1. Plants Characteristics: Multicellular Eukaryotic Photosynthetic
Cells have cell walls made of cellulose

2. 2 Categories of Plants:
Non-vascular:
Does not have true
stems, roots and leaves.
Does not have xylem and phloem
Vascular:
Have true stems, roots
and leaves.
Have xylem and phloem
(Vascular tissue)

3. Cell Types in Plants Parenchyma, collenchyma, and sclerenchyma
Functions:
Conduct photosynthesis
Stores starch, oils, and water for the plant.
Also important for healing wounds of the plant

4. Parenchyma
Details: Thin cell walls and large water-filled vacuoles in the middle. Most common type of cell in plants

5. Collenchyma Functions:
Provide support for the plant, while still allowing it to grow.
They are flexible.
EX: As a young leaf grows, collenchyma cells can elongate, giving the leaf structure.
Do not conduct photosynthesis.

6. Collenchyma
Details:
Most common in the younger tissues of leaves and shoots
Cell walls range from thick to thin.
Often form into strands. EX: celery strings
Cells walls do not contain lignin, so they are stretchy and can change size.

7. Comparing Parenchyma and Collenchyma

8. Sclerenchyma Functions:
Found in parts of the plant that are no longer growing.
Skeletal support for water-conducting tissues and the plant itself.
These cell fibers are used to make linen and rope.
Form a major part of fruit pits and hard outer shells of nuts.

9. Sclerenchyma Details: This is the strongest cell type of the three
Have a second cell wall that is hardened by lignin.
Makes the cells very tough, durable, and rigid.
These cells are not able to grow with the plant.
