2
Organelles Tiny organs that work inside the cell
Let’s review some important parts of the plant cell
3
The Cell Cell Wall Cell Membrane
4
The Cell Cell Wall: Provides Protection and support Made of cellulose
5
The Cell Vacuoles: Larger in plants Osmosis – the movement of water from a high concentration to a low concentration If a plant does not receive enough water it will wilt.
6
The Cell “Green jelly beans” Contains CHLOROPHYLL Makes food for cell
Chloroplast: “Green jelly beans” Contains CHLOROPHYLL Makes food for cell (Photosynthesis – captures ENERGY IN SUNLIGHT (equation)
7
Classification of Plants Nonvascular vs. Vascular Plants
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
8
ALGAE Simple plants with no … There are three types … Roots Stems
Chlorophyta ALGAE Simple plants with no … Roots Stems Leaves There are three types … Phaeophyta Rhodophyta
9
Chlorophyta Algae that is the color GREEN
10
Nereocystis luetkeana
Phaeophyta Algae that is the color BROWN Nereocystis luetkeana Analipus japonicus Phaeostrophion irregulare
11
Rhodophyta Algae that is the color RED Antithamnion plumula
Delesseria sanguinea Porphyra perforata
12
Bryophyta Plant division made up of nonvascular plants that live in moist places. Examples include a) Moss- simple rootless plant with leaves arranged in a spiral around a leafy stem.
13
USES OF MOSS 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
14
Bryophyta b) Liverworts – simple rootless plants with or without stems & leaves.
15
Vascular Plants Also called the Tracheophyta
Includes three main groups Ferns Angiosperms Gymnosperms
16
FERNS Have large leaves that are divided into smaller parts that also look like miniature leaves (called fronds) FRONDS
17
FERNS Reproduce through spores (which are located underneath the leaves). Spore case
18
Gymnosperms Have “male” and “female” cones that produce pollen and ovules If pollination occurs, seeds are produced in the female cone that are not protected by a fruit (outside covering). FEMALE MALE
19
Gymnosperms Examples: Pine tree hemlock Fir tree ginkoe
Giant Redwoods - the tallest trees hemlock Fir tree ginkoe
20
Angiosperms Flowering plants
21
2) Produce seeds inside a fruit.
Angiosperms 2) Produce seeds inside a fruit.
22
Angiosperms 3) The two main types of angiosperms are based on the number of cotyledons (the part of the seed that stores FOOD.
23
Monocots Dicots 1) Have flower parts in threes
1) Have flower parts in fours or fives
24
Monocots Dicots 2) Narrow leaves with parallel veins
2) Broad leaves with branched veins
25
Monocots Dicots 3) Vascular tissue (vessels) scattered throughout the stem. 3) Vascular tissue in a ring.
26
Monocots Dicots 4) Seeds have one seed leaf
4) Seeds have two seed leaves
27
Monocot Examples Corn Wheat Daffodils Grasses Lilies Palms
28
Dicot Examples Beans Roses Oaks Dandelions Tomatoes Maples

4- Parts of a Flower Stamens Stamens 1- Male reproductive organs
32
Stamens 2) Have two parts Filament- stalk Anther- where pollen is made
33
Pollen grain forming on anther
Pollen released into the air

4- Parts of a Flower b) Pistils 1- Female reproductive organs Pistil
38
2) Pistils have three parts
Ovary – produces ovules (female gametes) Style – short stalk Stigma – sticky extension of stalk that catches pollen.
39
Pistil parts
40
Pistil ovary Ovules growing in the ovary
41
Pistil Stigmas Pollen sticking to the pistil’s stigma.

44
Sepals & Petals C) Sepals- Leaflike parts that protect the flower.
d) Petals – Attract pollinators.
45
Flower Parts Petal Sepal
46
How does pollen get from the stamen to the pistil?
Insect Pollinators Wind
47
Humans can also selectively pollinate flowers:
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
48
Seed & Fruit Production
a) After pollen lands on stigma a tube grows down the style to an ovule.
49
Seed & Fruit Production
b) The fertilized zygote develops into a seed.
50
Seed & Fruit Production
c) The ovary that surrounds the ovules develops into a fruit.
51
Seed & Fruit Production
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.
52
Tomato flower develops into fruit.
