Plants/Germination Flashcards
protective outer coat of a seed
seed coat
seed coats job
to protect the interior of the seed
the part of the seed that acts as a food storage for the developing plant embryo
endosperm
endosperm’s job
food storage
consists of percarsortissues for leaves, stems, and roots
embryo
embryo’s job
to house the developing part of the seed
development of a seed to a plant
germination
three main things for seed germination
water, temperature, and oxygen
When a seed is exposed to the proper conditions, ______ and _______ are taken in through the seedcoat.
water and oxygen
The _____ cells start to enlarge once water and oxygen are taken in through the seedcoat
embryo’s
Once the embyro’s cells enlarge, the _____ breaks open and the ________ emerges first, followed by the _______
coat, radicale, plumule
contains the leaves and the stem
plumule
the prefix photo means
light
the prefix auto means
self
the suffix troph means
obtaining food in a certain way
organisims that carry out photosynthesis
photoautotroph
difference between heterotroph and photoautotrophs
Heterotophs rely on other organisms to get food and photoautotrophs produce their own food
example of a heterotroph
animals
keeps leaves in light, provides support, transports liquids and sugars from roots
stem
absorbs and stores water and nutrients, anchors plants
roots
reproduction, petals
flower
converts energy from the sun to food, photosynthesis and gas exchange occurs here, conects stem to pedal
leaves
4 main things plants need to survive
light, air , water, nutrients
3 reasons why plants are important
- we create food from the energy and makes food for food chains
- produces oxygen
- provides resources
Plants are what type of cellular
multi-cellular
photosynthesis occurs where
chloroplasts
photosynthesis chemical equation
CO2+H2O–>C6H12O6+O2
3 ways plants spreed their seed
animals, wind, water
