General Biology Finals 1

Cell Membrane

Outer layer of the cell, composed of layer of double layer of phospholipids in which proteins are embedded

Cell membrane 2

Controls and regulates the passage of substances in ans out of the cell

Cytoplasm

The living matter within the cell and has fluid and jelly like substance called hyaloplasm

Cytoplasm 2

Membrane bound organelles and other substances need by the cells are dispersed in

Nucleus

Has liquid portion called karyolymph where chromatin materials and nucleolus are found

Ribosomes

Synthesis protein molecules that maybe used to build cell structures or to functions as enzymes

Endoplasmic reticulum

Series of membranous channel that forms a continuous network extending from the cell membrane to the nucleus

Rough er

Associated with active protein synthesis process

Smooth er

Does not contain ribosome and is involved in the synthesis and transport of lipids and detoxification

Golgi apparatus

Formation of lysosomes and other transport vesicles of the cells

Mitochondria

Cristae, own DNA, releases energy from food molecules transform it into ATP

Chloroplast

Double membrane organelles inner folds thylakoids

Light energy to chemical energy

Lysosome

Digestion of nutrients , bacteria and damaged cells

Peroxisome

Contain enzymes

Break down fatty acids and transfer hydrogen into Oxygen to hydrogen peroxide to water

Vacuoles

Store and release substances in cytoplasm cell enlargement and water balance

Centriole

Small set of microtubes 9 groups

Cytoskeleton

Used in maintenance of cell shape

Centrosomes

Only in animal cell

Organize microtubes and provide structure for cell wall pull chromatids apart in cell division

Cilia

Little shits

Flagella

Has a tail

Fibrils and microtubes

Transport materials within the cytoplasm

Nucleus

Controls or regulates all chemical reaction within the cells

Nuclear envelope

Made up of two lipid bilayer membranes

Nuclear pore

Are protein based channels in the nuclear envelope

Nucleolus

Made up of proteins and ribonucleic acids

Rewrite ribosomal

Chromatin

DNA + HISTONE =

Double helix in nucleus

Cell wall

The outmost layer of a plant cell provide support to the body

Plastids

Found only plants a site of photosynthesis and storage of cornstarch

Chloroplastids

Green pigments

Xantophylls

Yellow pigments

Carotenes

Orange pigments

Leucoplastids

Colorless pigments
