Cell Vocabulary
1. Cell Theory (Pg. 395)
– All living things are made of one or more cells, the cell is the smallest unit of life, and all new cells come from preexisting cells.
2. Levels of Organization (Pg. 419-426)
Cells – (use cell theory def.) smallest unit of life, what all living things are made of
Tissues – (Pg. 423) groups of similar types of cells that work together to carry out specific tasks. 4 main types include muscle, connective, nervous, and epithelial
Organs
– (Pg. 424) groups of different tissues that work together to perform a particular job.
Organ Systems
– (Pg. 425) groups of different organs that work together to complete a series of tasks
Organisms – (Pg. 426) group of organ systems working together to carry out all the jobs needed for survival
3.
Copy the Sequence Chart on Pg. 425 and fill in the blanks.
Cells are organized in tissues.
Different tissues working together to perform a particular job are called organs.
Groups of organs that work together to complete a series of tasks are called organ systems.
Many organ systems working together make up an organism.
4. Basic Characteristics of Cells – (Pg. 419-421)
Prokaryotic – cell without a membrane-bound nucleus
Eukaryotic
– cell that has a nucleus surrounded by a membrane & may other specialized organelles
Unicellular – organism made up of only one cell (amoeba, paramecium, algae, fungus)
Multicellular – organism made up of many eukaryotic cells working together

5. Cell Model (Pg. 406-412)
Cell Membrane – flexible covering that protects the inside of a cell from the environment outside a cell
Cell Wall
– stiff structure outside the cell membrane (only plant cell)
Cytoplasm – fluid inside a cell that contains salt and other molecules including the cytoskeleton
Cytoskeleton – network of threadlike proteins that are joined together to form a framework inside the cell, gives the cell shape and helps it move.
Nucleus – part of a eukaryotic cell that directs cell activities & contains genetic information stored in
DNA, directs all cell activity
Mitochondrion – (Pg. 411) organelles that process energy, makes fuel for the cells for growth, cell division, and material transport.
Ribosome – (Pg. 411) make proteins, not surrounded by a membrane, located in cell’s cytoplasm or attached to the endoplasmic reticulum (ER).
Golgi Apparatus – (Pg. 412) prepares proteins for their specific jobs or functions, then packages the proteins into tiny, membrane-bound, ball like-structures called vesicles.
Vesicle – (Pg. 412) organelles that transport substances from one area of a cell to another.
Rough Endoplasmic Reticulum – (Pg. 411) web like organelle that spreads from the nucleus throughout the cytoplasm, ER with ribosomes is rough, site of protein production
Smooth Endoplasmic Reticulum – (Pg. 411) ER without ribosomes is smooth, makes lipids such as cholesterol, helps remove harmful substances from a cell.
Central Vacuole – (Pg. 412) one large vacuole in a plant cell that stores water and other substances
Chloroplast
– membrane-bound organelles that use light energy and make food (glucose) from water and CO2 in photosynthesis
Vacuole
– (Pg. 412) organelles that store food, water, and waste material
6. Which structures do BOTH plant and animal cells have? Mitochondrion, ribosomes, vesicles, nucleus, Golgi apparatus, cell membrane, cytoskeleton, cytoplasm, smooth ER, rough ER
7. Which structures do only animal cells have? Lysosome, centriole
8. Which structures do only plant cells have? Chloroplasts, central vacuole, cell wall

9. Draw and label the structures of a plant cell (Pg. 407).
10. Draw and label the structures of an animal cell (Pg. 408).

Photosynthesis (Pg. 43) –
11. Plant Responses to Stimuli (Pg. 490-493)
Stimuli –
Tropism
–
12. Give 3 examples of environmental stimuli to which a plant might respond.
Phototropism –
Geotropism –
13. Copy the Chart on Pg. 493 and fill in the answers for A-E.
14. Animal Reponses to Stimuli (Pg. 502-506).
Behavior
–
Homeostasis
–
15. Give 3 examples of external stimuli to which an animal might respond.

16. Give 3 examples of internal stimuli to which an animal might respond.
17. Give 2 examples of how animals respond to illness to maintain homeostasis (Pg. 503).
Fight or flight
–
Response to internal stimuli - wilting in plants and emergence of seedlings, turgor pressure, autotrophic – heterotrophic
– sexual reproduction (Pg. 548) – asexual reproduction (Pg. 562) –
Functions of organisms, adaptations – gills, hollow bones, xylem in plants (Pg. 376)
