Common Features Of Eukaryotic Organisams Flashcards
What are the defining characteristics of plants?
Multicellular organisms with chloroplasts, capable of photosynthesis, cellulose cell walls, store carbohydrates as starch or sucrose
How do animals differ from plants in terms of cellular structure?
Animal cells do not contain chloroplasts, have no cell walls, and usually have nervous coordination
Animals store carbohydrates as glycogen. Examples include mammals like humans and insects like houseflies and mosquitoes.
What is the structure of fungi and how do they obtain nutrients?
Fungi are organized into a mycelium made from hyphae, have cell walls made of chitin, and obtain nutrients through saprotrophic nutrition
They secrete digestive enzymes onto food and absorb organic products. Examples include Mucor and yeast.
What type of nutrition do fungi exhibit?
Saprotrophic nutrition
This involves extracellular secretion of digestive enzymes and absorption of nutrients.
What are protoctists?
Microscopic single-celled organisms that may resemble animal or plant cells
Examples include Amoeba, which has animal-like features, and Chlorella, which has chloroplasts.
What is a pathogenic example of a protoctist?
Plasmodium
It is responsible for causing malaria.
Fill in the blank: Animals usually store carbohydrates as _______.
glycogen
True or False: Fungi can carry out photosynthesis.
False
What is the body structure of fungi primarily made of?
Mycelium made from thread-like structures called hyphae
Fill in the blank: Protoctists include single-celled organisms like _______ and _______.
Amoeba, Chlorella
What do plants and protoctists have in common?
Both can contain chloroplasts
This enables some protoctists like Chlorella to perform photosynthesis similar to plants.
