Plants Flashcards
What materials do plants need in order to stay alive?
Water, light, minerals, gas exchange(oxygen and carbon dioxide) , ability to move.
What are the basic characteristics of all plants?
Multicellular, eukaryotic, autotroph, photosynthetic, cell wall Made out of cellulose , and nonmobile.
What role Do plants play in the food chain?
- They are the producers
- bottom of the food chain
- base
- providers without them it’s no life
What organism is believed to be the ancestor of modern plants?
Green algae
Bryophyte
Moss
Gymnosperm
Pine cone
Angiosperm
Flowering plant
Mitosis
Makes perfect copy of cell
Meiosis
Make sex calls gametes: sperm, eggs , etc.
Cellulose
What cell walls are made up of.
Diploid
Cell has both sets
two sets of DNA
Haploid
Cell has one set
Sporophyte
Plant with diploid cells
Gametophyte
plant with haploid cells
Meiosis make haploid cells called …
Spore
Makes Mitosis
eggs are hidden
pollen=sperm
Gamete
Pollination
When the seed falls out and starts to pollen( spreading pollen from flower to flower)
Fertilization
Egg+ Sperm
Zygote
Baby plant
first cell
Traits that all bryophytes share
- short
- must live Nearwater
- no seeds
- non vascular
- need less light and nutrients than larger plants
Traits that all gymnosperms share
- “naked” seed protected by cones
- wind pollination
- can be very tall
- vascular tubes to move :Xylem-water & Phloem-food
Traits that all angiosperms share
- vascular tubes to move :Xylem-water & Phloem-food
- flowers contain ovaries
- animal pollination
- seed contained inside a fruit
Embryo/Seed Coat/Endosperm
Seed Coat- the outside of the seed.
Embryo- “baby plant” - Zygote
Endosperm- food for the embryo
What is the purpose of the fruit?
To hold and spread it seeds around
