Which molecule directly provides usable energy for cell activities?
ATP
Which plant structure absorbs most water and minerals from soil?
Root
Which part of a plant is mainly responsible for photosynthesis?
Leaf
Which gas do plants take in during photosynthesis?
Carbon dioxide
Which cell structure captures sunlight to make food?
Chloroplast
Which organelle produces most of a cell's ATP during aerobic respiration?
Mitochondrion
Which plant tissue acts like a protective outer covering?
Dermal
What is the main job of a flower's colorful petals?
Attract pollinators
Which gas do animal cells use for aerobic respiration?
Oxygen
Which two substances are produced during photosynthesis?
Glucose and oxygen
What two substances are used in aerobic cellular respiration?
Oxygen and glucose
Which tissue transports water and dissolved minerals from the roots upward?
Xylem
Why do some desert plants close their stomata during the hottest part of the day?
To reduce water loss
How are photosynthesis and cellular respiration connected?
The products of one can be reactants of the other
A plant is placed in a sealed container with extra carbon dioxide and enough light and water. Which gas would it release during photosynthesis?
Oxygen
A runner's muscles use glucose to produce ATP. Which process makes this possible?
Cellular respiration
A plant makes sugar in its leaves. Which tissue moves the sugar to other parts of the plant?
Phloem
A plant has fewer available water molecules during a drought. Which process may decrease because water is needed?
Photosynthesis
A closed ecosystem needs organisms that remove carbon dioxide and release oxygen. Which would help most?
Photosynthetic algae
Why do rainforest plants growing in deep shade often have large leaves?
To capture more sunlight
Which process requires oxygen and would be affected if oxygen were unavailable?
Aerobic respiration
If a plant's vascular tissue is severely damaged, what is the most likely result?
It struggles to transport water and nutrients
A plant's roots are damaged during a drought. Which problem is most likely?
Reduced water absorption
Which statement correctly compares the two processes?
Photosynthesis stores energy in glucose; respiration transfers energy from glucose to ATP
