|
Name the 3 types of plant cells:
|
1. Parenchyma
2. Collenchyma 3. Sclerenchyma |
|
|
List the function of each type of plant cell.
|
1. Parenchyma - stores sap and food production.
2. Collenchyma - support. 3. Sclerenchyma - support. |
|
|
Name the two different types of vascular tissue, and what they each transport.
|
1. Xylem - transports water and dissolved minerals.
2. Phloem - tranports sugars (food). |
|
|
Explain the function of stomata:
|
This is where gas exchange happens (release of oxygen and take in carbon dioxide).
|
|
|
Name the four types of plant tissuue and their main function.
|
1. Dermal tissue - cover and protect plant.
2. Vascular tissue - transports materials. 3. Ground tissue - storage, photosynthesis, support (filler). 4. Meristems - new cell growth. |
|
|
What is the function of stems
|
supports plants, transports water and food.
|
|
|
What is the function of leaves
|
photosynthesis
|
|
|
What is the function of roots
|
anchor plant, absorb water and minerals
|
|
|
What is the function of root hairs
|
absorbs water (increases surface area of the roots)
|
|
|
What is the function of caps
|
protects new cell growth
|
|
|
Explain how guard cells function and regulate the size of a stoma
|
by opening and closing stoma they regulate water loss.
|
|
|
Draw a cross-section of a root and label the following:
|
root hair, epidermis, xylem, and phloem.
|
|
|
What is the translocation?
|
the movement of sugars in the phloem.
|
|
|
Explain transpiration:
|
the loss of water out the stoma which causes the movement of water up the xylem.
|
|
|
How do seeds enable plants to survive harsh conditions?
|
the seed coat protects them from drying out and protects the embryo and seed have stored food.
|
|
|
Explain why walnut flowers are considered incomplete flowers.
|
they do not have pistils meaning they do not have both female and male reproductive structures.
|
|
|
How does photoperiodism influence flowering?
|
Flowering is influenced by the number of hours of darknewss.
|
|
|
In the middle of summer a florist receives a shipment of short-day plants. What must the florist do to induce flowering? Why?
|
the florist should cover the greenhouse with a tarp each afternoon to shorten the day and length the night because flowering is controlled by the number of hours of darkness.
|
|
|
What is the difference between pollination and fertilization?
|
Pollination is the transfer of pollen to the pistil where fertilization is the fusion of the pollen grain and ovule.
|
|
|
Name the part of the anthophyte flower that becomes the fruit.
|
the ovary
|
|
|
Infer how the production of nectar could enhance the pollination of a flowering plant
|
nectar attracts animals, they get pollen on them as they try to reach the nectar when they travel from flower to flower they help with pollination.
|
|
|
Animals eat seeds such as peanuts, sunflower seeds, and almonds. Why are seeds a good food source?
|
Seeds are mostly stored food intended for use by the embryo.
|
|
|
Which flower parts make up the following structures: (circle the male structure)
|
Pistil - stigma, style, ovary
Stamen (male structure) anther, filament. |
|
|
What is dormancy? What factors have an effect on it?
|
a period of inactivity for a seed - water, oxygen and warm temperatures can effect dormancy.
|
|
|
Draw a flower and label the following: stigma, ovary, anther, style, filament, petals, sepal, pistil, stamen. Include the function of each.
