1. The Nature And Variety Of Living Organisms Flashcards
What groups of organisms are eukaryotic?
Animals plants fungi and protoctists
What groups of organisms are prokaryotic?
Prokaryotes (bacteria)
Are plants multicellular or single called?
Multicellular
Do plants contain chloroplasts?
Yes
Can plants photosynthesise?
Yes
What are the cell walls of plants made of?
Cellulose
How do plants store carbohydrates?
As starch or sucrose
Give an example of a plant.
Cereals such as Maize or Barley
Herbaceous legumes such as peas or beans
Are animals single called or multicellular?
Multicellular
Are plants eukaryotic or prokaryotic?
Eukaryotic
Are animals eukaryotic or prokaryotic?
Eukaryotic
Can animals photosynthesise?
No
Do animal cells contain chloroplasts?
No
What are animal cell walls made of?
They dont have cell walls ;)
What do animals usually have which allows them to move and adapt to surroundings?
Nervous coordination
How do animals are carbohydrates?
As glycogen
Give examples of animals.
Mammals : humans etc.
Insects : housefly’s and mosquitos
Can fungi photosynthesise?
No
Are fungi eukaryotic or prokaryotic?
Eukaryotic
How are the bodies of fungo organised?
Organised into mycelium made from thread like structures called hyphae which contains many nuclei
Examples of single-celled fungi
Yeast
What are the cell walls of fungi made of?
Chitin
How do fungi feed and what is this process called?
Feed by extracellular secretion of digestive enzymes ont food material and absorption of the organic products. This is called saprotrophic nutrition.
How do fungi store carbohydrates?
As glycogen
Examples of fungi
Mucor - has the typical fungal hyphae structure
Yeast - single-celled
Are protoctists eukaryotic or prokaryotic?
Eukaryotic
How big are protoctists?
Microscopic
Are protoctists single-celled or multicellular?
Single-celled
Where does amoeba live?
In pond water
What is amoeba an example of?
A protoctist
What other kind of organism are some protoctists similar to?
Some are like animal cells and some are like plant cells (have chloroplasts)
Give examples of protoctists
Chlorella - like a plant cell
Amoeba - like an animal cell
Plasmodium - pathogenic responsible for causing malaria
What types of organisms can be pathogens?
Fungi, viruses, bacteria and protoctists
Are viruses living or non living?
Non-living
Are viruses bigger or smaller than bacteria?
Smaller
