ATAR 11 Human Biology - Unit 1 EXAMrevision
Golgi body - correct answer ✔✔Modifies proteins and packages them in vesicles for secretion from the
cell
Cell membrane - correct answer ✔✔Determines which substances get into and out of the cell
Cytoplasm - correct answer ✔✔The jellylike material that makes up much of a cell inside the cell
membrane
Centrioles - correct answer ✔✔Involved in the reproduction of the cell (mitosis)
Endoplasmic reticulum - correct answer ✔✔Provides a surface on which chemical reactions can occur
Made of lipid molecules and associated proteins
Ribosomes - correct answer ✔✔The cell structures that make proteins
Amino acids are joined at the ____ to make proteins
Cytoskeleton - correct answer ✔✔Gives the cell it's shape because of microfilaments and microtubules
in it that assists with movement of materials, organelle or the whole cell
Lysosomes - correct answer ✔✔Small spheres that contain enzymes that break down proteins, lipids,
nucleic acid and some carbohydrates
Breaks down materials taken into the cell or breaks down worn out organelles
Nucleus - correct answer ✔✔Is the "brain" of the cell
- Contains genetic material
- Controls the cell
,Mitochondria - correct answer ✔✔Releases energy for the cell through respiration
Called the 'powerhouse of the cell'
Differentially permeable - correct answer ✔✔Certain ions and molecules can pass through the cell
membrane
Active process - correct answer ✔✔Process that requires the cell's energy
Passive process - correct answer ✔✔Cell's energy from respiration doesn't have to be used
Diffusion - correct answer ✔✔A passive process resulting from the random movement of ions and
molecules
Osmosis - correct answer ✔✔A passive, special case of diffusion where water crosses across the
membrane
Carrier-mediated transport - correct answer ✔✔A process that requires special proteins in the cell
membrane
May be passive or active depending on nature of mechanism
Vesicular transport - correct answer ✔✔A process in which materials are moved in membrane bound
sacs
Is an active process
Endocytosis - correct answer ✔✔Taking liquids or solids into cell by vesicular transport
Exocytosis - correct answer ✔✔When contents of a vesicle are passed to the outside
Tissues - correct answer ✔✔The second structural level
, Groups of muscles cells make up muscle, groups of nerve cells make up nerves and groups of organ cells
make up organs
Organs - correct answer ✔✔The third structural level
Different tissues work together to form organs
Made up of two or more tissues
System - correct answer ✔✔Highest structural level
A group of organs that work together for a common purpose
Epithelial tissue - correct answer ✔✔A covering or lining tissue
- Organs like the kidneys, heart, intestines and lungs are lines with epithelium
- Also lines inside of organs
Connective tissue - correct answer ✔✔Provides support for the body and helps to hold all body parts
together
The cells are not close together
- Separated from each other by large amounts of material that is not made of cells called matrix
Muscular tissue - correct answer ✔✔Log and thin, often called muscle fibres
Able to respond to a stimulus by becoming shorter
Three types
- Skeletal muscle
- Involuntary muscle
- Cardiac muscle
Nervous tissue - correct answer ✔✔Made up of nuerons
- Found in the brain, spinal cord and the nerves
