PLANT STRUCTURE AND FUNCTIONS Flashcards
are complex structures with several organelles lacking in animal cells
Plants cells
Plants have two organ systems
ROOT SYSTEM and the
SHOOT SYSTEM
is typically belowground and consists of roots, which specialized in water and nutrient absorption
root system
consists of stems and leaves and is typically aboveground
shoot system
Main tissue types
Epidermal, Vascular tissues, and Ground
Functions in supporting the plant and transporting materials
Stem
Functions in the presentation for food and function in photosynthesis
Leaves
Types of Plants
*Non-vascular Plants
*Vascular Plants
*Seed Plants
The most primitive types of plants lack vascular tissue, the tube like structures through which water and other materials move inside a plant.
Non-vascular Plants
the process that allows water to diffuse across a cell membrane
osmosis
are small and
grow on the surface of wet
soil
Liverworts and their
relatives
are the small plants that form a green
carpet on the floor of many forests
also grow on trees and on rock surfaces
Mosses
are true land plants because they have evolved ways to survive independent of wet environments
Vascular plants
tracheophytes
look a great deal like
green feathers.
Fern leaves
are small
evergreen plants with
needle-like or scale-like leaves
Club mosses
are vascular plants that reproduce using seeds
Seed plants
Seed plants can be divided into two groups
gymnosperms and
angiosperms
are vascular plants that produce seeds that are not enclosed within a fruit
Gymnosperms
flowering
plants and their seeds are
enclosed in fruits.
angiosperms
The _______ protects the
seeds as they develop
fruit
These seedless vascular plants reproduce in a two generation life cycle
- one that produces spores
- and one that does not produce spores
*A life cycle is a continuous process and does not have a true beginning or end.
TRUE
One place to begin describing the process of the life cycle of an angiosperm is at
germination
*An adult angiosperm grows ________, which then go through the process of pollination.
flowers
