ATI Teas 7 Biology Exam Questions And
Answers (Guaranteed A+)
The cell Theory - answer✔1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells arise from pre-existing cells.
prokaryotic cells - answer✔- single-celled organisms
- do not have a nucleus
Eukaryotic cells - answer✔- one or more celled organism
- have nucleus
Nucleus - answer✔- Control center of the cell that contains DNA
- controls the cell functions
- regulates cell growth & metabolism
Nucleoli (makes ribosomes) - answer✔within the nucleus, it makes ribosomes (protein
synthesis)
Ribosomes (protein synthesis) - answer✔site of protein synthesis
- spherical shaped cell organelle
- non-membrane organelle
- do NOT have DNA
- composed of RNA and certain proteins
- found in plant and animal cell
Vacuole (stores) - answer✔stores water & cellular waste
Golgi Complex/Apparatus (packages) - answer✔A cell organelle that helps make and package
materials to be transported out of the cell.

Mitochondria - answer✔- generates energy for the cell (ATP)
- uses enzymes found on cristae to release energy through catabolism
- oval-shaped organelle
- consist of an inner & outer membrane
- has its own DNA
- contains folds called cristae
- found in both plant and animal cells
Chloroplast - answer✔uses photosynthesis to produce ATP(energy)
- oval-shaped organelle
- consist of an inner & outer membrane
- has its own DNA
- does NOT have folds called cristae
- found in only plant cells
Rough Endoplasmic Reticulum - answer✔- has ribosomes
- makes proteins
Smooth Endoplasmic Reticulum - answer✔- no ribosomes
- makes lipids
Lysosomes - answer✔An organelle containing digestive enzymes
- sac like organelle
- single membrane
- lacks cristae & DNA
- presents inside animal cells but rarely found in plant cells
Cell membrane (plasma membrane) - answer✔The cell membrane is semi-permeable, meaning
the cell structure that controls what materials can enter or leave the cell.
the semi-permeable structure is made of a phospholipid bilayer.
