Living Organisms share six Characteristics.1. Getting energy 2. Using energy 3. Growing 4. Reproducing5. Getting rid of waste 6. Reacting to outside change

Organism – Any living thing that maintains processes of life

Cell – The basic unit of structure for all living things

Cells are Building Blocks

Organism

There are around 2.5 billion cells in one of your hands. If every cell in your hand was the size of a grain of sand, your hand would be the size of a school bus. There are over 200 cell types in the body.

There are many different kinds of cells!

Animal Cell •Cell membrane (orange)

•Cytoplasm (yellow)

•Nucleus (red)

•Vacuoles (Blue)

•Mitochondria (Purple)

Parts of an Animal CellScience Book pages 54-57

Organelle (little organs) – specialized structures inside a living cell where all activities are carried out

Cell Membrane – a thin covering that surrounds every cell, it protects the cell, holds it together, and controls what goes in and out

Nucleus – directs all cell activities. This is where the chromosomes that contain information about the cell are found.

Cytoplasm – contains chemicals that keeps the cell healthy. There are organelles suspended in the cytoplasm like… Mitochondria -powerhouse that releases energy from nutrients Vacuoles – store nutrients, water, and waste, until they are used or released

DNA - carries the genetic information for a cell and is a set of instructions that tells the cell what to do or be.

Chromosome – a single long molecule of DNA.

Cell Wall (Brown)

Plant cells have structures not found in animal cells.

* Cell wall – helps support the plant cell. It is outside of the cell membrane.

* Chloroplasts – make food for plant cells using chlorophyll.

* Chlorophyll – a green pigment that allows the plant to absorb light energy that it needs for photosynthesis.

3D Cell Model Dear 5th Grade Families,

As we discuss cells, students will be creating a 3D model of a plant cell. The requirements are as follows:Students must make a 3D model of a plant cell using the materials of their choice. Be creative! Please no food products! Include and label the following parts: cell membrane, cell wall, nucleus, mitochondria, vacuole, chloroplast, and cytoplasm. The plant cell must be completed and brought to school on Thursday, November 14th. No late or early projects will be accepted. I fully expect that fifth graders will do this project on their own. Please choose materials and processes that can be done without assistance. These projects will be graded based on fifth grade ability. Please contact me with any questions. I look forward to seeing the students’ creativity!! -Miss Elder

Cilia and flagella are used to help the cell move itself.

Bacteria!!

Amoeba – is an animal like cell (protozoa)

many amoebas are predators and hunt by stretching out their cytoplasm to surround an envelope prey, and then break it down into nutrients. Many amoebas are parasites (harm other organisms by feeding off of them).

Diseases caused by amoebas and other protozoa.

Malaria

African sleeping sicknessChagas’ disease

Leishmaniasis

Diatoms – single celled organisms that are plant like.

Diatoms have chloroplasts and make their own food. This type of algae produce a lot of Earth’s oxygen. They are also produce a lot of food for ocean life.

Robert Hooke• Discovered cells when he looked at a thin slice

of cork through a microscope 300 years ago• As he was looking through the microscope, he

noticed a pattern of small rectangular box-like squares in the cork – reminded him of little rooms

• He named these “cells” after the Latin word for room, cella.

Ernest Just• African-American born in SC in 1883• Majored in Biology• Made discoveries about cells after

microscopes became stronger.• Discovered that there were other parts of the

cell besides the nucleus did.• Was able to discover whether or not a cell

functioned properly or not
