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.
