The Nature and Variety of Living Organisms Flashcards
1
Q
What do all living organisms have in common
A
- Movement
- Respiration
- Sensitivity
- Control
- Growth
- Reproduction
- Excretion
- Nutrition
2
Q
Lists the organelles functions as well
What organelles do animal and plant cells both share
A
- Cytoplasm: Chemical reactions occur in the cytoplasm
- Nucleus: Controls the activities of the cell
- Cell membrane: Controls entry and exiting of substances into the cell
- Ribosomes: Proteinsynthesis occurs here
- Mitochondria: Where anaerobic respiration takes place; releases energy
CNCRM
3
Q
What is found in plant cells only
A
- Cell wall: Protects and supports the structure of the cell, made up of cellulose
- Vacuole: Contains dissolved sugars and mineral ions
- Chloroplasts: Carries out photosynthesis
4
Q
What is the difference between eukaryotic and prokaryotic cells
A
- Eukaryotic: (all animal cells) Has membrane bound organelles
- Prokaryotic: (viruses and bacteria) No membrane bound organelles
5
Q
Talk about whether a bacteria is pathogenic or non pathogenic
What is a pathogen
A
- A pathogen is a microorganism that causes diseases
- Bacteria can either be pathogenic (pneumococcus) or non-pathogenic (lactobacillus bulgaricus)
6
Q
Virus
A
- Contains a protein coat which surrounds DNA or RNA
- Unicellular
- Always pathogenic
- Examples are HIV, Influenza, Tobacco Mosaic virus
7
Q
Bacteria
A
- Cell wall, no nucleus; contains nucleoid and plasmids
- Unicellular
- Sometimes pathogenic
- Examples are pneumococcus and lactobacilus bulgaricus
8
Q
Protoctists
A
- Structure can be similar to animal cells (protozoa) or plant cells (algae)
- Can be unicellular or multicellular
- Sometimes pathogenic
- Chlorella (plant like) and Amoeba (more animal like) and Plasmodium (pathogenic because it causes malaria)
9
Q
Fungi
A
- Cell wall made of chitin, hyphae which are thread like structures which form a network called mycelium
- Can be either unicellular or multicellular
- Sometimes pathogenic
- Mucor or mushrooms
- Uses saprotrophic nutrition; they extracellularly secrete enzymes over dead matter which then absorbs nutrients
10
Q
What are the 5 kingdoms
A
- Animal
- Plants
- Bacteria
- Fungi
- Protoctists
APBFP
11
Q
What are the eukaryotic organisms
A
Plants, Animals, Fungi and Protoctists
PAFP
12
Q
What are the prokaryotic organisms
A
Bacteria
13
Q
How are cabohydrates stored
A
- Animals: Glycogen
- Fungi: Glycogen
- Plants: Starch
