Organ and tissue (lab 2)

Question 1

Differences in Monocots (cotyledon, leaf, stem, flower)

Answer 1

• single (mono) cotyledon
• long narrow leaf and parallel veins
• in the stem, vascular bundles scattered, no structure
• floral parts in multiple of 3

Question 2

Differences in Dicots (cotyledon, leaf, stem, flower)

Answer 2

• double (di) cotyledon
• broad leaf with network of veins
• in the stem, vascular bundles in a ring
• floral parts in multiple of 4 or 5

Question 3

pith

Answer 3

centre of the stem

Question 4

xylem

Answer 4

tissue responsible for the transport of water and minerals to the plant
(vessels are dead cells)

Question 5

phloem

Answer 5

tissue responsible for the transport the the food to the plant

Question 6

cortex

Answer 6

keeps structure to the plant

Question 7

epiderm

Answer 7

protects the plant, has the stomata

Question 8

stomata

Answer 8

responsible for the gas exchange

Question 9

cambium

Answer 9

between the xylem and phloem, and thicken the stem or root of woody plants

Question 10

Chloroplast

Answer 10

plastids containing chlorophyll pigment

Question 11

Chromoplast

Answer 11

plastids containing other pigments than chlorophyll

Question 12

Amyloplast

Answer 12

starch-forming plastids (found on potatoes or carrots)

Question 13

cortical

Answer 13

thin layer of cells with oil or tricons (cell cortex)

Question 14

mesophyll

Answer 14

palisade long cells and spongy cells

Question 15

long cells

Answer 15

responsible for the photosynthesis

Question 16

collenchyma cells

Answer 16

provide structure and support to the cell

Question 17

sieve tubes

Answer 17

cells in the phloem transporting the sugar produced from photosynthesis to the plant

Question 18

vessels

Answer 18

dead cells in the xylem transporting the water and minerals from the roots to the plant

Question 19

parenchyma cells

Answer 19

found in cortex or xylem for structure and suport
