• Transports water, sugars and minerals to different parts of the plant.

Question 6

What is the vascular tissue’s function in the shoot system?

Answer 6

• Transports materials through the plant.

Question 7

Root hairs location and function:

Answer 7

• Extension of a dermal cell on a plant root.
• Responsible for the absorption of water and minerals.
• Increase the area for the absorption of water.

Question 8

Cuticle location and function:

Answer 8

• On the surface of the leaf
• Protects the surface of the leaf and prevents water loss.

Question 9

Guard location and function:

Answer 9

• Located in the dermal tissue on the underside of the leaf.
• Forms pores called stomata to control gas exchange.

Question 10

Stomata location and function:

Answer 10

• Tiny openings on the dermal tissue.
• Controls gas exchange because of the openings in it.

Question 11

Chloroplast location and function:

Answer 11

• Located on the leaf mesophyll.
• Creates the green color which sites for photosynthesis.

Question 12

Palisade mesophyll location and function:

Answer 12

• Found below the dermal tissue.
• Responsible for photosynthesis.

Question 13

Spongy mesophyll location and function:

Answer 13

• Found below the palisade mesophyll.
• Controls gas exchange through diffusion.

Question 14

Xylem tissue location and function:

Answer 14

• Found in the upper part in the vein.
• Moves water and minerals from the roots to the leaves.

Question 15

Phloem tissue location and function:

Answer 15

• Found in the lower part of the vein.
• Transports food from the leaves to the rest of the plant.

Question 16

Which organelles are involved for photosynthesis?

Answer 16

• The cholorplasts

Question 17

What does photosynthesis need?

Answer 17

• Sunlight
• Water
• Carbon Dioxide

Question 18

What does photosynthesis produce?

Answer 18

• Creates oxygen and glucose

Question 19

Does photosynthesis take place in plant cells or animal cells?

Answer 19

• Takes place in plant cells

Question 20

Which organelles are involved in cellular respiration?

Answer 20

• First starts in the cytoplasm then in the mitochondria.

Question 21

What does cellular respiration need?

Answer 21

• Glucose
• Oxygen

Question 22

What does cellular respiration produce?

Answer 22

• CO2
• Energy
• Water

Question 23

Does cellular respiration take place in plant cells or animal cells?

Answer 23

Takes place in both plant cells and animal cells.

Question 24

What is tropism?

Answer 24

How it reacts to an external stimulus.

Question 25

What are 2 tropisms that affect plant growth?

Answer 25

Phototropism- A plant's response to light. It's when the plant bends towards the light source so it gets light for photosynthesis. Thigmotropisme- A plant's response to touch. This helps the plant to position itself to keep growing because some types of plants don’t usually have a strong stem to keep them up.

Question 26

Explain how transportation occurs in plants:

Answer 26

In plants, water enters the roots by osmosis because it is the diffusion (movement) of water. The water then leaves the root because of root pressure and transpiration pull then it goes through the xylem vessels so that the water then gets transported to the leaves. The xylem transports water and minerals from the roots to the leaves, then the phloem transports the food from the leaves to the rest of the plant. The water flows by osmosis and the sugars move to the phloem by active transport because it requires energy.

Question 27

4 adaptations plants have to survive:

Answer 27

Thick bark: Limits moisture in rainforests. Thin bark can result in plants not growing on the surface anymore. Drip tips: Leaves have points at the tip to drop the water which prevents fungi and bacteria from effecting the plant. Thick Leaves: Have thicker cuticles that prevent water loss and protect the surface of the leaf. Lianas: Vines that are rooted in the soil and stretch across trees to capture sunlight.

Question 28

What problems might land plants face that water plants do not?

Answer 28

Land plants rely a lot on the weather, while water plants don't because they are in the water. Land plants could get dehydrated without enough precipitation which can prevent photosynthesis from occurring. Land plants also have to support themselves against the force of gravity while water plants don't.

Question 29

Describe how plants could be used as indicators of changing environmental conditions

Answer 29

Climate change can affect plants in many ways. If there is a lack of water this can affect the plants because photosynthesis won’t occur. Rising temperatures can affect plants because they can dry the plants because of the lack of water. The temperature is the most important effect because too much heat and too much precipitation can affect the plant in both ways. Carbon emissions can spread carbon dioxide. Some plants can be affected by too much carbon dioxide, but other plants can benefit from the increase in carbon dioxide because plants absorb carbon and release oxygen. The more carbon there is in the environment the more photosynthesis will occur in some plants. Some people look at the tree rings to see the effect climate change could’ve had on their growth.
