When an organism uses nutrients for energy and produces waste products, the organism is ________________
dormant
dead
metabolizing
living
All living organisms are made up of _________.
fiber
cells
skin
fungus
What does yeast need to break its dormancy?
warm water and sugar
warm water and flour
only warm water
only flour
Chlorophyll reflects ______ light.
blue
red
green
yellow
Wheat grass can grow in dark and light environments. Those grown in the dark are yellow and those grown in the light are green. Why?
The ones grown in light are pretty
The ones in the dark contain photosynthesis
The cells in photosynthesis contain carbon dioxide.
The cells in the green plants have activated the chlorophyll but the cells in the yellow have not.
Where do humans absorb the nutrients they need to provide energy for their body?
Stomach
Large Intestine
Small Intestine
Mouth
What inside of animals and humans is needed to help start the process of digestion?
Swallowing
Saliva
Hydrochloric Acid
Blood
What materials are needed in order for a plant to grow from a seed?
Sunlight
Water
Nutrients in soil
Oxygen
Carbon dioxide
When yeast becomes active, what gas is released as waste?
nitrogen
oxygen
carbon dioxide
water vapor
What is photosynthesis?
The process of using water and sunlight to make carbon dioxide
The process of turning oxygen and sunlight into sugar
the process that plants use to make sugar for growth
What makes a plant green?
chlorophyll
chloroplast
phloem
xylem
Where does the digestive system begin?
in your mouth
in your stomach
in your small intestines
in your esophagus
What is the main function of a plant's leaf?
Absorb water
convert light energy into glucose through photosynthesis
collect oxygen to create nutrients for the plant
a molecule that absorbs red and blue light and reflects green light
chloroplast
photosynthesis
chlorophyll
roots
a single-celled fungus
yeast
plants
animals
mushrooms
Where does all energy in an ecosystem come from?
plants
animals
Sun
If a plant is kept in the dark, but it is regularly watered, what will happen?
It will turn green and grow
It will turn yellow and grow
It will turn yellow and not grow
It will turn green and not grow
How do animals get the nutrients they need?
The digestive system breaks down food to nutrients. In humans, food enters the mouth, then down the esophagus to the stomach and small intestines.
They absorb sunlight, oxygen, and water to create nutrients cells need
They get nutrients in the water they drink
the basic unit of life
photosynthesis
carbon-dioxide
cell
oxygen
the nutrient that cells use for energy
carbon-dioxide
oxygen
sugar
nitrogen
Select the items that plants need in order to produce food.
sugar
water
oxygen
carbon dioxide
light energy
Select all that are products of Photosynthesis.
Chlorophyll
Carbon Dioxide
Oxygen
Sunlight (Light Energy)
Glucose (Sugar/food)
How does most of the water needed by the plant get into its leaves?
It enters through the stomata
The roots absorb it and then it travels up the stem
It's made during a chemical reaction in the leaf
The flowers capture water and deliver it to the leaves
Pick the correct order of digestion
Mouth,stomach,esophagus,large intestine,small intestine
Mouth,esophagus,stomach,small intestine, large intestine
Mouth, esophagus, stomach, large intestine, small intestine, colon
