The Variety Of Living Organisms Flashcards
What are cell walls made of
A carbohydrate called cellulose
What are some of the organic compounds made by plants as a result of photosynthesis
Starch- storage carbohydrate that is often found in plant cells
Sucrose- transported around the plant and is sometimes stored in fruits and other plant organs
Five major groups of living organisms
Plants
Animals
Fungi
Protoctists
Bacteria
Some of the variety in the animal kingdom
Vertebrates -
fish,
amphibians,…frogs,toads,newts
reptiles..Crocodile,snakes,lizard,turtle
Birds,
Mammals
Invertebrates -
Sponges
Molluscs
Worms
Starfish
Insects
Crustaceans
How do most animals store carbohydrates in their cells
As a compound called glycogen, found in liver and muscles
Examples of fungi
Mushrooms
Toadstool
Moulds
Yeast
What is the cell wall of a fungi made of
Chitin- the same material that makes the outside skeleton of insects
What is a mushroom or toadstool
The reproductive structure of the organism, called a fruiting body
Under the soil, the mushroom has many fine thread like filament called hyphae
What is hyphae
Thread like filament of cells in fungi
What is mycelium
Network of fungal hyphae
What is a mould
Like a mushroom without a fruiting body,
Just consists of a network of hyphae called mycelium
Feeds by absorbing nutrients from dead ( or sometimes living) material
For example, in soil, rotting leaves, decaying fruit
How do moulds feed
By absorbing nutrients from dead (or sometimes living) material
For example, soil, rotting leaves, decaying fruit…
What is saprotrophic
Type of nutrition where dead organic material is digested outside the body of an organism by extracellular enzymes.
Carried out by fungi and most bacteria
What is protoctista mixed group of eukaryotic organisms that are not plants, animals nor fungi.
Like amoeba
Algae
Mostly unicellular species like bacteria
