Grow Baby Grow!
In what direction does primary growth take place?
Vertically
I aid in primary growth and cell differentiation from the top of the stem
Shoot Apical Meristem
Im the outer layer of the leaf that prevents water loss
cuticle
The ability for cells to gain a specific "job"
Cell Differentiation
Evolutionary advantage to why trees grow so tall
sunlight competition
What type of growth allows trees to grow so tall without falling over?
Secondary Growth
Im the point between the stem and a new meristem growth of a branch
node
I allow for long distance transport and involve the xylem and phloem
Vascular Tissue
While water transport is important, what is a big contributing factor that xylem brings by being dead
Strengthens structure
Can range in size depending on wet and dry seasons
tree rings
This term refers to a plant that starts it's growth with two leaflets
Dicot
I contribute to primary growth, but near the bottom of roots
Root Apical Meristem
I surround the Xylem and phloem to keep them together
Bundle sheath cells
I have airspaces around me to allow for gas exchange
Spongy mesophyll
Season that causes small, dark rings in trees
Cold and dry
Replaces the epidermis during secondary growth
Cork Cambium
I'm the thing that joins the leaves to their stems
petioles
I am found in mesophyll cells and allow for photosynthesis
chlorophyl
Cells often seen in celery that have thick cell walls and provide lots of support
collenchyma
The name for the very center part of the tree that tends to be very dark in color
Pith
This type of plant will not generally partake in secondary growth
monocot
I'm what takes in water and nutrients from the soil and allow for expanded surface area
root hairs
I'm the reason that the leaf is still able to participate in gas exchange, but am a reason for water loss
stomata
cells of the Xylem that have thick cell walls and become dead at maturity
Sclerenchyma
is the biggest drive in movement of water from the bottom of a tree to the top
Water Potential
