8 of 25
Example?
HIV, tobacco mosaic virus
9 of 25
Bacteria-is it single celled?
yes
10 of 25
What does a bacteria cell contain?
cell wall, cytoplasm, and PLASMIDS, a circular chromosome of DNA (no nucleus)
11 of 25
Can they carry out photosynthesis?
Some can
12 of 25
Example?
Lactobacillus bulgaricus (rod-shaped bacteria used in yogurt production), Pneumococcus (a spherical bacterium that acts as the pathogen causing pneumonia)
13 of 25
Protoctists-single-celled?
YEAHHH

Examples
Amoeba, Chlorella, pathogen-Plasmodium-causing maiaria

Fungi-can they carry out photosynthesis?
NOO (haha im tricking you) :P
16 of 25
What is the structure, and what is made in order to get into this structure?
mycelium is made, the structure is hyphae (thread-like)-contains a lot of nucleis
17 of 25
What is the cell wall made of?
chitin
18 of 25
Single celled?
some

nutrition?
saprotrophic nutrition-they feed by extracellular secretion of digestive enzymes on to food material and absorption of the organic products
20 of 25
What can they possibly store carbohydrate as?
glycogen
21 of 25
Examples?
Mucor, yeast
22 of 25
Diseases caused by fungi?
Athlete's foot, ringworm
