Plants
Structure, Function, and Reproduction

2. Parts of a Plant Roots Anchor the plant Absorb water and nutrients
Storage of organic nutrients (sugar and starch)
May have one central root with branching roots
May have branching roots and no central root

3. Parts of a Plant
Stem – support the leaves and house the vascular tissue
Woody stem
Stiff and nongreen
Have buds on the ends
Think trees
Nonwoody stem
Flexible and green
Herbaceous plants – violets, clovers, and grasses

4. Parts of a Plant Vascular Tissue Xylem Phloem Goes up
Brings water and nutrients up from the roots
Phloem
Goes down
Bring sugar and other nutrients throughout the plant

5. Parts of a Plant Leaves Primary photosynthetic organ in a plant
Simple leaves
One blade
Compound leaves
Multiple blades

6. Leaves
 Single blade leaf
Multiple Blade Leaf 

7. Parts of a Plant
Remember that plants have a waxy coating around their roots and stem
This allows water to get in but harder for it to get out
Think of it as a protective coating

8. Function
All of these parts work together to give the plant nutrients and allow it to reproduce.
The roots and xylem bring up water and nutrients from the ground
The leaves and phloem allow the plant to perform photosynthesis and bring nutrients to other parts of the plant

9. Types of Plants
Nonvascular Plants – smaller size, larger gametophytes, and require water for sexual reproduction
Mosses
Liverworts
Hornworts

10. Types of Plants
Seedless vascular plants – vascular system, larger sporophyte, drought resistant spores
Ferns
Club mosses
Horsetails
Whisk ferns

11. Gymnosperms
Seed plants whose seeds do not develop within a sealed container (like a fruit)
These plants have cones and needles
The largest group of gymnosperms are Conifers (California Redwoods)

12. Gymnosperms cont’d
Sperm are carried on pollen and moved by the wind – not a lot of water and this makes fertilization possible even in times of a drought

13. Angiosperms Produce seeds that develop enclosed within a fruit
2 subgroups – monocots and dicots
3 main key features
Flowers
Fruits
endosperms

14. Angiosperms cont’d 3 main key features
Flowers – male and female gametophytes develop within flowers (makes pollination easier and more successful), strong scent attracts pollinators

15. Angiosperms cont’d 3 main key features
Fruits – promote seed dispersal (when an animal eats it and poops it out it is like instant fertilizer and relocation!)

16. Angiosperms cont’d 3 main key features
Endosperms – the angiosperm seeds have a supply of stored food. This allows the embryo to have nutrients regardless of the conditions

17. Monocot v Dicot
Monocots are flowering plants that only produce seeds with one seed leaf
Monocots have their vascular tissue bundled
Dicots are flowering plants that produce seeds with two seed leaves
Dicots have their vascular tissue arranged in a ring

18. What the heck is a seed leaf?
A seed leaf is the first leaf that “pops out” of the embryonic seed.
When you first see the leaves, these are the seed leaves
The leaves after this are called the true leaves

19. Examples
MONOCOT
DICOT

20. Reproduction NO MORE NOTES I HAVE THIS ALREADY IN A HANDOUT FOR YOU!!!
ALL TOGETHER YOU CAN ALL THANK ME……..….NOW
