Study Notes
Living Things
- Living things, also known as organisms, exhibit key characteristics: growth, reproduction, respiration, sensitivity, excretion, and nutrition.
- Growth involves increasing size or cell number.
- Reproduction creates new organisms like the parent.
- Respiration releases energy from food, consuming oxygen and releasing carbon dioxide.
- Sensitivity allows organisms to react to environmental changes.
- Excretion removes waste products.
- Nutrition obtains nutrients from food for energy and growth.
Plants
- Plants are autotrophs, making their own food through photosynthesis.
- Photosynthesis uses sunlight, water, and carbon dioxide to produce food and oxygen.
- Plant structures include roots, stems, leaves, flowers, and fruits.
- Roots absorb water and minerals.
- Stems support the plant and transport materials.
- Leaves are the primary sites of photosynthesis.
- Flowers facilitate reproduction.
- Fruits protect and disperse seeds.
- Plants are vital for Earth's oxygen supply.
Animals
- Animals, or heterotrophs, must consume other organisms for nutrition.
- Animals adapt for survival via feeding, movement, and protection strategies.
- Animal behaviors include seeking food, responding to threats, and caring for young.
- Animal groups include mammals, birds, reptiles, amphibians, and fish.
- Mammals are warm-blooded and nourish their young with milk.
- Birds have wings and feathers, laying eggs.
- Reptiles are cold-blooded with scaly skin.
- Amphibians live in both water and land.
- Fish live in water, breathing through gills.
Nutrition in Plants
- Plants make food through photosynthesis, using sunlight, water, carbon dioxide, and chlorophyll.
- Chlorophyll absorbs sunlight; a green pigment in leaves.
- Photosynthesis converts light energy into chemical energy stored in food.
- Oxygen is a vital byproduct of photosynthesis.
Nutrition in Animals
- Animals consume other organisms for nutrients.
- Animals exhibit various feeding strategies; herbivores eat plants, carnivores eat animals, and omnivores eat both.
- Digestive systems break down food for absorption and use.
- Digestive systems differ based on diet.
Respiration in Living Things
- Respiration releases energy from food using oxygen and releasing carbon dioxide.
- Respiration occurs in all living things, in plants and animals.
- Plants respire both day and night.
Importance of Photosynthesis
- Photosynthesis creates food for plants, releasing oxygen crucial for animals.
- Plants are primary producers in the food chain.
- Photosynthesis is essential for maintaining a balanced environment.
Excretion in Plants
- Plants remove waste through processes like releasing gases and dropping dead leaves.
Excretion in Animals
- Animals excrete waste products like urine, sweat, and carbon dioxide.
Sensitivity in Living Things
- Living organisms react to their surroundings using their senses.
- Plants and animals respond to stimuli like light, heat, and touch.
Comparing Living Things
- Comparing plants and animals highlights their distinctions and commonalities.
- Adaptations reflect differing needs in diverse environments.
Growth
- Plant growth continues throughout life, increasing leaves, stems, and roots.
- Animal growth is limited, with specific patterns per species.
Reproduction
- Living things reproduce to create similar organisms.
- Animal reproduction varies from laying eggs to live birth.
- Plants reproduce using flowers, leading to fruits and seeds.
Life Cycle
- A living thing's life cycle are the development stages from birth to death.
- Life cycles differ drastically among species.
- Plant and animal life cycles have distinctive stages.
