Germination
The growth of a seed into a young plant or a seedling
germination
What is diffusion?
The movement of molecules from a region of high concentration to low concentration.
How does a plant get the energy that it needs?
It converts energy from sunlight into sugar in a process called photosynthesis.
Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen.
What happens to seeds when animals eat fruit?
The seeds get spread by the animals because it goes through their system.
In our seeds did plants require light to germinate?
No, they only need warmth, oxygen, and water
Where does a seed get its energy from?
Food supplies stored in a seed
How does water get into plant cells?
Water moves from the soil into the plants roots through osmosis. Osmosis is water moving from an area with more water to less water across a selectively permeable membrane, meaning it controls what will go in and out. The plants roots have less water than the soil.
What does a plant need to create energy/survive
Water
Carbon dioxide
light
Why does a plant produce fruit?
Fruit is the part of the flowering plant that contains the seeds.
What happened to the egg when it was in corn syrup? Why?
What are the 3 main parts of a seed?
embryo
food store
seed coat
What is the xylem?
Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.
Put these words into the photosynthesis "equation"
oxygen, sun light, glucose (sugar), carbon dioxide, water
______ + _______+_____ -------> ______ + ______
sun light + carbon dioxide+ water ----> glucose (sugar) and oxygen
What is Ms. Stark's favorite fruit?
Strawberries
Finish this sentence:
_______________________ entered the celery through _________________________ because
celery has a _____________________ concentration of water.
Water entered the celery through osmosis because celery has a lower concentration of water.
What 3 conditions does a plant need to grow?
water
warmth
air (oxygen)
What is the phloem in a plant?
Living cells that move nutrients through the cell.
Where does the process of creating energy take place?
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
True or False
Fruit is a reproductive organ of a plant?
True
What does the word "statolith" have to do with our seed lab? (Reading Response)
They are little round balls that have sensory receptors that respond to gravity, communicating which way the roots will grow.
How does a seed know to send its roots down and it's leaves up?
Seeds sense gravity and position accordingly to the gravitational pull. The statolith senses gravity.
What happens to water once it gets inside of a plant?
Once roots find the water, the water travels up to the leaves. The water travels through the xylem until it reaches mesophyll cells and they release the water through stomata.
Plants capture sunlight using a compound called ____________.
chlorophyll
Chlorophyll is green, which is why so many plants appear green.
What purpose does fruit provide for a plant?
Fruit protects the seeds and also helps spread them.
If something is selectively permeable what can move in and out and what can't?
Water can move in and out but sugars can't because they are larger.
