Plant structure and photosynthesis Flashcards
Name 3 plant organs
- Stems
- Roots
- Leaves
Name the 4 tissues of plant leaves
- Mesophyll tissue
- Xylem
- Phloem
- Epidermal tissue
What, like animals cells, are plant cells also organised into?
Tissues and organs
Explain the role of the mesophyll tissue
Where most of the PHOTOSYNTHESIS in a plant occurs
Explain the role of the xylem and the phloem
They TRANSPORT things like:
Water
Mineral ions
Sucrose
around the plant
Explain the role of the epidermal tissue
What covers the whole plant.
Where gases diffuse into the leaf via the stomata
What does photosynthesis produce?
Glucose- plant ‘food’ (and oxygen as a by-product)
What part of a cell does photosynthesis happen in?
The chloroplasts
Chloroplasts contain what substance?
Chlorophyll
What does chlorophyll do?
It absorbs sunlight and uses its energy to convert carbon dioxide (from the air) and water (from the soil) into GLUCOSE
Oxygen is also produced as a by-product
What is the main purpose of a plant’s leaves?
Photosynthesis
Complete the sentence:
Photosynthesis happens in the ______ of all _______.
Photosynthesis happens in the leaves of all green plants.
What is the word equation for photosynthesis?
sunlight
Carbon dioxide + water ———–> glucose + oxygen
chlorophyl
Which transports water to the leaves via transpiration: the xylem or the phloem?
The xylem
