Plant System

Question 1

What is the main function of the shoot system?

Answer 1

System in flowering plants that is specialized to

• Conduct food and water
• Photosynthesize
• Reproduce sexually

Question 2

What is the main function of the root system?

Answer 2

system in a flowering plant, fern, or conifer that

• anchors the plant
• absorbs water and minerals through root hairs
• conducts water and nutrients
• stores food and nutrients

Question 3

What does the plant system consist of?

Answer 3

-leaf
-flower
-stem
-roots
They are all specialized cells

Question 4

What is dermal tissue system?

Answer 4

Tissues covering the outer surface of the plant

Question 5

What is vascular tissue system?

Answer 5

• All plant tissues responsible for conducting materials within the plant
• Like animal circulatory system

Question 6

What is the ground tissue system?

Answer 6

All plant tissues other than those that make up dermal and vascular tissue systems

Question 7

What is the function of the leaf in the shoot system?

Answer 7

• photosynthetic structure of the plant

- organelle called chloroplasts performs photosynthesis

Question 8

What is the function of the flower in the shoot system?

Answer 8

• pollination

- reproduction

Question 9

What is the function of the stem in the shoot system?

Answer 9

• supports branches, leaves, and flowers
• provides a way to transport materials
• vascular tissues is contained for carrying substances to and from roots, leaves, flowers, and fruits
• some are specialized for food storage, protection, photosynthesis and reproduction

Question 10

What is the palisade layer?

Answer 10

-tightly packed ground tissue below the leafs upper surface where the maximum light is

Question 11

What is the spongy mesophyll?

Answer 11

-Loosely packed ground tissue through the interior of the leaf

Question 12

What is the function of cuticle?

Answer 12

thin layer of wax on the outside of the leaf that keeps the leaf from drying out and prevents gases from entering the leaf by direct diffusion through surface cells

Question 13

What is the function of stomata?

Answer 13

Openings in the leaf surface that are surrounded and controlled by pairs of special epidermal guard cells

Question 14

What is the function of guard cells?

Answer 14

control opening of the stomata. Guard cells bend outward to open stomata, collapse inward to close stomata.

Question 15

Where are the stomata located and why?

Answer 15

Where are the stomata located and why?

Question 16

When would stomata open?

Answer 16

When it is sunny and there is lots of water in the leaf.

Question 17

When would the stomata close?

Answer 17

When it is dark (night) or if there is not enough water in the cell.

Question 18

How to guard cells open and close?

Answer 18

When there is lots of water guard cells expand and bend apart, which opens stomata. When there is not enough water guard cells become soft and collapse, closing stomata. The vacuole works the same way, when there is lots of water, the vacuole expands and keeps the cell plump but when there is not enough water the vacuole collapses and softens.

Question 19

How to plants obtain water?

Answer 19

Root hairs absorb water by osmosis and the water is then transported by the xylem from the roots up the stem and into the leaves
