Capsule

Plasmids❏ Small DNA molecule that is separate

from the from the chromosomes❏ Replicate independently❏ “Naked” → Not wrapped in histones

Nucleus❏ Contains Deoxyribonucleic Acid (DNA)❏ Houses the nucleolus, site of rRna

synthesis❏ The nuclear envelope contains nuclear

pores, that allows RNA to leave the nucleus

❏ Site of DNA replication, repair, and transcription

Endoplasmic Reticulum (ER)❏ Smooth Endoplasmic

Reticulum: No ribosomes embedded; site of lipid and steroid hormone synthesis

❏ Rough Endoplasmic Reticulum: Embedded with ribosomes; site of glycoprotein synthesis (attaches sugar groups to amino acid chains)

Ribosomes

❏ Assemble amino acids into polypeptide chains

❏ Prokaryotic: 70s ribosomes (30s subunit + 50s subunit)

❏ Eukaryotic: 80s ribosomes (40s subunit + 60s subunit)

Golgi Complex❏ Flatten sacs (cisternae)❏ Modification of

proteins and lipids ❏ Package modified

proteins and lipids into vesicles for transport

Vacuoles❏ Food Vacuole: Temporary storage

of nutrients; merges with lysosomes to digest the nutrients

❏ Central Vacuole: Large organelle that occupies most of a plant’s interior; exerts pressure onto cell wall, giving it shape

Vesicle❏ Move materials

between organelles and plasma membrane.

Cytoplasm❏ Composed of mostly water

and salt❏ Site of anaerobic respiration

(glycolysis and fermentation)❏ Gives the cell its shape; holds

the organelles in place❏ Cytosol: Part of cytoplasm

that doesn’t contain organelles

Plasma Membrane❏ Double phospholipid membrane❏ Barrier between internal

metabolic events from the external environment

Lysosomes❏ Vesicles from the golgi

apparatus that contains digestive enzymes

❏ The enzymes only function in acidic environment → If the enzyme is released into the cell, the enzyme is rendered useless

Peroxisomes❏ Break down substances

(lipids and proteins); also breaks down hydrogen peroxide

❏ Toxins are broken down by peroxisomes

Mitochondria❏ Synthesizes ATP❏ Site of aerobic

respiration (requires oxygen)

Chloroplast❏ Site of

photosynthesis❏ Light

dependent/light independent reaction

Cytoskeleton

❏ Microtubule (tubulin): Cell motility (flagella and cilia), mitotic spindle, cell structure, organelle movement

❏ Intermediate Filaments: Cell structure❏ Microfilaments (actin): Muscle

contraction (w. protein myosin), cytokinesis

Centrioles

❏ Work with microtubules during mitosis/meiosis to form spindle

apparatus.

Flagella and Cilia ❏ Composed of

microtubules❏ Facilitate cell

movement❏ Flagella: Few, long, snake-like movement❏ Cilia: Many, short, hair-like, back-and-

forth movement.

Extracellular Matrix❏ Area between

adjacent cells❏ Binds adjacent cells

together❏ Structural proteins,

adhesion proteins, glycoproteins
