The Leaf

media

Today we will identify the structures that make up a leaf and explain how they are used to conduct the process of photosynthesis

Dropdown

The xylem transports​
from the roots to the shoots.

The phloem transports​
from the leaf to other tissues in the plants.

2. Palisade Mesophyll cells have many chloroplast - found in upper part of the leaf

Leaf Structure

13

Chloroplast is the membrane-bound organelle that conducts the process of photosynthesis.

Chlorophyll is a green pigment - this is why plant cells are green!
