What are the shared characteristics of plants and animals?
Use energy for daily functions, compose many basic units of life, can reproduce and develop, respond to the environment
Define autotroph.
Organism that makes their own food
Define heterotroph.
Organism that cannot make their own food
What type of growth do most plants exhibit?
Indeterminate growth
What type of growth do most animals exhibit?
Determinate growth
What are the two types of reproduction?
- Asexual
- Sexual
What is asexual reproduction?
Does not involve the union of gametes, produces offspring identical to the parent, involves mitotic division
What is sexual reproduction?
Requires the union of gametes, involves two parents, produces diverse offspring
How do most animals develop compared to plants?
Animals take longer to develop than plants
What is the process of fertilization in sexual reproduction?
Sperm + Egg = Zygote → Embryo
What is sexual selection?
Species with certain characteristics are more likely to find a mate and reproduce
What is pollination?
The process of transferring pollen to another angiosperm
What are the three main processes of animal nutrition?
- Ingestion
- Digestion
- Absorption
What is ingestion?
The process of taking in food
What is digestion?
Breaking down food
What is absorption?
Absorption of molecules needed in the intestines
What are the two types of digestion?
- Intracellular Digestion
- Extracellular Digestion

What is holzoic nutrition?
Organisms ingest solid or liquid food
What is the difference between saprophytic and saprotrophic?
Both obtain nutrients from dead organic matter
