Answer 1

tap roots, fibrous roots, adventitious root,

Question 2

What are tap roots

Answer 2

one main root grown from the radicle with secondary roots grown off from the main root

Question 3

What are fibrous roots

Answer 3

group of equal sized roots formed when the radicle dies

Question 4

What are adventitious roots

Answer 4

roots that don’t develop form the radicle

Question 5

What are the functions of roots

Answer 5

anchor plant to soil, absorb water and minerals, transport materials to the shoots, store food in some plants

plant that doesn’t contain wood

Question 10

What is lignin

Answer 10

a strengthening material found in some plant cell walls

Question 11

What is a node

Answer 11

the point on a stem at which a leaf is attached

Question 12

What is an internode

Answer 12

the region on a stem between two nodes

Question 13

What is a bud

Answer 13

a potential growth point that may develop into a shoot, leaf or a flower

Question 14

What is a lenticel

Answer 14

an opening on a stem for gas exchange

Question 15

What are the functions of the stem

Answer 15

support the aerial parts of the plant, transport water and minerals to the leaves and flowers, transport food from the leaves, may store food

Question 16

What is the structure of a leaf

Answer 16

attached to stems at nodes, stalk of leaf is called petiole, leaf blade is called the lamina, midrib and veins

Question 17

What is venation

Answer 17

the pattern of veins in a leaf

Question 18

What are the types of leaf venation

Answer 18

parallel venation and net/reticulate venation

Question 19

What are the functions of leaves

Answer 19

make food, gas exchange with the atmosphere, lose water, store food

Question 20

What are the types of tissue in flowering plants

Answer 20

dermal tissue, ground tissue, vascular tissue (xylem and phloem)

Question 21

What is the function of dermal tissue

Answer 21

protect the plant

Question 22

What is the function of ground tissue

Answer 22

photosynthesis, storage of food and waste

Question 23

What is the function of xylem

Answer 23

transport water and minerals, gives mechanical support to the plant

Question 24

What is the function of phloem

Answer 24

transport food

Question 25

What are the 2 types of xylem

Answer 25

tracheid and vessel

Question 26

What is the appearance of tracheids

Answer 26

long, tapering cells with hollow lumen/insides, pits in walls to let water pass through, supported by lignin

Question 27

What is the appearance of vessels

Answer 27

tubular structures joining end to end, wider, no end walls, pits in walls to let water pass through, hollow lumen/inside, supported by lignin

Question 28

What is the one type of phloem

Answer 28

sieve tube

Question 29

What is the appearance of sieve tubes

Answer 29

hollow lumen/inside, sieve plates at ends of them, companion cells attached

Question 30

What is the function of the companion cell

Answer 30

controls the activities of the sieve tube elements

Question 31

What are the differences between xylem and phloem

Answer 31

Xylem: carries water and minerals, dead, has lignin, no companion cells. Phloem: carries food, living, no lignin, has companion cells

Question 32

What is the location of tissues in a root

Answer 32

xylem middle in X shape, phloem surround xylem, ground tissue surround the one vascular bundle, dermal tissue around outside

Question 33

What is the location of plant tissue in a dicot stem

Answer 33

Xylem and phloem in a ring shape with xylem on inside and phloem on outside

Question 34

What is the location of plant tissue in a monocot stem

Answer 34

vascular bundles are scattered around

Question 35

What cotyledon

Answer 35

seed leaf

Question 36

What are the diffences between monocot and dicot plants

Answer 36

Monocot: one cotyledon, parallel veins, vascular bundles scattered, flower parts in multiples of 3. Dicot: two cotyledons, network of veins, vascular bundles in ring, flower parts in multiples of 4 or 5
