1 Plants J.Sample 2015

2 Review Photosynthesis: The process that plants use to make food using energy from the sun. Requires – Sunlight – Water – Carbon Dioxide – Chlorophyll Produces – Sugar in the form of glucose – Oxygen

3 Parts of a Plant Flower: – Produces seeds Leaves: – Produce food using photosynthesis Stem: – Supports the plant – Transports water and food Roots: – Anchor plant in ground – Absorb water and nutrients from the soil

4 Parts of a Flower Stigma – Stick top of pistil, accepts pollen Pistil – Female part of the flower Stamen – Male part, makes pollen Petal – Attracts pollinators Sepal – Leaf like part that protects the bud Bud – Young flower

5 Parts of a Flower Ovary – Round bottom of a flower where seeds form. Ovule – Inner part of the ovary the contains the eggs that will become seeds

6 Pollination Fertilization Pollination: – When pollen from the stamens is transferred to the stigma. Fertilization – When the pollen unites with the egg in the ovary and forms seeds.

7 Cells All living things are made of cells. Cells carry all life processes. New cells come from existing cells A cell is the smallest unit of a living thing that can carry out the basic processes of life.

8 Cells Most cells are to small to be seen with the naked eye. A microscope can make many parts of a cell visible. An egg is an example of a large cell, giant squid can have nerve cells up to 36 feet long.

9 Cell Divison New cells come from existing cells. The process of cell division is called mitosis.

10 Plant Cells Tend to be rectangular Cell Wall – Thick, rigid layer of fiber that provides shape and support Cell Membrane – Layer of protein and fat just inside the cell wall, gate keeper Vacuole – Holds liquids, (water), in the cell, helps cell maintain its shape. Chloroplast – Convert sunlight into energy through photosynthesis. Cytoplasm – Jelly like material that contains a cell’s organelles, (parts). Nucleus – The main control center of a cell, its “brain”.

11 Animal Cell Spherical or irregular shapes Cell Membrane Nucleus Cytoplasm Vacuole Mitochondria – Convert energy into sugars and starches – Also found in plants

12 Animal V. Plant Cells Make a Venn diagram.

13 Grouping Things are grouped according to characteristics. – Breakfast food vs dinner food – Summer clothes vs winter clothes – Living vs non living Living things are categorized as plant and animal Animals are further separated into vertebrate and invertebrate. Plants into vascular and nonvascular

14 Invertebrates Animals are differentiated from plants because most can move freely. Invertebrates are animals without back bones (vertebrae) Invertebrates make up 97% of the animal kingdom Common invertebrates are insects, worms, crustaceans, mollusks

15 Vertebrates Animals with backbones B-FARM – Birds – Fish – Amphibians – Reptiles – Mammals

16 Vascular Plants Have vascular tissues – Tubes to distribute water and food through out a plant. This allows vascular plants to get much bigger than nonvascular plants.

17 Nonvascular Plants Do not have vascular bundles to transport food and water Are much smaller than vascular plants. – Mosses – Fungi – Molds
