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

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
