Plant Diversity

Plants are

-multicellular organisms
-autotrophs
-capable of photosynthesis
-eukaryotes

What part of plant cells contains chlorophyll and carries out photosynthesis

chloroplast

In plants,

the diploid zygote develops into the sporophyte

The parts of the plant that absorb water and minerals are the

roots

The parts of the plant that conduct water and dissolved minerals from the roots to the leaves are the

xylem

The parts of the plant that allow for gas exchange are the

stomata

The ____________ provides a waxy coating that minimizes water loss from leaves of the plant

cuticle

The two types of vascular tissue in most plants are

xylem and phloem

Ferns have advantage over bryophytes in that ferns

have a vascular system, which allow them to grow taller

Gymnosperms have an advantage over ferns in that gymnosperms

produce pollen and do not require water to reproduce

In alternation of generations, a diploid sporophyte goes through meiosis to form __________ spores

halpoid

In alternation of generations, a haploid gametophyte goes through mitosis to form a ____________ gamete

haploid

In plants that have two haploid gametes fuse during fertilization, the zygote is

diploid

What evolved in terrestrial plants to provide support and transport for water and minerals

vascular tissues

Gymnosperms and angiosperms evolved ____________ allowing them to live and reproduce in drier habitats than bryophytes and seedless vascular plants

pollen grains and seeds

Bryophytes lack vascular tissue and lignin and therefore cannot

grow tall

Which group of plants have phloem and xylem but lack seeds, flowers, and fruit?

ferns, club mosses, horsetails, and whisk ferns

The four phyla of the gymnosperms are

conifers, cycads, ginkgos, and gnetophytes

The two groups of angiosperms are

monocots ad eudicots

The fruits of plants function in

both protecting and dispersing seeds
