What is the difference between Eubacteria and Archaebacteria
Eubacteria- found everywhere
Archaebacteria- live in extreme environments
Where do fungi often live?
Moist environments
Are plants autotrophs or heterotrophs? Explain what this means
Plants are autotrophs meaning they create their own energy using the sun in a process called photosynthesis
What are two main groups of animals?
- Vertebrate
- Invertebrate
What does survival of the fittest mean
Survival of the fittest: refers to animals who are best able to survive in their environment
What are the 3 main shapes of Monera?
Cocci (spheres)
Bacilli (rods)
Spirilla (spirals)
Name two positive and two negative types of fungi
Positive: yeast, penicillium
Negative: Athlete’s foot, mold, mildew
What are the 5 main parts of plants (be able to draw and label)
What is the main job of leaves?
Flower
Roots
Stem
Leaves
Seeds
The main job of leaves is to make food for the plants through photosynthesis. This is where the chloroplasts which have a chemical called chlorophyll in them and they trap the energy from the sun
What are 5 types of vertebrates
Fish (cold blooded, live in water)
(shark, salmon,tuna, jackfish)
Amphibians(cold blooded, begin in water and develop lungs for land)
(toads, frogs, salamanders)
Reptiles (cold blooded, scales, hard shelled eggs)
(crocs, alligator, snake, turtle)
Birds (warm blooded, wings/feathers, hard shelled eggs)
(blue jay, robin, swallow, duck)
Mammals (warm blooded, hair or fur, nurse their young, live births)
Humans, donkey, horse, cow, bats
What is evolution
The process that involves organisms changing over time and can sometimes split into new species
The theory of evolution explains why animals and plants are so good at surviving in their environments
What are 3 ways “animal-like” protists can move?
Cilia
Little hairs around exterior that move it
Flagellum
Whiplike tail that pushes it forward
Pseudopods
Movements of cell membrane creating an arm to drag it
How do fungi reproduce?
Reproduce through spores
What are 2 kinds of roots and some examples of each (be able to draw)
2 types of roots:
Fibrous roots (grass)
Tap root (carrot)
What are the 4 main types of invertebrates and know some examples of each
Molluscs (soft body with hard outer shell)
Snail, oyster, claims, squids, octopus
Sponges (large pores that live in water, headless and nerveless, Simplest invertebrates)
No specific names- live mostly in ocean
Worms (segmented or flat)
Segmented-earthworm, flat-tapeworm
Anthropods (jointed legs, segmented bodies, hard outer shell)
Myriapods such as centipedes and millipedes, arachnids like spiders, insects, crustaceans like crabs and lobster
What is an adaptation?
A process that occurs through evolution and makes living things become suited to surviving in a particular environment
What are three types of Protists? and describe each
Animal-like
Called protozoa
Heterotrophs
Plant-like
Autotrophs - create own food through sun energy
Fungi-like
Attack crops
heterotrophs
Are fungi:
- Unicellular or Multicellular or Both
- Eukaryotic or Prokaryotic
-Heterotroph or Autotroph
Unicellular or multicelluar
Eukaryotic (has a nucleus)
Heterotroph
What are 3 ways seeds can get dispersed? Give an example of each
3 ways seeds can be dispersed:
Wind (maple seeds, milkweed)
Mammals (burs, hickory nut, acorn)
Water (coconut)
Who is Charles Darwin and what did he create
Charles Darwin developed the theory of evolution and the idea of natural selection
What are two types of adaptations (and some examples of each)
Structural: Physical features that help an animal or plant survive
Fur colour
Webbed feet
A giraffes long neck
Behavioural
Migration
hibernation
What are two ways Eubacteria can be classified based on how they survive? Understand what these words mean
How does Archaebacteria get energy?
Eubacteria
aerobic: requires oxygen to survive
Anaerobic: does not require oxygen to survive
Autotroph: create own energy or food
Heterotroph: must eat others to gain energy
Archaebacteria
Chemosynthetic: produce energy from chemicals
What is pencillium and why is it famous?
A mold that is used to fight/kill bacteria in diseases
It is used in medicines
Created by Alexander Fleming
What are the two ways plants can be categorized? Describe the differences
Nonvascular
Do not contain leaves or roots
Absorb water as it passes through it cells into the plant body
Vascular
Uses roots and tube-like structures to move water throughout the plant
Has leaves, roots, and stems
Ex. Celery
How is genetic variation linked to evolution
If all the individuals of a species had the same genes, evolution would not exist.
No changes could happen over time as everyone would look the same
Evolution relies on genetic variation as individuals of a species with favourable characteristics are more likely to reproduce
Over time, a species in a certain environment changes due to the challenges they face
What is hybridization
The process by which two differnet species come together and reproduce to create a hybrid offspring
This can happen naturally when animals of different species mate
