A
Plants have two specialized vascular tissues. Cite those two.
Xylem and Phloem
What parts of a plant does the xylem and phloem can be found?
STEM
Xylem carries _________ & ________ upward from roots to stem and out to the leaves.
Water & Dissolved mineral nutrients.
What is the direction of movement in xylem?
One-way upward
What is the direction of movement in phloem?
Two-way upward and downward
.What do you call this process where plants absorb water through the roots and then give off water vapor through pores in their leaves?
Transpiration
Xylem cells are _____ cells.
Dead cells.
Phloem carries ________ made during photosynthesis.
Glucose (sugar)
It moves food from the leaves down to the roots for storage, or up to growing buds, flowers, and fruits.
Phloem
It is the process of loading that sugar into the phloem’s sieve tubes and shipping it to wherever the plant needs it- down to the roots for storage, or up to growing flowers and fruit.
Translocation
It is a tiny, microscopic mouth (pores) found mostly on the underside of leaves.
Stomata
They open and close to let plant “breathe” in carbon dioxide and let out oxygen and water vapor.
Stomata
A pair of kidney-shaped cells that flank each stomata like security guards.
Guard Cells
they swell and curve open causing the stomata to open
What happen to the stomata when they lose water?
they go limp and close the doors to save water.
The tunnel system inside the phloem (the food highway). It looks like a long pipe made of living cells with tiny, strainer-like holes at the ends.
SIEVE TUBE
Are there any similarities and differences between human organ systems working together and plant parts working together? Why?
Yes, both humans and plants rely on interconnected parts to transport nutrients and survive, but humans use a centralized nervous system for rapid coordination while plants rely on decentralized chemical signaling for slower responses.
What is root pressure responsible for?
Pushing water from the roots to the leaves
What is capillary action?
The movement of water through narrow tubes
The ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
CAPILLARY ACTION
