What are the 6 main parts of a plant?
seed, roots, stem, leaf (leaves), flower, fruit
100
In what step of the life cycle, does the seed opens and a tiny plant comes out?
sprout
100
What is the process called when plants make their own food?
photosynthesis
100
What is a place where living things (plants and animals) and nonliving things (water, rocks, air, etc.) live together?
ecosystem
100
What are 2 natural threats to ecosystems?
drought
wildfires
200
What part of the plant absorbs water and nutrients?
roots
200
What plant parts does a seedling have?
The seedling has roots, a stem, and leaves.
200
What do plants absorb during photosynthesis?
Plants absorb...
water (and nutrients from the soil)
sunlight
carbon dioxide
200
Name 3 ecosystems in the world.
Forests, Oceans, Deserts, Tundras, Grasslands, and Wetlands
200
What are 3 human threats to ecosystems?
deforestation
pollution
global warming
300
What part of the plant transports water and nutrients from the roots to the rest of the plant?
stem
300
When a plant reaches the plant stage, what do the roots absorb from the soil?
The roots absorb water and nutrients from the soil.
300
What do plants produce during photosynthesis?
Plants produce...
oxygen
glucose (sugar)
300
Why are plants important to wetland ecosystems? List 2.
Plants help clean the water and remove pollutants.
Plants provide habitat and food for many birds, fish, and insects.
300
What causes global warming (when the Earth gets hotter)?
Global warming is caused by humans putting too much carbon dioxide in the air.
Carbon dioxide is a gas that comes from cars, factories, and burning fossil fuels.
400
What part of the plant performs photosynthesis (makes food for the plant)?
leaf / leaves
400
Why are flowers important?
Flowers are important because they help the plant make seeds.
Flower attract pollinators.
400
Why do plants need photosynthesis?
to grow
400
Why are plants important to the ocean ecosystems? List 2.
Plants provide food and habitat for many sea animals.
Plants produce oxygen.
Plants help clean the water by absorbing carbon dioxide.
400
What are 2 effects of natural/human threats to ecosystems?
Animals and plants lose habitat;
Increase of carbon dioxide = global warming;
Reduced food
500
What part of the plant protects the seeds?
fruit
500
What is inside a plant's fruit?
seeds
500
Why are plants green?
Plant cells contain structures called chloroplasts, which are filled with a green pigment called chlorophyll. Chlorophyll is what makes green plants green.
500
Why are plants important to the forest ecosystems? List 3.
Tree roots help keep the soil in place and prevent erosion (the movement of soil and rock by water).
The leaves of trees absorb sunlight and carbon dioxide to make food.
Forests provide a habitat for many animals.
The plants in forests produce oxygen, which is essential for animals and humans.
500
What can humans do to protect ecosystems?
Reduce pollution (recycle plastics & walk/bike)
Plant trees
