Plant Structures
The tiny pore on a leaf that allows gases to move in and out.
What is a stoma?
This tissue carries water upward from the roots.
What is xylem?
Growth toward light is called this.
What is positive phototropism?
Seeds allow plants to reproduce in dry environments because of this structure.
What is pollen carrying the male gametes?
Which plant system shows order by moving materials in opposite directions through specialized tubes?
What is the vascular system (xylem and phloem)?
This plant part develops into fruit after fertilization.
What is the flower (specifically the ovary)?
This tissue carries sugars made during photosynthesis.
What is phloem?
Root growth downward is called this (related to gravity)
What is positive gravitropism?
This type of plant blooms when nights become longer.
What is a short-day plant?
How does phototropism show purposeful design?
It helps plants reach light for photosynthesis and survival.
Growth rings in a tree trunk tell us this about the tree.
What is its age?
Why can’t moss grow tall like an oak tree?
It lacks vascular tissue for transport.
This hormone causes cells on one side of a stem to grow longer, making it bend.
What is auxin?
Name one advantage seeds have over spores.
They protect the embryo and store food.
Why is the seed structure an example of careful design?
It protects and nourishes the embryo.
This structure protects seeds in flowering plants but is not found in gymnosperms.
What is fruit?
If xylem stopped working, what would happen to the leaves?
They would not receive water and would wilt/die.
This hormone slows growth and helps plants respond to stress.
What is abscisic acid?
Why do seed plants not require standing water for fertilization?
Pollen transports sperm without needing water.
How do plant hormones demonstrate regulation and balance?
Different hormones promote or inhibit growth in coordinated ways.
Explain why cones and fruits are not the same structure.
Cones hold naked seeds; fruits enclose seeds and develop from flowers.
Explain how xylem and phloem work together to keep a plant alive.
Xylem moves water up; phloem moves sugars throughout the plant.
This hormone increases cell division but limits elongation.
What is cytokinin?
Pollen transports sperm without needing water.
Spores are single cells without stored food; seeds contain an embryo and food supply
A seedless vascular plant and a flowering plant both survive successfully in different environments.
Explain how their reproductive systems differ and how those differences demonstrate order and wisdom in God’s design.
Answer must include:
spores vs. seeds
vascular tissue
water requirement vs. pollen
at least one sentence explaining purposeful design
