Plant structure and Photosynthesis Flashcards
1
Q
Name 3 plant organs
A
Stems, roots and leaves
2
Q
What are organs made of?
A
Tissues
3
Q
What are leaves made of (3)?
A
Mesophyll tissue (Where most of the photosynthesis occurs)
Xylem and Phloem (transport water, mineral ions and sucrose around the plant)
Epidermal tissue - covers the whole plant
4
Q
What is the equation for photosynthesis?
A
Carbon Dioxide + Water -> Glucose + Oxygen
-> [sunlight and chlorophyll needed]
5
Q
Where does photosynthesis happen?
A
In chloroplasts
6
Q
What do chloroplasts contain that allow photosynthesis to happen?
A
Chlorophyll
7
Q
What does chlorophyll do?
A
absorbs sunlight and uses its energy to convert CO2 and water into glucose. Oxygen is also produced as a by-product
8
Q
How does water reach cells?
A
Through the Xylem
9
Q
How does CO2 reach the cells?
A
It diffuses
