonomic group due to advancements in molecular biology and the understanding of phylogenetic relationships among eukaryotes.
Plantae and animaila are 2 examples of what?
Kingdoms of living organisms Here is a complete lists of all the kingdoms 1. Prokaryotae 2. Protoctista 3. Fungi 4. Plantae 5. Animalia
What is the Protoctista classification?
The term Protoctista is an outdated kingdom classification that encompassed various eukaryotic organisms that didn't fit neatly into other kingdoms such as animals, plants, or fungi. It has since been replaced by more specific and accurate classifications based on genetic and evolutionary relationships.
What are the 5 kingdoms of the world?
animal, plant, fungi, protoctista and prokaryotes
What kingdoms that are made up of members without a nucleus in their cells?
Protoctista Kingdom
