Tiny organs that work inside the cell Let’s review some important parts of the plant cell
Cell Membrane Cell Wall
Cell Wall: Provides Protection and support Made of cellulose
The Cell Vacuoles: Larger in plants If a plant does not receive enough water it will wilt. Osmosis – the movement of water from a high concentration to a low concentration
Chloroplast: Contains CHLOROPHYLL Makes food for cell (Photosynthesis – captures ENERGY IN SUNLIGHT (equation) “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 … ChlorophytaPhaeophytaRhodophyta
Algae that is the color GREEN
Algae that is the color BROWN Phaeostrophion irregulare Analipus japonicus Nereocystis luetkeana
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
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
Corn Palms Lilies Daffodils Wheat Grasses
Oaks DandelionsMaples Beans Roses Tomatoes
a) Stamens 1- Male reproductive organs Stamens
2) Have two parts Filament Anther Filament- stalk Anther- where pollen is made
Pollen released into the air Pollen grain forming on anther
Stamen Flower Parts
Flower Parts Filament
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.
Flower Parts Pistil
Flower Parts Stigma Style Ovary
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, grains Acorns, etc.
