Answer 10

waxy substance that covers leafs and maintains their moisture balance

Question 11

Epidermis (leaf):

Answer 11

secretes waxy cuticle which protects leaf

Question 12

Mesophyll (leaf):

inner part of leaf

Question 13

Palisade layer (leaf):

Answer 13

upper section of mesophyll responsible for most of the chlorophyll that occurs on a plant

Question 14

Vascular Bundles (Leaf):

Answer 14

Makes up veins: Section of the leaf that transports sugars produced in leafs.

Question 15

Spongy layer (leaf):

Answer 15

Lower layer of mesophyll. Contains large air spaces when allow for passage of gases:

Question 16

Guard cells:

Answer 16

open and close stomata

Question 17

Stomata:

Answer 17

Allow moisture and gases to pass in and out of leaf

Question 18

Roots:

Answer 18

Provide water and needed nutrients to the plant

Question 19

Lateral roots:

Answer 19

Extend horizontally

Question 20

Primary Roots:

Answer 20

extend downward

Question 21

Root Cap:

Answer 21

Composed of dead, thick-walled cells that protect the tip of the roots as it burrows deeper

Question 22

Meristematic Region: (roots)

Answer 22

Just above root cap. Has undifferentiated cells that carry out mitosis and grow to form the ELONGATION REGION

Question 23

Elongation Region: (roots)

Answer 23

Just above the MERistematic region. Has cells that differentiate which grow and form large vacuoles

Question 24

Maturation Region

Answer 24

Just above Elongation Region. Where cells differentiate more to form various root tissues

Question 25

Primary root tissue

Answer 25

Different types of root tissues found in Maturation Region of roots (root hairs, Epidermis)

Question 26

Root hairs:

Answer 26

reach between soil particles to retrieve water and minerals

Question 27

Epidermis: (roots)

Answer 27

One cell layer thick membrane which seres to protect the root and absorb nutrients

Question 28

Cortex: (roots)

Answer 28

Just inside of Epidermis. Made of large PARENCHYMA CELLS.

Question 29

Parenchyma Cells

Answer 29

Thin-walled cells loosely packed to allow for flow of gases and minerals

Question 30

Endodermis

Answer 30

Tightly connected cells that act as filters

cohesion

Answer 32

Hydrogen bonding in water in xylem

Question 33

Cohesion-tension process

Answer 33

The way in which water is transported up in the xylem

Question 34

Transpiration

Answer 34

Evaporation of water in plants

Question 35

Answer 35

Active transport

Question 36

The pressure created by the water-sugar solution in phloem because osmosis has occurred…

Answer 36

the solution to be pushed through sieve plates to all areas of the plant
