E N D
Vocabulary • Autotroph (Producer) – Organism that makes it’s own food by using the Sun’s energy through photosynthesis • Cells – basic building blocks of living things • Competition – when organisms fight over limited (not enough) resources (food, water and oxygen) • Heterotroph (Consumer) – can not make their own food, they must eat for energy • Homeostasis (Regulation) – maintaining a stable internal environment and temperature
Vocabulary • Metabolism – all the chemical reactions (building and breaking down) that occur in an organism • Photosynthesis – the process of making food (glucose) by using the Sun’s energy, water and carbon dioxide • Reproduction – producing offspring (new individuals) • Response – a reaction to a stimulus • Stimulus – a change in the environment that causes a response
Characteristics of Living Things Unicellular 1. Cells • _______________________ - organisms that are made up of only one cell ex. Bacteria and Protists • _______________________ - organisms that are made up of more than one cell ex. Plants and Animals Multicellular
Characteristics of Living Things 2. Locomotion • Can ___________ Move
Characteristics of Living Things 3. Metabolism • All chemical reactions that occur in an organism • Ingestion – taking _____ food (eating) • Digestion - __________________ food into useable nutrients in breakdown
Characteristics of Living Things • Respiration – nutrients (food) combine with _______________ to produce energy and carbon dioxide • Excretion – getting rid of ____________ (solid, liquid, or gas CO2) oxygen wastes
Characteristics of Living Things 4. Growth • Increase in size and complexity • Multicellular cells ___________ for growth and repair divide
Characteristics of Living Things 5. Respond to the Environment • Stimulus – a ___________ in the environment that causes a response ex. Cold • Response – a ____________ to a stimulus ex. shiver change reaction
Characteristics of Living Things 6. Reproduce • Produce new _______________________________ • Needed for survival of a ______________ individuals (offspring) species
Characteristics of Living Things one • Asexual Reproduction • Requires __________ parent • Offspring are physically and genetically _______________ to the parent • Examples: • Unicellular organisms dividing (Mitosis) • Plant Clippings • Regeneration • Budding • Cloning identical
Characteristics of Living Things two • Sexual Reproduction • Requires __________ parents • Offspring are ______ physically and genetically identical to the parent • They have a _____________ of traits (_____________________) • Causes _______________ among organisms • Examples: • Joining of a sperm (___________) and an egg (______________) cell - fertilization • Joining of pollen (__________) and an egg cell not blending characteristics variety male female male
Needs of Living Things 1. Energy • Autotrophs (_________________) • Make their own food using the Sun’s energy by _____________________ • Example: __________ Producers Photosynthesis Plants
Needs of Living Things Consumers • Heterotrophs (_________________) • __________ make their own food • They must _________ for energy • Example: _______________ • Herbivore – eats only ___________ • Carnivore – eats only ______________ • Omnivore eats ________ plants and animals Can’t eat Animals plants animals both
Needs of Living Things 2. Water • Needed for chemical reactions to take place • Dissolves substances for _______________ transport
Needs of Living Things 3. Oxygen • Needed for aerobic respiration (combining __________ with food to produce energy • Most atmospheric oxygen comes from plants undergoing ____________________ oxygen photosynthesis
Needs of Living Things 4. Living Space • Enough area is needed for organisms to obtain _______________ (food, water, and oxygen) • Competition – when organisms ________ over limited (________________) resources causing those with the best traits to _____________ resources fight not enough survive
Needs of Living Things Regulation 5. Homeostasis (______________) • Maintaining a proper body temperature • Warmblooded – body temperature ___________________ despite the environment • Coldblooded – body temperature ____________ with the environment stays the same changes
6th Grade Review Material:Energy Transformation • Energy moving from one object to another • Heat from the Sun is transferred/absorbed by a pool causing the water to evaporate • After swimming your bathing suit absorbs heat from the Sun causing the water to evaporate and your suit to dry • The Sun's heat is received by the Earth by radiation (heat transferred through empty space)
