Which plant species also photosynthesises but has no real leaves?
Cacti (their stem is green) Roses Tulips Oak
Why do plants grow better in a greenhouse?
Because there is more light and warmth Because there is no oxygen Because there is no water As more carbon dioxide is removed

Watering and lighting plants Putting plants in the dark Not watering plants Giving plants a cold
What shape do leaves usually have in order to photosynthesise properly?
Flat and wide to catch a lot of sunlight Round and thick to hold water Long and thin to blow in the wind The shape does not matter
What is the difference between photosynthesis and respiration in plants?
Photosynthesis creates glucose, respiration consumes it Photosynthesis occurs at night, respiration during the day Photosynthesis uses oxygen, respiration carbon dioxide There is no difference
