What is living?
2 examples of nonliving things
rocks, tables
structure equals ______
function
Vacuole
stores extra water and nutrients
Define organism
living plant, animal, celled life form
Cells are made of
organelles
Example of how a living human maintains homeostasis
temperature: shivers when cold, sweats when hot
Planet cells need chloroplasts unlike animals because
they make food through photosynthesis from the sun
structure, protection
Abiotic environmental facotrs
nonliving elements in ecosystem like space, water, sunlight
Polar bear adaptation
white fur to blend in and survive in snow
fight: act big
flight: run away
Cells come from
existing cells
Mitochondria
power house, cellular respiration providing energy
Biotic environmental factors
living factors in ecosystem like predators, trees for oxygen
Examples of harmful environmental factors from humans
deforestation, overcrowding, pollution
3 characteristics that determine something is living
1. Made of cells
2. Can grow
3. Can reproduce and survive
Organelles plant cells have that animals cells don't
Cell wall - change shape and function
Chloroplasts - don't need to make own food (consumer not producer)
Nucleus
brain of cell, controls cell growth
Definition and example of an adaptation
cactus holding water, camouflage, fur, flying
Cell membrane function
filter - lets good nutrients in, removes bad waste
How do species evolve and survive
adaptation to environment and pass on best genes for survivial
Benefit for animal cells not to have a cell wall - example
Cytoplasm
jelly like, holds all organelles in place
Benefit of inheriting genetic factors
best ones suited for survival help adaptation and evolution
What organelle contains the cells DNA
nucleus
