Multicellular/Eukaryotes/Contain cell walls
Characteristics of the Plant kingdom
Venus fly trap capturing it's prey
Give an example of a rapid response in plants.
Active transport, therefore ATP is required
How do minerals move from the soil into roots?
Allow plants to respond or adjust to changing environmental conditions
How do plants use hormones?
To produce glucose through process of photosynthesis
How do plants use the energy of sunlight?
How do sugars move through a plant?
If dispersed away from the parent plant
How would a seed face less competition?
Leaf structure reduces water loss,
Shallow fibrous root system to increase surface area for increased water absorption
Cell division (Mitosis), cell elongation, and cell differentiation
Starting from the root cap what is the correct sequence of cell activity in a root?
Multicellular green algae, aka Chlorophyta
The first plants evolved from???
What are stolons?
Xylem and phloem
What are the different types of vascular tissue?
Transport nutrients and water between roots and leaves
What are the main functions of stems?
The shedding of leaves
What do auxin and ethylene influence?
Adequate gas exchange through stomata CO2 is required to generate glucose which is transported to mitochondria for ATP production
What do plants need to survive?
Exchange O2 and CO2 with the atmosphere
What do stomata do?
Controls the photoperiodism of plants
What does phytochrome control?
What does the xylem consist of in angiosperms?
What is a carrot?
A ripened ovary containing seeds
What is a fruit?
A plant hormone that effects the growth and development of fruits
What is a gibberllin?
Has a similar function and role as plant roots, anchor plant, collects water and nutrients
What is a rhizoid?
A plant structure containing: embryo, food source and a protective covering
What is a seed?
Attraction between a water molecule and other substance
What is adhesion?
Male reproductive part of Ferns that produce sperm
What is an antheridium?
A period of decreased activity
What is dormancy?
Early growth stage of a plant embryo
What is germination?
Response from a plant toward gravity /Ensures roots grow into soil
What is gravitropism?
Region of plant that produces new cells
What is meristematic tissue?
Response from a plant toward light
What is phototropism?
Elongation...increasing in length
What is primary growth (in stems)?
Layer of cells enclosing vascular tissue
What is the endodermis?
Anchor and support the plant
What is the function of roots?
What is the outer covering of plants?
Unique mode of seed dispersal, where entire plant aids in delivery system
What is unique about tumbleweeds?
A vascular tissue that conducts water great distances allowing plants to increase in size
What is xylem?
Birds and/or fruit eating bats
What kind of animal would ensure the widest dispersal of a plant's seeds?
Seeds with stickers
What kind of seeds are generally dispersed by animals?
Root tips b/c the apical meristem is actively dividing through Mitosis
What part of a plant would be best to observe cell reproduction?
Sticky secretion on the scales of a cone
What traps pollen grains on coniferous plants?
What type of plant lives the longest?
After fertilization it develops into a seed
What would a pollen grain landing near an ovule produce?
2 haploid sperm nuclei
What would a pollen tube of a gymnosperm contain?
Opening between two bean shaped cells
What would stoma look like?
Active cell division can be seen at the tips of roots and shoots of a plant
What would you find in the meristem regions of plants?
Conservation of water
When plants evolved to live on land what had to happen?
Where are gametophytes of gymnosperms found?
Where are pollen grains produced in angiosperms?
Where are spores produced in ferns?
Where does reproduction occur in angiosperms?
What do Bryophytes need to reproduce?
