Plant Growth-Summative Flashcards
What are all seeds protected by?
A seed coat
What is a seed?
A seed is an embryonic plant enclosed in a protective outer covering along with some stored food, a flowering plant’s unit of reproduction.
What 3 things will you find inside a seed? (describe)
-Embryo, or baby plant -Endosperm, which is food storing tissue -Cotyledons, which absorbs nutrients for the growing plant
What does it mean when a seed is in dormant stage?
They are in a resting phase, not using much energy, low metabolic activity; Appear to be inactive to the eye.
What does germination mean?
The growth of a plant from the seed stage to the adult stage when it can produce new seeds.
What two things will make the seed begin to grow?
-An adequate amount of water/hydration (makes the seed swell) -A warm temperature
What is the food plants produce called? How do they produce this?
-Glucose -Going through photosynthesis
What does food provide for the plants?
Energy
Along with the glucose plants produce, what other 5 things do plants need in order to grow?
Light, air, water, a suitable temperature, and minerals.
What do plants need to grow healthy?
Nutrients/minerals
1.__________ replaces minerals to soil that has been depleted so plants can grow healthy. Why is this not food? 2.__________________________
- Fertilizer 2. it does not provide energy
How many minerals are needed for plant growth?
13
What are the main benefits of the following nutrients: Nitrogen, Phosphorous, Potassium
-Nitrogen: Promotes the growth of healthy leaves. -Phosphorous: Promotes strong, healthy roots, and helps flowers bloom. -Potassium: Helps plants withstand dramatic temperature changes and protects them from disease.
What are the other 10 nutrients known as?
Micronuutrients, or trace elements
Refer to Monocot and Dicot Study Guide on Brainscape for these questions.
Rate yourself on how you did…
Name examples of Monocots: (list at least 3)
Cereal grains, rice, corn, wheat, rye, grasses
Name examples of Dicots: (list at least 3)
Beans, peanuts, peas, apples, broccoli, most shrubs and trees, and almost anything grown in a garden
Define life cycle:
The coarse of development from birth to the stage when it can reproduce (from seed to adult plant that makes seeds)
What process did Dr. Williams use to shorten the life cycle of the Wisconsin Fast Plant?
Selective Breeding
In what ways, other than length of life cycle, did Dr. Williams alter the Wisconsin Fast Plant?
He made them shorter, with thicker stems, able to thrive in small places with other plants, and produce higher than average amount of seeds.
Why did he have the goals of ways to alter the Wisconsin Fast Plant?
He wanted to change these qualities so that they could thrive in a lab and be used to study plants in classrooms; As well as to grow food for large populations.
How can you prove that the Wisconsin Fast Plant is dicot?
There were two cotyledons that emerged out of the soil, and the vein patterns on the leaves look like crumpled paper.
