Plant Evolution
This is the organism that all currently living plants evolved from
green algae
A group of cells that together perform a specialized function.
A tissue
This structure anchors plants and absorbs water/nutrients
Roots
The ovary
This substance is moved specifically through phloem
sugars
The primary difference between vascular and nonvascular plants
vascular plants have xylem and phloem
The two types of organ systems in vascular plants
root system and shoot system
The main function of the cuticle
prevent water loss
The main difference between monocots and dicots
monocots have 1 cotyledon (1 leaf in seed) while dicots have 2
osmosis
This type of fungi aided in the transition of plants to land
mycorrhizae
this type of growth allows plants to grow in width
secondary growth
This type of tissue includes cells for storage, photosyntesis, support, and transport
ground tissue
The main difference between monoecious and dioecious plants
Monoecious have both sexes on a single plant while dioecious have both parts on separate plants
transpiration
The evolutionary benefit of root hairs
Helps to increase surface area for collecting water near roots
This term is used to describe buds growing at a plant node
axillary buds
Carrots and beets serve as an example of this type of root system
taproot system
This type of flower has both male and female parts
complete flowers
This structure serves as a channel connecting plant cells used for transport
plasmodesmata
The 3 main features of plant cells
have organelles
have a cell wall made of cellulose
have chloroplasts (photosynthesis) and mitochondria
A plant's leaves stop growing once they grow a certain length. This type of growth is known as _______
determinate growth
What is the function of guard cells
open and close stomata to balance water and gas exchange
What is self incompatibility?
A plant's ability to reject pollen from itself or from close relatives
Why do plants wilt?
loss of turgor pressure from water loss
