2
In this lesson, we will… Distinguish between the basic structures and functions of plant and animal cells. (GLE ) Identify the major parts of plant and animal cells, such as, the nucleus, cell membrane, cell wall, and cytoplasm. (SPI ) Compare and contrast basic structures and functions of plant and animal cells. (SPI )

Lesson 1 Vocabulary organism unicellular multicellular chlorophyll
cell membrane cytoplasm nucleus cell wall
4
Name some things that have parts.
A house A school Football stadium A hospital A car A clock
5
What are the parts of a school?
Cafeteria Library Office Classrooms Bathrooms Gymnasium Auditorium Band room How are these rooms used?
6
What is the difference between…
A frog cell and an plant cell?
7
What are cells? An organism is a living thing made of the same tiny building blocks called cells. Cells are the smallest unit of living things that can carry out the basic processes of life.
8
What are Cells? Cells come from other cells dividing or splitting into other cells.
9
What are cells? Unicellular, or one- celled, organisms are made up of a single cell that carries out its life processes. Life processes include growing, getting food, reproducing, and responding to the environment.
10
What are cells? Cells that have many cells are called multicellular.
Multicellular organisms include frogs, trees, and YOU! In multicellular organisms, each cell has its own job to do.
11
What are cells? Cells of multicellular organisms work together to take care of different functions of the organism. Example: Heart muscle cells work together to keep your heart beating.
12
What are cells? Scientist have identified more than 1 ½ million different kinds of organisms. They estimate that there are more than 1 billion kinds of unicellular organisms.
13
Question # 1 All organisms, or living things, are made of __________.
Cells Cool stuff unicellular
14
Question # 2 Every cell in every living thing comes from another cell that ______________. Had a baby Was here at the beginning of time Splits or divides Was created
15
Question # 3 A single-celled organism that can carry on all its life processes is called ____________. unicellular One of a kind One multicellular cell
16
Question # 4 Organisms made up of more than one cell are called ________________. Unicellular One of a kind Multicellular Cell
17
Question # 5 Scientists have identified more than ________ different kinds of organisms. 1,000,000 1,000,000,000 100 cells
18
Question # 6 Scientists estimate there may be more than ________ kinds of unicellular organisms. 1 million 1 billion 1 hundred 10
19
What is inside the animal cell?
All organisms are made of cells. Your body has more than 200 different kinds of cells. Plant and animal cells have several basic structures, called organelles, to help them perform life processes.
20
What is inside an animal cell?
nucleus cytoplasm Cell membrane mitochondria vacuoles Animal Cell Organelles: Cell Membrane Cytoplasm Nucleus Mitochondria Vacuoles
21
What is inside an animal cell?
Cell Membrane Flexible wrapping surrounding animal cells Gives the cell shape Controls what materials move into and out of the cell Only certain material are able to enter and leave the cell Cell membrane
22
What is inside an animal cell?
Cytoplasm Gel-like liquid that fills cells Made of mostly water A variety of organelles float in the cytoplasm Supports cell’s structures Constantly moves like a stream Some cell life processes take place in the cytoplasm cytoplasm
23
What is inside an animal cell?
Nucleus: Cell’s control center – the BOSS! Large, round organelle Usually in the center of the cell Has a membrane with pores, or openings, to allow certain materials to pass in or out Sends signals to all other parts of the cell with instructions nucleus
24
What is inside an animal cell?
Mitochondria: Oval, membrane- covered organelle Supplies energy for the cell Tiny power plant Break down food, which releases energy for the cell Some cells use more energy than others Cells requiring more energy usually have many mitochondria mitochondria
25
What is inside an animal cell?
Vacuole: Used for storage Stores water, food, and wastes Nucleus can signal the vacuole to release whatever it is storing Some animal cells have small vacuoles Some animal cells may not have any vacuoles vacuoles
26
Question # 7 Both plant and animal cells perform life processes by using ___________. Its parts Cell division organelles multicellular
27
Question # 8 All cells are surrounded by a(n) _________ that controls the materials that move in and out of the cell. mitochondria Cell membrane nucleus vacuole
28
Question # 9 The region between the cell membrane and the nucleus is filled with ________. mitochondria Cell membrane nucleus cytoplasm
29
Question # 10 The cell’s control center is called the ________.
mitochondria Cell membrane nucleus cytoplasm
30
Draw and label a diagram of an animal cell.
nucleus cytoplasm cell membrane mitochondria vacuoles
31
Lab: What substances affect cell membranes?
Inquiry Skill: Experiment Follow the steps on pages in your text to complete the experiment. Record your findings in your scientist notebook.
32
What is inside the plant cell?
vacuole nucleus chloroplasts cell membrane cell wall cytoplasm Plant cells have many of the same organelles as animal cells. often have a box-like shape are often a bit larger than animal cells have additional organelles that animal cells do not have mitochondria
33
What is inside the plant cell?
vacuole nucleus chloroplasts cell membrane cell wall cytoplasm Plant cell organelles Nucleus Cell membrane Vacuole Cytoplasm Mitochondria Chloroplast Cell wall mitochondria
34
What is inside the plant cell?
Cell wall Additional outer covering, outside the cell membrane Stiff structure Provides strength and extra support cell wall
35
What is inside the plant cell?
Vacuole Unlike animal cells, plants usually have one LARGE central vacuole. Stores excess water to keep the plant from drying out Releases extra water when the plant needs it Provides extra support vacuole
36
What is inside the plant cell?
Chloroplast Plants make their own food inside chloroplasts Green structure Energy from the sunlight is used to produce food for the plant inside the chloroplast Plants are green because they contain a green chemical, chlorophyll chloroplasts
37
What is inside the plant cell?
Chloroplast Chlorophyll is able to use the energy in sunlight to make food Plants that do not have chloroplasts (with the green chemical chlorophyll), are not green. Chloroplasts are mainly found in the cells of leaves and stems of plants. chloroplasts
38
Question # 11 The food making factory of plants is the ______________.
mitochondria chloroplast nucleus cytoplasm
39
Question # 12 The green chemical inside the chloroplast is called __________. cytoplasm chloroplast nucleus chlorophyll
40
Question # 13 Chloroplast use energy from the ________ to make food.
vacuole mitochondria sun chlorophyll
41
Question # 14 Which organelle does the plant cell have but the animal does not? vacuole mitochondria cell wall cytoplasm
42
Question # 15 Which organelle does the plant cell have but the animal does not? chloroplast mitochondria cell membrane cytoplasm
43
Question # 16 Which organelle is the control center for the plant?
chloroplast mitochondria nucleus vacuole
44
Question # 17 Which organelle supplies energy for the cell?
chloroplast mitochondria nucleus vacuole
45
Draw and label a diagram of a plant cell.
vacuole nucleus chloroplasts cell membrane cell wall cytoplasm mitochondria
46
Draw a Venn Diagram showing the similarities and differences of plant and animal cells.
Plant cells Animal cells
47
How are cells organized?
Unicellular organisms – have only one cell that performs all life processes. Multicellular organisms – contains many different types of cells that have specific functions.
48
How are cells organized?
Similar cells working together at the same job, or function, form a tissue. A group of tissues that work together to perform a special function form an organ. cell tissue organ organ system
49
How are cells organized?
Organs that work together to perform a certain function make up an organ system. All of the cells, tissues, organs, and organ systems form an organism. cell tissue organ organ system
50
Question # 18 Organs that work together to do a certain job are called a(n) ______________. cell tissue organ organ system
51
Question # 19 Similar cells working together at the same job form a ______________. cell tissue organ organ system
52
Question # 20 A group of tissues that work together to perform a special function form a(n) ________. cell tissue organ organ system
53
Activity: Foldable Make a Three-Tab book. Use these titles:
Cells Organelles Tissues, organs, and organ systems Tell about each topic on the inside of each tab.
