growth
all living things grow an increase in cell size or number, babies grow into adults,seedlings, plants grow towands the sun
respiration
plants and animals use oxygento turn food into energy. break down nutrients into small units and release chemical energy in their bonds.
regulation
all living things are sensitive, respond to changes-notice them and react to them(outise environment) Help control internal stimuli.ex.people react to temperature and plantsgrow towards the sun.
movement
animals move from one place to another. plants grow towards the sun and roots grow down into the soil.
reproduction
All living things reproduce.Animals have babies. New plants grow from seeds.
nutrition
Food is used to provide energy. Green plants make own food using sunlight. Organisms must obtain nutrients from environment Animals eat plants or other animals
excretion
waste substances must be removed. Plants and animals nee to get rid of wastes, gas, and water. cells excrete.
metabolism
all the chemical reactions occurring within the cells of an organism. constant release of energy. break down and build up of all reactions. know metabolic process and activities
homeostasis
matinence of constant internal conditions in a caotic world. keeping internal conditions constant such as temperature.
biosphere
portion of earth where life exists
biotic
living things
abiotic
non-living things
life processes
there are 7 that are needed to be alive.
cellulose
makes the cell wall in plants. our body can't digest it.
synthesis
making something. maintains homeostasis things are needed to be built up and broken down
viruses
exception to 7 life processes reproduce only when in your body and takes of dna and reproduces can be dangerous. when on a table it is harmless.
prokaryotic cells
unicellular organisms lacking nucleus smaller than eukaryotic cells living
eukaryotic cells
organisms whose cell contains nucleus, bigger than prokaryotic cells and more complex. living and animals are eukaryotic.
cell theory
All living things are composed of cells, cells are the basic unit of function and structure in a living thing, new cells are only produced from existing cells.
