Plant structure

Question 1

Which plant types have seeds?

Answer 1

Gymnosperm and angiosperm

Question 2

which plants have apical growth?

Answer 2

mosses, ferns, gymnosperms and angiosperms (not liverworts)

Question 3

what is a meristem?

Answer 3

collection of undifferentiated cells

Question 4

differences between monocot and eudicot?

Answer 4

monocot:
cotyledon has one leaf
vascular bundles in random patterns
parallel leaf veins
flower parts in bundles of 3 secondary growth rare

Question 5

cotyldeon

Answer 5

first photosynthetic structure that emerges from a seed

Question 6

hypocotyl

Answer 6

stem of cotyledon

Question 7

three types of ground tissue

Answer 7

parenchyma, collenchyma, sclerenchyma

Question 8

ground tissue is _______ (one cell type)

Answer 8

simple

Question 9

describe parenchyma cells

Answer 9

located in tissue of cortex, pith, mesophyll, fruit.
performs photosynthesis, storage, transport, hormone secretion
living at plant maturity - retains meristemic ability.
transfer cells: xylem and phloem

Question 10

describe collenchyma cells

Answer 10

stringy, non-lignified primary walls. provide support for growing stems.
located in bundles below the epidermis.
living at plant maturity

Question 11

describe sclerenchyma cells

Answer 11

dead at plant maturity
made of fibres and sclerids
supports plant parts no longer growing, ie seed coats

Question 12

xylem is ________ to phloem

Answer 12

interior

Question 13

three types of tissue

Answer 13

ground, vascular and dermal

Question 14

SAM

Answer 14

undifferentiated cells that produce leaf and bud primordia, are source of ground tissue

dermal tissue specialized cells

Answer 22

guard cells, trichomes

Question 23

trichomes function

Answer 23

defense, storage of scent molecules

Question 24

dermal tissue functions

Answer 24

defense, water/gas exchange, protect from mechanical damage
