last group of plants to evolve

angiosperms

trait that separates ferns from mosses

vascular tissue

all plant groups have in common

cuticle

plant with pollen and seeds but no flowers

gymnosperms

ferns die in arizonia because

there is not enough water for reproduction

pollen is important because

helps sperm travel without water

female flower parts

carpels/pistils

pollination vs fertilization

pollination = pollen lands on stigma, fertilization = pollen meets ovule

function of fruit

seed dispersal

brown structures on apple bottom

parts of flower that shrunk as fruit formed

pit/seed developed from the

ovule

embryo gets energy from

carbohydrates stored inside the seed

waxy plant layer

cuticle

function of stoma

allow CO2 in and O2 out

water loss from stomata

transpiration

air spaces help

allow gasses to move through the leaf

what tissue transports sugars in plants

phloem

sugar moves

from the leaves to the roots
