Cell Organelles
SPI 0707.1.1
Identify and describe the function of the major plant and animal cell
organelles.
•Cell Structures
• A few major Organelles:
• Nucleus- Control Center
• Cell Membrane- controls what enters and leaves the cell
• Ribosome- Makes proteins
• Endoplasmic Reticulum- Smooth and Rough; packages and
transports proteins
• Cytoskeleton- web of proteins that provides structure.
• Cytoplasm- thick fluid that hold organelles
• Vacuole- packages and sends materials to other cells
• Mitochondria- creates energy for the cell (Cellular Respiration)
• Chloropasts- only in plant cells. Makes food for the cell
(Photosynthesis)
• Cell Wall- Only in plant cells. Gives extra support for the cell.
•
•
•
•
•
ER: passageway, rough has ribosomes (protein)
Vacuole: helps digestion, stores waste
Lysosome: digests food, waste, cell parts
Mitochondria: makes energy (ATP) & breaks down food
Plants have cell wall, chloroplasts, & 1 large vacuole

Which of these correctly identifies a cell organelle and its
function?
•
•
•
•
a.The nucleus temporarily stores materials.
b.The ribosome makes proteins.
c.The vacuole performs cellular respiration.
d.The Golgi complex converts light energy into chemical energy.

Mitosis vs. Meiosis
SPI 0707.1.4
Sequence a series of diagrams that depict chromosome
movement during plant cell division.
•Mitosis
• Stages of the Cell Cycle
• Interphase- the cell is growing and DNA is copying.
• Mitosis
• Prophase- DNA condenses into chromosomes
• Metaphase- Chromosomes line up in the middle.
• Anaphase- Chromosomes split and are pulled to
opposite sides of the cell.
• Telophase- Two new nuclei form and DNA
decondenses.
• Cytokinesis- The cell has divided and begins to grow.
•
•
•
•
•
During this phase of mitosis, new chromosomes stretch out, a
new nucleus forms around each set of chromosomes, and a
new cell membrane begins to form:
A Prophase
B Metaphase
C Anaphase
D Telophase
•
• Interphase, Prophase, Metaphase, Anaphase, Telophase,
Cytokinesis
• Chromosomes copy, condense, align, separate, unwind,
new nuclear membrane, 2 identical cells

Human Body Systems
SPI 0707.1.3
Explain the basic functions of a major organ system.
•
Amoeba Sisters Human Body Systems
• Cardiovascular: carries oxygen-rich blood through body (to
and from heart)
• Nervous: receives & sends electrical messages from
surroundings (brain)
• Lymphatic/ immune: protect against bacteria, viruses,
invaders
• Respiratory: includes lungs, take in O2 and release CO2
• Skeletal/ muscular: work together to protect organs, create
movement
