Answer 4

1. They absorb nutrients, minerals, and water from the soil

2. They serve as an anchor for the plant

Question 5

What does the stem do?

Answer 5

1. Contains the phloem and the xylem which transport the water and sugars throughout the plant
2. Central transport system that connects the leaves and the roots

Question 6

What does the flower do?

Question 10

What THREE parts of the leaf can you see without the use of a microscope? How would you describe each part?

Answer 10

Blades - The blade is a broad flat section of the leaf.

Petioles - The narrow stem-like part of the leaf.

Veins - The veins carry water and other substances throughout the plant.

Question 11

xylem

Answer 11

Bundles of veins that carry water and minerals up to the leaves

Question 12

phloem

Answer 12

Vein bundles that carry food from the leaves to the rest of the plant

Question 13

Tanspiration

Answer 13

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as from leaves

Question 14

epidermis:

Answer 14

Outer surface of the leaf

Question 15

mesophyll

Answer 15

Region between the upper and lower epidermis

Question 16

cuticle

Answer 16

Waxy film that covers the epidermis

Question 17

What is the difference between mitosis and meiosis?
