Questão 16
Questão
The purpose of cork tissue is to [blank_start]protect[blank_end] and [blank_start]waterproof[blank_end] the stem.
Questão 17
Questão
The purpose of parenchyma tissue is to [blank_start]make[blank_end] and [blank_start]store[blank_end] food.
Questão 18
Questão
[blank_start]Xylem[blank_end] tissue transports [blank_start]water[blank_end] and dissolved minerals upwards to the leaves; [blank_start]Phloem[blank_end] transports [blank_start]food[blank_end] manufactured in the leaves downward to the rest of the plant.
Responda
-

-
food
-
xylem
-
phloem
-
food
-
water
Questão 19
Questão
The purpose of the leaf's epidermis is to [blank_start]cover[blank_end] and [blank_start]protect[blank_end] the leaf surfaces.
Questão 20
Questão
The purpose of vacuoles is to [blank_start]store[blank_end] food materials, fluid substances, and minerals.
Questão 21
Questão
This is the process of photosynthesis. The plant uses the energy of the [blank_start]sun[blank_end] to split the [blank_start]water[blank_end] molecules into hydrogen ions and oxygen. The hydrogen ions are combined with [blank_start]carbon dioxide[blank_end] from the air to form [blank_start]glucose[blank_end], a simple sugar.
Responda
-
sun
-
water
-
carbon dioxide
-
glucose
Questão 22
Questão
Choose the 4 factors that affect the rate of photosynthesis:
Responda
-
amount of water available
-
amount of hydrogen available
-
amount of carbon dioxide available
-
temperature
-
amount of nitrogen in the soil
-
intensity of light
Questão 23
Questão
What causes leaves to turn different colors in autumn?
Responda
-
The weather turns cold which dissolves the abscission layer and changes the chlorophyll to different colors.
-
When the abscission layer forms, the chlorophyll in the leaf begins to deteriorate, allowing other pigments that had previously been hidden by the chlorophyll to become visible.
-
In autumn, there is less sunlight, which causes the rainbow to appear in the leaves.
Questão 24
Questão
When the [blank_start]abscission[blank_end] layer forms, the [blank_start]chlorophyll[blank_end] in the leaf begins to deteriorate, allowing other pigments that had previously been [blank_start]hidden[blank_end] by the chlorophyll to become visible.
Responda
-
abscission
-
chlorophyll
-
hidden
Questão 25
Questão
How do guard cells help conserve water? When [blank_start]water[blank_end] is being lost faster than it can be replenished, the [blank_start]guard[blank_end] cells lose [blank_start]turgor[blank_end] pressure and close the [blank_start]stomata[blank_end]. This reduces the rate of [blank_start]transpiration[blank_end] and water loss.
Responda
-
water
-
guard
-
turgor
-
stomata
-
transpiration
Questão 26
Questão
Why is the concept of the "simple cell" not valid?
A single cell is like a tiny self-contained [blank_start]city[blank_end] with its own [blank_start]power[blank_end] plants, chemical factories, food [blank_start]warehouses[blank_end], [blank_start]waste[blank_end] disposal facilities, and [blank_start]transportation[blank_end] networks, all directed automatically by programs in the cell's [blank_start]control[blank_end] center.

city
-
power
-
warehouses
-
waste

control
Questão 27
Questão
Explain why a leaf would not function correctly without veins. Veins are needed to [blank_start]transport[blank_end] water and other nutrients to the leaf from the [blank_start]roots[blank_end] and to transport sugars produced in the [blank_start]leaf[blank_end] to the other parts of the plant.
