What is the difference between protists bacteria and fungi?
The primary difference between them is their cellular organization. Bacteria are single-celled microbes and are prokaryotes, which means they’re single-celled organisms lacking specialized organelles. In contrast, protists are mostly single-celled eukaryotic organisms that are not plants, fungi, or animals.
Which of the following is a characteristic that all protists share in common?
Characteristics of Protists They are eukaryotic, which means they have a nucleus. Most have mitochondria. They can be parasites. They all prefer aquatic or moist environments.
What makes fungi unique from other organisms?
Historically, fungi were included in the plant kingdom; however, because fungi lack chlorophyll and are distinguished by unique structural and physiological features (i.e., components of the cell wall and cell membrane), they have been separated from plants.
How are animals different from other living organisms protists and fungi )?
They are heterotrophic, generally digesting food in an internal chamber, which distinguishes them from plants and algae. They are also distinguished from plants, algae, and fungi because their cells lack cell walls.
How do protists differ from prokaryotes?
Prokaryotes are usually single-celled organisms. They have plasma membrane surrounding the cell but no membrane bound organelles such as the mitochondria, nucleus or Golgi bodies. Protists are all eukaryotes and therefore all have cell organelles, most of them are single-celled but multi-celled form exists.
What characteristic distinguishes most animal-like protists from other protists?
What characteristic distinguishes most animal-like protists from other protists? Most can move to get food. What characteristic distinguishes plant-like protists from other protists? They use pigments to capture energy from the sun.
What is the meaning of the word heterotroph?
A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.”
Where can heterotrophs be found in the world?
Heterotrophs are all around us—in the oceans, deserts, forests and perhaps even sitting right next to you! Technically, organisms that cannot produce their own food through carbon fixation and depend on other sources of organic carbon to fulfill their nourishment requirements are called heterotrophs.
How are fungi different from the other heterotrophs?
Fungi are a special type of heterotroph—they do not directly ingest their food like other heterotrophs, but instead feed by absorption. Fungi have structures called hyphae, which are similar to plant roots.
How are autotrophs different from heterotrophs and consumers?
Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae , and some types of bacteria . Heterotrophs are known as consumers because they consume producers or other consumers.
