plant test Flashcards
what are the 2 types of plants
vascular and non vascular
what is the difference between non vascular and vascular plants
vascular have vascular tissue
non vascular don’t have vascular tissue
what is vascular tissue
specialized tissues for the transport of water, nutrients and products of photosynthesis
example of non vascular plants
algae, bryophytes (mosses,hornworts)
example of vascular plants
ferns, gymnosperms, angiosperms
what are the 3 different types of algae phyla
chlorophyla, rhodophyla, phaeophyla
characteristics of algae
- always found in aquatic or moist environments
- don’t have true leaves and stems called blades and stripes
- life cycle follows alternation of generations
what is the alternation of generations
found in all plants where for part of the life cycle the plant is haploid and other part is diploid
explain alternation of generations
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
describe rhodophyla
-red colour
-mostly found in ocean environments
most are multicellular
stores food in form of starch
describe chlorophyla
- green colour
- unicellular, multicellular or colonial
- found in freshwater
- store food in starch form
describe phaeophyla
- brown colour
- store food in starches and oil form
- found in marine environments temperate and artic areas
characteristics of ferns
- has feathery/leafy frounds
- gametophyte much smaller and separate from sporophyte in alternation of gen
characteristics of mosses
- clumped habit
- gametophyte and sporophyte is attached in alternation of gene
what are gymnosperms
all bear cones, with naked seeds
