Soils
What are the 3 main soil types?
Sand, Silt, and Clay.
What part of a plant absorbs water from the soil?
The roots.
What is plant propagation?
It is the process of making new plants.
The process plants use to make food using sunlight.
What is water cycle?
The movement of water through earth and the atmosphere.
Why do plants need soil?
For water and nutrients
What is a job of a plants leaves?
To make food through photosynthesis.
What is sexual propagation in plants?
Growing plants from seeds.
What are the main things plants need for photosynthesis?
Sunlight, water, and carbon dioxide.
What is evaporation?
When water turns into vapor and rises into the air.
Which soil drains water the fastest?
Sandy Soil
What tissue carries water through a plant?
Xylem.
What is a common type of asexual propagation?
Cuttings
Where does photosynthesis take place in a plant cell?
In the chloroplasts.
They release water vapor through transpiration.
What do nutrients do for plants?
Help them grow.
What is the function of the stem?
It supports the plant and moves water and nutrients.
Why do growers use asexual propagation instead of seeds sometimes?
It makes exact copies of the parent plant.
What gas do plants take in and release during photosynthesis?
They take in carbon dioxide and release oxygen.
What is the difference between condensation and precipitation?
Condensation is water vapor forming clouds; precipitation is water falling as rain or snow.
Why is compost added to soil?
To make soil healthier.
Why are stomata important to plants?
They allow gases like carbon dioxide and oxygen to move in and out of the plant.
What conditions help cuttings grow roots successfully?
Moisture, warmth, and proper soil or rooting medium.
Why is photosynthesis important for nearly all life on Earth?
It produces oxygen and is the base of most food chains.
How does the water cycle help plants grow and survive?
It provides fresh water through rainfall and keeps water moving though ecosystems.
