Germination and Plant Growth
By Claire and Tim
What is inside a seed when it dormant?
What happens when the seed absorbs water? Why do roots and shoots develop first?
As the water gets soaks into the plant the plant starts to swell or bloat the seed coat splits allowing the seed to germinate and grow.
In the growth of the roots and shoots the roots develop first in order to sustain the structure of the plant. It also helps brings up the necessary nutrients to help the plant growth. The shoots eventually turn into the leaves and stem of the plant and they are needed to get the energy-light from the plant.
Gardening Guaranteed to be relaxing!
Difference between monocot and dicot germination? Amount of time? Why?
Some of the differences are that monocots have leaf veins are parallel,Vascular bundles usually complexity arranged, Fibrous root system, and Floral parts usually in multiples of three. Dicots have veins usually netlike, vascular bundles usually arranged in ring, taproot usually present, and Floral parts usually in multiples of four or five. The differences between how there germinate is when monocots have one leaf which are small and thin and dicots have two seed leaves which are fat because they are full of the plants nutrients. It doesn’t take long with the right conditions.
Does the presence of light affect germination? How or Why?
Most plant it doesn’t matter if it is in darkness or light unless you are in a forest setting and in that setting the plant waits to grow until sunlight is let through the canopy. It all depends on the environment and the plant type if it needs light or not.
Why do some seeds not germinate at all?
Some reasons that they don’t germinate is because of them being planted too deep, no light, seeds drying out and there are a lot more reasons.
Why do some germinated seeds die when transplanted to soil?
They could dry out, not enough nutrients in the soil for them to grow, or Post-emergent damping-off.
What are the vital nutrients for seed germination?
There are 16 nutrient elements required to grow crops. There are 3 essential nutrients carbon (C),hydrogen (H) and oxygen (O2). Then 13 other nutrients known as Primary, Secondary, and Micronutrients. Some primaries are nitrogen (N), phosphorus (P) and potassium (K). THe secondary are calcium (Ca), magnesium (Mg) and sulfur (S). The Micronutrients are iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B) and molybdenum (Mo).
How does gravitropism affect germinated seeds?
The plants are under the soil and there roots have started to grow along with the shoots will soon grow. We have germinated them and then put them in the plant.
Corn and Beans
The Corn and beans are started to visually show and they have grown their shoots and they are starting to grow up towards the light.
The corn plant has been transferred into a bigger pot letting it grow more and letting the root system expand.
Corn and Beans
The beans are starting to grow and they also got put into a bigger pot so that their root system can grow.
The corn has started to grow towards the light.
The beans are starting to grow up and start to get leaves and it is still growing up. The plants are still growing up and dont have a big width.
The corn has started to grow up and is started to get flimsy but still growing towards the light.
Corn and Beans
The corn has started to bend and lean agains the edge of the pit and the beans are growing up ward and starting to lean. It has many leaves but not the biggest width.
These are adult Corn and Bean plants growing out side.
Corn and Beans
Are beans and Corn vascular or nonvascular, monocot or dicot, angiosperm or gymnosperm?
Corn is monocot.
Beans are Dicots.
Beans and corn are angiosperms.
The Description and the Function of Xylem and Phloem
The Function of the Phloem is transportation of food and nutrients such as sugar and amino acids from leaves to storage organs and growing parts of plant.
The structure of the xylem is a Tubular shape with no cross walls which allows a continuous column of water + facilitates more rapid transport within the xylem vessels.
The structure of the Phloem a Elongated, tubular shape with thin walled sieve tubes. The sieve tubes have pores at each end in the cross walls and microtubules that extend between sieve elements allowing longitudinal flow of material.
What type of roots do plants have?
Soil Nutrients test
To fix the the Nitrogen and Phosphorus being depleted we added plant food to our plants to hopefully fix that they were depleted.
Our plant is generally small in stem but our leaves are a medium size, our corn is tall and flimsy.
Nitrogen controls the plants height.
Phosphorus controls the plants photosynthesis. . It conversion of light energy to chemical energy
Plant Growth Rates
Plants response to Hormones
The plants are showing that the milk we have been putting on the once a day is helping by giving them more calcium. The two big plants we have are fighting to get to the sun because so they can produce more beans.
What we learned
We learned that if you have the right amount of moist and light you can have profitable amount of growth from your plants. Along with adding calcium it can make the plant grow faster by supplying it with a high amount of calcium.
