1. Plant Cells, Tissue, and Organs

2. Plant Cells Unique Organelles: Cell Wall Large Water Vacuole
Chloroplast
-contain thylakoids
(discs) in stacks
known as grana

3. Dermal Tissue Features: Epidermis single layer of closely packed cells
covers and protects the plant
covered with waxy layer called a cuticle

4. Dermal Tissue Openings in epidermis known as stoma (pl. stomata)
Guard cells surrounding Stomata
Some tissue could have hair like structures

5. Dermal Tissue Function :
protects the plant from pathogens like viruses and bacteria
prevents excessive water loss
Provides an exchange of gases and material between inside and outside of plant
provides insulation for the plant

6. Vascular Tissue Features: Made up of xylem and phloem
At times found in Vascular Bundles

7. Vascular Tissue Function: Plants transportation tissue.
-Phloem transports sugar made during photosynthesis
-Xylem transports water and minerals

8. Ground Tissue Features: -can undergo photosynthesis (have chloroplast)
-have empty space between them
-have a large vacuole
-usually found close to dermal tissue

9. Ground Tissue
-thick cell walls
-some cells are dead
-support cells

10. Ground Tissue Function: leaves: where photosynthesis occurs
stem: provides strength and support
roots: store food and water

11. Meristemic Tissue: Undifferentiated Cells
Features:
-unspecialized tissue (stem cells)
- cells undergoing mitosis
-found at root and stem ends

12. Meristemic Tissue: Undifferentiated Cells
Responsible
for growing new parts of plant

13. Organs
An organ consists of different types of tissues that work together to perform one or more biological functions.
Plants have organs too!…kind of.
Plant “organs” will contain the different types of tissue but in different proportions.

15. Roots
Tissue:
-Mostly ground tissue with a centre of vascular tissue

16. Roots Function: - anchors the plant
- absorbs water & minerals from the soil
- stores food

17. Leaf

18. Leaf
Tissue:
-ground tissue is in the mesophyll (area between the epidermis where photosynthesis occurs)
-vascular tissue is in vein (contain vascular bundles) in mesophyll
-guard cells allow gases to move in/out

19. Leaf
Function:
- mostly the organ in charge of photosynthesis (to produce glucose)
- organ where most gas exchange occurs (needs to take in CO2 or release O2 and water vapour)

20. Stem

21. Stem
Xylem vessels and phloem vessles help transport materials…

22. Stem
Tissue:
- mostly ground (pith and cortex) and vascular tissue (pipes)
Function:
-supports plant
- Transportation of sap

23. Flower Reproductive organ of plant
Ovary produces ovule (similar to egg cell)
Anther produces pollen (similar to sperm cell)

24. Flower
Stigma catches pollen from other flower (cross-pollination) or its own flower (self-pollination) and carries it down style to fertilize ovule
This is how a seed is produced
-sometimes the flower produces fruit to house the seeds!

25. Flower Pollination Occurs because of wind or animals (birds/bees)
Animals visit other plants and transfer pollen
