2  Tiny organs that work inside the cell  Let’s review some important parts of the plant cell

3 Cell Membrane Cell Wall

4 Cell Wall: Provides Protection and support Made of cellulose

5 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

6 Chloroplast: Contains CHLOROPHYLL Makes food for cell (Photosynthesis – captures ENERGY IN SUNLIGHT (equation) “Green jelly beans”

7 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

8  Simple plants with no … ◦ Roots ◦ Stems ◦ Leaves  There are three types … ChlorophytaPhaeophytaRhodophyta

9  Algae that is the color GREEN

10  Algae that is the color BROWN Phaeostrophion irregulare Analipus japonicus Nereocystis luetkeana

11  Algae that is the color RED Antithamnion plumula Delesseria sanguinea Porphyra perforata

12 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.

13  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 b) Liverworts – simple rootless plants with or without stems & leaves.

15  Also called the Tracheophyta  Includes three main groups Ferns Gymnosperms Angiosperms

16  Have large leaves that are divided into smaller parts that also look like miniature leaves (called fronds) FRONDS

17  Reproduce through spores (which are located underneath the leaves). Spore case

18 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

19  Examples: Giant Redwoods - the tallest trees Fir tree Pine tree ginkoe hemlock

20  Flowering plants

21  2) Produce seeds inside a fruit.

22  3) The two main types of angiosperms are based on the number of cotyledons (the part of the seed that stores FOOD.

23  1) Have flower parts in threes 1) Have flower parts in fours or fives

24 2) Narrow leaves with parallel veins 2) Broad leaves with branched veins

25 3) Vascular tissue (vessels) scattered throughout the stem. 3) Vascular tissue in a ring.

26 4) Seeds have one seed leaf 4) Seeds have two seed leaves

27 Corn Palms Lilies Daffodils Wheat Grasses

28 Oaks DandelionsMaples Beans Roses Tomatoes

31 a) Stamens 1- Male reproductive organs Stamens

32  2) Have two parts Filament Anther Filament- stalk Anther- where pollen is made

33 Pollen released into the air Pollen grain forming on anther

34 Stamen Flower Parts

35 Anthers

36 Flower Parts Filament

37 b) Pistils 1- Female reproductive organs Pistil

38  Ovary – produces ovules (female gametes)  Style – short stalk  Stigma – sticky extension of stalk that catches pollen.

39

40 Ovules growing in the ovary

41 Pollen sticking to the pistil’s stigma.

42 Flower Parts Pistil

43 Flower Parts Stigma Style Ovary

44 C) Sepals- Leaflike parts that protect the flower. d) Petals – Attract pollinators.

45 Flower Parts Sepal Petal

46

47 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 a) After pollen lands on stigma a tube grows down the style to an ovule.

49 b) The fertilized zygote develops into a seed.

50 c) The ovary that surrounds the ovules develops into a fruit.

51 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.
