Plant Structure, Growth, & Development

2. Increase surface area to bring in more water and minerals
Vertical Growth
Angiosperms
Horizontal growth
Photosynthesis
Increase surface area to bring in more water and minerals

3. Support, secondary cell wall & lignin, dead at maturity
Generally unspecialized, only primary cell wall, has large central vacuole to store water and give support
Support, secondary cell wall & lignin, dead at maturity
Dead at maturity (only the cell wall left), makes up xylem, only angiosperms have vessel elements
More rigid primary cell wall, no secondary cell wall, capable of elongation
Makes up phloem, sieve-tube have no organelles (like nucleus) so the companion cells are like their “life support”

4. Primary Tissue

5. Meristematic Tissue

6. Cross Sections Animation
Helpful animation; good for when labeling slides for lab too!
There is no audio for the animation, and it automatically moves through the animation by itself.

7. Secondary Growth
I tried to find the best animation I could because I know this can be a difficult concept to grasp without an animation (for me, at least)
ine_content/animations/secondary_growt h_v2.html
The video on the right is also another good animation, but it just focuses on the vascular cambium

8. Leaf Structure Guess what. More animations:
