Biology I H - 1St Semester Exam - Chapter 4

Front 1

Small, spherical organelles that digests proteins, carbohydrates, lipids, and nucleic acids. It can also digest old, worn-out organelles, bacteria an viruses

Back 1

Lysosome

Front 2

Large organelles scattered throughout the cytoplasm. It is referred to as the "Powerhouse." They are numerous in a cell and change organic compounds into energy.

Back 2

Mitochondria

Front 3

Fluid-filled organelles that store enzymes and wastes. They are quite large in size and may take up 90% of cells's volume

Back 3

Vacuoles

Front 4

Organelle of a cell responsible for processing, packaging, and secreting. System of membranes that look like flattened sacs.

Back 4

Golgi Apparatus (Golgi Body)

Front 5

Controls the ease with which substances move in and out of the cell

Back 5

Cell Membrane

Front 6

- Most numerous organelle
- does not have a membrane around the organelle
- made of protein and RNA
- Help synthesis (produce) other proteins
- found free in cytoplasm or attached to the endoplasmic
reticulum

Back 6

Ribosome

Front 7

- Found in plant cells; not animal cells
- rigid structure that lies outside of the cell membrane
- supports and protects the cell

Back 7

Cell Wall

Front 8

- system of tubes and sacs
- intracellular highway which moves molecules from one cell
to another cell
- has ribosomes attached to it
- plentiful in cells that make a lot of proteins

Back 8

Rough Endoplasmic Reticulum

Front 9

- system of tubes and sacs
- intracellular highway which moves molecules from one
cell to another cell
- no ribosomes attached
- produces steroids, regulates calcium, and brakes down
toxins

Back 9

Smooth Endoplasmic Reticulum

Front 10

- region of a cell between the cell membrane and the nucleus
- contain cytosol
- contains salts, minerals, and organic molecules
- contains all organelles

Back 10

Cytoplasm

Front 11

- most prominent structure in a eukaryotic cell
- stores hereditary information in its DNA
- Also contains RNA

Back 11

Nucleus

Front 12

- lack a membrane-bound nucleus and/or membrane-bound organelles
- are unicellular

Back 12

Prokaryotic cells

Front 13

- have a membrane-bound nucleus and organelles
- found mostly in multicellular organisms

Back 13

Eukaryotic cells

Front 14

Cells are organized into _______

Back 14

tissues

Front 15

Tissues are organized into ______

Back 15

organs

Front 16

Organs are organized into _______

Back 16

systems
