Tiny organs that work inside the cell
Let’s review some important parts of the plant cell
Cell Membrane
Cell Wall
Provides Protection and support
Made of cellulose
The Cell
If a plant does not receive enough water it will wilt.
Osmosis – the movement of water from a high concentration to a low concentration
Contains CHLOROPHYLL
Makes food for cell
(Photosynthesis – captures
ENERGY IN SUNLIGHT

“Green jelly beans”
Nonvascular: Do not contain
tubes to carry water up and down plant
Algae◦ Chlorophyta◦ Phaeophyta◦ Rhodophyta
Bryophyta◦ Mosses◦ Liverworts
Vascular:Do have tubes to
carry water, usually taller
Ferns Gymnosperms Angiosperms
Simple plants with no …◦ Roots◦ Stems◦ Leaves
There are three types …
Chlorophyta

Rhodophyta
Algae that is the color GREEN
Algae that is the color BROWN
Phaeostrophion irregulare
Analipus japonicus Nereocystis Nereocystis luetkeanaluetkeana
Algae that is the color RED
Antithamnion plumula Delesseria sanguinea Porphyra perforata
1. Plant division made up of nonvascular plants that live in moist places.
2. Examples include a) Moss- simple rootless plant with leaves arranged in a spiral around a leafy stem.
BEDDING PEAT MOSS –
gardeners SPHAGNUM MOSS –
grows in a BOG (acidic wetland) ◦ wetlands – areas of
land that are saturated with water for a period of time
b) Liverworts – simple rootless plants with or without stems & leaves.
Also called the Tracheophyta
Includes three main groups
Ferns Gymnosperms Angiosperms
Have large leaves that are divided into smaller parts that also look like miniature leaves (called fronds)
FRONDS
Reproduce through spores (which are located underneath the leaves).
Spore case
1. Have “male” and “female” cones that produce pollen and ovules
2. If pollination occurs, seeds are produced in the female cone that are not protected by a fruit (outside covering).
FEMALE
MALE
Examples:
Giant Redwoods - the tallest trees
Fir tree
Pine tree
ginkoe
hemlock
Flowering plants
2) Produce seeds inside a fruit.
3) The two main types of angiosperms are based on the number of cotyledons (the part of the seed that stores FOOD.
1) Have flower parts in threes
1) Have flower parts in fours or fives
2) Narrow leaves with parallel veins
2) Broad leaves with branched veins
3) Vascular tissue (vessels) scattered throughout the stem.
3) Vascular tissue in a ring.
4) Seeds have one seed leaf
4) Seeds have two seed leaves

a) Stamens
1- Male reproductive organs

2) Have two parts

b) Pistils
1- Female reproductive organs
Pistil
Ovary – produces ovules (female gametes)
Style – short stalk
Stigma – sticky extension of stalk that catches pollen.
Ovules growing in the ovary
Pollen sticking to the pistil’s stigma.

C) Sepals- Leaflike parts that protect the flower.
d) Petals – Attract pollinators.
Flower Parts
Sepal
Petal
Taking pollen from one plant with a certain trait and placing it on a plant with a different trait. For example, taking pollen from a short plant and placing it on a plant that is tall.
Cross pollination
a) After pollen lands on stigma a tube grows down the style to an ovule.
b) The fertilized zygote develops into a seed.
c) The ovary that surrounds the ovules develops into a fruit.
c) The ovary that surrounds the ovules
develops into a fruit (if the fruit dries out it becomes a shell).
Produces nuts, grainsAcorns, etc.
