Study Notes
Plant Responses to Environmental Conditions
- Plants react to stimuli in their environment, a process called tropism.
- A stimulus is anything that causes a change in an organism.
- Plants respond to stimuli through plant movement.
- Auxins are plant hormones responsible for various tropisms.
Plant Tropisms
- Phototropism: Plant response to light.
- Hydrotropism: Plant response to water.
- Geotropism: Plant response to the Earth's gravity.
- Thigmotropism: Plant response to touch.
- Anemotropism: Plant response to air.
- Thermotropism: Plant response to temperature.
- Heliotropism: Plant response to sunlight.
The Life Cycle of Humans
- A life cycle is how living things grow and change throughout their lives.
- It includes reproduction.
Infancy Stage
- Immediately after birth, babies depend on their mother's milk for nourishment.
Toddler Stage
- Toddler years are also called preschool years.
- Physical and motor development begins to slow down, though intellectual, emotional, and social development continues.
- Vocabulary and understanding concepts like time and opposites develop.
Childhood Stage
- This period is characterized by variability in growth rates among children.
- Children typically start school during this stage.
Adolescence/Puberty
- A period of rapid physical and emotional changes, typically occurring between ages 12-15.
- The changes occurring during this stage are typical and normal for both boys and girls.
Adulthood
- The adult stage is considered to begin after age 21.
- During this stage, humans generally have full physical and intellectual capacities.
Late Adulthood
- This begins at around 60 years old and is often associated with decreased physical and mental abilities in some individuals.
Stages in Animal Lifecycles
- Some animals are born alive from the mother.
Parts of a Seed
- Embryo: The part of the seed that will grow into a new plant.
- Endosperm: A food storage part for the developing embryo.
- Seed Coat: The outer protective layer of a seed.
Seed Germination
- Seeds need proper moisture, air, and temperature to germinate.
- The process typically begins with the embryonic root emerging first, followed by the stem.
Ecosystem Components
- An ecosystem includes living (biotic) and non-living (abiotic) things in an area.
- Biotic factors are life forms in an area.
- Abiotic factors are non-living things like sunlight, water, air, minerals, and temperature.
- Producers, consumers, and decomposers are living components.
Producers
- They make their own food through photosynthesis (plants).
Consumers
- They cannot produce food and rely on other organisms (producers or other consumers) for their food.
- Herbivores: Eat plants
- Carnivores: Eat meat
- Omnivores: Eat both plants and animals
Decomposers
- They break down dead organisms, returning nutrients to the ecosystem.
Food Chains and Food Webs
- Food chains are linear sequences showing how energy is transferred through organisms in the ecosystem.
- Food webs are interconnected food chains.
Beneficial and Harmful Interactions
- Symbiosis describes interactions between organisms living closely together.
- Mutualism: Both organisms benefit.
- Commensalism: One benefits, the other is unaffected.
- Competition: Organisms compete for resources.
- Parasitism: One benefits, the other is harmed.
- Predation: Consumers hunt and kill other organisms for food.
- Victims are called prey.
