What type of organisms does the Fungi Kingdom primarily consist of?
Most are multicellular eukaryotes
How do fungi differ from plants?
Do not undergo photosynthesis, no chloroplasts or chlorophyll, are not autotrophs, are heterotrophs
How do fungi reproduce?
By spores (not seeds)
Give examples of good fungi.
- mushrooms
- yeast
- bleu cheese
- penicillin
Give examples of bad fungi.
- mold
- mildew
- athlete’s foot
- ringworm
What are the characteristics of the Plant Kingdom?
Multicellular, autotrophic, eukaryotes that undergo photosynthesis
Define photosynthesis.
Process in which plants and many other producers/autotrophs use raw materials (light energy, carbon dioxide, and water) and produce oxygen
What is chlorophyll?
Green, light-trapping pigment in a plant’s chloroplasts important for photosynthesis
What are stomata?
Tiny openings in a plant’s epidermis/leaf through which gases enter and exit
How are plants divided into major groupings?
- Simple
- Complex
What are the characteristics of simple plants?
- Nonvascular
- Small, low to ground
- Lack real roots, stems, leaves
- Reproduce by spores
Give examples of simple plants.
- Ferns
- moss
- liverwort
What are the characteristics of complex plants?
- Vascular
- Have roots, stems, and leaves
- Reproduce by seeds
What are gymnosperms?
Plants with uncovered seeds, such as cone-bearing trees
What are angiosperms?
Plants with covered seeds that produce flowers
What is a pistil?
The female reproductive organ that contains the stigma, style, ovary, and ovule
What is a stamen?
The male reproductive organ consisting of an anther and filament, where pollen is produced
What is pollination?
The transfer of pollen to allow fertilization
What are the two main groups of animals?
- Vertebrates
- Invertebrates
What are the characteristics of vertebrates?
Have a backbone
Give examples of vertebrates.
- Fish
- Amphibians
- Reptiles
- Birds
- Mammals
What are the characteristics of invertebrates?
Do not have a backbone
Give examples of invertebrates.
- Sponges
- Cnidarians
- Worms
- Mollusks
- Arthropods
- Echinoderms
What are the characteristics of fish?
- Cold-blooded
- Lay eggs
- Must live in water
