plant test

Question 1

what are the 2 types of plants

Answer 1

vascular and non vascular

Question 2

what is the difference between non vascular and vascular plants

Answer 2

vascular have vascular tissue

non vascular don’t have vascular tissue

Question 3

what is vascular tissue

Answer 3

specialized tissues for the transport of water, nutrients and products of photosynthesis

Question 4

example of non vascular plants

Answer 4

algae, bryophytes (mosses,hornworts)

Question 5

example of vascular plants

Answer 5

ferns, gymnosperms, angiosperms

Question 6

what are the 3 different types of algae phyla

Answer 6

chlorophyla, rhodophyla, phaeophyla

Question 7

characteristics of algae

Answer 7

• always found in aquatic or moist environments
• don’t have true leaves and stems called blades and stripes
• life cycle follows alternation of generations

Question 8

what is the alternation of generations

Answer 8

found in all plants where for part of the life cycle the plant is haploid and other part is diploid

Question 9

explain alternation of generations

Answer 9

the gametophyle produces two gametes which fusion together into a zygote the zygote goes into mitosis into a sporephyte the sporophyte goes into meiosis and produces spores

Question 10

describe rhodophyla

Answer 10

-red colour
-mostly found in ocean environments
most are multicellular
stores food in form of starch

Question 11

describe chlorophyla

Answer 11

• green colour
• unicellular, multicellular or colonial
• found in freshwater
• store food in starch form

Question 12

describe phaeophyla

Answer 12

• brown colour
• store food in starches and oil form
• found in marine environments temperate and artic areas

Question 13

characteristics of ferns

Answer 13

• has feathery/leafy frounds

- gametophyte much smaller and separate from sporophyte in alternation of gen

Question 14

characteristics of mosses

Answer 14

• clumped habit

- gametophyte and sporophyte is attached in alternation of gene

Question 15

what are gymnosperms

Answer 15

all bear cones, with naked seeds

Question 16

what are the 4 divisions of gymnosperms

Answer 16

conifers, cycads, ginkgoes, gnetophytes

Question 17

describe conifers

Answer 17

• in cooler regions and in desert habitats
• leaf curl to reduce water loss
• cone bearing seed plant with needles like leaves

Question 18

example of conifers

Answer 18

spruce trees, pine trees, junipers

Question 19

describe cycads

Answer 19

seed plants have stout and woody trunks

Question 20

describe ginkgoes

Answer 20

-fan like leaves
yellow flowers
-Chinese plant

Question 21

describe gnetophytes

Answer 21

cones

angiosperms like leaves

Question 22

what are angiosperms

Answer 22

they have flowers and bear fruit

Question 23

what are the 2 classes of angiosperms

Answer 23

monocots and dicots

Question 24

describe monocots

Answer 24

• single cotyledon
• flower parts in multiples of 3
• leaves with parallel lines
• die off each year
• vascular bundles scattered randomly in stems

Question 25

example of monocots

Answer 25

lilies, corn, bananas

Question 26

describe dicots

Answer 26

-two cotyledons -flowers parts in multiples of 4 or 5 - leaves with net like veins - stems grow thicker year to year vascular bundles in a ring in stems

Question 27

what is the female part in flower called

Answer 27

pistil

Question 28

what are the female parts

Answer 28

stingma, style, pollen tube, ovary, ovule, eggs

Question 29

what is the male part in a flower called

Answer 29

stamen

Question 30

what are the male parts

Answer 30

anther, filament

Question 31

what is xylem and phloem

Answer 31

xylem distributes water and dissolved minerals upward through the plant The phloem carries food downward from the leaves to the roots

Question 32

what is algae

Answer 32

aquatic plant that contain chlorophyll but lacks true stems,roots, leaves and vascular tissue

Question 33

what is a bryophyte

Answer 33

small flower less green plant like mosses or liverworts

Question 34

archegonium

Answer 34

female reproductive organ in ferns and mosses

Question 35

what is the male reproductive organ in ferns and mosses

Answer 35

anteridium
