PLANTS: A SPACED LEARNING LESSON
2nd Presentation – Fill in the blanks!
By: Andrea Kirk
NONVASCULAR PLANTS
NONVASCULAR PLANTS
Nonvascular: These plants lack ________ _______ to transport water and nutrients. They rely on simple diffusion to move water, and
must live in a moist environment. ______________ grow very tall because they lack
vascular tissue. Lack true ________, ________, and _________.
Some have root-like structures called rhizoids Includes Mosses, ______________, and
Hornworts
NONVASCULAR PLANTS
NONVASCULAR PLANTS
Life Cycle: The __________________ is the dominant
generationDoes not utilize seeds, but uses wind
blown ___________ to disperse the offspring.
_________________sperm requires water to reach and fertilize the egg; another reason why they must live in a moist area.
SEEDLESS VASCULAR PLANTS
VASCULAR PLANTS
VASCULAR PLANTS
Vascular plants have specialized structures:Roots, stems, and leavesDifferentiated tissues: meristematic,
ground, vascular, and dermal tissues. Can grow much _____________ than
nonvascular plants due to their vascular structures.
The life cycle has a dominant _________________ generation, in contrast to the dominant gametophyte in nonvascular plants
TISSUES Vascular plants have _______________ tissues
that perform separate but important functions. Meristematic Tissue: consists of cells that grow
and divide repeatedly. ________________ Tissue: these cells form the
xylem and phloem that transport water and nutrients
Ground Tissue: has cells that are rich in chloroplasts and conducts photosynthesis
________________ Tissue: these cells protect the vascular structures of the plant.
TISSUES IN VARIOUS PLANT PARTS
???___________
MAIN PLANT PARTS
Roots ____________ Leaves
All of these parts contain dermal vascular and ground tissues.
THE ROOTS
Functions: Anchoring Absorption __________________
Structure: Root Hairs – increase the surface area for more
absorption Zone of Elongation Meristematic Zone – part of the root tip where
cells ____________________________to extend the root.
Root Cap – _________________ the root tip
STRUCTURE
_?_ _____?_______
STEM
Function: Connects the roots to the leaves and acts as the plumbing for the plant
Structure: Xylem:
________ way Transports water and minerals upward Stiff, thick walls
Phloem ________ way Transports products of _____________________ and water
up and down __________________walls
STRUCTURE
_______ _______
STRUCTURE
LEAVES
Function: Capture the sunlight and are the main area of _____________________ for the plant.
Structure: Leaf Margins:
LEAVES
Leaf Types
______________
?
LEAF STRUCTURE
Cuticle – waxy and water repellent. Excreted by the epidermis
_____________________ - outer layer of cells Palisade Mesophyll – elongated cells that
contain a lot of chlorophyll Spongy Mesophyll – Round irregular cells that
allow for _______ exchange Stoma – ___________ in the leaves for water and
gas movement (more on the bottom of leaf) Guard Cells – “Guard” the stoma to open and
close it. Vein – contains the _________ and _________ for
the leaf.
LEAF STRUCTURE
PHOTOSYNTHESIS
___________ Products?
TYPES OF VASCULAR PLANTS
Seed: ________________ Angiosperms
_______________: Ferns Whisk ferns Horsetails
SEED VASCULAR PLANTS
Gymnosperms: Ginkgos, Gnetales, cycads, and
____________“____________ seeds” that are not
enclosed in a protective structure. The ovule normally develops on the surface of a scale (cone) or at the tip of a modified leaf.
Conifers are the most abundant gymnosperms and include pine trees
Life Cycle: The __________________ is the dominant portion of the life cycle.
GYMNOSPERMS
Ginkgo
___?_____
Gnetales
Cycad
SEED VASCULAR PLANTS Gymnosperms:
SEED VASCULAR PLANTS
AngiospermsThe ________ _________group of land
plants.“________________ plants” - the
ovule develops inside a protective ovary. The mature ovary becomes a fruit.
Life Cycle: The sporophyte is dominant. ______________ fertilization occurs to produce an endosperm, the food supply, and a zygote.
SEED VASCULAR PLANTS Angiosperms
SEED VASCULAR PLANTSAngiosperms
Two main divisions of flowering plants._________________tyledon: Monocots
One cotyledon (seed leaf) Flower parts in threes ___________ leaf veins Scattered vascular bundles
Dicotyledon: Dicots _________ cotyledons Flower parts in fours and fives Net-like leaf veins Vascular bundles are arranged in a ring.

SEEDLESS VASCULAR PLANTS Include whisk ferns, ___________,
club mosses, and horsetails.Life Cycle: The sporophyte is
dominantUse windblown _____________, not seeds, to
disperse their offspring.The sperm is __________________ and
requires water to reach the egg. These plants are limited to

SEEDLESS VASCULAR PLANTS
SEEDLESS VASCULAR PLANTS
____________ = cluster of sporangia that can be located on the underside of a fern leaf.
Sporangia = enclosure of ___________
SEEDLESS VASCULAR PLANTS: FERN
___________________:An uncurling frond
BRAIN BREAK
Pantomime!! The leader will act out an activity without
speaking. The class will mimic the leader’s actions and
attempt to guess what activity they are doing The winner is the next leader10 minutes
