Main Ideas
What is a Plant? (characteristics)
Details
1) Autotroph (produces own food)
2) Eukaryotes – many cells
3) Plant cells have cell walls
4) Photosynthesis – Sun provides energy
5) Tissue- groups of cells
What are the parts of a plant cell?
1) Nucleus
2) Vacuole – large storage sac( food and waste)
3) Chloroplast- (green) food is made
4) Cell wall - Outer layer, rigid layer
5) Cell Membrane- inner layer, jiggles, squishy
How do plants survive?
1) Obtain water and nutrients
2) Transport materials (water and minerals)
Thru vascular tissue (tube like structure)
3) Reproduce – fertilization – egg+sperm join
4) Retain (hold in) water - Cuticles on leaf
5) Support their bodies
What are the two groups of plants?
1) Nonvascular
-
Low growing to ground
No roots for absorbing
Live in damp shady areas
Ex: mosses and liverworts
2) Vascular
- able to live in dry area, grow tall
- true vascular tissue, reproduce seeds
What are the two types of Vascular plants?
1) Gymnosperm - reproduce seeds
Do not produce flowers and seeds
2) Angiosperms- produce flowers and seeds
How are plants identified?
What are the life cycles of a plant?
Chlorophyll- green pigment found in chloroplasts
1) Sporophyte- produce seeds
2) Gametophyte - produce 2 kinds of sex cells
______________________Types of Seed plants_____________________________P. 151 – 157
What are gymnosperms?
A seed plant that produces naked seeds.
(not enclosed by a protective fruit)
-
Have needlelike or scalelike leaves
Oldest type of seed plant
Ex. Cycads, conifers, ginkgoes, and
gnetopytes
What are angiosperms?
A seed plant that produce flowers
(produce seeds that are enclosed in fruits)
Types of Angiosperms?
Monocot- have only one seed leaf
Ex. Corn and wheat
Dicot - have two seed leaves
Ex. Beans and apples
Parts of a flower
1)
Petal
colorful structure( attracts pollinators)
2)
Sepal
Protects developing flower ( leaf like)
3) Stamen
a. Anther
b. Filament
4)
Pistil
a. Stigma
b. Style
c. Ovary
What is pollination?
male reproductive parts
produces pollen
stalk like ( holds up anther)
Female reproductive parts
sticky tip of pistil ( collects pollen)
slender tube
protects the seeds as it’s developing ( holds ovules)
The transfer of pollen from Male reproductive structure
To the female ( pollen transfers to stigma)
What is cross-pollination?
Plants that can only be fertilized from pollen of another plant
What is fertilization?
When sperm cell joins with an egg cell.
Examples of pollinators
bees, bats, and hummingbirds
_____________________Seed Plants_________________________________________P. 136
What two Characteristics are
Common to all seed plants?
1) Vascular Tissue
A) Phloem- transports food
B) Xylem- transports water and minerals
2) Uses pollen and seeds to reproduce
How do seeds become new plants?
1) Seed structure
a) Embryo –fertilized egg (zygote)
b) Cotyledon- stores food
c) Seed coat- protects seed
2) Seed Dispersal (scattering)
a) organisms
b) wind
c) water
d) ejection
3) Germination – embryo begins to grow out of seed
What is the main function of roots, stems,
Roots- anchor plants in ground, absorb water, and
And leaves?
Store food
Stems- provides support and carries substances to
Roots and leaves
Leaves- captures sun’s energy to carry out
Food making process
a) Stomata – Pores at the surface of the leaf
That open and close to control gases
entering and leaving the leaf
b) Transpiration - the process by which
water evaporates from plants leaves
Plant Response to Growth ( P. 160-163)
What are the three stimuli that
1) touch 2) light 3) gravity
Produce plant response?
How do plants respond to seasonal
The amount of darkness a plant receives
Change?
Determines the time of flowering in many plants
( photoperiodism- length of night and day)
How long do different angiosperms live?
Annual- complete life cycle within one year
Biennials- complete life cycle , two years
Perennials- plants that live more than 2 yrs
Photosynthesis ( p. 114-119)
What is Photosynthesis?
1) Plant captures energy from the sun
2) That energy produces food
Photsynthesis Equation
Carbon Dioxide + Water ----- Sugar + Oxygen
CO2 + H20 --- C6 H12 O6 + O2
