What does the flower part of a plant do?
It is responsible for reproduction.
100
What does phloem transport?
Food and sugar
100
Identify the two chemical inputs (reactants) a plant requires to carry out photosynthesis.
carbon dioxide and water
100
What does the stigma do?
It is the sticky landing for the insect or pollen.
100
What type of distribution do Cocklebur seeds covered in tiny hooked spines?
Animal fur
200
What does the leaf part of a plant
It is responsible for photosynthesis
200
How do root hairs help with plant growth?
Greatly increase the surface area in contact with soil particles. This increased area allows the plant to absorb maximum available moisture even when soil water is scarce.
200
Identify the gas released into the atmosphere as a byproduct of photosynthesis.
oxygen
200
Is X male or female part of the plant? (The Stigma)
The stigma is male.
200
What type of distrubution do Hollow, buoyant coconut husks that float
water
300
What does the stem part of the plant do?
It is responsible for support and transfers xylem and phloem.
300
Which structure on the underside of a leaf opens and closes to control gas exchange and water loss?
Stomata

Plants are classified as autotrophs (producers) in food webs. Explain what the term "producer" means in an ecosystem and identify the original source of energy for all producers.
A producer makes its own food, and gets its energy from the sun.
300
Explain what happens to Part Y (ovary) and the ovules inside after successful fertilization occurs.
The ovary develops into a fruit and fertilized ovules develop into seeds.

What type of distribution do sweet, fleshy blackberries with tough seed coats use?
Animal ingestion
400
What do roots do for a plant?
It anchors the plants and absorbs water and minerals.
400
When a celery stalk is placed in a beaker containing red-dyed water for 24 hours, the red color appears in the leaves. Explain what this observation proves about liquid movement in plant stems.
Water moves upward through the stem against gravity.

A 5th grade student claims that plants gain most of their physical weight (biomass) by absorbing soil particles through their roots. True or False
False
400
Which animal is considered a primary pollinator of brightly colored, sweet-scented daytime flowers?
honeybee

Cacti survive in arid desert environments where rainfall is scarce. Describe two specific structural adaptations that allow a cactus to survive extreme drought conditions.
Answers vary, but thick stems and thin spines instead of leaves to avoid losing moisture.
500
What does xylem transport?
Water
500
Name the green pigment found inside leaf cells that absorbs light energy from the sun.
Chlorophyll
500
water...chlorphyll...oxygen

What type of dispersal do lightweight dandelion seeds with feathery parachutes
wind

Water lilies live floating on the surface of freshwater ponds. Explain why their stomata are located on the upper surface of their leaves rather than on the underside.
The lower surface is submerged in water, preventing air exchange. Having stomata on the upper surface allows direct contact with air for taking in carbon dioxide and releasing oxygen.
