Are plants unicellular or multi cellular.
- ## Multicellular
Do plants contain cholorplasts?
Yes and are able to carry out photosynthesis
What are plant cell walls made out of?
Cellulose
What do plants store carbohydrates as?
Starch or sucrose
Are animals unicellular or multicellular?
Multi cellular
Do animal cells contain chloroplasts?
No and does not perform photosynthesis
What are animal cell walls made out of?
They dont have them
What do animals often store carbohydrate as?
Glycogen
Can fungi carry out photo synthesis?
No
What are fungi bodys organises in?
Mycelium made from thread-like hyphae which contain may nuclei
Are fungi unicellular or multi cellular?
Some are single celled
What are fungi cell walls made from?
Chitin
How do fungi feed?
Extracellular secretion of digestive enzymes onto food material and absorbsion of the organic products this is saprotrophic nutrition
What do fungi usually store carbohydrate as?
Glycogen
What are protoctists?
Microscopic single celled organisims
What pathogen causes malaria?
Plasmodium
What are bacteria?
Microscopic single celled lrganisims
What do bacteria contain?
Cell wall, cell membrane, cytoplasm and plasmids, no nucleus but contain a circular chromosome of DNA
Do bacteria carry out photosynthesis?
Some do but mose fee off other living or dead organisms
What is a pathogen?
Any disease causing fungi, bacteria, protoctists or virus’s
Are viruses living?
No, they are small particles, smaller than bacteria, they are parasitic and can only reproduce inside living cells, they can infect evry type of living organism
What is a viruses cellular structure?
No cellular structure, but have a protein coat, and a nucleic acid that is either DNA or RNA
