1

name the four processes for which plants require water

photosynthesis
turgor pressure
hydrolysis
transport

2

do xylem cells need to be alive in order for xylem to do their job

no

3

do phloem cells need to be alive in order for phloem to do their job

yes

4

what substances do xylem contain

water and dissolved minerals

5

what substances do phloem contain

sugar and organic substances

6

do insectivorous plants really eat insects

no

7

from a genetic point of view, what is the difference between vegetative reproduction and sexual reproduction in plants

vegetative reproduction leads to offspring with genetic codes that are identical to the parent. sexual reproduction leads to offspring with genetic codes that are similar to the parent.

8

what are the male and female reproductive organs of a flower

the stamen is the male organ
the carpel is the female organ

9

why are the pollen gains and embryo sacs of flowers sometimes considered the gametophyte generation in an alteration of generations life cycle

both structures are multicellular and they both reproduce using gametes

10

what two types of cells are found in a pollen grain

sperm cell and tube nucleus

11

typically, how many cells are in an embryo sack and how many get fertilized

typically there are seven cells in an embryo sack and two of them gets fertilized

12

what is the difference between pollination and fertilization

pollination is the transfer of pollen from an anther to a stigma. fertilization is the act of the sperms fusing with the egg and the large central nucleus in the embryo sac

13

how many sperm cells are used in plant fertilization

two

14

where does the endosperm come from

it comes from the fertilization of the large, two-nucleus cell that is at the center of the embryo sac

15

name three basic parts of the plant embryo

radicle
hypocotyl
epicotyl

16

what is the purpose of a fruit

a fruit allows for the dispersal of seeds to places away from the parent

17

name some ways in which pollen is transferred from the stamens of one flower to the carpel of another

wind
bees
beetles
birds
moths
butterflies

18

why are cotyledons sometimes called "seed leaves"

they form leaf-life structures if they end up rising above ground with the seedling

19

what is the study of life processes in an organism called

physiology

20

what kind of motion is turgor pressure responsible for

nastic movement

21

plants store excess food in the form of what

polysaccharides known as starch

22

what is loam

a mixture of gravel, sand, silt, clay, and organic matter

23

what does the cohesion-tension theory describe

how water moves up a plant through the xylem

24

what is the transport of organic chemicals and food through the ploem

translocation
